Safety Rules
QUIETPACT™ 75D Recreational Vehicle Generator
SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe
operation be copied and posted in potential hazard areas of the recreational vehicle.
Safety should be stressed to all operators and potential operators of this equipment.
!
!
• The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentra-
tions, can cause unconsciousness or even death.
Never operate the generator set with the vehicle
inside any garage or other enclosed area. DO NOT
OPERATE THE GENERATOR IF THE EXHAUST
SYSTEM IS LEAKING OR HAS BEEN DAMAGED.
SYMPTOMS OF CARBON MONOXIDE POISON-
ING ARE (a) inability to think coherently, (b) nau-
sea, (c) vomiting, (d) twitching muscles, (e) throb-
bing temples, (f) dizziness, (g) headaches, (h)
weakness, and (i) sleepiness. IF EXPERIENCING
ANY OF THESE SYMPTOMS, MOVE INTO FRESH
AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET
MEDICAL HELP. Shut down the generator and do
not operate it until it has been inspected and
repaired.
• Never sleep in the vehicle while the genset is run-
ning unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installation
manual. Make sure there is ample fresh air when
operating the genset in a confined area.
• The engine exhaust fumes contain carbon monox-
ide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. Thus, the exhaust
system must be installed properly, in strict com-
pliance with applicable codes and standards.
Following installation, do nothing that might ren-
der the system unsafe or in noncompliance with
such codes and standards. The generator com-
partment must be completely vapor-sealed from
the vehicle interior. There must be no possibility of
exhaust fumes entering the vehicle interior. Never
operate this equipment with a leaking or defective
exhaust system.
!
!
!
WARNING:
The engine exhaust from this product
contains chemicals known to the state
of California to cause cancer, birth
defects, or other reproductive harm.
!
WARNING:
This product contains or emits chemicals
known to the state of California to cause
cancer, birth defects or other reproductive harm.
Study these SAFETY RULES carefully before
installing, operating, or servicing this equipment.
Become familiar with this manual and with the unit.
The generator can operate safely, efficiently, and reli-
ably only if it is properly installed, operated, and
maintained. Many accidents are caused by failing to
follow simple and fundamental rules or precautions.
Generac cannot possibly anticipate every possible cir
cumstance that might involve a hazard. The warn-
ings in this manual, and on tags and decals
affixed to the unit, are, therefore, not all-inclusive. If
using a procedure, work method, or operating tech-
nique that Generac does not specifically recommend,
ensure that it is safe for others. Also make sure the
procedure, work method, or operating technique
chosen does not render the generator unsafe.
DANGER
Despite the safe design of this generator,
!
operating this equipment imprudently, neglect-
ing its maintenance, or being careless can cause
possible injury or death. Permit only responsi-
ble and capable persons to operate and main-
tain this equipment.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit is
operating.
Parts of the generator are rotating and/or hot
during operation. Exercise care near running
!
generators.
• Adequate, unobstructed flow of cooling and venti-
lating air is critical to correct generator operation
and is required to expel toxic fumes and fuel
vapors from the generator compartment. Without
sufficient cooling airflow, the engine/generator
quickly overheats, which seriously damages the
generator. Do not alter the installation or permit
even partial blockage of ventilation provisions, as
this can also seriously affect the safe operation of
the generator.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.
!
!
GENERAL HAZARDS
• For safety reasons, Generac recommends
that the installation, initial startup, and mainte-
nance of this equipment be performed by a
Generac Authorized Service Dealer.

Section 1 – General Information
QUIETPACT™ 75D Recreational Vehicle Generator
1.2 GENERATOR APPLICABILITY
1.4 GENERATOR AC
These generators have been designed and manufac-
tured for supplying electrical power to recreational
vehicles. DO NOT modify the generator nor use it for
any application other than for what it was designed.
If there are any questions pertaining to its applica-
tion, write or call the factory. Do not use the unit until
advised by a competent authority.
CONNECTION SYSTEM
This generator is equipped with dual-stator AC
power windings. These two-stator windings supply
electrical power to customer electrical loads by
means of a dual, two-wire connection system. Note,
however, that the neutral is grounded.
The generator may have been installed so that it pow-
ers 120- and/or 240-volt AC electrical loads (Figure
1.1). It can be rewired to connect 120-volt AC electri-
cal loads only. This procedure should be done by a
Generac Authorized Service Dealer or other qualified
installer. Refer to the installation portion of this man-
ual for more information.
DANGER
For fire safety, the generator must have been
properly installed in compliance with NFPA 70
(latest edition), “National Electrical Code”,
Article 551, and NFPA 1192 (latest edition),
“Standard for Recreational Vehicles”. The gen-
erator also must have been installed in strict
compliance with the manufacturer’s detailed
installation instructions. After installation, do
nothing that might render the unit in noncom-
pliance with such codes, standards, and instruc-
tions.
Figure 1.1 – Connections for 120/240 Dual
Voltage
Use this generator to supply electrical power for
operating 120/240-volt, single-phase, 60-Hertz, AC
electrical loads. These loads can require up to 7,500
watts (7.5 kW) of power, but cannot exceed 62.5 AC
amps of current at 120 volts, or 31.2 AC amps at 240
volts.
Do not overload the generator. Some installa-
tions may require that electrical loads be alter-
1.5 SPECIFICATIONS
!
nated to avoid overloading. Applying exces-
sively high electrical loads may damage the
generator and shorten its life. Add up the rated
watts of all electrical lighting, appliance, tool,
and motor loads the generator will power at
one time. This total should not be greater than
the wattage capacity of the generator. If an
electrical device nameplate gives only volts and
amps, multiply volts times amps to obtain
watts (volts x amps = watts). Some electric
motors require more watts of power (or amps
of current) for starting than for continuous
operation.
1.5.1 FUEL REQUIREMENTS
◆
The generator is equipped with a diesel fuel system.
Use clean, fresh No. 1D or No. 2D diesel fuel with
minimum Cetane number of 40. The diesel fuel must
also conform to American Society of Testing and
Materials (ASTM) specifications. Never use any dirty
or contaminated fuel. When adding fuel, DO NOT
overfill the tank. Allow room at the top of the tank for
fuel expansion. Depending on the installation, the
generator may have either a separate fuel tank or
“share” the vehicle’s engine fuel tank.
NOTE:
Some installations using a “shared” fuel tank may
have a generator fuel pickup tube that is shorter
than the vehicle’s engine pickup tube. Such an
arrangement causes the generator engine to “run
out of fuel”, while adequate fuel for the vehicle
engine remains in the tank.
1.3 SAFETY
Before attempting to use the generator set, carefully
read the “Safety Rules” section of this manual.
Comply strictly with these rules to prevent accidents
and damage to equipment and/or property. We sug-
gest copying and posting the “Safety Rules” in poten-
tial hazard areas of the vehicle. Stress safety to all
operators and potential operators of this equipment.
Also, appropriate care should be taken in applica-
tions where extremely low ambient temperatures
are possible, to ensure the temperature of the
diesel fuel is not allowed to fall below levels where
“gelling” could occur

Section 2 – Operation
QUIETPACT™ 75D Recreational Vehicle Generator
2.1.4 LINE BREAKER
◆
2.1 GENERATOR CONTROL PANEL
The following features are mounted on the generator
control panel (Figure 2.1):
The line (i.e., main) breaker protects the generator’s
AC output circuit against overload and provides a
method of turning OFF the generator’s 120/240-volt
AC output to the vehicle circuits. The QUIETPACT™
75D has two 35-amp breakers.
Figure 2.1 – Generator Control Panel
NOTE:
Refer to Section 1.4, “Generator AC Connection
System,”. Individual installations will differ. If an
overload occurs, the dual breakers will open the
ungrounded (i.e., hot) stator leads (11 and 44 in
Figure 1.1). When the generator has been con-
nected for 120 volts only (Figure 2.16, Page 31),
the line breakers will operate independently on
the ungrounded (i.e., hot) stator leads (11 and 33
in Figure 2.16, Page 31).
2.1.5 PREHEAT SWITCH
◆
The diesel engine is equipped with glow plugs, one
for each cylinder. When the preheat switch is pressed,
the glow plugs heat the engine combustion chamber,
allowing for quicker starts when the engine is cold.
Pressing the preheat switch also operates the fuel
pump.
2.1.1 HOURMETER
◆
This indicates the length of time the engine/generator
has operated, in hours and tenths of hours. Use
the hourmeter to ensure that the periodic mainte-
nance tasks for the generator are completed on a
timely basis.
2.2 OPTIONAL REMOTE START/STOP
This generator is equipped with a plug-in connector
that can be interfaced with an optional remote panel
provided inside the vehicle. This option allows for
starting and stopping the generator conveniently
from within the vehicle. Refer to Part II - Installation
Instructions, Section 2.8, for details on the remote
start/stop option.
2.1.2 START/STOP SWITCH
◆
To crank and start the engine, hold this switch in the
START position. Release the switch when the engine
starts. To stop an operating engine, press and hold
the switch in the STOP position until the engine shuts
off. The switch’s center position is the RUN position.
2.3 BEFORE STARTING THE ENGINE
NOTE:
Instructions and information in this manual
assume the generator has been properly installed,
connected, serviced, tested and adjusted by a
qualified installation technician or installation
contractor.
2.1.3 FUSE
◆
The 14-amp fuse protects the engine’s DC control cir-
cuit against electrical overload. If the fuse element
has melted open due to overloading, the engine can-
not be cranked. If the fuse must be replaced, use only
an identical replacement (i.e., SFE-14).
2.3.1 INSTALLATION
◆
Generator installation must have been properly com-
pleted so that it complies with all applicable codes,
standards, and regulations and with the manufactur-
er's recommendations.
If a fuse element melts, find the cause of the
overload before replacing the fuse.

2.3.2 ENGINE LUBRICATION
◆
DANGER
Before starting the engine, have the engine crankcase
properly serviced with the recommended oil. Refer to
Section 1.5.3 and Sections 3.1 and 3.2 for oil servic-
ing procedures and recommendations.
The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concen-
trations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOX-
IDE POISONING ARE (a) inability to think coher-
ently, (b) nausea, (c) vomiting, (d) twitching
muscles, (e) throbbing temples, (f) dizziness, (g)
headaches, (h) weakness, and (i) sleepiness. IF
EXPERIENCING ANY OF THESE SYMPTOMS,
MOVE INTO FRESH AIR IMMEDIATELY. IF SYMP-
TOMS PERSIST, GET MEDICAL HELP. Shut down
the generator and do not operate it until it has
been inspected and repaired.
!
Any attempt to crank or start the engine before
it has been properly serviced it with the recom-
mended oil may result in an engine failure.
!
2.3.3 FUEL SUPPLY
The engine must have an adequate supply of proper
fuel to operate. Before starting it, check that sufficient
fuel is available.
◆
NOTE:
Depending on the installation, the generator may
have either a separate fuel tank or “share” the
vehicle’s engine fuel tank.
DANGER
Never sleep in the vehicle while the genset is
running unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installa-
tion manual. Make sure there is ample fresh air
when operating the genset in a confined area.
Some installations using a “shared” fuel tank may
have a generator fuel pickup tube that is shorter
than the vehicle’s engine pickup tube. Such an
arrangement causes the generator engine to “run
out of fuel”, while adequate fuel for the vehicle
engine remains in the tank.
!
2.4 STARTING THE GENERATOR
2.3.4 COOLANT LEVEL
◆
NOTE:
Check the engine coolant level prior to initial use and
at recommended intervals. Refer to Section 1.5.4,
“Coolant”, and Section 3.8, “Engine Coolant”, for pro-
cedures and recommendations.
Read the vehicle manufacturer’s instructions. The
owner/operator should become familiar with the
vehicle in which this generator is installed.
Differences exist between vehicles. For example,
some vehicles may use a transfer switch to isolate
dockside power from the generator, while other
vehicles may use an isolating receptacle. Some
vehicles may be equipped with a DC converter,
which allows the generator to power certain DC
lighting and other DC loads.
2.3.5 COOLING AND VENTILATING AIR
◆
Air inlet and outlet openings in the generator com-
partment must be open and unobstructed for con-
tinued proper operation. Without sufficient cooling
and ventilating airflow, the engine/generator may
overheat, causing engine shutdown and damage to
the generator.
To start the generator from either the generator con-
trol panel or from the optional remote panel, proceed
as follows:
2.3.6 ENGINE EXHAUST GAS
◆
1. Turn OFF electrical loads using the means pro-
vided in the vehicle (such as, a main-line circuit
breaker or transfer switch).
Before starting the generator engine, be sure there is
no way for exhaust gases to enter the vehicle interior
and endanger people or animals. Close windows,
doors, and other openings in the vehicle that, if open,
might permit exhaust gases to enter the vehicle.
NOTE:
If starting from the generator control panel, turn
OFF loads by setting the generator’s main-line
breaker to the OFF (or open) position. If starting
from a remote panel, turn OFF loads using the
means provided in the vehicle (such as, a main
circuit breaker). Electrical load circuits will be
turned ON, after the generator has started, stabi-
lized, and warmed up.

erator on the generator data decal located below the
user control panel.
◆
a maximum of 15 to 30 seconds.
3. While pressing the Preheat switch to crank the
engine, hold the engine Start/Stop switch in the
START position. When the engine starts, release
the switches.
Applying electrical loads in excess of the unit’s rated
capacity may trip the line breaker or cause the
engine/generator to shut down.
To avoid overloading, add up the wattage of all con-
nected electrical lighting, appliance, tool, and motor
loads. This total should not be greater than the gen-
erator’s rated wattage capacity.
If the engine does not start after it has been
!
cranking for 15 seconds, release the Start/Stop
switch, wait 15 seconds, and try again. Holding
the switch for longer than 15 seconds can
damage the starter motor.
• Most lighting, appliance, tool, and motor loads
indicate their required watts on their nameplate or
data plate. For light bulbs, simply note the wattage
rating of the bulb.
• If a load does not show its rated wattage, multiply
that load’s rated VOLTS times AMPS to obtain
WATTS.
4. Let the engine run at no-load for a few minutes to
stabilize and warm up.
5. Turn ON electrical loads, using the means
provided in the vehicle (such as, a main-line cir-
cuit breaker or transfer switch).
2.5 STOPPING THE GENERATOR
1. Turn OFF all electrical loads, using the means
provided in the vehicle (such as, a main-line cir-
cuit breaker or transfer switch).
• Induction-type motors (such as, those that run the
vehicle’s furnace fan, refrigerator, air conditioner,
etc.) need about 2-1/2 time more watts of power for
starting than for running (for a few seconds during
motor starting). Be sure to allow for this when con-
necting electrical loads to the generator. First, cal-
culate the watts needed to start electric motors in
the system. To that figure, add the running
wattages of other items that will be operated by the
generator.
2. Let the generator run at no-load for a few minutes,
to stabilize internal engine generator temperatures.
Do not stop the engine/generator immediately
after running under load. This can overheat
!
• For the first two or three hours of operation, do not
apply electrical loads over 75 percent of the unit’s
rating.
and damage the engine and/or generator.
3. Press and hold the Start/Stop switch in the STOP
position, until the engine shuts off.
2.7 PROTECTION SYSTEMS
2.6 APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator,
observe these guidelines:
The engine has several safety switches that cause
it to automatically shut down, under the following
conditions: low oil pressure, high coolant tempera-
ture, and engine overspeed. See Figure 2.2 for the
location of these devices. If automatic shutdown does
occur, refer to “Troubleshooting Guide”.
• Before applying electrical loads, let the generator
stabilize and warm up for a minute or two.
• DO NOT overload the generator.
2.7.1 LOW OIL PRESSURE SWITCH
◆
2.6.1 LETTING THE ENGINE STABILIZE
◆
This switch is normally closed (N.C.) but is held open
by engine oil pressure during engine running. Should
operating oil pressure drop below approximately 10
psi, the switch contacts close, and the engine shuts
down automatically.
The generator supplies correctly rated voltage only at
the proper governed speed. Some electrical appli-
ances may be extremely sensitive to voltage. Incorrect
voltages can damage such appliances.
Electrical loads applied on the engine at reduced
operating speeds, such loads imposed on the engine,
when sufficient power is not available, may shorten
engine life. Never turn ON electrical loads until after
the generator engine has started and stabilized at no-
load.
2.7.2 HIGH COOLANT TEMPERATURE SWITCH
◆
This normally-open (N.O.) thermostatic switch has a
sensing tip that is immersed in captive coolant.
Should the coolant temperature exceed approximate-
ly 115° C (240° F), the switch contacts close, and the
engine shuts down automatically.

QUIETPACT™ 75D Recreational Vehicle Generator
The voltage regulator also incorporates a “voltage

surge protection circuit.” This circuit prevents trou-
blesome surges in the generator AC output voltage.
Voltage surge is a common cause of damage to elec-
tronic equipment.
2.8 ADDITIONAL INFORMATION
2.8.1 25-HOUR BREAK-IN PERIOD
◆
The first 25 hours of operation is the break-in period
for the generator. Properly breaking in the generator
is essential to minimize oil consumption and maxi-
mize engine performance. During this 25-hour
break-in period, observe the following rules:
• Run the unit at varying electrical loads to help seat
the engine piston rings properly.
• After operating the unit for 25 hours, complete the
tasks recommended under Section 2.8.2.
• For the next 75 hours of operation, following the
break-in period, avoid light electrical loads. Load
the generator at 50 percent (or more) of its rated
wattage capacity. Repeated light loads during these
75 hours can cause improper seating of engine pis-
ton rings, resulting in blowby and high oil con-
sumption.
• Check the engine oil level frequently. Add oil if
needed. It is normal for the generator engine to
consume more oil than normally, until the piston
rings have properly seated.
2.7.3 OVERSPEED SHUTDOWN
◆
A DC control circuit board senses engine speed from
the frequency of the alternator AC output. Should the
alternator output frequency exceed approximately 72
Hertz (4,320 alternator rpm), circuit board action
initiates an automatic engine shutdown.
2.7.4 OVERVOLTAGE PROTECTION
◆
A solid-state voltage regulator (Figure 2.3) controls
the generator’s AC output voltage. This regulator sup-
plies an excitation current to the rotor. By regulating
the rotor’s excitation current, the strength of its mag-
netic field is regulated and, in turn, the voltage deliv-
ered to connected electrical loads is controlled. When
the AC frequency is 60 Hertz, voltage is regulated at
120 volts (voltage-to-frequency ratio is 2-to-1).
2.8.2 25-HOUR CHECK-UP
◆
After the 25-hour break-in period, contact a Generac
Authorized Service Dealer for the following mainte-
nance, for which the vehicle owner is responsible for
all charges:
• Change the engine crankcase oil and oil filter.
• Check all fluid levels (engine coolant, fuel,
battery electrolyte fluid).
Figure 2.3 – Solid-state Voltage Regulator
• Visually inspect the unit for any leaks or loose
hardware.
• Inspect the exhaust tailpipe for any leaks or
damage.
2.8.3 ATTENTION REQUIRED
◆
AFTER SUBMERSION
If the recreational vehicle generator has been sub-
merged in water, it MUST NOT be started and oper-
ated. Following any submersion in water, have a
Generac Authorized Service Dealer thoroughly clean
and dry the generator.

2.8.4 OPERATION IN HIGH GRASS
OR BRUSH
◆
Never operate the generator while the vehicle is
parked over high grass, weeds, brush, leaves, or
other combustible substance. Such materials can
ignite and burn from the heat of the exhaust system.

2.8.5 EFFECTS OF MOISTURE AND DIRT
◆
Keep the generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive
vapors, road splash, etc. Permitting dirt and mois-
ture to accumulate on generator windings will have
an adverse effect on the insulation resistance of those
windings.
OIL DRAIN
PLUG
LATCHES

DOOR
When moisture is allowed to remain in contact with
windings, some of the moisture will be retained in
voids and cracks in the insulation. This reduces insu-
lation resistance and will eventually cause problems.
Dirt will make the problem worse, since it tends to
hold moisture in contact with windings. Salt (as from
sea air) will also worsen the problem, since it tends
to absorb moisture from the air. Salt and moisture,
when combined, form a good electrical conductor.
3.2 CHANGING THE ENGINE OIL
AND/OR OIL FILTER
Change the engine oil and oil filter after the first 25
hours of operation (after the 25-hour break-in peri-
od, see Section 2.8.1). See the “Service Schedule,”
Section 3.13, for subsequent oil and filter changes.
Change the oil more frequently, if operating consis-
tently under heavy load or at high ambient tempera-
tures.
3.1 CHECKING THE ENGINE OIL
LEVEL
After the 25-hour break-in period, check the engine
crankcase oil level every eight hours of operation, or
at least once daily, before using the generator. For oil
capacities and requirements, see “Engine Oil
Requirements,” Section 1.5.3. To check the engine oil
level, proceed as follows (see Figure 3.1):
To change the oil and/or oil filter, proceed as
follows (see Figure 3.1):
1. Run the engine until it is thoroughly warmed up
(for at least five minutes) then shut OFF
the engine.
2. Immediately after the engine shuts OFF, remove
the front service door, located beneath the unit,
by retracting the two latches and pivoting the
door downward.
3. Remove the air filter (see Section 3.3).
4. Remove the oil-drain plug and drain the oil into a
suitable container. Removing the oil-fill plug will
allow the crankcase to drain faster.
1. Be sure the generator is as leveled as possible.
2. Remove the dipstick, and wipe it dry with a clean,
lint-free cloth.
3. Install the dipstick, and fully seat the T-handle;
then, remove it again. The oil level should be at
the dipstick “Full” mark.
4. If necessary, remove the oil fill plug and slowly
add oil until it reaches the dipstick “FULL” mark.
DO NOT FILL ABOVE THE “FULL” MARK.
5. After the oil has drained, replace the oil-drain
plug.
Go to step 9 if changing oil only.
Never operate the engine with the oil level
below the “ADD” mark on the dipstick. Doing
this could damage the engine.
6. With the oil drained, remove the old oil filter by
!
turning it counterclockwise.
7. Apply a light coating of clean engine oil to the gas-
ket of the new filter.
8. Screw the new filter on by hand, until its gasket
lightly contacts the oil filter adapter. Then, tight-
en the filter an additional 3/4 to one turn.
5. Install the oil-fill plug and the dipstick before
operating the engine.

The exhaust system of this product gets
extremely hot and remains hot after shutdown.
High grass, weeds, brush, leaves, etc., must
remain clear of the exhaust. Such materials may
ignite and burn from the heat of the exhaust
system.
Failure to provide and maintain a spark arrestor
may be in violation of the law. If this generator
!
is used on any forest-covered, brush-covered,
or grass-covered unimproved land, the vehicle
owner or operator must maintain the spark
arrestor in good condition. In the state of
California, the preceding is required by law
(Section 4442 of the California Public Resources
Code). Other states may have similar laws.
Federal laws apply on federal lands.

3.6 BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in use.
Be sure to reinstall the hex pipe cap tightly to
The generator battery should be inspected per the
“Service Schedule,” Section 3.13. The following pro-
cedure should be used for inspection:
the spark arrestor cleanout pipe. Vibration
could cause a loose cap to fall out, resulting in
hot engine exhaust being drawn through the
centrifugal cooling fan and out beneath the
unit. This could result in damage to the genera-
tor or in discharge of hot exhaust sparks
beneath the unit.
• Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
• Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.
• Have the state of charge and condition checked by
Figure 3.3 – Spark Arrestor

NOTE:
Servicing of the battery is to be performed or
supervised by knowledgeable personnel, accord-
ing to the required precautions. Keep unautho-
rized personnel away from batteries.
3/8" NPT HEX
PIPE CAP
Damage will result if the battery connections are
made in reverse.
DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding. Storage batter-
ies release explosive hydrogen gas. This gas can
form an explosive mixture around the battery
for several hours after charging. The slightest
spark can ignite the gas and cause an explo-
sion. Such an explosion can shatter the battery
and cause blindness or other injury. Any area
that houses a storage battery must be properly
ventilated. Do not allow smoking, open flame,
sparks, or any spark-producing tool or equip-
ment near the battery. Discharge static electrici-
ty from body before touching the battery by
first touching a grounded metal surface.

ACCESS PLATE
3.5 CLEANING THE GENERATOR
Keep the generator as clean and as dry as possible.
Dirt and moisture that accumulate on internal gener-
ator windings have adversely affect insulation resis-
tance.
Periodically, clean the generator’s exterior surfaces.
A soft brush may be used to loosen caked-on dirt.
Use a vacuum system or dry, low-pressure air to
remove any accumulations of dirt. The generator is
housed inside an all-weather enclosure; clean the
enclosure with a soft, damp cloth or with sponge and
water.
A battery presents a risk of electrical shock and
high short-circuit current. The following precau-
tions are to be observed when working on bat-
teries:
Once each year, have the generator cleaned and
inspected by a Generac Authorized Service Dealer.
Service technicians will use dry, low-pressure air to
clean internal windings. Parts inside the control con-
sole should be cleaned and inspected at this time, as
well.
• Remove watches, rings, and other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery;
• Disconnect any charging source prior to connect-
ing, or disconnecting, battery terminals; and
Finally, have the insulation resistance of stator and
rotor windings checked. If insulation resistances are
excessively low, the generator may require drying.
• Do not use any jumper cables or booster battery
to crank and start the generator engine. If any bat-
tery has discharged, remove it for recharging.
Do NOT use a forceful spray of water to clean
the generator. Water will enter the generator
!
interior and cause problems, and may also
contaminate the generator fuel system.

QUIETPACT™ 75D Recreational Vehicle Generator
DANGER
Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to
the skin and eyes, and to be toxic.
Do not remove the radiator pressure cap while
the engine is hot; otherwise, serious burns
from boiling liquid or steam could result.
!
!
!
!
The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive. The following
procedures are to be observed:
Ethylene glycol base antifreeze is poisonous.
Do not use mouth to siphon coolant from the
radiator, recovery bottle, or any container.
Wash hands thoroughly after handling. Never
store used antifreeze in an open container
because animals are attracted to the smell and
taste of antifreeze, even though it is poisonous
to them.
• Wear full eye protection and protective clothing;
• Immediately wash with water all skin areas that
come into contact with the electrolyte.
• If the electrolyte contacts the eyes, immediately
flush eyes thoroughly with water, and seek med-
ical attention.
• Spilled electrolyte is to be washed down with an
acid-neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) of water. The bicar-
bonate of soda solution is to be added until the
evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area dried.
Do not use any chromate base rust inhibitor
with ethylene glycol base antifreeze; other-
wise, chromium hydroxide (“green slime”) will
form and cause overheating. Engines that have
been operated with a chromate base rust
inhibitor must be chemically cleaned before
adding ethylene glycol base antifreeze. Using
any high-silicate antifreeze boosters or addi-
tives will also cause overheating. DO NOT use
any soluble oil inhibitor for this equipment.
!
3.7 COOLING SYSTEM
Air intake and outlet openings in the generator com-
partment must be open and unobstructed for contin-
ued proper operation. Avoid obstructions, such as,
high grass, weeds, brush, leaves, and snow.
3.9 MAJOR SERVICE MANUAL
To obtain a service manual for the generator, the
nearest Generac Authorized Service Dealer. Make
sure to identify the MODEL NUMBER and SERIES.
Without sufficient cooling and ventilating air flow, the
engine/generator quickly overheats, which causes it
to shut down.
3.10 DRIVE BELT
The engine drives the generator rotor by means of a
pulley and drive belt arrangement. Drive belt tension
was properly adjusted before the unit was shipped
from the factory. If suspect that drive belt tension is
incorrect, contact a Generac Authorized Service
Dealer.
3.8 ENGINE COOLANT
Check the coolant level in the coolant recovery tank
at least once daily or prior to use. Add the recom-
mended coolant mixture (see Section 1.5.4), as nec-
essary; the tank should be kept within the levels indi-
cated on the adjacent decal. If desired, a high-quality
rust inhibitor to the recommended 50-50 coolant
mixture may be added. If added consistently, the rec-
ommended mixture will protect the unit against
freezing temperatures.
3.11 EXERCISING THE GENERATOR
At least once every seven days, start and operate the
generator. Let the unit run for at least 30 minutes to
“exercise” the engine. If the generator cannot be exer-
cised every seven days, and it is to be out of service
longer than 30 days, see Section 3.12.
Periodically remove the radiator pressure cap, locat-
ed behind the access cover above the user control
panel, to make sure the coolant recovery system is
functioning properly. Coolant should be at the bottom
of the radiator filler neck. If the coolant level is low,
inspect the gasket in the radiator pressure cap.
Replace the cap, if necessary. To have the pressure
cap tested, contact a Generac Authorized Service
Dealer. Inspect both the cooling system and coolant
recovery system for leaks.

!
GENERAL HAZARDS
These Installation Instructions have been published
by Generac to aid in the installation of the products
described in this manual. Generac assumes that
installation personnel are familiar with the procedures
for installing such products, or similar products that
Generac manufactures. Generac also assumes that
personnel have been trained in the recommended
installation procedures for these products and that
such training includes (a) use of common hand tools,
(b) use of special Generac tools, and (c) use of any
tools and/or equipment from other suppliers.
• For safety reasons, Generac recommends that the
installation, initial startup, and maintenance of
this equipment is carried out by a Generac
Authorized Service Dealer.
• The engine exhaust fumes contain carbon monox-
ide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust sys-
tem must be installed properly, in strict compli-
ance with applicable codes and standards.
Following installation, do nothing that might ren-
der the system unsafe or in noncompliance with
such codes and standards. The generator com-
partment must be completely vapor-sealed from
the vehicle interior. There must be no possibility of
exhaust fumes entering the vehicle interior. Never
operate this equipment with a leaking or defective
exhaust system.
Generac cannot possibly know of, nor advise the
recreational vehicle trade of, all conceivable methods,
procedures, or techniques by which to perform an
installation. Nor can Generac anticipate every possi-
ble hazard that might result from each installation
method, procedure, or technique. Generac has not
undertaken any such wide evaluation. Therefore,
people who use a method, procedure, or technique
that Generac does not specifically recommend must
first completely satisfy themselves that their safety,
the safety of the vehicle's occupants, and the prod-
uct's safety are not endangered by the method, pro-
cedure, or technique selected.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts.
Never remove any drive belt or fan guard while
the unit is operating.
• Adequate, unobstructed flow of cooling and ven-
tilating air is critical to correct generator oper-
ation and is required to expel toxic fumes and
fuel vapors from the generator compartment.
Without sufficient cooling airflow, the
engine/generator quickly overheats, which caus-
es serious damage to the generator. Do not alter
the installation or permit even partial blockage
of ventilation provisions, as this can seriously
affect safe operation of the generator.
• When working on this equipment, remain alert at
all times. Never work on the equipment when
physically or mentally fatigued.
• Before performing any maintenance on the genera-
tor, disconnect its battery cables to prevent acci-
dental startup. First, disconnect the cable from the
battery post, indicated by a NEGATIVE, NEG, or
(–). Reconnect that cable last.
• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating con-
ditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
• Never insert any tool or other object through open-
ings in the generator interior, even if the unit is not
running. Serious injury or damage to the equip-
ment could be done.
Information, illustrations, specifications, etc., con-
tained in these Installation Instructions are based on
the latest information available at the time of publi-
cation. Every effort has been expended to be sure that
such data are both accurate and current. However,
the manufacturer reserves the right to change, alter,
or otherwise improve this product at any time, with-
out prior notice.
DANGER
Despite the safe design of this generator,
operating this equipment imprudently, neglecting
!
its maintenance, or being careless can cause
possible injury or death. Permit only responsible
and capable persons to operate or maintain this
equipment.
Parts of the generator are rotating and/or hot
during operation. Exercise care near running
!
generators.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.

QUIETPACT™ 75D Recreational Vehicle Generator
ELECTRICAL HAZARDS
FIRE HAZARDS
• The generator covered by this manual produces
dangerous electrical voltages that can cause fatal
electrical shock. Avoid contact with bare wires, ter-
minals, connections, etc., while the unit is running.
Ensure all appropriate covers, guards, and barri-
ers are in place before operating the generator. If
work must be done around an operating unit,
stand on an insulated, dry surface to reduce shock
hazard.
• Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands
or feet are wet. DANGEROUS ELECTRICAL
SHOCK MAY RESULT.
• During installation onto the vehicle, properly
ground (bond) the generator either by solid mount-
ing to the vehicle frame or chassis, or by means of
an approved bonding conductor. DO NOT connect
the bonding conductor to any generator part that
might be removed or disassembled during routine
maintenance. If the grounding conductor must be
replaced, use only a flexible conductor that is of
No. 8 American Wire Gauge (AWG) copper wire
minimum.
• For fire safety, the generator must be installed
and maintained properly. Installation always
must comply with applicable codes, standards,
laws, and regulations. Adhere strictly to local,
state and national electrical and building codes.
Comply with regulations the Occupational Safety
and Health Administration (OSHA) has estab-
lished. Also, ensure that the generator is
installed in accordance with the manufacturer’s
instructions and recommendations. Following
proper installation, do nothing that might alter a
safe installation and render the unit in noncom-
pliance with the aforementioned codes, stan-
dards, laws, and regulations.
• Keep a fire extinguisher in the vehicle at all times.
Extinguishers rated “ABC” by the National Fire
Protection Association are appropriate for use on
the recreational vehicle generator electrical system.
Keep the extinguisher properly charged, and be
familiar with its use. If there are any questions per-
taining to fire extinguishers, consult the local fire
department.
• If the vehicle electrical circuits can be powered by
any other source of electricity (such as, a “dockside”
power receptacle), there must be no possibility of
connecting the different power sources to the vehi-
cle’s circuits at the same time. The dockside (utility)
power source must be positively isolated from the
vehicle’s circuits whenever the generator is operat-
ing. Failure to isolate the vehicle’s circuits from the
dockside power supply when the generator is run-
ning may result in damage to the generator or in
serious injury or death to dockside (utility) power
workers due to backfeed of electrical energy.
• In case of an accident caused by electric shock,
immediately shut down the source of electrical
power. If this is not possible, attempt to free the
victim from the live conductor. AVOID DIRECT
CONTACT WITH THE VICTIM. Use a noncon-
ducting implement, such as, a rope or board, to
free the victim from the live conductor. If the vic-
tim is unconscious, apply first aid, and get
immediate medical help.
EXPLOSION HAZARDS
• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no com-
bustible materials are left in the generator com-
partment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surround-
ing the generator clean and free from debris.
• All fuel types are potentially FLAMMABLE and/or
EXPLOSIVE and should be handled with care.
Comply with all laws regulating the storage and han-
dling of fuels.
• Fuel supply lines must be properly installed, purged
and leak-tested according to applicable fuel-gas
codes, before placing this equipment into service.
There must be no possibility of fuel vapors enter-
ing the vehicle interior.
• It is required that an approved, flexible, noncon-
ductive fuel line between the generator fuel con-
nection point and the rigid fuel lines be installed.
• Never wear jewelry when working on this equip-
ment. Jewelry can conduct electricity, resulting in
electric shock, or may get caught in moving com-
ponents, causing injury.

especially for the purpose of familiarizing installers
and owners of the applicable equipment with the
product's installation requirements. Give serious
consideration to all information and instructions in
the manual, both for safety and for continued reliable
operation of the equipment.
1.4 EQUIPMENT DESCRIPTION
Instructions and information in this section pertain to
Generac liquid-cooled generators, designed specifically
for installing in recreational vehicles. The QUIETPACT
75D operates 120/240-volt, single-phase, 60-Hertz, AC
electrical loads that require up to 62.5 amps at 120
volts or 31.2 amps at 240 volts.
Because of the different recreational vehicle models
and the variations between the models, it would be
extremely difficult, if not impractical, to provide
detailed instructions for every possible installation.
For that reason, instructions and illustrations in this
manual are general in nature. Illustrations are not
intended to serve as detailed installation blueprints.
1.5 GENERATOR ENGINE
OPERATING SPEED
The generator’s two-pole revolving field (rotor) is dri-
ven by a three-cylinder, 1.0-liter diesel engine. The
generator supplies 120/240 volts AC at 60 Hertz,
when the rotor is operating at 3,600 rpm. Engine
speed is held nearly constant by a mechanical, fixed
speed governor at 1,950 rpm.
The installation should comply strictly with all
applicable codes, standards, and regulations pertain-
ing to the installation and use of this product. If any
portion of this manual appears to be in conflict with
such codes, standards, or regulations, the applicable
codes, standards, or regulations must take prece-
dence over the manual.
1.6 GENERATOR AC
CONNECTION SYSTEM
The generator is equipped with dual stator power
windings, as shown in Figure 1.1.

QUIETPACT™ 75D Recreational Vehicle Generator
• Whether the generator is mounted above the hori-
2.1 LOCATION AND SUPPORT
zontal support tubing or suspended below the tub-
ing, the supporting frame used must be structural-
ly sound.
2.1.1 GENERATOR LOCATION
◆
The most desirable location for the generator set is
between the vehicle's main frame members.
• If the generator cannot be bolted directly to
the supporting frame or support tubing, consider
using
additional
tubing,
angle
brackets
Many recreational vehicles have been factory-
equipped with an area for the generator set. Some
may even have a generator compartment provided by
the vehicle manufacturer.
or other supports to give the supporting frame suf-
ficient strength.
2.1.3 SUSPENDED MOUNTING
◆
Plan the generator location based on the following:
If the generator will be suspended below the horizon-
tal support tubing, the suspension method used with
the vehicle frame members must (a) be able to sup-
port the weight of the generator AND (b) provide suf-
ficient restraint for the generator. One typical sus-
pended mounting system is shown in Figure 2.1. The
location of a suspended mounting system must be
carefully planned, keeping the following general rules
in mind:
• The generator set must be installed on a frame-
work that is part of the recreational vehicle, as out-
lined in Section 2.1.2.
• The location must provide an access opening that
is large enough to permit generator removal
(unless the generator is to be removed from under-
neath the supporting framework).
• The location must provide easy access to frequent-
ly serviced components, such as, filters, oil drains,
and other common maintenance parts.
• The location must provide sufficient room to
allow minimum clearances for air circulation. If
sound insulation is to be used on the compart-
ment walls and ceiling, the minimum recom-
mended clearance applies to the space between
the generator and such insulation.
• Protect the generator against road splash and debris.
Baffles or splash guards may be required to protect
certain areas of the generator. To make sure the gen-
erator is adequately protected, road-test the installa-
tion through mud, water, and slush.
Figure 2.1 – Typical Suspended Mounting System
• The location must provide adequate cooling and
ventilating airflow for the generator, without a great
deal of work and expense.
2.1.2 GENERATOR SUPPORT
◆
The generator must be securely attached to a metal
framework that has been affixed to the vehicle frame
structure by bolting or welding. The metal framework
on which the generator will rest, and which will restrain
the generator set, should consist of at least two hori-
zontal beams. These beams should consist of (a) 1-1/2-
inch square, 11-gauge steel tubing OR (b) 1-1/2-inch,
11-gauge angle iron.
The generator can be installed so that it sits on top of
the horizontal support tubing, if the vehicle design
permits. Another method is to suspend the generator
below the horizontal support tubing by means of suit-
able, structurally-sound metal framework. The fol-
lowing general rules apply:
• The installer must make certain that the selected
location will permit adequate cooling and ventilat-
ing airflow.
• Vehicle construction MUST be capable of support-
ing the weight of the generator.

Figure 2.3 – Typical Compartment Construction
2.1.4 GENERATOR RESTRAINT
◆
Use four 3/8"-16 hardened steel bolts (Grade 5) to fas-
ten the generator to the supporting frame or the sup-
port tubing. These bolts must pass through (a) the gen-
erator mounting base, (b) the compartment floor (if a
compartment is used), and (c) the supporting frame-
work (Figure 2.2). All bolts must be long enough so
that, when tight, they engage at least 3/8” of an inch [9.5
millimeters]. Refer to Section 2.2 for the location of the
generator mounting holes.
Figure 2.2 – Typical Generator Restraint
• If constructing a compartment, line the exterior
(underside) of the compartment floor with 26-
gauge galvanized steel.
• All seams, splices, and joints of the compartment
walls (unless vapor-tight by design) should
be caulked to prevent poisonous, flammable, or
explosive vapors from entering the vehicle interior.
NOTE:
2.2 GENERATOR COMPARTMENTS
Whether the generator set is being installed inside a
compartment specifically manufactured to house a
generator or inside a compartment that the installer
constructs, the compartment must meet certain spec-
ifications, as outlined in the following sections:
Caulking must be done so that the caulking mate-
rial will stay in place permanently. Pressing mate-
rials such as, putty tape, onto joints and seams is
NOT acceptable. A high-quality silicone rubber
base sealant is recommended.
2.2.1 COMPARTMENT CONSTRUCTION
◆
• Holes and openings made in the compartment
walls to allow for the passage of electrical conduit,
conductors, hoses, cables, etc., into the vehicle liv-
ing area must be sealed vapor-tight with silicone
rubber base sealant.
• If a flexible metal conduit is used, it must be sealed
internally at the end, where it terminates inside the
compartment’s electrical junction box.
NOTE:
• The generator compartment should be either con-
structed of, or lined with, 26-gauge galvanized
steel.
NOTE:
Aluminum is NOT an acceptable alternative
to galvanized steel due to aluminum’s low
melting point.
• If the compartment is lined with galvanized steel, it
may be constructed of any material. Generac rec-
ommends that the compartment be constructed of
1/2-inch thick plywood (not strandboard), with the
floor made of a double thickness of 1/2-inch ply-
wood, having the grain of the wood at cross section
for added strength (Figure 2.3).
Flexible metal conduit, due to its unique con-
struction, is NOT vapor-tight along its entire
length.

Section 2 – Installation
QUIETPACT™ 75D Recreational Vehicle Generator
• Seams and joints of the galvanized steel (whether
DANGER
used as a liner or for the compartment itself) must
be lapped and mechanically secured. Such seams
may be manufactured, welded, bolted, riveted, or
screwed. Manufactured lock seams are shown in
Figure 2.4. Installer-constructed compartments
typically utilize a standard lap joint.
Do not install sound insulation or any
absorbent material on the compartment floor
interior. Such materials will become soaked
with combustible or explosive vapors and
liquids and will become a fire hazard.
Using a combination of sound-insulating materials
can often reduce noise more effectively than a single
material. For example, a sheet of lead or visco-elastic
material, along with a layer of other acoustical mate-
rial, is more effective than when a single material is
used.
Figure 2.4 – Types of Lock Seams
2.2.3 ACOUSTICS
◆
For additional noise abatement, the installer may
wish to consider the following:
• Using special sound-insulating materials.
• Construction of a special noise abatement
compartment.
NOTE:
• After the compartment has been metal -lined and
vapor-sealed, line the compartment interior walls
and ceiling with an approved, nonflammable
sound-insulating material. See Section 2.2.2.
Any method used to reduce noise must not
adversely affect the flow of cooling and ventilating
air into, or out of, the compartment.
In addition to the effective use of sound insulating
materials, construction of a special noise abatement
compartment might be considered to reduce noise
levels. Such a compartment might be constructed as
follows (Figure 2.5):
DANGER
Do not install any flammable material directly
above or around the compartment. Heat, trans-
ferred through the compartment structure, may
be sufficient to ignite, char, or discolor seat
cushions, fiberboard, and other flammable
materials. Use approved, nonflammable insulat-
ing materials in high temperature areas.
• Use 5/8-inch thick or 3/4-inch thick plywood in the
compartment.
• Construct the compartment floor of a double thick-
ness of 5/8-inch or 3/4-inch plywood.
• Line the compartment’s interior walls and floor, as
well as the underside of the floor, with 26-gauge
galvanized steel.
2.2.2 SOUND INSULATING MATERIALS
◆
Once installers have determined that a compartment
is properly constructed and metal-lined, they can add
acoustical material. This may include additional
sealant or insulating material, to reflect noise away
from the vehicle interior.
• Vapor-seal all compartment seams and joints.
• Over the galvanized steel lining, install a combina-
tion of acoustical materials, as mentioned in
Section 2.2.2.
DANGER
Sound insulating materials should be of a nonflam-
mable type. One excellent insulating material is a 1-
inch (25 mm) thick fiberglass having a 2-pound den-
sity. When fiberglass is used, its coated side should
face toward the compartment interior.
To prevent fire or explosion, do not install any
insulation, or other absorbent materials, on the
interior or underside of the compartment floor.
• Seal all compartment door edges to prevent noise
leakage around the door perimeter.
• Line the compartment door interior (except for air
openings) with suitable, fireproof sound insulation
(such as, 1-inch (25 mm) thick fiberglass with a 2-
pound density).

QUIETPACT™ 75D Recreational Vehicle Generator
2.3.2 COOLING AIR INLET OPENINGS
◆
2.3 COOLING AND VENTILATING AIR
It is absolutely essential that an adequate flow of air
for cooling, ventilation, and engine combustion be
supplied to the generator set. Without sufficient air-
flow, the engine/generator quickly overheats. Such
overheating can cause serious operating difficulties
and also may cause fire and personal injury. The
installer must make sure that sufficient air is avail-
able to the generator for cooling, ventilating, and
combustion. The installer also must provide a path
for exhausting the cooling air to the exterior of a com-
partment, if so equipped.
The minimum size of the air inlet opening, whether
the generator is housed in a conventional compart-
ment or not, is at least 150 square inches
2
(975 cm ) (see Figure 2.8). This rule applies whether
inlet air is brought in through an opening in the com-
partment door, an opening in the vehicle skirt,
through ductwork, or by any other means.
NOTE:
Screening, louvers, or expanded metal that cover
air openings restrict airflow. Compensate for this
by making the actual air opening proportionately
larger. See Section 2.3.3.
DANGER
Never use discharged cooling air for heating or
permit such air to enter the vehicle interior. This
air contains deadly carbon monoxide gas and
other poisonous, flammable, or explosive gases.
Figure 2.8 – Air Inlet in Compartment Door
2.3.1 GENERATOR AIRFLOW
◆
This unit uses an impellar fan located on the alterna-
tor drive pulley to cool the alternator’s internal com-
ponents. Air is drawn through the alternator and
expelled radially behind the drive pulley. An engine-
driven centrifugal blower draws in cooling air
through air inlet openings, moves that air around the
engine/generator and across the radiator, then dis-
charges that air out the bottom (see Figure 2.7).
Figure 2.7 – Airflow Through Engine/Generator
When the unit is installed on a suspended mounting
system, one of several different methods of supplying
airflow may be used as follows:
• Provide a door in the vehicle skirt having an air
inlet opening (Figure 2.9).
Figure 2.9 – Suspended Mount: Inlet Door
• Use ductwork (Figure 2.10). The installer must be
sure air is available to the sides of the generator for
proper air intake.
• Provide an opening in the vehicle skirt and space
around the generator for cooling airflow (Figure
2.11). Recommended clearance around all sides of
the generator is at least two inches (50 mm).

2.3.4 TESTING THE INSTALLATION
◆
Generac recommends testing the installation to be
sure adequate cooling airflow is available to the unit,
before placing the unit into service. If the unit shows
signs of overheating, enlarge the air openings. Never
place a unit into service until absolutely certain that
cooling and ventilation is adequate.
NOTE:
The installation must be tested, especially if bring-
ing in air from below the generator set.
2.4 DIESEL FUEL SYSTEM
Figure 2.11 – Air Inlet in Vehicle Skirt
The installation of a diesel fuel system (Figure 2.12)
for a recreational vehicle generator set must comply
with applicable codes, standards, and regulations.
The entire fuel system must be completely free of
leaks. There must be no possibility of fuel vapors
entering the vehicle interior.
Figure 2.12 – Generator Fuel System
2.3.3 COMPENSATING FOR RESTRICTIONS
◆
Materials, such as, screening, louvers, or expanded
metal, can restrict the free flow of air. Compensate for
this restriction by making the actual air opening pro-
portionately larger.
Some materials may offer only a 60 percent “free air
inlet area.” Other more efficient materials may pro-
vide up to a 90 percent free air inlet area. The per-
centage of free air inlet opening is usually available
from the material’s supplier or manufacturer.
To determine the actual air inlet opening size
2
required, divide 150 square inches (975 cm ) by
the percentage of free air inlet area for the mater-
ial being used.
DANGER
For example: If planning to use screening with an 80
percent free air inlet area, divide 150 (975) by 0.8,
which results in 187.5 square inches (1,218.75 cm2).
Minimum actual size of air inlet opening in this case
is 187.5 square inches (1,218.75 cm2).
All fuel types are potentially FLAMMABLE
and/or EXPLOSIVE and should be handled
with care. Comply with all laws regulating the
storage and handling of fuels. Properly install
and maintain the fuel system, and keep it
entirely free of leaks. Fuel vapors must
not enter the vehicle interior.

2.4.2 GENERATOR FUEL SUPPLY LINES
2.4.2.1 Rigid Fuel Lines
Those lines used to supply fuel from a tank to the
generator must comply with applicable codes, stan-
dards, and regulations. The following general rules
apply to rigid fuel lines:
◆
gaseous fuels, they are considered safer from the
standpoint of storage and handling. As a result,
installers may tend to be careless in their installation
practices, which can result in poor engine perfor-
mance. For example, a poorly tightened fuel line may
not show any signs of leakage; however, air can be
drawn into the loose connection and cause problems.
Air that is trapped in the diesel fuel system results in
hard starting and rough engine operation.
• Rigid lines should be of annealed, seamless, drawn
aluminum, or steel.
• Lines and fittings must comply with SAE J512F,
“Standard Automotive Fittings,” or with ANSI
B126.26 (latest edition).
• Route the fuel line so that at least 2 inches (51 mm)
of clearance is maintained between the line and
any exhaust system parts.
• Do not attach electrical wiring to fuel lines. Route
the wiring so it cannot come into contact with any
fuel line.
• Route fuel lines so that, if they leak, fuel does not
drip onto any electrical or exhaust system parts.
• Use nonferrous metal straps without sharp edges
to secure fuel lines.
Dirt that enters the fuel system also may cause prob-
lems. Lines and piping must be properly installed
and tightened to prevent dirt from entering. Diesel
fuel must be kept clean.
Factory-installed generator fuel system components
include (a) a fuel filter, (b) a 12-volt DC electric pump,
(c) an injection pump, and (d) interconnecting lines
and fittings. Connect a fuel supply line to the supply
fitting and a return line from the fuel return fitting
back to the tank.
NOTE:
Fuel supply and return fittings located on the gen-
erator are 1/8” NPT.
• Fuel system components must be accessible, but
protected from abrasion, chafing, road damage,
and kinking.
Use a length of approved flexible fuel hose between
the fuel connection fittings and rigid fuel lines (see
Sections 2.4.2 and 2.4.3).
2.4.2.2 Flexible Fuel Line
Use a length of approved flexible fuel hose between
the generator fuel supply fitting and rigid fuel lines.
This prevents breaking of the line caused by vibra-
tion, shifting, settling, or movement. The following
rules apply:
2.4.1 FUEL TANK
◆
Either the generator must share the vehicle’s engine
fuel tank, or a separate fuel tank for the generator set
must be installed. All fuel tanks installed on the vehi-
cle must be constructed, installed, and restrained so
they comply with applicable codes, standards, and
regulations.
• The flexible hose must comply with SAE J30B,
“Standard for Fuel and Oil Hose.” It must be
approved for use with diesel fuel.
• The hose should be at least 6 inches (152 mm)
longer than is needed, to prevent the hose from
rupturing if the generator shifts or settles.
If the generator is to share the vehicle’s engine tank,
separate fuel pickup tubes are required for the engine
and the generator. Generac recommends that the fuel
pickup tube be two to three inches (51 to 76 mm)
shorter than the vehicle’s engine pickup tube. This
prevents the generator from depleting the entire fuel
supply during prolonged generator operating peri-
ods.
2.4.3 GENERATOR FUEL RETURN LINES
◆
The same general rules that apply to fuel supply lines
also apply to fuel return lines.
NOTE:
Locate the diesel fuel return line at least 12 inch-
es from the tank fuel pickup tubes to prevent air
bubbles from entering the fuel supply lines.
Do NOT tee the generator fuel supply line into
the vehicle engine fuel supply line. If this is
!
done, the generator will be starved of fuel
when both engines are operating at the same
time. Also, while the vehicle engine is not run-
ning, generator operation may drain the vehi-
cle engine supply line, making it difficult to
start the vehicle engine.

2.5.2 EXHAUST SYSTEM SAFETY
◆
2.5 EXHAUST SYSTEM
The generator exhaust system must be safely and
properly installed. Only approved exhaust system
parts must be used. A properly installed exhaust sys-
tem must be vapor-tight, quiet, and completely safe.
• Maintain a clearance of at least 3 inches (76 mm)
between exhaust system parts and any com-
bustible material (such as, wood, felt, cotton,
organic fibers, or other like material). If the 3-inch
(76 mm) clearance cannot be maintained, locate,
insulate, or shield the exhaust part(s) so that the
temperature of any combustible material is not
raised to more than 117° F (65° C) above the
ambient air temperature.
DANGER
The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
!
dangerous gas, if breathed in sufficient concen-
trations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOX-
IDE POISONING ARE (a) inability to think coher-
ently, (b) vomiting, (c) twitching muscles, (d)
throbbing temples, (e) dizziness, (f) headaches,
(g) weakness, and (h) sleepiness. IF FEELING
ANY OF THESE SYMPTOMS, MOVE INTO FRESH
AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET
MEDICAL HELP. Do not operate the generator
until its exhaust system has been inspected and
properly repaired.
• Terminate the exhaust tailpipe at least 3 feet (91
cm) from the vehicle’s fuel filler cap and at least
2 inches (51 mm) past the outer edge of the vehi-
cle. Do not terminate the exhaust system under
the vehicle.
• Terminate the exhaust tailpipe such that exhaust
gases will not be drawn back into the generator
compartment and recirculated.
• Fuel and oil must NOT be able to drip onto any
exhaust system part.
Figure 2.13 – Typical Exhaust System
Never tee the generator engine exhaust pipe
into the vehicle engine exhaust piping. This
!
causes excessive back pressure on the genera-
tor engine. Also, water from one engine can
damage the other engine.
2.5.1 MUFFLER AND SPARK ARRESTOR
◆
The exhaust muffler supplied with the QUIETPACT ™
75D is a spark arrestor type that meets code and
standard requirements of the U.S. Forest Service.
Any person(s) installing an unapproved muffler, or an
unapproved exhaust system part, or modifying an
exhaust system in any way that might cause a hazard,
is liable for any damage, injury, or warranty expense
that might be caused by such unapproved installation
or modification.

• If there is any possibility of the tailpipe or muffler
being damaged, protect these damage-prone areas
by means of a protective device (such as, a skid
bar).
• Install the generator exhaust system according to
safe automotive practices.
• Use enough exhaust system hangers to prevent any
part of the system from being dislocated.

partment wall.
Generac. Using unapproved exhaust mufflers and
exhaust system parts is the responsibility of the
person(s) installing such unauthorized parts.
• Do not terminate the exhaust system under any
opening, window, or vent that can be opened or is
not permanently sealed from the vehicle interior.
• Exhaust piping must be large enough to prevent
excessive back pressure on the generator engine.
• Never tee the generator engine exhaust pipe into
the vehicle engine exhaust piping. This causes
excessive back pressure on the generator engine.
Also, water from one engine can damage the other
engine.
If a flexible metal conduit is used between the gen-
erator and the compartment junction box, the con-
duit end that terminates at the compartment junc-
tion box must be vapor-sealed. Flexible metal con-
duit is NOT vapor-tight along its entire length.
• From the junction box, route power supply wires
through approved conduit to either (a) double-
pole, double-throw transfer switch, or (b)
approved isolation receptacle. Connecting to a
transfer switch or isolation receptacle must pre-
vent vehicle electrical circuits from being connect-
ed to two different power supplies at the same time
(such as, generator and dockside power).
• Plan exhaust system installation carefully. Comply
with all applicable codes, standards, and regula-
tions.

be of a larger conductor size.
The following general rules apply to electrical con-
nections in a recreational vehicle:
2.6.3 GENERATOR AC CONNECTIONS
◆
Generator AC output leads T1 (red), T2 (white), and
T3 (black) come out of the generator, as shown in
Figure 2.14. Leads T1 (red) and T3 (black) are “hot,”
while T2 (white) is the grounded neutral lead. There
is also a green lead that connects to ground in the
junction box of the recreational vehicle.
• Qualified electricians who are familiar with applic-
able codes, standards, and regulations should
install electrical wiring.
• The wiring should comply with codes, standards,
and regulations. The National Electrical Code
(NFPA 70), and state and local codes apply.
• Switches and circuit breakers should be of a type
approved for use in recreational vehicles and must
be mounted and installed to prevent damage from
road shock.
Figure 2.14 – Generator AC Output Leads
T1 (Red)
T2 Neutral (White)
• Wiring must be of adequate size, have approved
insulative qualities, and be properly supported.
• Conduit and wire openings into the generator com-
partment (if used) must be vapor-sealed to prevent
entry of flammable, explosive, or poisonous gases
into the vehicle.

2.6.1 ELECTRICAL JUNCTION BOX
◆
Install an approved, square electrical junction box
with a blank cover on the interior or exterior wall of
the area planed for installation of the generator (NOT
on the generator). Route the generator's AC output
leads into this junction box through approved flexible
conduit. This is the point of first termination for gen-
erator AC output leads.
QUIETPACT ™ generators use a four-position termi-
nal block to connect between stator power leads and
vehicle load leads. This terminal block is accessible
by removing the access panel, shown in Figure 2.14.
Units are shipped from the factory connected for
dual-voltage (120/240 volts AC) output (See Figure
2.15). The stator power windings are connected in
series. Lead 11/11A connects to T1 (Red), lead
44/44A connects to T3 (Black), while leads 22 and 33
are grounded and connect to T2 NEUTRAL (White). A
"tie bar" connects the two switch handles on line
breaker CB1.
2.6.2 WIRING
◆
• Wiring should be of stranded copper to reduce the
chance that vibration may cause breakage.
• Wire gauge size should be large enough to handle
at least 115 percent of the installed generator's
rated maximum current.
• If neutral conductors are used, they must be the
same size as other leg wires.

2.6.3.1 Generator Coversion to
120 Volts Only — Dual Circuits
NOTE:
rules apply:
• Connect 120-volt, single-phase, 60-Hertz, AC elec-
trical loads, requiring up to the trip rating of cir-
cuit breaker CB1, across AC output leads T1 (red)
and T2 (white).
• Connect 120-volt, single-phase, 60-Hertz, AC elec-
trical loads, requiring up to the trip rating of cir-
cuit breaker CB1A, across AC output leads T3
(black) and T2 (white).
• Try to keep the load balanced between the two cir-
cuit breakers and the stator windings.
• The neutral line (T2, white) on all units is a
grounded neutral.
Conversion of a QUIETPACT™ generator from
"120/240 volt dual voltage" to "120 volts only -
dual circuits" (or vice-versa) requires rerouting
wires within the unit enclosure. It is recommend-
ed that this conversion be performed by a Generac
Authorized Service Dealer.
Figure 2.16 shows the stator power winding connec-
tions for 120 volts only - dual circuits. Two stator
power windings are used, with each winding capable
of supplying half of the unit's rated wattage/amperage
capacity. The circuit from each winding is protected
against overload by a line breaker (CB1 and CB1A).
Line breakers CB1 and CB1A have a trip rating of 35
amps.
Do NOT connect electrical loads in excess of any
circuit breaker rating, or problems will develop
with circuit breaker tripping, which causes a loss
of AC output. Also, do NOT exceed the genera-
tor's rated wattage capacity. Add the watts or
amps of all lighting, appliance, tool, and motor
loads the generator will operate at one time.
This total should be less than the unit's rated
wattage/amperage capacity.
To convert from "120/240 volt dual voltage" to "120
volts only - dual circuits", disconnect battery power
from the generator and reverse stator lead wires 33
and 44 as follows:
NOTE:
It is necessary to feed stator lead wires 33 and 44
through grommets on the electrical enclosure and
engine control box in order to perform the rerout-
ing outlined below. The front and top unit enclo-
sure panels, as well as the user control panel,
must be removed to perform this. After re-routing,
wires should be properly tied down to prevent
chafing or contact with moving internal compo-
nents
Figure 2.15 – Connections for 120/240 Dual
Voltage
1. Remove stator lead wire 33, as shown in Figure
2.15, from the ground stud adjacent to the four-
position terminal block. Reroute stator lead 44
from the line side terminal of CB1 (renamed as
CB1A in Figure 2.16) to the ground stud location
previously occcupied by stator lead wire 33.
2. Move smaller gauge (#18 AWG) wire labeled #44
(not shown), from the top of CB1A to the top of
CB1. Renumber this wire #11.
Figure 2.16 – Connections for 120 Volts Only —

4. Renumber ground wire "33", located between the
four-position terminal block and ground in
Figure 2.15, as ground wire "44", as shown in
Figure 2.16.
5. Renumber wire "44A" from Figure 2.15 as wire
"33A" in Figure 2.16.
6. Connect a 12 AWG jumper wire between line
breakers CB1 and CB1A, as shown in Figure

2.6.4 CONDUIT
2.6.6 GROUND FAULT CIRCUIT INTERRUPTERS
◆
◆
Route the connections between the generator and the
junction box through approved, flexible conduit. The
following general rules apply:
The National Electrical Code (NFPA 70, 551-7)
requires that ground-fault circuit interrupters
(GFCIs) be installed on all external and some internal
electrical receptacles. Contact the manufacturer or
dealer for recommendations.
• All wiring, conduit, and interconnections must be
installed in compliance with applicable codes,
standards, and regulations.
2.6.7 ISOLATING DIFFERENT POWER SOURCES
◆
• Cut wiring to the required length, and allow extra
Connections from the junction box must terminate in
a double-pole, double-throw transfer switch (Figure
2.17). An alternate method for isolating different
power sources includes using an isolating receptacle
(Figure 2.18). Whichever method is used, be certain
that both power sources are NOT connected at the
same time.
wire for junction box connections.
• Carefully prepare conduit ends to prevent sharp
edges from cutting through wiring insulation.
• Route conduit so it does not interfere with genera-
tor movement.
• If using metallic conduit, vapor-seal the end of the
conduit where it enters the junction box. Do this
because flexible metallic conduit is not vaporproof
along its entire length.
DANGER
If the vehicle’s electrical circuits can be powered
by any other source of electricity (such as, a
“dockside” power receptacle), there must be no
possibility of connecting the different power
sources to the vehicle’s circuits at the same
time. The dockside (utility) power source must
be positively isolated from the vehicle’s circuits
whenever the generator is operating. Failure to
isolate the vehicle’s circuits from the dockside
power supply when the generator is running
may result in damage to the generator or in
serious injury or death to dockside (utility)
power workers due to backfeed of electrical
energy. Installation and connection of the gen-
erator must comply with NFPA 70, Article 551,
and NFPA 1192 (latest editions).
• All openings in the generator compartment for the
passage of wiring and conduit must be sealed and
made vapor-tight.
NOTE:
Use a high-quality silicone rubber base sealant or
other approved method (such as, explosion-proof
fittings) to seal such openings.
2.6.5 POWER SUPPLY CORD
◆
The power supply cord must comply with all applic-
able codes, standards, and regulations. It must be
large enough to handle the full amperage to which it
will be subjected.

2.19).
NOTE:
• The battery must be a 12-volt, automotive-type
storage battery.
• Use a battery with minimum ratings of 70 amp-
hours and 360 cold-cranking amps.
NOTE:
Check to be sure the cable boot for the positive
cable has been installed.
2. Connect the battery cable from the battery post,
indicated by a NEGATIVE, NEG, or (-), to the
vehicle frame ground connection (Figure 2.19).
3. Connect a cable from the vehicle frame ground to
the negative post on the generator frame.
4. Connect cables so the connectors are clean
and tight.
If the battery is to be used to power other vehicle
accessories, as well as to start the generator, a bat-
tery with a larger capacity may be necessary.
2.7.2 BATTERY CABLES
◆
Using battery cables that are too long or too small in
diameter may cause a drop in voltage, which causes
starting problems. For the best cold weather starting,
the voltage drop between battery terminals and the
generator connection point should not exceed 0.12
volts per 100 amps of cranking current.
Figure 2.19 – Connecting Battery Cables
The QUIETPACT™ 75D generator is rated at about
160 DC amps of cranking current to operate the

flush eyes thoroughly with water, and seek med-
ical attention.
2.7.4 BATTERY COMPARTMENT
Install the generator battery in its own, vented com-
partment. Place the battery compartment away from
any source of heat, sparks, or flame.
◆
• Spilled electrolyte is to be washed down with an
acid-neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) of water. The bicar-
bonate of soda solution is to be added until the
evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area dried.
Provide ventilation openings in the battery compart-
ment. The minimum size of openings should be 2
square inches at the top of the compartment. Mount
the battery on a strong, rigid supporting structure,
where leaks and spills of battery fluid will not cause
damage.

2.8 OPTIONAL ACCESSORIES
A plug-in connector (Figure 2.20) is provided on the
generator set, below the control panel. Use this to
connect an optional remote-mounted start/stop panel
to the generator. Installation of such a panel will per-
mits starting and stopping the generator engine from
any convenient location inside the vehicle.
Do not dispose of the battery in a fire. The
battery is capable of exploding. Storage batter-
ies give off explosive hydrogen gas. This gas
can form an explosive mixture around the bat-
tery for several hours after charging. The
slightest spark can ignite the gas and cause an
explosion. Such an explosion can shatter the
battery and cause blindness or other injury.
Any area that houses a storage battery must be
properly ventilated. Do not allow smoking,
open flame, sparks, or any spark-producing tool
or equipment near the battery. Discharge static
electricity from body before touching the bat-
tery by first touching a grounded metal surface.

Section 3 – Post-installation Start-up Checks
QUIETPACT™ 75D Recreational Vehicle Generator
CHECKS
5. When all tests and adjustments at no-load are
completed, apply electrical loads and check for
proper operation under load. See Section 3.4.
Run the unit at least 30 minutes, with loads
applied.
3.1 POST INSTALLATION TESTS
The generator set was factory-tested and adjusted. It
is not necessary to adjust the unit any further, except
under special circumstances.
6. Turn off all electrical loads by setting the genera-
tor’s line breakers to their “OFF” (or open) posi-
tion.
7. Let the unit run at no-load for a few minutes to
stabilize internal engine/generator temperatures.
Then, shut down the engine.
Do not make any unnecessary adjustments.
Factory settings are correct for most applica-
tions. When making adjustments, however, be
careful to avoid overspeeding the engine.
!
3.2 BEFORE INITIAL STARTUP
Before starting, complete the following:
The generator set was thoroughly tested and
adjusted at the factory before shipping. No
additional adjustment should be necessary.
Only trained, qualified service technicians
should perform adjustments outlined in this
manual.
!
1. Check the engine crankcase oil level and, if nec-
essary, fill to the dipstick “FULL” mark (cross-
hatched area) with the recommended oil. Do not
fill above the FULL mark.
2. Check the fuel supply. Fuel lines must have been
properly purged and leak-tested in accordance
with applicable fuel codes. All fuel shutoff valves
in the fuel supply lines must be open.
3.4 TESTING UNDER LOAD
Apply electrical loads equal to about 50 to 75 percent
of the unit's rated wattage/amperage capacity.
3.3 INITIAL START
Let the unit run at least 30 minutes with load
applied. During this part of the test, check that the
unit is not running excessively hot and that adequate
cooling airflow is available. Do not allow the unit to
overheat during prolonged operation.
When absolutely certain that the unit has been prop-
erly installed and prepared for use, start the engine
as follows:
1. Turn off all electrical loads. Do this by setting the
generator’s line breakers to their “OFF” (or open)
position.
2. Refer to Part I, Section 2.4, “Starting the
Generator”, for cranking and starting instruc-
tions. The engine may require more cranking for
initial starting, since the fuel lines have to be
primed (use of the preheat switch will operate the
generator’s electrical fuel pump and shorten this
time).
NOTE:
The generator engine is equipped with a high
coolant temperature switch. The switch has nor-
mally open (N.O.) contacts. When the engine
coolant temperature is too high, switch contacts
close, and the engine shuts down automatically.
GENERAC RECOMMENDS THAT THE GENERA-
TOR BE TESTED FOR ADEQUATE COOLING.
3. Let the engine warm up for about five minutes to
allow internal temperatures to stabilize.
4. Carefully inspect the engine/generator for fuel,
oil, and exhaust system leaks. Before proceeding
to the next step, correct any leakage immediately.

Appendix 6 – Warranty
QUIETPACT™ 75D Recreational Vehicle Generator
FEDERAL AND CALIFORNIA EMISSIONS CONTROL WARRANTY STATEMENT
(for non-road Diesel engines rated under 19 kW)
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), Generac Power Systems, Inc.
(GENERAC), and the engine manufacturer for this equipment, Ishikawajima Shibaura Machinery Co., Ltd. (ISM), are
pleased to explain the federal and California emission control system warranty on your engine.
In California, new 2000 and later small non-road engines must be designed, built, and equipped to meet the state's strin-
gent anti-smog standards. In other states, new 2000 and later non-road diesel engines rated under 19 kW must be designed,
built, and equipped to conform to applicable EPA regulations.
ISM must warrant the emission control system on your engine for that period of time listed below, provided there has been
no abuse, neglect, or improper maintenance of your small non-road diesel engine.
Your California and EPA emission control system may include parts, such as, the fuel injection system and other emission-
related assemblies.
Where a warrantable condition exists, GENERAC will repair your engine at no cost to you, including diagnosis, parts, and labor,
on behalf of ISM. Although ISM is ultimately responsible for this warranty, GENERAC has agreed to carry out ISM's warranty
repair responsibilities, and GENERAC should be your primary contact for emission-related warranty service.
MANUFACTURER'S WARRANTY COVERAGE
For 2000 and later small non-road diesel engines, first sold in California, and for 2000 and later non-road diesel engines
rated under 19 kW, first sold in all other states, the applicable warranty period is two (2) years or 1,500 hours, whichever comes
first.
If any emission-related part on your engine is defective, the part will be repaired or replaced by a Generac Authorized
Warranty Service Facility on behalf of ISM.
PARTS COVERED
This emission control system warranty applies to the following engine emission control parts.
• Fuel Injection Pump
• Intake Manifold
• Air Cleaner Element
• Fuel Injectors
• Exhaust Manifold
• Miscellaneous Hoses, Bolts and Connectors
OWNER'S WARRANTY RESPONSIBILITIES
As the engine owner, you are responsible for the performance of the required maintenance listed in your Owner's Manual.
GENERAC and ISM recommend that you retain the original purchase documentation and all receipts covering maintenance
on your engine, but GENERAC and ISM cannot deny warranty solely for the lack of receipts or for your failure to ensure the
performance of all scheduled maintenance.
As the engine owner, you should be aware, however, that GENERAC and ISM may deny you warranty coverage if your engine
or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications.
You are responsible for contacting a Generac Authorized Warranty Service Facility as soon as a problem occurs. The
warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
Warranty Service can be arranged by contacting either your selling dealer or a Generac Authorized Warranty Service Facility.
To locate the Generac Authorized Warranty Service Facility nearest you, call our toll-free number:
1-800-333-1322
If you have any questions regarding your warranty rights and responsibilities, you should contact GENERAC at the
following address:

Appendix 6 – Warranty
QUIETPACT™ 75D Recreational Vehicle Generator
OBLIGATIONS AND RIGHTS OF THE MANUFACTURER AND OWNER
The new model year, class of diesel engine, and emission application determination for your engine are identified on the
emission control information label affixed to the right-hand side of your engine's timing gear case. The warranty period
begins on the date the new equipment is sold to the first retail purchaser.
Any emission control system parts scheduled for regular inspection that are proven defective during normal use will be
repaired or replaced during the warranty period. Any warranted part that is scheduled for replacement, and that fails prior
to replacement, will be repaired or replaced under warranty, and the repaired or replaced part will be covered under war-
ranty for the remainder of the period prior to the first scheduled replacement. The warranty repairs and service will be per-
formed by any Generac Authorized Warranty Service Facility, with no charge for parts or labor (including diagnosis).
As the engine owner, you are responsible to perform all the required maintenance listed in your Owner's Manual. GEN-
ERAC will not deny an emission warranty claim solely because you have no record of maintenance; however, a claim
may be denied if your failure to perform maintenance resulted in the failure of a warranted part. Receipts covering reg-
ular maintenance should be retained in the event of questions, and these receipts should be passed on to each subse-
quent owner of the engine.
It is recommended that replacement parts used for maintenance or repairs be GENERAC authorized and approved parts,
to maintain the quality originally designed into your emission-certified engine. However, any replacement part may be used
in the performance of any warranty maintenance or repairs and must be provided without charge to the owner. Such use
will not reduce the warranty obligations of GENERAC. Add-on or modified parts may not be used for maintenance or war-
ranty repairs. Such use will be grounds for disallowing a warranty claim, and GENERAC will not be liable to warrant fail-
ures of warranted parts caused by the use of an add-on or modified part.
LIMITATIONS
This warranty shall not cover any of the following:
(a) Systems and parts that were not first installed on the new equipment or engine as original equipment by GENERAC.
(b) Conditions resulting from tampering, misuse, abuse, improper adjustment, engine alteration, use of add-on or modified
parts, use of replacement parts that are not the same in performance and durability as GENERAC-approved replacement
parts, accident, failure to use the recommended fuel or oil, use of unapproved fuel or oil additives, or failure to perform
required maintenance.
(c) Replacement parts used for required or scheduled maintenance.
(d) Consequential damages, such as, loss of time, inconvenience, or loss of use of this engine or equipment.
(e) Damages or repair costs caused by the owner's unreasonable delay in making the engine available for inspection
and repair.
(f) Diagnosis or inspection fees that do not result in eligible warranty service being performed.
(g) Equipment with an altered or disconnected hourmeter, where the hours cannot be determined.
(h) Equipment normally operated outside the United States.
(i) Accident-caused damage, acts of nature, or other events beyond GENERAC’S control.
(j) Warranty repairs undertaken or attempted by the owner or any other person who is not affiliated with a Generac
Authorized Warranty Service Facility.
OBTAINING WARRANTY SERVICE
To obtain service under this warranty, promptly contact your nearest Generac Authorized Service Dealer or a Generac
Authorized Warranty Service Facility. If available, provide the GENERAC representative with the original purchase receipt
(showing the initial date of purchase) and all available maintenance records.

NOTE: ALL UNITS MUST BE INSTALLED BY GENERAC POWER SYSTEMS AUTHORIZED SERVICE FACILITIES. For a period
of 3 (three) years of operation from the date of original sale, Generac Power Systems, Inc. (Generac) will, at its option, repair or replace

be defective under normal use and service, in accordance with the warranty schedule set forth below. Any equipment that the pur-
chaser/owner claims to be defective must be returned to and examined by the nearest Generac Authorized Warranty Service Facility.
All transportation costs under the warranty, including return to the factory, are to be borne and prepaid by the purchaser/owner. This
warranty applies only to Generac generators sold and rated for “Recreational Vehicle” (RV) applications, as Generac has defined
Recreational Vehicle generator applications. The factory recommends exercising the unit one half-hour every month.

Generac RV generators manufactured prior to December 31, 1997, DO NOT have a transferable warranty. Generac RV generators
manufactured after January 1, 1998, have a transferable warranty to the second owner ONLY for the remainder of the three-year lim-
ited warranty. Proof-of-purchase is required and must be presented to a Generac Authorized Warranty Service Facility prior to the
performance of any warranty service.
All warranty expense allowances are subject to the conditions defined in Guardian’s Warranty Policies and Procedures Guide.
THIS WARRANTY SHALL NOT APPLY TO THE FOLLOWING:
• Generac Guardian generators that utilize non-Generac replacement parts.
• Costs of normal maintenance, adjustments, installation and start-up.
• Repairs or diagnostics performed by individuals other than Guardian/Generac authorized dealers not authorized in writing by
Generac Power Systems.
• Failures caused by any contaminated fuels, oils, coolants or lack of proper fluid amounts.
• Failures due, but not limited, to normal wear and tear, accident, misuse, abuse, negligence or improper installation. As with all
mechanical devices, the Generac engines need periodic part(s) service and replacement to perform well. This warranty will not
cover repair when normal use has exhausted the life of a part(s) or engine.
• Failures caused by any external cause or act of God, such as collision, theft, vandalism, riot or wars, nuclear holocaust, fire,
freezing, lightning, earthquake, windstorm, hail, volcanic eruption, water or flood, tornado or hurricane.
• Damage related to rodent and/or insect infestation.
• Products that are modified or altered in a manner not authorized by Generac in writing.
• Any incidental, consequential or indirect damages caused by defects in materials or workmanship, or any delay in repair or
replacement of the defective part(s).
• Failure due to misapplication.
• Telephone, cellular phone, facsimile, internet access or other communication expenses.
• Living or travel expenses of person(s) performing service, except as specifically included within the terms of a specific unit warranty
period.
• Expenses related to "customer instruction" or troubleshooting where no manufacturing defect is found.
• Rental equipment used while warranty repairs are being performed.
• Overnight freight costs for replacement part(s).
• Overtime labor.
• Starting batteries, fuses, light bulbs and engine fluids.
THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED. SPECIFICALLY, GENERAC MAKES NO
OTHER WARRANTIES AS TO THE MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Some states do not allow lim-
itations on how long an implied warranty lasts, so the above limitation may not apply to you.
GENERAC'S ONLY LIABILITY SHALL BE THE REPAIR OR REPLACEMENT OF PART(S) AS STATED ABOVE. IN NO EVENT SHALL
GENERAC BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH DAMAGES ARE A DIRECT
RESULT OF GENERAC'S NEGLIGENCE. Some states do not allow the exclusion or limitation of incidental or consequential damages,
so the above limitation may not apply to you.
This warranty gives you specific legal rights. You also have other rights from state to state.
