WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS 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 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
and a Freight Claim must be filed with the shipping company.
FREIGHT DAMAGE IS NOT COVERED UNDER WARRANTY.
GENERAL INFORMATION AND
IMPORTANT OPERATING FACTS
This manual has been compiled to aid in the installation, operation and maintenance of your equipment. Please read it and
familiarize yourself with your equipment, its operation and available accessories, to enjoy optimum performance.
This equipment is prohibited from use in California with
any refrigerants on the “List of Prohibited Substances” for
that specific end-use, in accordance with California Code of
Regulations, title 17, section 95374. This disclosure statement
has been reviewed and approved by NRAC, Inc. and NRAC, Inc.
attests, under penalty of perjury, that these statements are true
and accurate.
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 applicable Underwriters Laboratories
and National Sanitation Foundation standards.
CAUTION
RISK OF ELECTRICAL SHOCK
KEEP ELECTRICAL COMPONENTS AND CONTROLS DRY
- DO NOT SPRAY WITH WATER!
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN
CAUSE A HAZARD & VOID FACTORY WARRANTY.
UNCRATING YOUR NEW MODEL
IMPORTANT: Your equipment should never be transported on legs/casters unless the cabinet bottom is properly
supported. Consult the factory for more information.
The shipping container should remain on your cabinet to avoid
dents or scratches while transporting to the actual set-up location. All shelving, accessories and legs or casters are carefully
packaged and secured inside your cabinet to prevent damage.
After moving unit to its final location, remove all the staples
from around the bottom of the crate using a pry bar. 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. Dispose of all packaging materials properly.
OPERATIONS MANUAL
5
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS 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 cabinet 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. 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
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”).
VENTILATION
The final location site of your air cooled refrigerator or freezer
must provide a sufficient quantity of cool, clean air. All refrigeration systems operate more efficiently and trouble-free with cool,
dry air circulation. Avoid locations near heat and moisture generating equipment including ovens, fryers, dishwashers, steam
kettles, etc. Do not install in direct sunlight (where temperatures
may exceed 100°F) or in an unheated area (where temperatures
may drop below 55°F).
Air supply to the condensing unit is critical. Restricting airflow
places excessive heat load on the unit, adversely affecting its
operation and may cause premature failure. The condenser coil
must be kept clean and free from obstruction. Condenser air filters are not recommended, since they hinder airflow, especially
if they are not replaced frequently. Contact our factory Service
Department for more information.
For optimum performance, all models should be installed on
casters or legs (see “Installing Casters” or “Legs”) with a
minimum 3” on each side and back of cabinet (see Figure 2).
This spacing will provide sufficient room for proper air circulation and clearance to access components for cleaning and
maintenance. If any of the these conditions cannot be met, the
installer should provide special venting or air ducts, as required.
Your model has also 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
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.
FIGURE 2: Minimum Clearance Dimensions for Optimum Conditions

OPERATIONS MANUAL
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS “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”).
IMPORTANT NOTE: For maximum efficiency, your new
cabinet must be located where an unrestricted air supply
can circulate above and behind it. Never obstruct the face
of the condenser or the grill area in the front of the cabinet and never place or store anything inside the cabinet
machine compartment. These rules are essential for long
life. FAILURE TO FOLLOW THESE GUIDELINES MAY
VOID YOUR WARRANTY.
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.
FIGURE 3: Installing Casters
OPTIONAL CASTER SHIM
(Reference #CM1-2476)
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.
CASTER
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 3). If the casters are not installed
tightly, the cabinet will be unstable and may sway or rock, which
can damage the cabinet.
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.

WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS INSTALLING LEGS AND LEVELING
If your new unit is supplied with adjustable legs, they will be
packed in the accessory carton in the cabinet. Each model has
four leg mounting holes on the bottom of the cabinet (see
Figure 4). 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.

END
eliminate water as quickly as possible. The wick has a special
antimicrobial coating which minimizes any potential growth of
mold or bacteria. The wick pad should be replaced once a year,
or if it ever appears clogged or will not retain its shape.
In some adverse conditions such as extreme ambient temperature, high humidity, exceptionally heavy usage, frequent loading
for prolonged periods of time, or extra 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 heater may be
purchased as an accessory. To install the optional condensate
heater, follow the steps for: “Installing Electric Condensate
Heater” in the “Optional Accessories” section, located at the
back of this manual. (Note: An electric condensate heater is
supplied standard on all remote models.)
Periodically (at least once a month) the condenser coil should
be inspected, to make sure it is not dirty or blocked, and the
wick pad can be easily checked at the same time. To check
the condenser and wick, disconnect the cabinet power supply,
remove the screws securing the back cover to the cabinet and
set the parts aside. Inspect the condenser coil and wick pad
for any damage or debris. Make sure the wick is secured in the
drain pan as shown. Remove any mineral deposits or dirt buildup on the condenser, as well as on the wick pad and drain pan.
Reattach the back cover and reconnect power to the cabinet.
Contact the factory if you need to order a new wick pad or any
replacement parts.

CONDENSATE REMOVAL
During the refrigeration process, warm, air is cooled and moisture condenses into water which collects in a drain pan in your
cabinet. No floor drains or plumbing connections are required
for your cabinet, since all models use a self-contained, automatic condensate water evaporating system (see Figure 5).
Some models include a wick pad in the drain pan, to maximize
evaporation. The pad is made of a composite wicking material
with a metallic facing, specifically designed to safely absorb and

HINGE TENSION ADJUSTMENT
The self-closing doors on your unit have a spring-loaded hinge
cartridge concealed in the door (see Figure 7) with a hold-open
feature and a cushioned stop. When the door is fully opened
(115°) the hinge should be tensionfree. When the door is moved
between the open and closed position, the spring-loaded hinge
will automatically rotate the door toward the closed position. For
proper operation, self-closing doors must be installed with the
spring-loaded hinge mechanism set to apply tension in the
proper direction (see Figure 8).
To adjust spring tension, Open the door fully (115°) so it stays
in position when released. Remove the mounting screws securing the cartridge bracket to the cabinet (see Figure 6). The
bracket should stay in position when released, but if it is moved
or bumped, it may snap into the closed position.
THE HINGE CARTRIDGE IS SPRING LOADED AND MAY
SNAP BACK ON FINGERS WHEN BRACKET IS LOOSE.
WEAR WORK GLOVES AND USE CAUTION WHEN
REMOVING MOUNTING SCREWS!!
REMOVAL AND REPLACEMENT OF DOORS
If you need to remove a door from your cabinet, first identify
the location of the spring-loaded hinge cartridge (see Figure 8).
Depending on the age of your cabinet, the cartridge is located
either on the top or the bottom of the door.
CAUTION: THE HINGE CARTRIDGE IS SPRING LOADED
AND THE BRACKET MAY SNAP TOWARDS THE DOOR!
For doors with spring cartridge on the top: Open the door fully
(115°) and remove the mounting screws (see Figure 6) securing the hinge cartridge bracket to the cabinet above the door.
(The bracket should stay in the open position, but if it is moved
it may snap closed). Pick the door straight up, being careful not
to bump the cartridge bracket, and lift it off the pivot pin bracket
below the door. To reinstall a door, reverse this procedure and
follow the instructions above to set the hinge tension and adjust
the door properly.

SANDWICH TOP AND FOOD PANS
Sandwich units are provided with food pans and divider bars. All
pans must be kept in place whenever your unit is operating and
lids should be closed whenever possible for optimum performance. To remove the lid over the pans (see Figure 9), lift it 1/2
way up and carefully push in on one end at the bottom corner,
so the pivot pin comes out of the mating hole in the hood. Swing
the end of the lid forward, so it clears the end of the hood. Slide
the entire lid sideways, so the pivot pin on the opposite end is
free from the hood. If you have an insulated lid, to remove the
liner and insulation, take out the screws along the back edge, let
the back of the liner drop down and rotate it so the front edge
of the liner disengages from the front of the lid. To remove the
hood from the cabinet, take out the screws located inside each
end and along the back edge.

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. Remove the protective film (which is clear on some
models) from all interior sides, bottom and other internal metal
panels, by working the corner loose and slowly pulling the film
back. 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). Wipe down thoroughly with
a damp cloth or sponge that has been soaked in clean water and
wrung out thoroughly, 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 within a
range 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.
GFI/GFCI RECEPTACLES
Ground-Fault Circuit Interrupter (GFCI or GFI) devices are not
recommended for most commercial refrigerators and freezers,
since nuisance trips may occur, typically due to moisture. This
can cause temporary loss of power, which may result in high
storage temperatures and potentially unsafe food product.
Building codes in some areas may require certain 115 volt
receptacles to be protected by a GFI. If you need to connect your
equipment to a protected circuit, a properly sized, commercial
grade GFI circuit breaker should be used on a separate, isolated
power supply. Or a qualified electrician may be able to hard wire
your equipment, eliminating the need for a GFI device. Contact
Continental’s Service Department before making any modifications to your cabinet, to avoid loss of warranty.

OPERATION WITH MECHANICAL THERMOSTAT
All cabinets must be given sufficient time to reach normal
operating temperature before placing any product in cabinet.
Refrigerators are designed to maintain cabinet temperature
of 38° to 40°F (3.3° to 4.4°C), about 1 hour of operation is
required to reach this temperature. Food pans in sandwich tops
must be kept in place at all times and lids should be kept closed
whenever possible. Freezers are designed to maintain an ideal
cabinet temperature of -4° to 0°F (-20° to -18°C), about 2 hours
of operation is required to reach temperature.
THERMOMETER
Your new model has a non adjustable hanging thermometer
located inside the cabinet, mounted on the coil housing cover
(see Figure 10). 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
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.
OPERATIONS MANUAL
IMPORTANT NOTE: Turning a thermostat fully counterclockwise turns the refrigeration compressor “off.”
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS 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 (Sandwich)
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.
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.
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.

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

PERIODIC CLEANING PROCEDURE
It is always 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 cabinet from its power supply and remove
all product from inside.
2. Open all doors and allow the cabinet to reach room temperature. Remove all accessories (shelves, pilasters, clips,
etc.) from inside and wash them with a baking soda
and warm water solution, wipe thoroughly with clean water.
Dry all accessories completely with a soft clean cloth.
3. Once the cabinet has reached room temperature, wash the
inside and outside surfaces with a solution of warm water
and baking soda. Pay particular attention to the face of the
cabinet, as any residue or debris can impair the door seal.
For slightly more difficult cleanups, ammonia or vinegar in
warm water can be used. Wipe down thoroughly with a
damp cloth or sponge that has been soaked in clean water
and wrung out thoroughly, and dry with a clean, soft cloth.

GENERAL PREVENTATIVE MAINTENANCE
The most important thing you can do to maintain any refrigerator or freezer and extend its life, is to keep the condenser clean.
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 energy, and provide a maximum of
trouble-free service throughout its lifetime if the condenser
coil is kept clean and an adequate supply of clean, cool air is
provided at all times. Periodically (at least once a month) it is
important to inspect the condenser coil for any debris or blockage that may have accumulated (see Figure 5).
If the condenser coil is dirty or dusty, disconnect the cabinet
power supply and use a stiff brush to wipe away any dirt and
debris from the condenser fins. Using a vacuum cleaner with a
brush attachment may aid in this process. After cleaning, restore
electrical service to your cabinet.
OPERATIONS MANUAL
IMPORTANT!
AFTER-MARKET CONDENSER FILTERS ARE NOT
PERMITTED BECAUSE THEY HINDER AIRFLOW.
FAILURE TO KEEP THE CONDENSER CLEAN AND
FREE FROM OBSTRUCTIONS WILL CAUSE EXCESSIVE
COMPRESSOR LOAD, REDUCING THE PERFORMANCE
OF YOUR UNIT. THIS CAN RESULT IN PREMATURE
FAILURE AND WILL VOID YOUR WARRANTY.
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS CARE AND CLEANING OF STAINLESS STEEL*
DO NOT USE: abrasive
cleaners, chemicals with
chlorides or muriatic
acid to clean your
equipment.
*Some information and graphics for this section were obtained from “Stainless
Steel Equipment Care and Cleaning” brochure, published by the North American
Association of Food Equipment Manufacturers (NAFEM).
Contrary to popular beliefs, stainless steel can rust, if not properly cared for and maintained (That’s why it’s called stain-LESS
steel, not stain-PROOF steel.)
All steel is primarily made of
iron. Stainless steels contain
other metals, such as chromium and nickel, that provide an
invisible film on the surface of
the steel that acts as a shield
against corrosion. As long as
this invisible layer is intact and
not broken or contaminated,
the metal will retain its corrosion protection and remain
stain-less.
3. HARD WATER causes spots and stains on stainless steel
surfaces, particularly when it is heated. Find out the hardness of your water and treat it properly, if needed. Use a
water filter and softeners if you have hard water. Club soda
can be used to remove streaks or spots.
There are 3 basic things that can break down the protective
layer on your stainless steel, which must be avoided:
1. MECHANICAL ABRASION is caused by things that
scratch the surface of the metal. Only use soft cloths or
plastic scouring pads to clean and always scrub in the
same directions as the metal grain.
DO NOT USE: hot or hard water to clean stainless steel.
CLEAN YOUR STAINLESS STEEL REGULARLY using the proper
tools and cleaners. After cleaning, always wipe, wipe, wipe
thoroughly with cool, clean, clear water.
DO NOT USE: abrasive cleaners, steel pads, wire
brushes, scrapers or knives to clean your equipment.
2. CHLORIDES are found in water, salt, food and worst
of all, many cleaners. Only use chloride-free, alkalinebased, non-abrasive cleaners. Always wipe thoroughly
with cool, clean water and dry with a soft towel. A solution of 1 tablespoon baking soda mixed with 1 pint water
can be used to remove tough stains.
CHECK ALL OF YOUR EQUIPMENT PERIODICALLY. If you see
any signs of rust, clean the area immediately, with a plastic
scrubbing pad. If surface rust is removed promptly, permanent
corrosion, pits and cracks may be avoided. Special stainless
steel polishes, that can help restore the protective coating on
your equipment, are available from a variety of retailers.
IMPORTANT: If these recommendations are not followed,
the protective film on your stainless steel can break down
and your equipment may begin the long walk down the
dark road of corrosion.

INSTALLING DRAWER CAGE
To convert your cabinet from doors to drawers, you will need a
drill with a 1/8” bit, a Phillips bit (or a Phillips-Head screwdriver
(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.
Position the drawer mounting cage in front of the cabinet opening as shown (see Figure 14). 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.
OPERATIONS MANUAL
19
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS 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, securing 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.
INSTALLING OVERSHELF OR DOUBLE-OVERSHELF
IMPORTANT NOTE: Installing an overshelf is a two-person 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 uprights so the bottom shelf can be installed at
a height of 19”, 21”, or 23” above the top of the cabinet.
On double overshelves, this height will also determine
the distance between the bottom shelf and the top shelf
(13”, 15”, or 17”).
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.

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
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.
20
OPERATIONS MANUAL
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS 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

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 turning 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.

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.

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

lag bolts and secure secure plate casters as shown.
FIGURE 17A: Front Breather Divider Kit (2’ high)
FRONT BREATHER DUCT KIT (3” high)
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.

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.
OPERATIONS MANUAL
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS IMPORTANT NOTE: Always wear proper work gloves and
use appropriate safety equipment. 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

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.
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.
Hold one of the support plate assemblies under the cabinet as
shown (see Figure 18). 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 the caster support plates are secure and the cabinet
is stable. Wait at least 3 hours before turning the refrigeration
system back on, and at least another 30 minutes for the cabinet
to come down to temperature and stabilize, before reloading
with product.
INSTALLING ELECTRIC CONDENSATE HEATER
The electric condensate heater has a thermal limit switch and
power cord attached. To install the heater, remove the screws
securing the back cover to the cabinet (see Figure 19) and set
the cover aside. Place the vaporizer heater in the drain pan as
shown and carefully position the end of the plastic drain tube in
the pan. Make sure the tubing is not kinked and the end is located securely in the pan, so it does not touch the heating element.
Plug the power cord from the heater 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.

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.
6.
7.
8.
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.
24
OPERATIONS MANUAL
All refrigerant lines and components must be clean, free of
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
the atmosphere for more than five (5) minutes.
No refrigeration component, tubing or fitting shall be left
open to the atmosphere for more than ½ hour without
being soldered, capped or plugged.
Each completed refrigeration system shall be purged with
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 NONCFC 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
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 suction valve should be 30° +/- 5°. Expansion valve adjustment may be necessary to achieve this superheat.
Installation of the electric condensate heater is also the
responsibility of the installer (see “Installing Electric
Condensate Heater” under “Optional Accessories”).
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
REFRIGERATOR.
