ventilation is plentiful. Exhaust gases contain carbon monoxide, a colorless, odorless and  
extremely dangerous gas that can cause unconsciousness or death. Symptoms of carbon  
monoxide poisoning include: dizziness, nausea, headaches, sleepiness, vomiting or  
incoherence. If you or anyone else experiences these symptoms, get out into fresh air  
immediately. Stop the engine and do not restart the engine until it has been inspected and if  
necessary repaired or reinstalled in a well ventilated area.  
WARNING: Hot exhaust gasses must never be directed toward anything that may catch fire or explode.  
WARNING: This generator must not be used on or near any forest covered, brush covered, or grass  
covered land unless the engine’s exhaust system is equipped with a spark arrestor. The  
spark arrestor must be maintained in effective working order by the operator.  
WARNING: Some parts of this generator rotate during operation. Rotating parts can present extreme  
danger if clothing or body extremities are caught by the rotating part and can cause serious  
or fatal injury. Never touch a part of the generator until the engine has been stopped and all  
rotating parts are completely stopped. Also, disconnect the spark plug wires and battery  
connection to prevent accidental engine rotation during servicing.

WARNING: Be sure that you understand how to stop the engine quickly in case of an emergency situation.  
Become familiar with the controls and safety systems provided with this generator set.  
WARNING: Always wear safety glasses with side shields and hearing protection when working near the  
generator.  
WARNING: Improper operation may cause violent motion of connected equipment. Be certain that  
unexpected movement will not cause injury to personnel or damage to equipment.  
WARNING: Never operate the generator set indoors or in a poorly ventilated area such as a tunnel or cave.  
Exhaust fumes are extremely dangerous to all personnel that are in or in contact with that area.  
WARNING: Never permit anyone to operate the generator without proper instructions. Be sure to keep a  
copy of this manual with the generator so that all users can be properly informed of its safe  
operation.  
WARNING: Never allow children or pets to be in the area where the generator is running. The generator  
and the equipment being powered by the generator may cause injury or death.  
WARNING: Never operate the generator unless all guards, covers, shields and other safety items are  
properly installed.  
WARNING: Do not put hands, feet, tools clothing or other objects near rotating parts such as drive shaft,  
pulley, belt etc. Rotating parts cause extremely dangerous situations because they can catch  
loose clothing or extremities and cause serious or fatal injury.  
WARNING: When operating this generator remain alert at all times. Never operate machinery when  
physically or mentally fatigued, or while under the influence of alcohol, drugs or medication.  
WARNING: Never operate the engine when the air cleaner is removed. An engine backfire can cause  
serious burns.  
WARNING: Never “jump start” a generator to start the engine. If the battery charge is insufficient to start  
the engine, charge or replace the battery and try to restart. Jump starting a battery can cause  
the battery to explode and cause severe injury or death to anyone in the area.  
WARNING: High voltage is present whenever engine is running. Electrical shock can cause serious or  
fatal injury. Never operate electrical equipment while standing in water, on wet ground or with  
wet hands, feet or shoes or while barefoot.  
WARNING: High voltage is present whenever the engine is running. Electrical shock can cause serious  
or fatal injury. Always stop engine before connecting or disconnecting power cords or  
external devices.  
WARNING: Do not smoke near generator during operation or when close to fuel source. LPG and natural  
gas fuels are flammable and can cause fire, explosions, injury or death.  
WARNING: Keep generator at least three feet away from buildings and other structures.  
WARNING: Keep generator away from flammable or hazardous materials (trash, rags, lubricants,  
explosives, paints etc.) and grass or leaf build up.  
WARNING: Keep a fire extinguisher near the generator while generator is in use. An extinguisher rated  
“ABC” by the National Fire Protection Association is appropriate.  
Burn  
WARNING: Parts of this generator are extremely hot during and after operation. To prevent severe burns,  
do not touch any part of the generator until you have first determined if the part is hot. Wear  
protective clothing and after use allow sufficient time for parts to cool before touching any  
part of the generator.  
WARNING: Do not touch the hot exhaust parts or the high voltage spark plug or coil terminals of the  
engine. Although spark plug voltages are not normally lethal, a sudden involuntary jerk of the  
hand or body part caused by contact with high voltage or a hot surface can result in injury to  
yourself or others.  
WARNING: Engine coolant is under pressure and is near the boiling point of water when engine is hot.  
Do not open the coolant system until the engine has completely cooled. Hot coolant can  
cause severe burns and other injuries. When engine is cool, coolant level can be checked.

Warning Statements Continued  
Installation  
WARNING: Installation and servicing of batteries is to be performed or supervised by personnel  
knowledgeable of batteries and the required precautions. Keep unauthorized personnel away  
from batteries.  
WARNING: Disconnect the battery’s ground terminal before working in the vicinity of the battery or  
battery wires. Contact with the battery can result in electrical shock when a tool accidently  
touches the positive battery terminal or wire. The risk of such shock is reduced when the  
ground lead is removed during installation and maintenance.  
WARNING: An open bottom stationary engine generator set must be installed over noncombustible  
materials and shall be located such that it prevents combustible materials from accumulating  
under the generator set.  
WARNING: Installation and repair procedures requires specialized skills with electrical generating  
equipment and small engine systems. Any person that installs or performs repairs must have  
these specialized skills to ensure that the generator set is safe to operate. Contact Baldor for  
installation or repairs.  
WARNING: Be sure all wiring complies with the National Electrical Code (NEC) and all regional and local  
codes or CE Compliance. Improper wiring may cause a hazardous condition and exposure to  
electrical hazards can cause serious injury or death.  
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power before  
you ensure that grounds are connected. Electrical shock can cause serious or fatal injury. NEC  
requires that the frame and exposed conductive surfaces (metal parts) be connected to an  
approved earth ground. Local codes may also require proper grounding of generator systems.  
WARNING: Never allow the exhaust outlet to be positioned so that the exhaust gases are directed  
towards any openings or air entry routes (doors, windows, vents, etc...) of an occupied  
building. When discharging the hot exhaust gases out of the building do not direct them  
towards anything that could catch fire or explode.  
WARNING: Place protective covers over all rotating parts such as drive shaft, pulley, belt etc. Rotating  
parts cause extremely dangerous situations because they can catch loose clothing or  
extremities and cause serious or fatal injury.  
WARNING: Unauthorized modification of a generator set may make the unit unsafe for operation or may  
impair the operation of the unit. Never start a generator set that has been modified or  
tampered with. Be sure that all covers and guards are properly installed and that the unit is  
safe before starting the engine. If you are unsure, contact Baldor before starting the engine.  
WARNING: When moving the generator, use reasonable caution. Be careful where you place fingers and  
toes to prevent injury “Pinch Points”. Never try to lift a generator without a hoist or lift means  
because they are heavy and bodily injury may result.  
Warning: Never connect this generator to the electrical system of any building unless a licensed  
electrician has installed an approved transfer switch. The national electrical code (NEC)  
requires that connection of a generator to any electrical circuit normally powered by means of  
an electric utility must be connected by means of approved transfer switch equipment to  
isolate the electrical circuit from the utility distribution system when the generator is  
operating. Failure to isolate the electrical circuits by such means may result in injury or death  
to utility power workers due to backfeed of electrical energy onto the utility lines.  
WARNING: Circuit overload protection must be provided in accordance with the National Electrical Code  
and local regulations.  
WARNING: Check Ground Fault Circuit Interrupt (GFCI) receptacles monthly by using the “Test” and  
“Reset” buttons.  
WARNING: Only a professional experienced technician should install a fuel supply system. LPG and  
natural gas fuels are flammable and can cause fire, explosions, injury or death. Fuel supply  
lines should be kept away from sharp objects to prevent rupture. Comply with all NFPA  
regulations and local codes for shutoff valves, regulators, fuel line type, connectors etc.  
WARNING: Have electrical circuits and wiring installed and checked by licensed electrician or qualified  
technician. Electrical shock can cause serious or fatal injury.  
WARNING: Incorrect installation of this generator set could result in property damage, injury or death.  
Connection of the generator to its fuel source must be done by a qualified professional  
technician or contractor.

Maintenance  
WARNING: Before servicing the generator set, be sure to disconnect the battery terminals to prevent  
accidental engine rotation or starting.  
WARNING: Disconnect the battery’s ground terminal before working in the vicinity of the battery or  
battery wires. Contact with the battery can result in electrical shock when a tool accidently  
touches the positive battery terminal or wire. The risk of such shock is reduced when the  
ground lead is removed during installation and maintenance.  
WARNING: Installation and servicing of batteries is to be performed or supervised by personnel  
knowledgeable of batteries and the required precautions. Keep unauthorized personnel away  
from batteries.  
WARNING: A battery presents a risk of fire and explosion because they generate hydrogen gas.  
Hydrogen gas is extremely explosive. Never jump start a battery, smoke in the area around  
the battery or cause any spark to occur in the area around the battery.  
WARNING: Do not mutilate the battery or dispose of a battery in a fire. The battery is capable of  
exploding. If the battery explodes, electrolyte solution will be released in all directions.  
Battery electrolyte solution is caustic and can cause severe burns and blindness. If  
electrolyte contacts skin or eyes, immediately flush the area with water and seek medical  
attention quickly.  
WARNING: A battery presents a risk of electrical shock hazard and high short circuit current. Electrical  
shock can cause serious or fatal injury. Never wear jewelry, watch or any metal objects when  
in the area around the battery.  
WARNING: The battery electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is  
electrically conductive and corrosive. If electrolyte contacts the skin, flush the area  
immediately with water and wash it off using soap and water. If electrolyte contacts the eyes,  
immediately flush the eye thoroughly with water and seek medical attention quickly.  
WARNING: Before cleaning, inspecting, repairing or performing any maintenance to the generator set,  
always be sure the engine has stopped and that all rotating parts have also stopped. After  
stopping, certain components are still extremely hot so be careful not to get burned. Before  
servicing the generator set, be sure to disconnect the spark plug wires and the battery  
terminals to prevent accidental engine rotation or starting.  
WARNING: Engine coolant is under pressure and is near the boiling point of water when engine is hot.  
Do not open the coolant system until the engine has completely cooled. Hot coolant can  
cause severe burns and other injuries. When engine is cool, coolant level can be checked.  
WARNING: Before servicing the generator set, be sure to disconnect the spark plug wires and the battery  
terminals to prevent accidental engine rotation or starting.  
WARNING: Inspect all wiring frequently and replace any damaged, broken or frayed wiring or wires with  
damaged insulation immediately. Electrical shock can cause serious or fatal injury.  
WARNING: Disconnect all electrical wires and load devices from generator power outlets before servicing  
the generator. Electrical shock can cause serious or fatal injury. Always treat electrical  
circuits as if they are energized.  
WARNING: Check all fuel supply piping, and their connections monthly for fuel leaks. LPG and natural  
gas fuels are flammable and can cause fire, explosions, injury or death. If a leak is found,  
replace only with approved pipe or components.

Caution Statements  
Caution: Avoid installing the generator set beside heat generating equipment, or directly below water  
or steam pipes or in the vicinity of corrosive substances or vapors, metal particles and dust.  
Heat can cause engine problems to develop and unwanted substances can cause rust or  
generator failure over time.  
Caution: Do not apply high voltage to windings (do not start the generator) in a moisturesaturated  
condition. Moisture can cause insulation breakdown, making it necessary to return the  
generator to the factory for repair, and consequent expense and loss of time.  
Caution: Use only original equipment or authorized replacement parts. Using the correct parts will  
assure continued safe operation as designed.  
Caution: Do not support the generator from the top of the frame or enclosure.  
Caution: Do not tamper with or change the engine speed. Engine speed is factory set to produce the  
correct voltage and output frequency.  
Caution: Never operate the engine without a muffler. The engine is designed to have the correct  
exhaust components installed and operating without these components can present a fire  
hazard, cause excessive exhaust gases and cause damage to engine. Inspect muffler  
periodically and replace if necessary.  
Caution: The Programmable Output Contacts selection must agree with the external control wiring  
prior to energizing the controller. Failure to do so may cause severe equipment damage.  
Caution: This generator must have a battery installed for operation. The battery is used during starting  
and during operation. If engine operation is attempted while the battery is removed, damage  
to the engine’s electrical components may result.

Section 3  
Receiving & Installation  
Receiving & Inspection When you receive your generator, there are several things you should do immediately.  
1. Observe the condition of the shipping container and report any damage immediately to  
the commercial carrier that delivered your system.  
2. Verify that the part number of the system you received is the same as the part number  
listed on your purchase order.  
3. If the system is to be stored for several weeks before use, be sure that it is stored in a  
location that conforms to published storage temperature and humidity specifications.  
Lifting the Generator When lift or hoist equipment is used to lift the generator and move it to position, be careful not  
to contact overhead wires or other obstacles. The generator can weigh as much as 1,500 lbs. Be  
sure lift or hoist equipment has appropriate tires for the terrain to avoid becoming stuck or tipping  
over. If the shipping pallet is intact, use a fork lift to move the generator. If the shipping pallet has  
been removed, use two steel pipes through the “Lift Point” holes to lift the generator. See Figure 3-1.

Physical Location The mounting location of the system is important. It should be installed in an area that is  
protected from direct harmful gases or liquids, dust, metallic particles, shock and vibration.  
It should be installed in an outdoor location so the exhaust fumes are vented to the atmosphere.  
WARNING: An open bottom stationary engine generator set must be installed over noncombustible  
materials and shall be located such that it prevents combustible materials from accumulating  
under the generator set.  
Outdoor Location with Baldor Supplied Enclosure  
If the generator is installed outdoors there should not be a cooling problem. The factory installed  
enclosure is designed to keep out undesirable weather elements while providing cooling and  
ventilation. It should be installated on a concrete pad with at least thirtysix (36) inches  
clearance on all sides for air flow.  
1. For effective cooling and maintenance, the system should be installated on a concrete pad  
with at least thirtysix (36) inches clearance on all sides for air flow and service access.  
2. Installation should prevent water levels from reaching the generator. Drainage must be  
adequate to keep concrete pad free from standing water.  
3. Installation should prevent obstructions by buildup of leaves, grass, sand, snow, etc. If  
these items pose a problem, consider building a small fence or other break to protect  
the unit from accumulation of debris.  
Indoor Location Open Frame Configuration  
When the Generator is installed in a building it is essential to provide:  
1. Adequate control and exhausting of the heated air.  
2. An adequate and constant supply of incoming cooling air.  
3. Adequate control and discharge of the engine’s hot exhaust gases.  
4. Adequate ventilation of the building when the engine shuts down.  
Several other factors should be carefully evaluated when selecting a location for installation:  
1. For effective cooling and maintenance, the system should be mounted on a flat, smooth,  
non-flammable level surface. A concrete pad is ideal and provides a secure installation.  
2. Installation should prevent water levels from reaching the generator. Drainage must be  
adequate to keep concrete pad free from standing water.  
3. Installation should prevent obstructions by buildup of leaves, grass, sand, snow, etc. If  
these items pose a problem, consider building a small fence or other break to protect  
the unit from accumulation of debris.  
4. Installation should place the generator as close as possible to the fuel supply and  
transfer switch.  
5. At least fortyeight (48) inches clearance must be provided on all sides for air flow.  
6. Maximum Ambient temperature is 122°F (50°C).  
Engine Cooling  
A sufficient flow of clean, cool air is required for combustion and to dissipate the heat produced  
by the engine. Approximately 60% of the heat value of the fuel used is given off as heat (cooling  
air and exhaust).  
The air that will cool the engine must be brought in from outside the building. A sufficient airflow  
of rate “Cubic Feet per Minute” (CFM) will allow the incoming fresh air to cool the engine. This  
requires a power ventilation system of sufficient CFM to be located at the highest possible point  
of the building to exhaust hot air and draw in cool fresh air. For 812KW we recommend an  
exhaust fan of at least 2000 CFM.  
Note: The exhaust fan must not be located where it could easily become blocked by leaves,  
snow, water, debris, etc.

Indoor Location Continued  
It is recommended that the cool air intake have at least three (3) times the crosssectional area  
of the power ventilation system. It is also recommended that the cool air intake be located as  
close as possible to the top of the generator set.  
The exhaust fan must be connected to the AC power terminals of the generator set so that when  
the generator set starts it will provide immediate cooling air flow. The fan will operate until the  
generator set stops.  
Ventilation Test  
To test the ventilation system, do the following:  
1. Place a thermometer as close as you can to the cool air intake of the engine’s blower  
housing but do not let the thermometer touch any material surface.  
2. Place another thermometer outside the building or compartment in the open air. (Keep  
the thermometer out of direct sunlight or any other heat sources).  
3. Run the engine under maximum load for an extended period of time (at least one hour).  
4. The temperature difference between the two should not exceed 15 degrees F.  
Note that opening any door, window or other opening can upset the airflow pattern and result in  
a significant reduction in the cooling airflow across the generator set. This may result in  
overheating, fire, or explosion. To find out if this is true with your specific application run the  
Ventilation Test with all doors and windows closed. Then repeat this test with different doors and  
windows open, and eventually with all the windows and doors open. If any of these tests result in  
a temperature difference in excess of 15° F, you must not run the generator set under those  
specific conditions.  
Hot Exhaust Gasses  
WARNING: Exhaust fumes/gases are extremely dangerous and can cause severe illness or death. Never  
breath exhaust fumes produced by a running engine. Only run the engine outdoors where  
ventilation is plentiful. Exhaust gases contain carbon monoxide, a colorless, odorless and  
extremely dangerous gas that can cause unconsciousness or death. Symptoms of carbon  
monoxide poisoning include: dizziness, nausea, headaches, sleepiness, vomiting or  
incoherence. If you or anyone else experiences these symptoms, get out into fresh air  
immediately. Stop the engine and do not restart the engine until it has been inspected and if  
necessary repaired or reinstalled in a well ventilated area.  
WARNING: Hot exhaust gasses must never be directed toward anything that may catch fire or explode.  
WARNING: Never allow the exhaust outlet to be positioned so that the exhaust gases are directed  
towards any openings or air entry routes (doors, windows, vents, etc...) of an occupied  
building. When discharging the hot exhaust gases out of the building do not direct them  
towards anything that could catch fire or explode.  
WARNING: Exhaust fumes/gases are extremely dangerous and can cause severe illness or death. Never  
breath exhaust fumes produced by a running engine. Only run the engine outdoors where  
ventilation is plentiful. Exhaust gases contain carbon monoxide, a colorless, odorless and  
extremely dangerous gas that can cause unconsciousness or death. Symptoms of carbon  
monoxide poisoning include: dizziness, nausea, headaches, sleepiness, vomiting or  
incoherence. If you or anyone else experiences these symptoms, get out into fresh air  
immediately. Stop the engine and do not restart the engine until it has been inspected and if  
necessary repaired or reinstalled in a well ventilated area.  
It is extremely important to discharge engine exhaust gasses away from the engine and out of  
the building. The direction of the discharged hot air and hot exhaust gases is important as they  
have the potential to create brown spots on the lawn. In extreme cases this extremely hot air  
could cause dried grass or other debris to ignite.  
Guidelines for Exhaust System  
1. It is extremely important that you do not allow the hot exhaust gases to recirculate into  
the engine’s cooling air intake.  
2. The exhaust system is subject to the engine’s vibration and it must therefore be solidly  
secured to reduce mechanical stress and the potential for breakage.  
3. The engine’s exhaust system is the hottest component of the installation and extreme  
care and considerations must be given to it.

Indoor Location Continued  
4. Keep all fuel and its associated piping away from all components of the engine exhaust  
system.  
5. The exhaust system should be inspected on a regular basis to assure there are no  
toxic exhaust gas leaks. In some areas this inspection may be provided by your local  
public service.  
6. A carbon monoxide tester may be installed to detect the presence of the deadly gas  
during times when you are in the building with the engine running (during testing or  
maintenance).  
Installation  
The generator is completely assembled, tested and adjusted at the factory before it is shipped to  
you. The procedures presented in this manual are suggestions and it is the responsibility of the  
Owner/Operator to arrange for these procedures to be performed by licensed contractors  
according to all applicable codes including local codes for your Municipality/City/County and  
State. Installation generally includes the following:  
1. Secure Generator to concrete pad.  
2. Connect Fuel Supply.  
3. Electrical Connections power wiring (optional transfer switch) and control wiring.  
4. Battery (not included).  
5. Ground Connection.  
After installation, the post installation checks must be performed prior to starting the engine.  
After these checks have been performed and the system operation is verified to be good, refer to  
Section 6 Maintenance for periodic checks that must be performed at scheduled intervals to  
ensure continued operation with minimal problems.  
Secure the Generator  
Refer to Table 3-1 for the dimensions and weight of each generator. Mounting bolts in the base  
remove the shipping pallet.

General Considerations  
1. A generator set needs the engine to deliver 2 hp of energy to the alternator for every  
1000 watts of electric output power (example: an 8000 watt generator needs the engine  
to deliver 16 hp of energy to the generator end).  
2. An engine needs 10,000 BTU’s of fuel energy per horsepower of engine power to  
provide a sufficient supply of fuel (example: a 16 Hp engine needs 160,000 BTU’s of  
fuel energy for it to work properly). This fuel must be supplied to the regulator on the  
generator set at a pressure indicated in Table 3-2. To achieve this pressure in an L.P.  
regulator or a regulator system of 2 or more regulators.  
3. There are 2,516 BTU’s in one cubic foot of Propane (LP Fuel).  
There are 1,096 BTU’s in one cubic foot of Natural Gas.  
4. There are 36.39 cubic feet in one gallon of Propane.  
There are 57.75 cubic feet in one gallon of Natural Gas.  
5. There are 8.58 cubic feet per pound of Propane.  
There are 23.56 cubic feet per pound of Natural Gas.  
6. When installing the piping for the gaseous fuel supply please refer to the pipe chart in  
7. If copper tubing is used, it should be “K” or “L” having a minimum wall thickness of  
0.032 inches. Black Iron Pipe is recommended but follow building codes for your area.  
The following pamphlets are available from:  
National Fire Protection Association (NFPA) P.O. Box 9101 Quincy, MA 02269  
No. 37 Combustion Engines  
No. 54 Gaseous Appliances and piping  
No. 58 Storage and handling LPG  
Example: Determining Pipe Size for Natural Gas  
An AE8 has a 16Hp engine. For Natural Gas fuel, determine the supply pipe size for 60 feet run.  
16 x 10,000 = 160,000 BTU’s / per hour for proper operation.

Electrical Connections Class 1 wiring methods must be used for field wiring connections to terminals of a class 2  
circuit. It is the responsibility of the owner/operator to arrange for these procedures to be  
performed by a licensed electrical contractor and ensure conformance to all applicable codes  
including local codes peculiar to your municipality/city/county and state. Wire size and insulation  
type should be as required by NEC (National Electrical Code) and local codes.  
Warning: Never connect this generator to the electrical system of any building unless a licensed  
electrician has installed an approved transfer switch. The national electrical code (NEC)  
requires that connection of a generator to any electrical circuit normally powered by means of  
an electric utility must be connected by means of approved transfer switch equipment to  
isolate the electrical circuit from the utility distribution system when the generator is  
operating. Failure to isolate the electrical circuits by such means may result in injury or death  
to utility power workers due to backfeed of electrical energy onto the utility lines.  
Warning: Incorrect installation of this generator set could result in property damage, injury or death.  
Connection of the generator to its fuel source must be done by a qualified professional  
technician or contractor.  
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power  
before you ensure that grounds are connected. Electrical shock can cause serious or fatal  
injury. NEC requires that the frame and exposed conductive surfaces (metal parts) be  
connected to an approved earth ground. Local codes may also require proper grounding of  
generator systems.  
Intended Use The intended purpose of this generator set is to provide emergency power when the main utility  
power supply is interrupted. Therefore, it is important that all the wiring that connects the  
generator set with your house, transfer switch, distribution box, battery charger, etc. be properly  
installed.  
Circuit Protection Circuit protection is not provided with the generator. When connecting the generator output  
to an electrical load, a UL listed circuit breaker with the appropriate ratings shall be provided  
within 25 feet of the genset. Use only copper wires.

Transfer Switch Considerations  
The following are general considerations for the safe use of a transfer switch:  
1. The transfer switch should be located inside the building near the main breaker box or  
the disconnect box.  
2. The transfer switch must be kept away from any location that might allow water to get  
on it.  
3. If the transfer switch is mounted outside, it must be protected from the environment.  
4. Do not mount the transfer switch on the generator set.  
5. Do not mount the transfer switch where flammable liquids or vapors are present.  
Battery Charger Considerations  
1. Mount the battery charger on the generator or as close to the generator as possible.  
2. If you mount the battery charger inside the building, mount it near the main breaker box  
or disconnect box.  
3. If you mount the battery charger outside, you must protect it from the environment.  
4. Do not mount the battery charger where flammable liquids or vapors are present.

General Wiring Considerations  
1. Control wires and Power wires cannot be located in the same conduit (NEC Article 725).  
2. When routing the interface wiring, do not route it up against anything that could cut or  
chafe the wiring. do not route the wire up against any hot or potentially hot object.  
3. Make sure that all the electrical components (generator set, transfer switch, battery  
charger, etc.) share a common hardwired ground.  
4. Check with your local building inspector to determine what you must do to comply with  
the local regulations for grounding of this type of permanent installation.

Frame Ground Connection  
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power  
before you ensure that grounds are connected. Electrical shock can cause serious or fatal  
injury. NEC requires that the frame and exposed conductive surfaces (metal parts) be  
connected to an approved earth ground. Local codes may also require proper grounding of  
generator systems.  
It is important for safety reasons that the Generator set, transfer switch and battery charger share  
a common Ground and neutral.  
The NEC requires that the frame and exposed metal surfaces be at local ground reference  
potential to avoid electrical shock hazard. A local ground reference may require a driven earth  
ground conductor at the generator installation site. Make the ground connection as shown in

Caution: This generator must have a battery installed for operation. The battery is used during starting  
and during operation. If engine operation is attempted while the battery is removed, damage  
to the engine’s electrical components may result.  
Battery Connections AE8, AE10, AE11, and AE25. The generator is shipped with no battery installed.  
WARNING: Installation and servicing of batteries is to be performed or supervised by personnel  
knowledgeable of batteries and the required precautions. Keep unauthorized personnel away  
from batteries.  
WARNING: Do not dispose of battery or batteries in a fire. The battery is capable of exploding. If the  
battery explodes, electrolyte solution will be released in all directions. Battery electrolyte  
solution is caustic and can cause severe burns and blindness. If electrolyte contacts skin or  
eyes, immediately flush the area with water and seek medical attention quickly.  
WARNING: Do not mutilate the battery . The battery contains electrolyte solution which is caustic and  
can cause severe burns and blindness. If electrolyte contacts skin or eyes, immediately flush  
the area with water and seek medical attention quickly.  
WARNING: A battery presents a risk of electrical shock hazard and high short circuit current.  
The following precautions are to be followed when working on batteries:  
1. Remove watches, rings, necklaces and all other metal objects.  
2. Use tools with insulated handles.  
3. Wear rubber gloves and boots.  
WARNING: The battery electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is  
electrically conductive and corrosive.  
The following precautions are to be followed when working on batteries:  
1. Wear full eye protection (safety glasses or goggles) and protective clothing.  
2. Where electrolyte contacts the skin, flush the area immediately with water and wash it  
off using soap and water.  
3. Where electrolyte contacts the eyes, immediately flush the eye thoroughly with water  
and seek medical attention quickly.  
4. Spilled electrolyte is to be washed down with an acid neutralizing agent. A common  
practice is to use a solution of one pound (500 grams) bicarbonate of soda to one  
gallon (four liters) of water. The bicarbonate solution is to be added until evidence of  
reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the  
area dried.  
WARNING: A battery presents a risk of fire because they generate hydrogen gas. Hydrogen gas is  
extremely explosive. Never jump start a battery, smoke in the area around the battery or  
cause any spark to occur in the area around the battery.  
The following precautions are to be followed when working on batteries:  
1. Do not smoke when near batteries.

Post Installation Checks  
When the initial installation is complete, these checks must be performed before starting the  
engine. These checks are not required before each start, only after the initial installation.  
Caution: Do not apply high voltage to windings (do not start the generator) in a moisturesaturated  
condition. Moisture can cause insulation breakdown, making it necessary to return the  
generator to the factory for repair, and consequent expense and loss of time.  
Note: These precautions are especially necessary in locations such as seaboard installations  
and other high humidity areas. Some installations will be in atmospheres that are much  
more corrosive than others. Prevention of a failure is better than being forced to make a  
repair.  
1. Generators that have been in transit or storage for long periods may be subjected to  
extreme temperature and moisture changes. This can cause excessive condensation,  
and the generator windings should be thoroughly dried before bringing the generator

22. The engine should begin to crank and start when the fuel moves through the pipe to  
the carburetor. If the engine fails to start, refer to Section 5 Troubleshooting.  
23. With the engine running, several checks must be made:  
a. Verify there are no fuel leaks. If a fuel leak is detected, stop the engine (move the  
Master Control Switch to the “Stop” position) immediately and repair the leak  
before proceeding.  
b. Verify there are no coolant or oil leaks. If a leak is detected, stop the engine  
(move the Master Control Switch to the “Stop” position) immediately and repair the  
leak before proceeding.  
c. Verify that operation is smooth. If belt squeals, vibrations or other sources of  
noise exist, stop the engine (move the Master Control Switch to the “Stop”  
position) immediately and repair before proceeding.  
d. Verify that the correct voltage exists (linetoline and linetoneutral) at the  
generator and at the transfer switch.

Download from Www.Somanuals.com. All Manuals Search And Download.  
Operating Procedures The enginegenerator controller is designed to start and stop an engine from either a local  
mode “Manual Run” or remote mode “Auto Start”. When a start command is issued, the controller  
issues a run and crank output signal. The controller then monitors engine speed and when crank  
disconnect speed is reached, the crank signal is terminated. While the engine accelerates to  
normal speed, the controller continuously monitors the engines speed signal. Should the engine  
speed exceed the maximum predetermined setpoint, the Overspeed shutdown fault circuit will  
activate, terminating the run signal.  
In addition to Overspeed shutdown, other engine functions are also monitored and the engine will  
automatically stop for any shutdown fault. The engine will also stop, or when the remote start  
signal is removed or local Stop is pressed. The engine controller operation includes time delay  
circuits for normal operating conditions such as start delays, cool down and cranking periods.  
Manual Start/Stop All models.  
Push the Manual Run button to immediately initiate the engine crank cycle to start the engine  
and generate AC power. This mode does not require a start command from a remote device but  
operates immediately when the button is pushed. When pushed, the following happens:  
1. The Engine Crank cycle begins.  
2. When the engine starts and accelerates to nominal speed, the controllers speed sensor  
will terminate the Engine Crank cycle.  
Manually Stop the GeneratorSet at anytime by simply pushing the “Stop” button. The  
controllers RUN output will be immediately terminated which will initiate the engine stop  
sequence.  
Automatic Start/Stop All models.  
Push the “AutoStart” pushbutton. The following happens:  
1. The engine will automatically start upon activation of the remote start contact input. The  
remote device (transfer switch) initiates a start sequence when utility power fails.  
2. When the remote start signal is activated, the engine will start.  
3. The automatic stop sequence will be initiated by removal of the remote start signal.  
4. When the start signal is removed, a cool down delay function will be initiated.  
5. When the cool down time delay period expires (typically 5 minutes), the controllers  
RUN output will be immediately terminated which will initiate the engine to stop.  
Manually Stop the GeneratorSet at anytime by simply pushing the “Stop” button. The  
controllers RUN output will be immediately terminated which will initiate the engine stop  
sequence.  
Automatic Fault Shutdown AE11 and AE25.  
When a fault circuit is programmed as a Shutdown, the engine will immediately stop when the  
fault is activated. A specific shutdown fault can be programmed with a definite time transient  
delay period that must expire before the shutdown is activated. The stop sequence will cause the  
controllers RUN output to be immediately terminated which will cause the engine to stop.  
A Warning lamp does not terminate generator set operation. It only warns that a condition  
exists. (alternator charge failure, etc.) but allows generator operation to continue.

AE11 Operating Procedures  
The AE11 engine controller is programmable and it’s internal workings is more complex than the  
other AE series generators.  
Auto Start Operation  
from the transfer switch or other device is activated. To prevent a false remote start, the Start  
Delay timer is initiated. If the Remote Start signal is removed during the Start Delay timer, the  
unit returns to standby. After the Start Delay, if the preheat output option is selected, the  
preheat timer is starts, and the corresponding auxiliary output (if configured) will energize.  
After these delays, the Fuel Solenoid is energized, then one second later, the Starter Motor is  
engaged. The engine is cranked for a 10second period. If the engine fails to start, the starter  
motor is disengaged for a 10second rest period. Should this sequence continue beyond the 3  
starting attempts, the start sequence will be terminated and Fail to Start fault will be illuminated.  
When the engine starts, the starter motor is disengaged and locked out at 20 Hz measured at the  
Alternator output. (Rising oil pressure can also be used to disconnect the starter motor, however  
it cannot be used for under speed or over speed detection).  
When the starter motor has disengaged, the Safety On timer starts. This timer is preset to 12  
seconds and allows engine speed, Oil Pressure, High Engine Temperature, Underspeed,  
Charge Fail and Auxiliary fault inputs to stabilize without triggering a fault. Once the engine is  
running, the Warm Up timer starts (if selected). This allows the engine to stabilize before the  
load is switched on. After the Warm Up delay, the AC output is switched on to operate the load.  
When the Remote Start signal is removed, the Stop Delay timer is initiated. After which the Load  
Transfer output (if configured) is deactivated, and the Cool Down Period is initiated. After the  
Cool Down Period has elapsed, the Fuel Solenoid is deenergized, bringing the generator to a  
stop.  
Manual Operation There is no “Start Delay” in Manual Run.  
configured) will energize. After this delay, the Fuel Solenoid is energized, then one second later,  
the Starter Motor is engaged. The engine is cranked for a 10second period. If the engine fails to  
start, the starter motor is disengaged for a 10second rest period. Should this sequence continue  
beyond the 3 starting attempts, the start sequence will be terminated and Fail to Start fault will be  
illuminated. When the engine starts, the starter motor is disengaged and locked out at 20 Hz  
measured at the Alternator output. (Rising oil pressure can also be used to disconnect the starter  
motor, however it cannot be used for under speed or over speed detection).  
When the starter motor has disengaged, the Safety On timer starts. This timer is preset to 12  
seconds and allows engine speed, Oil Pressure, High Engine Temperature, Underspeed,  
Charge Fail and Auxiliary fault inputs to stabilize without triggering a fault. Once the engine is  
running, the Warm Up timer starts (if selected). This allows the engine to stabilize before the  
load is switched on. After the Warm Up delay, the AC output is switched on to operate the load.  
The generator will continue to run until the “Stop” or “Auto Start” mode is selected.  
If Auto mode is selected, the Remote Stop Delay Timer starts. After this delay, the Fuel Solenoid  
is deenergized, to stop the generator.  
Selecting Stop deenergizes the Fuel Solenoid is deenergized, to stop the generator.  
Warnings and Shutdowns  
Warnings  
Warnings are used to warn the operator of a problem fault. Battery Charge Failure, if the module  
does not detect a voltage from engine mounted alternator, the lamp will illuminate. (Either 8 Volts  
or 16 Volts depending on the configuration of Nominal DC Voltage). Inputs 1 and 2 can be  
configured as warnings or shutdowns. The lamp will be illuminated when the input is active.  
Shutdowns  
Shutdowns are latching and stop the Generator. The alarm must be cleared, and the fault  
removed to reset the module. In the event of a shutdown the appropriate lamp is illuminated.  
The alarm condition must be corrected before a reset will take place. If the alarm condition  
remains it is not possible to reset the unit (except faults that occur during the “Safety On timer”  
period. These are delayed alarms, like oil pressure is low with the engine at rest).  
Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant lamp is illuminated  
when the input is active.

Shutdowns Continued  
Fail To Start if the engine does not start after 3 start cycles, a shutdown will be initiated and  
the Fail to Start Shutdown lamp is On.  
Low Oil Pressure if engine oil pressure is less than the low oil pressure limit (after the Safety  
On timer), a shutdown will occur and the Low Oil Pressure Shutdown lamp is On.  
High Engine Temperature if engine coolant temperature exceeds the high engine  
temperature limit (after the Safety On timer), a shutdown will occur and the High Engine  
Temperature Shutdown lamp is On.  
Overspeed if engine speed exceeds the preset limit (14% above the nominal frequency), a  
shutdown will occur and the Overspeed Shutdown lamp is On. The Overspeed shutdown is not  
delayed, shutdown is immediate.  
Note: During startup the Overspeed trip level is extended to 24% above the normal frequency  
for the duration of the safety timer to allow an extra trip level margin. This prevents  
nuisance tripping during startup.  
Underspeed if engine speed goes below the preset trip (20% of the nominal frequency) after  
the Safety On timer delay, a shutdown will occur and the Underspeed Shutdown lamp is On.  
Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant lamp is illuminated  
when the input is active.  
Editing the Configuration  
The 4110 engine controller is fully configurable from the front panel. There is no requirement for  
a computer or software.  
Access Configuration Editor Figure 4-4.  
With the unit is in Stop mode, Configuration Mode is selected by a small switch on the rear,  
bottom edge of the printed circuit board. This is partially hidden to prevent accidental operation.  
When Configuration Mode is selected, the “Auto” LED will flash rapidly, and all normal operations  
are suspended.

Garretson Model KN Fuel Valve Considerations  
General  
The KN is designed for sensitivity and simple operation. It is used with lowpressure vaporized  
gaseous fuels, where dependable starting is a requirement. Because of its extreme sensitivity,  
the KN offers excellent results in most remote starting applications (Standby power generators,  
etc.). With proper installation and maintenance, the KN will provide years of troublefree service.  
Operation  
The KN is an atmospheric zero governor which acts like the float and needle valve in a gasoline  
carburetor. Airflow through a venturi in the carburetor creates a vacuum, which acts through the  
outlet of the KN on the diaphragm. Atmospheric pressure then forces the diaphragm toward the  
vacuum, depressing the lever and pulling the valve seat away from the orifice, which allows fuel  
to flow as long as the demand persists. When the vacuum ceases, a spring force pushes on the  
lever and forces the valve seat against the orifice shutting off the fuel flow. It is important to  
remember that fuel should not flow through the KN when the engine is not running.  
A properly adjusted KN requires a vacuum of only 0.25” to 0.35” of water column to start the  
opening sequence. Due to this sensitivity, most installations do not need priming to start unless  
low cranking speeds or restricted and lengthy piping are required. If priming is necessary and a  
manual primer is installed, use only 1 or 2 second bursts of fuel and immediately try to start the  
engine. If there is a choke on the carburetor, do not use it as this will probably cause flooding and  
hard starting. As you can see, the operation of this unit is simple and basic. If you are having  
trouble operating the engine, in most cases the fuel controller is not malfunctioning. There is  
generally a problem with the engine or fuel supply. so do not make adjustments or attempt to  
service the KN until you are sure it is needed.

Service  
The KN should be periodically checked for leakage past the valve seat and the vents on the  
cover kept clean and free of obstructions. If the KN needs service we suggest you take it to a  
qualified serviceman. If that help is not available Garretson will furnish you a list of repair shops  
with the proper service information.  
Installation  
The KN should be mounted as close to the carburetor as possible with the arrow on the cover  
pointing up and the diaphragm in a vertical position. This helps to minimize the effects of gravity  
on diaphragm travel. This unit should also be placed for easy access to the primer if provided.  
There are two sets of mounting holes provided. either set of mounts will adequately support the  
KN. The bottom set of holes has a 1 3/4” bolt spacing for use with all Garretson universal  
mounting brackets. The mounting bosses on the cover are spaced (5 3/4”) for 5/16 bolts.  
Before installing the fuel supply line, be sure that the gas pressure is no more than the maximum  
inlet pressure shown on the front of the KN. If the pressure is greater, leakage could result in a  
fire hazard and or hard starting. The piping to the inlet should be of sufficient size to allow full  
flow to the KN. This is very important in natural gas installations as any restrictions can affect  
engine performance. If a solenoid is used ahead of the KN in the lowpressure line, it should  
have an orifice at least as big as the orifice in the KN. Flexible piping to the inlet should be used  
to prevent cracking from vibration if the KN is mounted on the engine or other vibrating surface.  
Note: Thread sealing compound should be used on all pipe thread fittings between the KN and  
the fuel supply tank, being careful not to get any inside the inlet or fittings. Excess  
compound could collect on the seat and orifice and cause hazardous leakage, resulting in  
poor performance. After piping is complete, turn on the gas and use a soap solution to  
check all fittings for leaks.  
If an electric solenoid primer is used, follow the wiring and adjusting instructions furnished  
separately. kit by connecting into a pressure line at a reduced pressure, call us. The KN outlet is  
3/8 NPT and if an outlet fitting has not been provided, select and insert a suitable vapor fitting  
taking care not to allow any chips or dirt to enter the outlet. Use of street ells or conventional pipe  
fittings in the fuel line between the KN and the carburetor is not recommended as they may  
restrict the flow of fuel.  
When installation of a properly sized fuel hose between the KN and carburetor is completed, if  
you are installing a complete conversion return to the instructions. For field replacement  
applications the unit is ready for service.

Troubleshooting and Maintenance  
Maintenance  
This manual contains only very minimal engine maintenance instructions. Refer to the engine  
manufacturer’s owner’s manual for specific engine maintenance instructions for your generator  
set. Any maintenance instructions or recommendations in the engine owner’s manual take  
precedence over any of the following general recommendations.  
General:  
1. Inspect the fuel system for leaks. Replace all defective components immediately.  
2. Inspect and replace any fuel line that shows signs of deterioration.  
3. Inspect all the fuel clamps to ensure they are tight.  
4. Inspect and clean the battery posts and the associated battery cable terminals.  
5. Inspect the external wire cables and connectors used with the generator set for cuts,  
fraying, or loose connections. Repair or replace any problems prior to using the unit.  
Engine:  
1. Clean and/or replace any fuel, oil, and/or air filters per the engine manufacturers’  
guidelines.  
2. Check oil level regularly; at least every 5 to 8 operating hours. Maintain the proper oil  
level.  
3. Change the oil as is recommended in the engine manufacturer’s owner’s manual.  
4. Replace the spark plug(s) as is recommended by the engine manufacturer.  
5. Clean the cooling fins on the engine to keep the engine’s heat dissipation potential at  
it’s maximum.  
6. Inspect and clean all governor and carburetor linkages so they operate properly.  
Alternator: ( also called Generator End)  
This generator set must be run at its proper speed to obtain the correct electrical power at its  
output. All engines have a tendency to slow down when a load is applied to it. The engine  
governor is designed to hold the operating speed as nearly constant as possible. When the  
electrical load is increased, the engine is more heavily loaded and engine speed drops slightly.  
This slight decrease in engine speed results in a slight decrease in generator voltage and  
frequency output. This voltage and frequency variation has no appreciable effect in the operation  
of motors, lights, and most appliances and tools. However, timing devices and clocks will not  
keep perfect time when used on this generator.  
1. Clean the generator set and remove any and all dust, dirt, or other foreign material.  
2. Inspect and clean the cooling air intake and exhaust louvers of the generator end.  
Make sure they are clean. Remove dirt or any buildup that may restrict the cooling air  
flow.  
3. Clean the generator set and its components with a damp cloth or sponge.  
Never use a water hose or pressure washer as this may damage electrical  
components.  
4. Inspect and replace any control panel components that are broken or not working  
properly (receptacles, circuit breakers, switches, etc.)
