RECEIVING YOUR NEW MODEL
Congratulations on your purchase of Continental Refrigerator
superior foodservice equipment! When your shipment arrives,
thoroughly examine the packaging 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
contents for any missing accessories, or concealed damage
which may have occurred during shipment. If the cabinet is
damaged, it must be noted on the 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 it and familiarize yourself with your equipment and
its operation, to enjoy optimum performance.
Continental Refrigerator offers a variety of accessories for your
model (see “Optional Accessories” section towards the back
of this manual or contact your dealer for more information).
SERIAL DATA TAG
A serialized data tag is permanently attached to the inside righthand wall of your unit. (see Figure 1). In addition to identifying
the specific product, this label provides important information
regarding electrical requirements and refrigeration charge, as
well as agency listings and factory contacts.
FIGURE 1: Data Tag
IMPORTANT NOTE: The model and serial number should
be noted on the front cover of this manual, in the spaces
provided. If parts or service are ever needed for your unit,
this information will be required to verify warranty status
and to properly identify any parts that may be needed.
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 (4°C). 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 (-18°C) (see “Operation” section for further
information).
Prior to factory shipping, all products are performance-run
tested for a minimum of 12 hours providing a highly sophisticated temperature recording exclusive to each individual
cabinet. This recording is supplied within this manual packet. A
final evaluation, including analysis of cabinet performance, leak
check, vibration, noise level and visual examination is made by a
qualified quality control team to assure a superior product. The
carrier signs to this effect when they accept the product for shipping. To insure the maximum in safety and sanitation, all models
are listed under the applicable of Underwriters Laboratories and
National Sanitation Foundation standards.
UNCRATING YOUR NEW MODEL
The shipping container should remain on your cabinet to protect against dents or scratches while transporting to the actual
set-up location. Remove the shipping container only at the last
possible moment by using a pry bar to take out all the staples
from around the bottom of the crate. Slide the cardboard carton
up and off the unit, being careful not to rub against the cabinet.
Remove any accessories or boxes on the skid or in the cabinet.
Four (4) bolts secure 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, tilt the cabinet backwards and place wooden
blocks at each end in order to hold it in its tilted position. Using
a ¾” 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.

WORKTOP/UNDERCOUNTERS & SANDWICH UNITS
IMPORTANT NOTE: Do not under any circumstances, lay
your new model on its front or sides. For a brief period
of time, you may lay the cabinet on its back, but only
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 damaging
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 this can damage the compressor.
INSTALLATION AND LOCATION
For optimum performance, “SW” series models should be
installed on casters or legs (see “Installing Casters” or
Installing Legs”) and a mini mum 3” clearance should be
provided on each side and the rear of the cabinet (see Figure
2). Your model has been designed to also 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
louvers and the rear wall (see Figure 2). Cabinet side clearance
is not required when mounting your model directly on the floor,
without legs or casters. If any of the above conditions can not be
achieved, the installer should provide special venting or air supply ducts, or a Front-Breather Kit (see “Optional Accessories”)
can be ordered by contacting the factory.
Before moving the cabinet to its final point of installation, measure all doorways or passages to assure clearance. If additional
clearance is needed, you can remove the cabinet doors (see
“Removal of Doors and Door Adjustment”) and lids (when
equipped) (see “Removing Lid and Hood”).
“UC” series models and units provided with the Front-Breather
Option do not require any clearance around the the sides or
back of the cabinet, since they take in and exhaust air under the
cabinet and through the front grill, under the door. The air flow
under the cabinet and through the front grill cannot be restricted.
(see “Front Breather Kit” under “Optional Accessories”).
VENTILATION
The final location site of your air cooled refrigerator or freezer
must provide a large quantity of cool, clean air. All refrigeration
systems operate most efficiently and trouble-free with cool,
dry air circulation. Avoid locations near heat and moisture
generating equipment including ovens, cooking ranges, fryers,
dishwashers, steam kettles, etc., or in direct sunlight (where
temperatures can exceed 100°F). 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 places an excessive heat load on the condensing unit and adversely effect its operation.
FIGURE 2: Minimum Clearance Dimensions for Optimum Conditions
IMPORTANT NOTE: To assure maximum operating effi-
ciency, your new cabinet should be located where an
unrestricted air supply can circulate underneath and
behind the cabinet. 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.

OPTIONAL CASTER SHIM
(Reference #CM1-2476)
CASTER
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. Keep in mind that all the weight is concentrated
at the caster or leg locations. A fully loaded reach-in model may
reach 2,000-3,000 pounds. To estimate the possible product
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 to obtain the product load weight.
For example, a 20 cubic foot refrigerator can hold approximately
700 pounds of product (35 x 20). Assuming the cabinet itself
weighs 300 pounds, the total combined weight of cabinet and
product is approximately 1000 pounds. Therefore, the floor in
this example must be able to support up to 1000 pounds.
INSTALLING CASTERS AND LEVELING
If your new unit is supplied with swivel casters, they will be
packed in the accessory box that came with your cabinet.
Casters should be installed only when the cabinet is close to
it’s final installation site. To install casters on your new model,
carefully tip the unit back and position (4) 2” thick wood blocks
underneath. Locate the large threaded holes on the bottom of
the cabinet and screw the threaded caster studs into the mounting holes, closest to the front of the unit. Repeat this procedure
by tilting the cabinet in the opposite direction and installing
the remaining casters. Make sure the casters are tightened
extremely well (see Figure 3b). If the casters are not installed
tightly, the cabinet will be unstable and may sway or rock, which
can damage the cabinet.
FIGURE 3a: Installing Casters
FIGURE 3b: Casters Must Be Tight to Cabinet Bottom
If the height of a caster needs to be raised, shims must be
installed under the casters which need leveling. Extra large
washers, available at most hardware or furniture stores, can be
used to shim casters, or contact the factory for caster shims.
Do not attempt to level casters by unscrewing them
from the cabinet and leaving them loose, as this will
cause damage to the cabinet and leg hole threads,
voiding all warranties.
IMPORTANT NOTE: It is extremely important that your
cabinet is perfectly level for proper operation. If it is not
level, the following adverse conditions may occur:
1. The door(s) will not be properly aligned and
consequently will not provide a good seal.
2. Your unit may run excessively.
3. An excessive amount of ice will accumulate inside
the cabinet, around the door opening(s) and on the
finned evaporator coil. If allowed to continue, ice will
eventually block the coil and the unit will fail. This
can result in the loss of all food stored in 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 LEGS AND LEVELING
Your new is supplied with adjustable legs for leveling purposes.
Each model has four leg mounting holes on the bottom of the
cabinet. Legs are packed in the accessory carton from which
they must be removed and installed on the cabinet bottom
(see Figure 3). In order to install the legs, carefully tip the
cabinet back, 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 “Installing Condensate Evaporator” under “Installation
and Location” section).
To assure your cabinet is level, all legs are equipped with bullettype leveling bolts. These bolts can be turned by hand or by
wrench, clockwise or counterclockwise to level the cabinet.
FIGURE 4: Leg Installation
CONDENSATE REMOVAL
No floor drains or plumbing connections are required since all
models use an automatic condensate water evaporating system
(see Figure 5). 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, or heavy pan loading, the amount of condensate water generated could overflow the pan. If this occurs,
the plastic drain tube from the cabinet can be diverted directly
to a floor drain, bypassing the condensate pan. Alternatively,
an optional electric condensate vaporizer may be purchased
as an accessory. An electric condensate vaporizer is also supplied with all remote models. To install the optional condensate
vaporizer, follow the steps for (“Installing Electric Condensate
Vaporizer” in the “Optional Accessories” section) towards the
back of this manual.

To remove the drawers from the cabinet, slide each drawer
out until it stops. Unhook the stop clip at the front of the left
and right-hand drawer slide (see Figure 7) by pushing the clip
forward and pressing down on the top back edge as shown.
Lift the drawer slightly as you pull it the rest of the way out.
The center member, with the wheels attached, will remain in
the cabinet. To remove a drawer center member for cleaning or
maintenance, pull it out and push up on the release lever at the
back, as shown.
To install a drawer, identify the correct parts and orient the
center members so the plastic clips are in the front and at the
top. Insert one of the center members into the front of the correct cabinet member (which is permanently attached to the
inside of the cabinet) and slide it in, until it stops. Push up on
the release lever (located toward the rear and top of the center
member) to allow the center member roll the rest of the way
into the cabinet member, in the “drawer closed” position. Repeat
for the opposite side center member. Pull each center member
out a few inches, press down on the rear of each stop clip, and
pull forward so the hook on the front of the clip rotates up, into
the “unlocked” position. Lift the drawer body into place, resting
the drawer members (the channels welded to the sides of the
drawers) on the front wheels of the center member, and slide
the drawer into the cabinet. Once the drawer goes in all the way
and slides smoothly, open it enough to access the stop clips.
Lift the back of each clip and push in at the front, so the hook
portion snaps into the “locked” position. The drawers are now

REMOVAL AND REPLACEMENT
OF HINGE MECHANISM
To remove the hinge mechanism from the door, remove the door
from the cabinet as explained previously. As shown in Figure 8,
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 1/8” 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.

WORKTOP/UNDERCOUNTERS & SANDWICH UNITS
INITIAL CLEANING PROCEDURE
Prior to start-up and before placing any product 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.
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”).
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 towards the back of this manual (see “Wiring
Diagrams” section).
IMPORTANT NOTE: The condensing unit supplied with
all self-contained models is designed to operate with a
Rrange of +/-10% of the voltage indicated on the cabinet
serial data plate. Full voltage of the correct rating, on an
isolated line, not affected by the operation of other electrical appliances, must be available to the refrigeration unit
at all times. Burnout of the compressor due to exceeding
high or low voltage limits is easily detected and will void
the factory warranty.
115 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115 volt models are provided with
a factory installed, UL approved power
cord and polarized plug. 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.
WARNING: ANY ALTERATIONS TO THIS CORD AND
PLUG COULD CAUSE AN ELECTRICAL HAZARD AND
WILL VOID THE FACTORY WARRANTY.
115/208-230 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115/208-230 volt models are provided with three (3) supply wires, which exit the electrical box located in the machine
compartment rear, next to the compressor. The cabinet circuitry
is 115 volts and the condensing unit operates on 208-230 volts.
A permanently connected, 3-wire (plus ground) power supply is
required, consisting of (2) hot conductors and (1) neutral wire,
plus (1) ground wire. The supply leads must be connected to
the appropriate leads from the cabinet and the supply ground
wire must be attached to the electrical box with a ground lug
to provide proper grounding of the metal cabinet and chassis.
All wiring and connections should only be made 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).
10
OPERATIONS MANUAL
Page 11
WORKTOP/UNDERCOUNTERS & SANDWICH UNITS
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 5-6 MINUTES BEFORE
TURNING THE UNIT BACK ON TO ALLOW THE SYSTEM
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 hookup should be performed by qualified refrigeration personnel of
a competent refrigeration company only (see “Remote Set-Up
and Installation Guidelines” under “Optional Accessories”).
cabinet product compartment, on the right back wall next to the
evaporator coil (see Figure 11). If an adjustment is necessary
to maintain temperature within the range noted above, 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 should only be made by a qualified
refrigeration mechanic.
IMPORTANT NOTE: Turning a thermostat fully counterclockwise turns the refrigeration compressor “off.”
EVAPORATOR ASSEMBLY
All 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 compartment
product at uniformly constant temperatures (see Figure 11).
FIGURE 11: Evaporator Assembly
OPERATION
All cabinets must be given sufficient time to reach normal operating temperature before placing any product inside cabinet.
Refrigerators are designed to maintain an ideal cabinet temperature of 38° to 40°F (3.3° to 4.4°C), approximately 1 hour
of operation is required to reach this temperature. During pulldown 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 -4° to 0°F (-20° to -18°C), approximately
2 hours of operation are required to reach this temperature.
THERMOMETER CALIBRATION
Your new model has a non adjustable hanging thermometer
located inside the cabinet, mounted on the coil housing cover
(see Figure 11). This thermometer is maintenance-free and
needs no further calibration.
REFRIGERATION SYSTEM AND ADJUSTMENT
All self-contained refrigerators are designed and factory set to
maintain an average cabinet temperature of 38° to 40°F (3.3°
to 4.4°C). The temperature control is accessible inside of the
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 (1.7°C) because the evaporator will become blocked
by ice since the compressor off-cycle will be considerably
shortened. This will result in loss of product stored within
the cabinet and require service to defrost the evaporator
and re-adjust the thermostat.

FREEZER SYSTEM AND ADJUSTMENT
All self-contained sandwich unit freezers are designed and factory set to maintain an average cabinet temperature of -4° to
0°F (-20° to -18°C). All freezers are designed for the purpose
of holding pre-frozen product and although they are capable of
freezing small quantities of fresh product, they are not designed
to be blast chillers or ice-cream freezers. Do not attempt to freeze
bulk quantities of fresh food or ice-cream. The temperature control is accessible inside of the cabinet product compartment, on
the right back wall next to the evaporator coil (see Figure 11 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: Turning a thermostat fully counterclockwise turns the refrigeration compressor “off.”
DEFROST OPERATION
All freezer models are equipped with an automatic, electric
defrost system consisting of electric evaporator coil and drain
pan heaters, a defrost time clock and an automatic defrost limit
switch. The defrost system is time initiated by the time clock and
temperature terminated by the automatic 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.
FIGURE 12: Defrost Timer
INTERIOR ACCESSORIES
Your new unit is shipped with (1) shelf per section and (4) pilaster clips for each shelf.
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 (see Figure 13).
FIGURE 13: Standard Shelf Pilaster
The defrost time clock is located in front of the electrical console box in the rear machine compartment of your freezer (see
Figure 12). 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.

SAFETY PRECAUTIONS
THE FOLLOWING SAFEGUARDS SHOULD BE FOLLOWED
WHEN OPERATING ANY APPLIANCES: DISCONNECT
THE POWER CORD BEFORE ATTEMPTING TO WORK ON
OR CLEAN EQUIPMENT. DISCONNECT POWER WHEN
THE APPLIANCE WILL BE IDLE FOR A LONG PERIOD OF
TIME. DO NOT ATTEMPT TO REMOVE ANY COVERS OR
PARTS YOURSELF, AS THIS CAN EXPOSE DANGEROUS,
HIGH VOLTAGE WIRING. SERVICE SHOULD ONLY
BE PERFORMED BY A QUALIFIED TECHNICAIN.
ALWAYS ROUTE POWER CORDS AWAY FROM AREAS
WHERE THEY CAN BE WALKED ON OR DAMAGED BY
OTHER EQUIPMENT. NEVER USE EXTENSION CORDS
OR PLUG MORE THAN ONE APPLIANCE INTO THE
SAME CIRCUIT. THIS CAN OVERLOAD THE POWER
SUPPLY, WHICH CAN RESULT IN ELECTRICAL SHOCK
OR FIRE. YOUR APPLIANCE IS EQUIPPED WITH A
POLARIZED, GROUNDED POWER PLUG. NEVER
ATTEMPT TO REMOVE THE GROUND POST OR USE
A NON-POLARIZED ADAPTER, WITHOUT PROPERLY
GROUNDING THE EQUIPMENT. IF A REPLACEMENT
PART IS REQUIRED, ALWAYS INSIST ON FACTORY
AUTHORIZED COMPONENTS.
PERIODIC CLEANING PROCEDURE
It is best to clean your refrigerator or freezer when the product
load in your cabinet is as its lowest level. To clean the interior or
exterior cabinet surfaces, follow these procedures:
1. Disconnect your model from its power supply and remove
all product from inside.
2. Open all doors and allow the cabinet to reach room temp-
erature. 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
inside and outside with a solution of warm water and bak ing soda. 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
NEVER USE HARSH DETERGENTS, CLEANERS,
SCOURING POWDERS, OR CHEMICALS WHEN
CLEANING YOUR UNIT. STRONG BLEACHES TEND TO
CORRODE MANY MATERIALS AND SHOULD NEVER
COME IN CONTACT WITH STAINLESS STEEL. 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.
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 (see Figure 14).
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.

INSTALLING OVERSHELF OR DOUBLE-OVERSHELF
IMPORTANT NOTE: Installing an overshelf is a two-per-
son job. Due to the weight, size and height of the shelf, do
not attempt to mount it alone, as this can cause injury.
To mount an overshelf to your cabinet, a phillips-head screwdriver (or a screw gun with phillips bit) is required. Before
starting to assemble the overshelf, identify the following parts
provided: ¼-20 screws, 10-32 screw, uprights, top shelf, and
bottom shelf (for double overshelves only). If applicable, determine the height you want the bottom to be located.
IMPORTANT NOTE: There are three pairs of holes provided in the iprights, so the shelf can be installed at a
height of 19”, 21”, or 23” above the top of the cabinet.
This height will also determine the distance between the
bottom shelf and the top shelf (13”, 15”, or 17”).
10-32 screws on each end. Drive the screws until snug, but do
not tighten them completely.
With one person supporting each end of the top shelf, list it
into position above the uprights and lower it down onto them.
Secure the shelf, using two 10-32 screws on each end, driving
them snugly but not tightly. Check the alignment of the shelves
and tighten all the screws. Double check that the shelves and
uprights are secured rigidly.
FIGURE 15: Overshelf Installation
From the back of your cabinet, locate the two holes with threaded inserts at each end of the Cabinet. (see Figure 15) Drive a
¼-20 screw into each of the (4) threaded inserts, until the bottom of the screw head is about ” away from the threaded insert.
Position the uprights at the back of the cabinet. Noting that
there are two keyhole slots on one face of each upright, locate
the keyholes at the bottom, facing the screws you just installed
in the cabinet. Lift the upright and place the large portion of
the keyhole slots over the screw heads and then lower it on to
the screws. Insert a philips screwdriver through the clearance
holes, on the opposite side of the keyhole slots (in the rear of
the uprights). Tighten the screws just until the upright is snug
against the unit, but leave a little play for alignment. Repeat this
procedure for the other upright.
To install a double overshelf (for single overshelf, skip to the
next paragraph) locate the bottom shelf, which has a large hole
in each rear corner. With one person holding each end of the
shelf, lift it above the top of the uprights and align it so the
large holes in the rear of the shelf fit over the uprights. Carefully
slide the shelf down, until the small holes on back of the shelf
line up with the correct holes in the uprights, depending on the
shelf height desired. Attach the shelf to the uprights, using two
INSTALLING STACKING COLLAR ADAPTER KIT
All models that are 48” wide or less and have a solid, flat top
can be stacked one on top of the other with the use of a heavy
duty, stainless steel stacking collar as shown in Figure 16. When
stacking a refrigerator and freezer, it is always best to place the
freezer model on the bottom for maximum efficiency. The front
grill which is attached to the stacking collar body is attached
with easily removable thumbscrews and should be removed
periodically for cleaning. The front grill should always be clean
and clear of debris and never blocked.
To stack your models, the following instructions should be followed:
1. Decide which unit is to be on “top” & “bottom”.
2. On “top” unit, remove screws at the bottom of the back
cover. In “bottom” unit, remove screws, joggle clips and
bumpers aloing the top back of the cabinet.

3. Install the legs on the “top” unit and adjust all four bullet
feet out (CCW) three full turns. Carefully lift the cabinet and
set it on top of the “bottom” unit.
4. Install stacking collar as shown in Figure 16, making sure
all rear screw hole slots line up on both top and bottom
models where screws were removed from in Step 2. If
screw hole slots do not line up (left to right) with screw
holes then the stacking collar has been mounted upside
down. Remove and re-install correctly.
5. Adjust the height and level of the “top” cabinet by reaching
in through the front opening of the stacking collar and turn ing the bullet feet on the legs in (CW) until the bottom of
the cabinet is snug against the stacking collar. Once snug,
install the rear screws that were removed in Step 2 and
peel off the adhesive tape backing strip around the side
flanges of the stacking collar so that both units are bonded
together.
6. Align the front grill holes with the stacking collar holes and
secure both thumbscrews.

INSTALLING FRONT BREATHER KIT (Skirt and Grill)
IMPORTANT NOTE: You may CAREFULLY lay the cabinet
on it’s back, but only FOR A BRIEF PERIOD OF TIME.
Caution must be taken to ensure you DO NOT DAMAGE
the louvered back panel, refrigeration system components, or copper tubing located behind the panel. The
cabinet must be properly blocked, to allow room to get
your hands in to lift without damaging the cabinet or
crushing the vents on the back panel. DO NOT PLUG-IN
OR OPERATE THE REFRIGERATION SYSTEM FOR AT
LEAST THREE (3) HOURS AFTER THE UNIT HAS BEEN
RETURNING IT TO AN UPRIGHT POSITION, AS THIS
CAN DAMAGE THE COMPRESSOR.
Position the left hand air duct/skirt (see Figure 17) as shown.
Attach the front left caster by inserting threaded end through the
slot in the air duct/skirt and screwing it into the threaded hole in
the bottom of the cabinet. Do not tighten completely. Repeat for
the back left caster. Follow these steps for the right hand air/duct
skirt and remaining casters. Position the front grill as shown
and attach it to the front edge of the air duct/skirts using the
thumbscrews provided. Adjust the position of the air duct/skirts
and the front grill as needed. Tighten the thumbscrews and all 4
casters completely. Carefully lift the cabinet upright and check
that the grill and casters are secure.
Your refrigerator or freezer is now front breathing and can be
completely enclosed on the sides, back and top. The refrigeration system will take in fresh air through one side of the front
grill, pull it under the cabinet, through compressor compartment
to cool the condenser, back out under the cabinet and exhaust it
through the other side of the front grill.
ANY RESTRICTIONS TO THE AIR FLOW THROUGH THE
FRONT GRILL OR UNDER THE CABINET CAN DAMAGE
THE REFRIGERATION SYSTEM AND WILL VOID ALL
WARRANTIES.

(or drill/driver with Phillips bit), and a rubber mallet. Take the
door off the section you want to convert, by following instructions in the “Removal of Doors” section of this manual. Take the
drawers out of the mounting cage, by following instructions in
the “Removal of Drawers” section of this manual.
ing the front of the cage to the inside of the opening, and tighten
them snugly, without stripping the screws or the pilot holes.
Drive a sheet metal screw through each of the two slots located
at the lower the rear of the cage and into the back wall step of
the Cabinet.
IMPORTANT NOTE: These screws should NOT be tight!
The purpose of these screws is to limit the side-to-side
movement of the rear of the cage, not to rigidly secure the
cage to the cabinet.
To re-install the drawers into the cabinet, follow the instructions
in the “Removal of Drawers” section of this manual. Note that
the top drawer slides are longer than the bottom slides.
FIGURE 18: Drawer Cage
Position the drawer mounting cage in front of the cabinet opening as shown (see Figure 18). Lift the cage above the trim along
the bottom of the opening, so it is aligned to go straight into the
cabinet. Carefully slide the drawer cage into the unit opening. It
is a snug fit and some pressure may be need to be applied at
the corners, to clear the breaker around the opening. A rubber
mallet can be used to gently tap on the ends of the drawer cage
cross mullion, to force the fasteners past the side breakers. The
straighter the cage is pushed in, the easier it will be to install.
When the cage is in as far as it will go, the notches at the front
of the cage should surround the breaker corners at the bottom.
The face of the drawer cross mullion should be relatively flush
with the front face of the cabinet, to provide an even surface for
the drawer gaskets to seal properly around the openings. The
cage should sit relatively flat on the floor and against the back
wall step inside the cabinet.
With the cage properly in place, use the holes along the front
sides of the cage assembly as a template to drill (6) 1/8” pilot
holes through side breakers and the metal underneath. Drive a
sheet metal screw into each of the front mounting holes, secur-
MOUNTING CASTER SUPPORT PLATES
If the standard stem casters on a cabinet are not properly maintained and tightened, or if the unit is excessively overloaded and
moved around, the threaded inserts in the bottom of the cabinet
can become stripped, twisted or collapsed. If this occurs and
the stem casters cannot be mounted securely, rigid caster support plates can be fitted to provide the strength needed to safely
use your cabinet. Each caster support plate assembly is made
of heavy gauge galvanized steel, with (2) casters permanently
welded to it, for maximum rigidity. The plate has a series of
holes that will allow you to fasten the plate assembly to the bottom of the cabinet with sheet metal screws and bolts. Contact
the factory to obtain the correct parts for your model.

To install caster support plate assemblies, you will need a 3/4”
open end wrench (or a large adjustable wrench), a drill with a
1/8” bit and a Phillips bit (or a Phillips-Head screwdriver) plus
work gloves. A 1/2-13 thread tap is also recommended, to repair
any damage to the threaded inserts in the cabinet. Unload all
product and carefully lay the cabinet on its back. Remove the old
stem casters by unscrewing them from the cabinet. If a caster or
threaded insert has been stripped or cross-threaded, it may be
necessary to use a wrench to loosen the caster.
system back on, and at least another 30 minutes for the cabinet
to come down to temperature and stabilize, before reloading
with product.
FIGURE 19: Caster Support Plates
Hold one of the support plate assemblies under the cabinet as
shown (see Figure 19). Position it so the slotted holes at the end
of the plate line up with the threaded inserts in the bottom of the
cabinet (where the stem casters were attached). Attach the plate
assembly to the cabinet by putting a 1/2” x 1-3/4” long bolts and
flat washer through the slot in the support plate and screwing
into each of the threaded inserts in the bottom of the cabinet.
Snug the bolts down, but do not tighten them completely. If
one of the threaded inserts is stripped or damaged, a thread tap
should be used to clean the threads.
Using the small holes in the plate as a template, drill 1/8 pilot
holes in the bottom of the cabinet. (Note: drill only until you
penetrate the metal bottom of the cabinet. Do not continue
to drill into the insulation, or you may damage the cabinet.)
Secure the caster support plate assembly to the cabinet with a
sheet metal screw in each of the drilled holes. Tighten the 1/2”
bolts. Repeat these steps to attach the other plate assembly to
the opposite end of the cabinet.
Check that both plates are secure and that the casters turn
and swivel freely. Carefully lift the cabinet upright and double
check that the caster support plates are secure and the cabinet
is stable. Wait at least 3 hours before turning the refrigeration
INSTALLING ELECTRIC CONDENSATE VAPORIZER
The electric condensate vaporizer has a power cord attached and
is provided with a mounting bracket and two hold-down clips. To
install the vaporizer, remove the screws securing the back cover
to the cabinet (see Figure 20) and set the cover aside. Remove
the old drain pan and install the vaporizer mounting bracket on
the rail next to the compressor. Slide the vaporizer pan onto
the bracket and carefully place the end of the plastic drain tube
into the pan. Make sure the tubing is not blocked or kinked and
that the end is located securely, so any water running out of the
tube will go into the pan. Secure the pan with the clips provided
and plug the power cord into the receptacle labeled “Vaporizer”
on the lower back wall of the cabinet. Secure any excess power
cord with a wire tie, so it does not fall into the pan or under the
cabinet. Reattach the cover to the back of the cabinet.
IMPORTANT NOTE: It is extremely important to ensure
the condensate pan is plugged into the receptacle labeled
“vaporizer” and that the condensing unit is plugged into
the receptacle labeled “condensing unit.”

REMOTE SET-UP AND INSTALLATION GUIDELINES
All remote refrigerators and freezers are shipped with an expansion valve, thermostat and defrost timer (freezer only), installed
from the factory. The installer is responsible for connecting all
refrigerant lines, liquid line drier, sight glass, solenoid, head
pressure control, hi/low pressure safety, crankcase heater, condensing unit and any other accessories as well as wiring. The
evaporator section has been factory leak checked with helium,
however; due to vibration in transit, the entire system must be
thoroughly leak checked after installation and prior to start-up.
The final leak inspection of the entire completed refrigeration
system and all of its components as well as start-up and the
operation of the refrigeration system is the sole responsibility
of the installer.
All refrigerant lines and components must be clean, free of 1.
burrs and purged with nitrogen prior to and during brazing
or soldering connections. Nitrogen purging during brazing or soldering will eliminate carbon or foreign matter
contamination. Any system restrictions or contamination is
the responsibility of the installer.
Condensing unit or compressor shall not be left open to 2.
the atmosphere for more than five (5) minutes.
No refrigeration component, tubing or fitting shall be left 3.
open to the atmosphere for more than ½ hour without
being soldered, capped or plugged.
Each completed refrigeration system shall be purged with 4.
150psi of dry nitrogen for at least six (6) seconds, then
pressurized with at least 165psi of nitrogen for pressure
check (making sure to energize any solenoid valves to
assure access). Leak-check all joints, flare fittings and
valves and make sure there is no pressure drop within the
system.
System evacuation is of the utmost importance with NON-5.
CFC refrigerant systems. System must be evacuated to a
minimum of 200 microns. In addition, a vacuum decay
test is strongly recommended to assure there is not a
large pressure differential between the system and the
vacuum pump. System must be evacuated from both high
and low sides of the system using heavy duty vacuum
hoses.
Each system should be charged with the refrigerant type 6.
as specified on the cabinet data tag. This refrigerant type
should match the type listed on the condensing unit being
used. The refrigerant charge should be held to the minimum required for the satisfactory pull down and operation. For an accurate indication of refrigerant charge, the
sight glass will show a full column of liquid.
The superheat reading taken 6” from the compressor suc-7.
tion valve should be 30° +/- 5°. Expansion valve adjustment may be necessary to achieve this superheat.
Installation of the electric condensate vaporizer is also 8.
the responsibility of the installer (see “Installing Electric
Condensate Vaporizer” under “optional Accessories”).
The CFC-Free refrigerant used in standard remote and self-contained models is R-134a for refrigerators and R-404a for freezers. All compressors and systems designed for these refrigerant
utilize polyolester oil as their main lubricant, which absorbs
moisture from the ambient surroundings extremely fast and
in much greater quantity than conventional mineral oils. Since
moisture levels greater than 100 PPM will result in system corrosion and ultimate failure, it is imperative that the compressor,
components and entire system be kept sealed.
CAUTION: EXTREME CARE MUST BE USED WHEN
ACCESSING THE SYSTEM DURING INSTALLATION. DUE
TO THE COMPLEXITY OF REMOTE REFRIGERATION
SYSTEMS AND THE POTENTIAL FOR IMPROPER
INSTALLATION, ANY RESTRICTIONS, LEAKS, FAILED OR
DAMAGED COMPONENTS CAUSED BY CONTAMINANTS
ARE NOT THE RESPONSIBILITY OF CONTINENTAL
