RECEIVING YOUR NEW MODEL
Congratulations on your recent purchase of Continental Refrigerator superior food
equipment products! When your shipment arrives, please thoroughly examine the
shipping crate for any punctures, dents, or signs of rough handling. It is in your best
interest to partially remove or open the shipping container in order to examine the
model for any concealed damages which may have occurred during shipment. If the
model is damaged, it must be noted on the delivering carrier's delivery slip or bill of
lading (see “filing a damage claim” under warranty section).
GENERAL INFORMATION AND IMPORTANT OPERATING FACTS
This manual has been compiled to aid in the installation, operation and maintenance
of your new equipment. Please take the time to read all of the material in order to
become more familiar with your equipment and its operation, and enjoy optimum
performance.
No floor drains or plumbing connections are required since all models are completely
self-defrosting and use an automatic defrost condensate water evaporating system
(see “condensate evaporator pan installation” under installation and location section).
All cabinets must be given sufficient time to reach normal operating temperature
before placing any food inside cabinet or pans (if equipped). For refrigerators,
approximately 1 hour of operation is required to lower the cabinet and pan
temperature to 40°F. During pull-down of open top models, pans should be in
place and top lid should be kept closed. Freezers require approximately
2 hours of operation to lower the cabinet temperature to 0°F (see “operation”
section for further information).
On all open top refrigerators with salad pans, it is strongly recommended that the top
lid be kept in the closed position when the unit is not in use or between rush periods.
This is extremely important during the summer months and in hot kitchens. Do not
keep the top lid open for prolonged periods of time and never operate open top
models without all pans in place. Please note that sandwich and pizza preparation
tables are not intended for overnight food storage in the open top pans.
Prior to factory shipping, all models are performance run tested for a minimum of
12 hours providing a highly sophisticated temperature analysis recording exclusive
to each individual cabinet. This recording is supplied within this manual packet. A
final leak check, vibration, noise level and visual examination is made by a qualified
quality control team to assure a quality product. The carrier signs to this effect when
he accepts the product for shipping. To insure the maximum in safety and sanitation,
all models are listed under the reexamination service of underwriter's laboratories
and with the national sanitation foundation.

UNCRATING YOUR NEW MODEL
The shipping container should remain on your model as protection against
dents or scratches while transporting it to the actual set-up location. Remove
the shipping container only at the last possible moment by following these
simple steps:
1. Using a pry bar, pry off and remove crate end bottom staples.
2. Pry off and remove crate front and rear bottom staples.
3. Slide crate upward and remove it, being careful not to rub against cabinet.
There are up to four (4) bolts securing the cabinet to the wooden skid. The bolts are
located at each end on the underside of the skid. In order to remove these bolts it is
advisable to tilt the cabinet backwards and place wooden blocks at each end in order
3
to hold it in its tilted position. Using a /4" socket or open end wrench, remove the bolts
and carefully slide the model off of the skid. After skid removal, the cabinet should
never be moved without dollies or rollers to avoid damage to the cabinet bottom or
floor.
Important Note: Do not under any circumstances lay your new model on its front
or sides. Only for a brief period, may you lay the model on its back and only then,
when its properly blocked so as not to crush the louvered venting panel and also
to allow provision for your hands in order to set it in its upright position without
inflicting damage to the cabinet. Do not plug in and operate model for at least
three (3) hours after cabinet is set upright from being on its back as damage
could result to the compressor.
INSTALLATION AND LOCATION
CLEARANCES
Before moving the cabinet to its final point of installation, accurately measure all door-
ways or passages to assure clearance. If additional clearance is needed, cabinet doors
can be easily removed (see instructions outlined in “removal of doors” section) and, or
hood assembly (when equipped) can be easily removed (see instructions outlined in
“removal of hood” section).
VENTILATION
The final location site of your air-cooled refrigerator or freezer must be able to provide
a large quantity of cool, clean air. The refrigeration system operates most efficiently
and trouble-free with cool, dry air circulation. Avoid locations near heat and moisture
generating equipment such as stoves, ovens, cooking ranges, fryers, dish washers,
steam kettles, etc., and also direct sunlight where temperatures can be in excess of
100°F. Also, do not select a location in an unheated room or area where temperatures
may drop below 55°F. Air supply to the condensing unit is equally important. Restricting
the air supply will place an excessive heat load on the condensing unit and adversely
affect its operating efficiency.

Important Note: To assure maximum operating efficiency, your new “SW” series
model should be located where an unrestricted air supply can circulate underneath
and behind the cabinet. For optimum performance, the cabinet must be installed on
legs or casters (see “installing legs or installing casters” later in this section) and a min-
imum of 3" on each side and rear of the cabinet must be provided (see figure 1a). Your
model has been designed to operate sufficiently without legs or casters and directly on
the floor as long as a minimum clearance of 8" is provided from the rear venting lou-
vers and the rear wall (see figure 1b). Cabinet side clearance is not required when
mounting your model directly on the floor without legs or casters. If
necessary, special venting or air supply ducts must be installed by the installer if
any of the above conditions cannot be achieved. Do not at any time obstruct the
grill area in the rear of the cabinet in any way, and never place or store anything
inside of the cabinet machine compartment. These rules are essential for maximum
cooling capacity and long life of refrigeration parts.

MINIMUM CLEARANCE DIMENSIONS WITHOUT LEGS
FLOOR LOADS
The floor at the final location site must be level, free of vibration and strong enough
to support the total combined weights of your new model plus the maximum product
load which might be placed into it. A fully loaded reach-in model may reach 2,000 -
3,000 pounds. To estimate the possible product load weight, assume that each cubic
foot of storage space weighs approximately 35 pounds. Multiply 35 pounds by the
amount of cubic feet in the cabinet and obtain the product load weight. For example,
a 20 cubic foot refrigerator can hold approximately 700 pounds of product (35 x 20)
and assuming the refrigerator itself weighs 300 pounds, the total combined weight
of cabinet and product is approximately 1000 pounds. Therefore, the floor in this
example must be capable of supporting up to 1000 pounds.

INSTALLING LEGS AND LEVELING
Your new “SW” series model is supplied with adjustable type legs for leveling
purposes. Each SW27, SW48, SW60 and SW72 model has four leg mounting
holes on its case bottom. Legs are packed in the accessory carton from which
they must be removed and installed on the cabinet case bottom (see figure 2).
In order to install the legs, carefully tip the cabinet rearward adding four (4) 2"
wood blocks underneath and simply screw the threaded leg studs into the case
bottom front leg holes. Repeat this procedure by tilting the cabinet in the opposite
direction and install the remaining legs. Make sure the legs are tightened extremely
well or the entire model will sway or rock with each opening or closing of the doors,
possibly causing damage to the case bottom. This procedure should be performed
close to the final installation site and allow access to the rear of the cabinet for
condensate evaporator installation (see “condensate evaporator installation” under
installation and location section).
To assure your cabinet is level, all legs are equipped with bullet-type leveling bolts.
These bolts can be turned by hand or by wrench, clockwise or counterclockwise to
level the cabinet.

Important Note: It is extremely important that your new model is perfectly
level for proper operation. If it is not level, the following adverse conditions will
become apparent:
1. The door(s) will not be properly aligned and consequently will not provide
a good seal.
2. You model will run excessively due to improper door seal(s).
3. An excessive amount of ice will accumulate inside the cabinet, around the
door opening(s) and especially on the finned evaporator coil. If allowed to
continue, ice will eventually block the coil and the model will fail. This will
result in the loss of all food stored within the cabinet.
4. Defrost water will fail to drain properly and will overflow the evaporator coil
drain pan and into the cabinet of both refrigerator and freezer models.
INSTALLING CASTERS AND LEVELING
Your new “CRB” and “CPT” series models are supplied with non-adjustable casters.
To install casters on your new model, follow the steps above for “installing legs” to
install the casters, making sure again that the casters are tightened extremely well
(see figure 3). If the casters are not installed tightly, the cabinet will sway or rock
with each opening or closing of the doors, possibly causing damage to the case
bottom.
To assure that your cabinet is level, caster cups must be installed under the casters
which need leveling. Caster cups are not provided with your new model but can be
purchased at most hardware or furniture stores. Do not attempt to level casters
by unscrewing them from the case bottom as this will cause damage to the
cabinet bottom and leg hole threads, voiding all warranties.

CASTERS MUST BE TIGHT TO CABINET BOTTOM
INSTALLING CONDENSATE EVAPORATOR
No floor drains or plumbing connections are required since all models use an
automatic condensate water evaporating system. All models utilize a unique
hot air condensate water evaporating system which is completely self-contained
and no further assembly or maintenance is required. In some adverse conditions
such as high ambient temperature, high humidity, extremely heavy usage, frequent
loading for prolonged periods of time, and heavy pan loading, an optional electric
condensate evaporator pan may be purchased as an accessory. An electric
condensate evaporator pan is also supplied with all remote models. To install the
condensate pan, remove all rear cabinet cover screws and install the mounting
bracket on the case rear next to and behind the compressor as shown in figure 4.
Slide the condensate pan onto the bracket, install the drain tube into the pan
making sure it is not blocked or kinked, and plug the ten foot power cord into the
receptacle labeled “vaporizer” located on the compressor compartment electrical
box.
Important Note: It is extremely important to be sure that the condensate pan is
plugged into its correct receptacle labeled “vaporizer” and that the condensing
unit is plugged into its correct receptacle labeled “condensing unit”.

REMOVAL OF DOORS AND DOOR ADJUSTMENT
During installation, it may become necessary to remove the cabinet doors to facilitate
passage through narrow doorways or hallways. To remove a door, swing the door to
the open-door position (90°) and remove the two screws marked “a” (figure 5) while
carefully holding the door open. Care must be taken to hold the door fully open during
the screw removal since the top hinge is spring loaded and may snap towards the door
when the screws are removed. After removing both screws, carefully lift the door
straight upward to avoid bending the bottom hinge pin. To reinstall the door, reverse
the above procedure.
Caution: The top hinge is spring loaded and may snap towards the door when
the mounting screws are removed. Be sure to hold door fully open before
removing mounting screws.
All doors have been aligned at the factory, however vibration during transportation
may cause doors to shift and realignment may be necessary. If the door(s) require
realignment, proceed as follows:
1. Swing the door to the open-door position and loosen but do not remove
the screws marked “A” on both top and bottom hinges (see figure 5).
2. Relocate the door to its required position by hand or by tapping on the
door edges with a hammer and a block of wood.
3. Securely tighten all screws “A”.

DOOR ADJUSTMENT AND REMOVAL
SELF-CLOSING HINGE MECHANISM MOUNTING
For proper operation of the self-closing doors on all sandwich unit and prep models,
the hinge mechanism must be mounted to apply tension in the direction shown in fig-
ure 6. When the hinge is moved to the open-door position the hinge should be tension-
free. However, when the hinge is moved back into the closed position, it should snap
back. Caution should be taken when checking the spring loading as the hinge could
snap back on fingers. If the hinge does not respond as described above, follow these
steps:
1. Using the hinge upside down as a wrench, turn the mechanism in the
door 180 in either direction. The mechanism should snap to a null point.
2. Remount the hinge as shown in figure 6.
3. Repeat the test procedure as described above until the hinge snaps
back when it is moved from the open-door position towards the
closed-door position.

REMOVAL AND REPLACEMENT OF HINGE MECHANISM
To remove the hinge mechanism from the door, remove the door from the cabinet
as explained above. As shown in figure 6, remove the hinge plate from the hinge
mechanism by removing the hinge pin screw. Also remove the horseshoe spring.

Reinstall the hinge pin screw only partially leaving about /8" of exposed screw
threads. Now, the hinge mechanism mounting screws can be removed thus
allowing the mechanism to be removed by pulling on the hinge pin screw. If the
mechanism does not readily slide out of the door, slide a claw hammer or forked
prybar under the hinge pin screw head and using a block of wood for leverage,
lift the entire mechanism out of the door. To install the new hinge mechanism,
reverse the above procedure.
INITIAL CLEANING PROCEDURE
Prior to start-up and before placing any food inside of your new model, the interior
of the cabinet should be thoroughly cleaned. Washing with a mild soap and warm
water solution is recommended for cleaning the aluminum and stainless steel
surfaces of your cabinet. This should be followed by cleaning with a baking soda
solution (three (3) tablespoons of baking soda to each quart of warm water).
Rinse thoroughly with clear water and dry with a clean, soft cloth.
12
Download from Www.Somanuals.com. All Manuals Search And Download.
Important Note: Never use harsh detergents, cleaners, scouring powders or
chemicals when cleaning your model. Failure to dry the interior surfaces after
cleaning may result in a streaking or staining of the metal.
Complete cleaning procedures and precautions are listed in the “periodic cleaning
procedure” under the maintenance section.
START-UP PROCEDURE
ELECTRICAL CONNECTIONS
To insure proper operation, your new model must be connected to an individual
circuit that can supply the full voltage as stated on the cabinet serial data plate.
For correct voltage, power draw, and wire accommodations, check the data on the
serial data plate located on the inner right wall of your new model. Verify that this
information exactly matches the electrical characteristics at the installation location.
An electrical wiring diagram, located on the inside compressor compartment rear,
next to the electrical console box, should also be consulted during connection. For
reference, a copy of each electrical wiring diagram is located at the rear of this
manual in the “maintenance” section.
Important Note: The condensing unit supplied with all self-contained models is
designed to operate with a voltage fluctuation of + 10 % of the voltage indicated
on the cabinet serial data plate. Full voltage of the correct service, on an individual
line not affected by the operation of other electrical appliances, must be available
to the condensing unit at all times. Burnout of the compressor due to exceeding the
high or low voltage limits is easily detected and will automatically void the factory
warranty.
115 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115 volt models are provided with a U.L. approved power cord and polarized
plug which is factory installed.
Warning: Any alterations to this cord and plug could cause an electrical
hazard and will void the factory warranty.
To insure proper operation, this equipment must be plugged into a NEMA 5-15r
compatible, grounded receptacle that can supply the full voltage as stated on the
serial data plate.
13
Download from Www.Somanuals.com. All Manuals Search And Download.
208-230 VOLT, 60 HZ, 1 PHASE CONNECTION
All 208-230 volt models are to be permanently connected and are provided with
four (4) field wiring leads which exit the electrical console box located in the
machine compartment rear, next to the compressor. The cabinet circuitry is 115
volts and the condensing unit is 208-230 volts in which the wiring includes a
neutral and a mechanical ground. This wiring should be connected to the
appropriate power source by a qualified electrician and must conform to all
local electrical codes.
SPECIAL VOLTAGE CONNECTIONS
When models are ordered from the factory with special, optional voltages,
connections should be made as required on the electrical wiring diagram
provided on the inside compressor compartment rear next to the electrical
console box.
START-UP CHECKLIST
After your model has been installed, leveled, cleaned, and electrically connected
in accordance with this manual, please take the time before start-up to observe the
following precautions to assure trouble free operation:
1. Check that all exposed refrigeration lines are free of severe dents or kinks.
2. Check the condenser fan and evaporator fans for freedom to rotate without
any obstructions
3. Make sure that the cabinet is properly leveled (see “leveling” under
installation and location section).
The system should run smoothly and quietly in accordance with generally accepted
commercial standards. If any unusual noises are heard, turn the unit off immediately
and check for any obstructions of the condenser or evaporator fans. Fan motors, fan
blades, or fan housings can be jarred out of position through rough handling in transit
or during installation.
Caution: If unit is unplugged or disconnected for any reason, allow several
minutes (5-6 minutes) before turning the unit back on to allow the system
pressures to equalize. Disregarding this procedure could cause an overload
and prevent the unit from operating.
REMOTE APPLICATIONS
All models are available for purchase as remote models in which case the condensing
unit is purchased separately and installed at the time of installation. All remote models
are equipped with an expansion valve located within the evaporator coil housing, and
both liquid and suction lines stubbed and extending out from the cabinet rear behind
the rear cover. Installation of the refrigeration accessories, condensing unit, and
electrical hook-up should be performed by qualified refrigeration personnel of a
competent refrigeration company only.

OPERATION
All cabinets must be given sufficient time to reach normal operating temperature
before placing any food inside cabinet or pans (if equipped). Refrigerators are
designed to maintain an ideal cabinet and pan temperature of 38°F to 40°F
(3.3°C to 4.4°C) and approximately 1 hour of operation is required to reach this
temperature. During pull-down of open top models, pans should be in place and
top lid should be kept closed. Freezers are designed to maintain an ideal cabinet
temperature of to 0°F (-17.8°C) and approximately 2 hours of operation are required
to reach this temperature.
THERMOMETER CALIBRATION
Your new “SW” series model has a non adjustable hanging thermometer
located inside the cabinet, mounted on the coil housing cover (see figure 7).
This thermometer is maintenance-free and needs no further calibration. "CRB"
and “CPT” series models have a hanging thermometer in the accessory carton
to mount on any shelf inside the cabinet.
PIZZA PREPARATION TABLE OPERATION
Pizza prep tables are designed and factory set to maintain an average cabinet and
pan rail product temperature of 38°F. In order to maintain pan temperatures in the
raised rail within N.S.F. parameters of 33 - 41°F, your pizza prep table is equipped
with a coldwall rail. The coldwall rail must maintain a freezing temperature so that
the pan product temperature can be maintained.
PIZZA RAIL SYSTEM SWITCH
A rail “On - Off” switch is located on the front grill so that the refrigeration can be
turned “On” to the rail during use and shut “Off” at the end of the day to save
energy and defrost the frost build up on the rail. Product should be removed
from the rail during the evening and stored in the refrigerated base. The rail
may need to be turned “Off” for periodic defrosting during the day if frost build
up becomes excessive. Product must not be left in the rail during this defrosting
period.
Important Note: Sandwich and pizza preparation tables are not intended for
overnight food storage in the top pan rail.
PIZZA PREP TEMP ADJUSTMENT - BOTTOM STORAGE COMPARTMENT
If an adjustment is necessary to maintain the average cabinet temperature range
of 38°F only, place a screwdriver into the thermostat slot (located inside of the
cabinet on the side of the evaporator coil fan housing) and turn clockwise for a
colder cabinet temperature or counterclockwise for a warmer cabinet temperature.
Further adjustments out of the factory design temperature range must be made
by a qualified refrigeration mechanic only.
15
Download from Www.Somanuals.com. All Manuals Search And Download.
PIZZA PREP TEMP ADJUSTMENT - COLDWALL RAIL
If an adjustment is necessary to maintain the coldwall rail temperature, a pressure
control is located behind the front grill which controls the compressor operation and
the temperature range of the rail. The factory recommended settings for this low
pressure control are the following:
CUT IN = 45#
DIFFERENTIAL = 20#
Before making any adjustments to the pressure control out of the factory design
temperature range, please consult factory or a qualified refrigeration mechanic.
UNDERCOUNTER REFRIGERATOR SYSTEM AND ADJUSTMENT
All self-contained undercounter refrigerators are designed and factory set to
maintain an average cabinet temperature of 38°F. The temperature control is
accessible inside of the cabinet product compartment, on the right back wall
next to the evaporator coil (see figure 7 for thermostat location). If an adjustment
is necessary to maintain the above temperature range only, place a screwdriver
into the thermostat slot and turn clockwise for a colder cabinet temperature or
counterclockwise for a warmer cabinet temperature. Further adjustments out of
the factory design temperature range must be made by a qualified refrigeration
mechanic only.
Important Note: All refrigerators are designed with an automatic, “off-cycle”
defrost system which means that defrosting occurs automatically when the
compressor is not operating during an off-cycle. Do not set the thermostat too
cold where the cabinet temperature will fall below 35°F because the evaporator
will become blocked by ice since the compressor off-cycle will be considerably
shortened. This will result in loss of food stored within the cabinet and require
service to defrost the evaporator and re-adjust the thermostat.
UNDERCOUNTER FREEZER SYSTEM AND ADJUSTMENT
All self-contained undercounter freezers are designed and factory set to maintain
an average cabinet temperature of 0°F. All freezers are designed for the purpose
of holding pre-frozen food and although they are capable of freezing small quantities
of fresh food, they are not to be used as fast or blast freezers. Do not attempt to
freeze bulk quantities of fresh foods. The temperature control is accessible inside
of the cabinet product compartment, on the right back wall next to the evaporator
coil (see figure 7 for thermostat location). If an adjustment is necessary to maintain
the above temperature range only, place a screwdriver into the thermostat slot and
turn clockwise for a colder cabinet temperature or counterclockwise for a warmer
cabinet temperature. Further adjustments out of the factory design temperature
range must be made by a qualified refrigeration mechanic only.

DEFROST OPERATION
All freezer models are equipped with an automatic, electric defrost system consisting
of an electric evaporator coil heater, evaporator drain pan heater, automatic electric
defrost time clock, and defrost high limit switch. The defrost system is time initiated
by the time clock and temperature terminated by the high limit switch. The time clock
is preset for three (3) defrost periods per day at eight (8) hour intervals and a fail safe
cut-off time of 20 minutes. Please note that defrost settings are not programmable.
The defrost time clock is located in front of the electrical console box in the rear
machine compartment of your freezer. If desired, to pre-set the initiation of the
defrost cycle to the time of day on the defrost time clock, turn the knob on the
center dial of timer face clockwise until the unit defrost cycle begins (compressor
and all fans will terminate). Defrost will begin at this same time every day at eight
(8) hour intervals. For example, if an 8:00 am defrost is desired, at 8:00 am turn
the defrost manual set knob to initiate defrost and a defrost cycle will start every
day at 8:00 am, 4:00 pm, 12:00 am. It will be necessary to reset the time of
defrost on the timer if the freezer is turned off or has loss of power.
EVAPORATOR ASSEMBLY
All sandwich units, undercounter refrigerators and freezers have an easily
accessible, easily serviceable, performance rated, forced-air evaporator assembly
which utilizes a plasticized fin coil for extended life. All models utilize a full length,
extra large evaporator coil with a uniquely directed air flow distribution which keeps
pan product and compartment product at uniformly constant temperatures. The
complete evaporator assembly is shown in figure 7.

INTERIOR ACCESSORIES
The standard interior accessory package that is supplied from the factory with your
new sandwich unit model consists of standard pilaster strips with pilaster clips (four
(4)clips per shelf), and one (1) epoxy coated shelf per section.
SHELVING INSTALLATION
Pilaster strips which support the shelving are secured to the cabinet walls with
special pilaster screws which allow the strips to be readily removed for cleaning
without the use of tools. Shelf clips are easily installed by inserting them into the
pilasters at the desired shelf location and shelf installation is as simple as placing
the shelf on the clips as shown in figure 8.
Important Note: When loading shelves with food product, allow space between
rows of product for proper air circulation, and do not load product to block back wall
above step (leave at least 2" of air space between product and back wall above step).

MAINTENANCE
PERIODIC CLEANING PROCEDURE
It is best to clean your refrigerator or freezer when the product load is at its
lowest level inside your cabinet. To clean the interior or exterior cabinet surfaces,
the following procedure should be followed:
1. Disconnect your model from its power supply and remove all food product
from inside.
2. Open all doors and allow the cabinet to reach room temperature. Remove
all accessories (shelves, racks, pilasters, clips, etc.) From within the model,
wash with a baking soda and warm water solution, and rinse thoroughly with
clear water. Dry all of the accessories completely with a soft clean cloth.
3. Once the cabinet has reached room temperature, wash the entire cabinet
inside and out with a baking soda and warm water solution. For slightly
more difficult cleanups, ammonia or vinegar in warm water can be used.
Rinse thoroughly with clear water and dry with a soft clean cloth. Failure
to dry all surfaces completely may cause water stains or streaking on the
aluminum or stainless steel finish.
4. Return all accessories to their respective positions and return electric supply
power to the model.

Precautions
1. Never use harsh detergents, cleaners, scouring powders, or chemicals when
cleaning your model.
2. Strong bleaches tend to corrode many materials and should never come in
contact with stainless steel.
3. Tincture of iodine, or iron should not come in contact with stainless steel.
These solutions, which cause stainless steel to discolor, should be rinsed off
immediately if contact occurs.
4. Some foods, such as mustard, mayonnaise, lemon juice, dressings or salts,
may attack or corrode stainless steel.
5. Gritty, hard abrasives will mar the finish of stainless steel and aluminum and
are not recommended.
GENERAL PREVENTATIVE MAINTENANCE
Performance of the air cooled condensing unit located inside of the compressor
machine compartment of your new model, depends exclusively upon the amount of
air passing through the condenser fins. Your refrigerator or freezer will run more
efficiently, consume less current, and provide a maximum of trouble-free service
throughout its lifetime if the condenser is kept clean and an adequate supply of
clean, cool air is provided at all times. Periodically (at least once a month) inspect
the condenser coil, which is located directly behind the rear panel grill, to check for
debris or blockage.
If the condenser coil is dirty or blocked, disconnect the power supply to your model
and using a stiff brush, brush the dirt from the condenser fins until the condenser is
clear from any debris. Using a vacuum cleaner with a brush attachment may aid in
this cleaning process. After cleaning, restore electrical service to your model.
PARTS AND SERVICE
Always provide the cabinet model and serial number (located on the data plate on the
inside right wall of the cabinet) whenever contacting the factory or your dealer regard-
ing questions or when ordering parts.

Warranty Compressor Procedures
If the compressor fails within the first (12) months of use or (20) months by the
date code on the compressor, an “over-the-counter exchange” must be made through
a Tecumseh or Copeland dealer.
After the first year the additional (4) year compressor warranty is through
Continental Refrigeration, and can be handled by one of the following methods:
(1)Continental will supply the replacement compressor at no charge and
pay for regular ground freight.
(2)Continental will supply the compressor at no charge and the end user,
dealer or service company pays for the freight, other than regular
ground (COD, Visa or Mastercard).
(3)A compressor can be purchased locally and Continental will either
replace the compressor for stock or offer an allowance towards its pur
chase. The end user is to pay the difference:

(C) 1 h.p. to 2 h.p.-Up to $350
Exceptions will be made depending on circumstances, but in all cases,
Continental must be notified prior to any transaction, if possible. The tag from the
defective compressor or the information (if unable to remove) must be returned for
proof of failure after the first year. Please contact the service department with any
further questions.
