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 and Freight Claim must be filed with the ship­ping company. FREIGHT DAMAGE IS NOT COVERED UNDER

WARRANTY.

UNCRATING YOUR NEW MODEL

The protective packaging should remain on your cabinet to
avoid dents or scratches while transporting it to the actual set­up location. All shelving, accessories and legs or casters are
carefully packaged and secured inside your cabinet to prevent
damage. All doors are locked and the keys are conveniently
attached to the door handle. After moving your unit to its final
location, split the outer plastic wrap vertically, along one of
the corners of the cabinet. Remove the plastic and the protec­tive corner guards and any accessories or boxes on the skid.
Dispose of all packaging materials properly.

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

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. If caster support plates
are to be installed, save the bolts and washers (see “Mounting
Caster Support Plates” under “Optional Accessories”). 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 it’s properly blocked so as not to crush the back
or end panels 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.

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). 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 standards of Underwriters
Laboratories and the National Sanitation Foundation.

MODEL COMPONENTS

FIGURE 2: Standard Reach-In Refrigerator or Freezer

Standard Reach-In refrigerators and freezers have an internal
evaporator coil located behind the fan panel on the inside ceil­ing of the refrigerated compartment (see Figure 2). Designer
Line Reach-In, as well as all Pass-Thru, Roll-In and Roll-Thru
refrigerators and freezers have an insulated housing located on
top of the cabinet, that contains the evaporator coil, out of the
refrigerated storage area (see Figure 2A & 2B).

All warmers have an insulated housing located on top of the
unit, that contains a blower fan to circulate warm air inside the
cabinet (see Figure 2C). On most models, the high-wattage,
finned electric heating elements are located inside the cabinet,
at the bottom of the interior side walls. On single-section Roll-In
and Roll-Thru models, the heating elements are located in the
housing on top of the unit, to optimize space for carts inside
the cabinet.

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 and grill
(see “Door Removal and Adjustment” and “Grill Removal”).

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 affects its operation.

INSTALLATION AND LOCATION

For optimum performance, all models should be installed on
casters or legs (see “Installing Casters” or Installing Legs”)
with a minimum 12” above the grill and 3” on each side and
back of cabinet (see Figure 3). 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 can not be met, the installer should provide special
venting or air ducts.

IMPORTANT NOTE: To assure maximum operating effi­ciency, your new cabinet should be located where an
unrestricted air supply can circulate above and behind the
cabinet. Do not at any time obstruct the grill area in the
front of the cabinet in any way, and never place or store
anything on top of the cabinet machine compartment.
These rules are essential for maximum cooling capacity
and long life of refrigeration parts.

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
its final installation site. To install casters on your new model,
place wooden blocks along the back, at each end. Tilt the cabi­net back, using the wood blocks to help hold the cabinet in its
tilted position. 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 4 & 4A). If the casters are
not installed tightly, the cabinet will be unstable and may sway
or rock, which can damage the cabinet.

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. For maximum stability under extreme conditions, caster
plate assemblies are available from the factory (see “Optional

Accessories” section of this manual).

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. 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.

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.

INSTALLING LEGS AND LEVELING

If your new unit is supplied with adjustable legs, they will be
packed in the accessory carton in the cabinet. Your cabinet will
have either four (4) or (6) threaded mounting holes on the bot­tom of the cabinet (see Figure 5). 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.

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 5: Leg Installation

MOUNTING AND LEVELING

Roll-In and Roll-Thru Models

Roll-In and Roll-Thru models are designed to be mounted
directly on the floor without legs or casters (see Figure 6).

IMPORTANT: The floor where any roll-in or roll-thru unit
is to be located must be level and flat. If it is not, it must
be made level prior to attempting to install the cabinet.
THIS IS CRITICAL FOR ROLL-THRU MODELS.

After removing your Roll-In or Roll-Thru from the skid, you may
carefully slide it into position. To avoid damaging or racking
your cabinet, carefully push on the lower half of the case end.
Once the cabinet is positioned in its final location, check that it
is level and plumb in all directions. Using a carpenter’s level, at
least 3’ long, check the floor of the cabinet horizontally in each
direction. Also use the level to check the exterior sides and back
of the cabinet vertically. Using a carpenters square, check each
corner of the door openings, to insure they are at 90° angles. If
necessary, insert shims under the cabinet to make adjustments.
Recheck with the level and square, and carefully push on the
sides of the cabinet to make sure it is stable. The base of the
cabinet should be sealed to the floor around its entire perimeter
with NSF approved sealant, to meet sanitation requirements.

Your Roll-In and Roll-Thru model comes with one cart ramp
per door opening (see Figure 6). To install the ramp(s), simply
open the cabinet door and position the ramp with the wide edge
towards the front of the cabinet floor. Set the ramp so the slots
along the wide edge sit over the screws along the front of the
cabinet floor and push down to engage. If the door wiper rubs
along the ramp, to the extreme where the door will not self­close, you will need to adjust the door (see “Door Removal
and Adjustment” section) and/or level the cabinet as explained
above.

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:

The door(s) will not be properly aligned and conse-1.

Your unit may run excessively.2.
An excessive amount of ice will accumulate inside 3.
the cabinet, around the door opening(s) and on the
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.
Defrost water will fail to drain properly and will 4.
overflow the evaporator coil drain pan and into the
cabinet of both refrigerator and freezer models.

CONDENSATE REMOVAL

Interior Coil Models

No floor drains or plumbing connections are required since all
models use an automatic condensate water evaporating sys­tem. Standard Reach-In models feature an evaporator housing,
located on the inside ceiling of the refrigerated storage area
(see Figure 2) and an electric condensate vaporizer pan with a
mounting bracket packed in the accessory carton.

To install the vaporizer, remove the pan, power cord, cord clamp
and screw from the carton (see Figure 7). Connect the cord
to the vaporizer as shown. Route the cord around the outside
of the pan and through the clamp as illustrated. Secure the
cord and clip to the pan by fastening the mounting screw into
the threaded hole on the side of the vaporizer. Remove the (2)
mounting screws from the back of the cabinet. Position the
bracket as shown and place the vaporizer in the bracket, making
sure the power cord is routed as illustrated. Attach the bracket
to the cabinet with the screws. Using a sharp knife or scissors,
cut the drain tube so the end is about 2” below the bottom of the
cabinet. Place the end of the drain tube in the pan, making sure
the tube is not blocked, kinked, or sitting on the bottom of the
vaporizer pan. Check that the water level switch is operating cor­rectly by lightly pressing down on the top of the vaporizer, at the
end where the cord is attached. You will hear a “click” as pres­sure is applied and another “click” when pressure is removed. If
you do not hear the switch “click”, ensure the vaporizer is seated
in the bracket correctly and the cord is routed correctly and
secured in the clamp. Plug the power cord into the receptacle
labeled “VAPORIZER” on top of the cabinet.

IMPORTANT: It is extremely important that the water
level switch operates correctly, that the vaporizer is
plugged into the correct receptacle labeled “VAPORIZER”
and the compressor is securely plugged into the recep­tacle labeled “CONDENSING UNIT”. Improper installation
may cause your cabinet and/or vaporizer to not operate
correctly. This can result in water overflowing the pan and
onto the floor.

CONDENSATE REMOVAL

Top Mount Coil Housing Models

Designer Line Reach-Ins, as well as all Pass-Thrus, Roll-Ins and
Roll-Thrus feature an insulated evaporator housing, located on
the top of the cabinet, out of the food zone (see Figure 2A &
2B). These models utilize a unique self-contained hot air evapo­rating system to automatically eliminate condensate water.
No floor drains or plumbing connections are required and the
system is completely self-contained, so 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 reach-in and
pass-thru models. To install the optional condensate vaporizer,
follow the steps for “Interior Coil Models” in the previous
section. Remote roll-in and roll-thru models are supplied with
an electric heater in the condensate pan on top of the cabinet,
which must be connected to a power supply by the installer.

DOOR REMOVAL AND ADJUSTMENT

During installation, it may become necessary to remove the
cabinet doors to facilitate passage through narrow doorways or
hallways. To remove a door, carefully pry off all hinge covers
using a sharp tool or knife (see Figure 8A). Swing the door to
the open-door position (90°) and carefully lift the door upward,
so the hinge pin (attached to the door) clears the hinge body
(mounted to the cabinet). If it is necessary to remove the hinge
bodies from the cabinet face, use caution when loosening the
top hinge bodies, as they cover the light switch plunger. To rein­stall the door, reverse the above procedure. (For glass doors,
see “Optional Accessories”).

All doors are aligned at the factory, however vibration during
transit may cause doors to shift and adjustment may be neces­sary. If the door(s) require realignment, carefully pry off all hinge
covers (see Figure 8A) using a sharp putty knife or flat-blade
screwdriver. Loosen the screws securing the hinge bodies to the
face of the cabinet and slide the door into alignment. Hold the
door firmly in place and tighten all screws securely.

If the door gasket(s) do not seal properly to the cabinet face
and there are gaps between the gasket and the face on the hinge
edge, adjust the door by removing the hinge covers (see Figure
8A) and loosening the adjustment screws securing the hinge pin
to the door. Push the face of the door towards the face of the
cabinet, so the gasket firmly contacts the cabinet. If the door is
pressed too tight against the cabinet, the gasket will pinch along
the hinge side and the door will not close and seal properly. Hold
the door firmly in place and tighten all screws securely. Open
and close the door several times to check that the gasket seals
properly all the way around the door. Re-adjust if necessary and
make sure all screws are tight. Replace all hinge covers.

REMOVAL AND REPLACEMENT
OF HINGE MECHANISM

Before attempting any work on your refrigerator or freezer, it is
strongly recommended that all contents be removed and stored
in a walk-in or other refrigerated space. Disconnect power by
unplugging the cabinet, or switching off circuit breaker. The
following tools are needed to remove the hinge: straight-blade
screwdriver and philips screwdriver with large (#3) tip.

To remove a hinge, open the door approximately 90° and lift
it off the hinge bodies. Remove the hinge pin and adjustment
plate from the door (see Figure 8A) by loosening the adjustment
screws. Remove the hinge body from the face of the cabinet by
loosening the (3) flat-head machine screws. To remove the lock
keeper from the cabinet, remove the 2 screws on the inside edge
of the keeper (see Figure 8A) and slide it off the base. If the
white, nylon cam needs to be removed from the hinge body, a
straight blade screwdriver may be used to carefully pry the cam
out of the body. Be careful not to damage the cam, as the nylon
material is soft. Reverse the cam by rotating it 180° and pressing
it firmly back in place.

RE-HINGING DOORS (Reach-Ins)

Single section, solid long door models are rehingeable in the
field, without the need to modify the cabinet. A scraper or
flat-blade screwdriver, a philips screwdriver and wire crimpers
will be needed. Before attempting to rehinge your unit, unload
all contents and store in walk-in or other refrigerated space.
Disconnect power to the cabinet.

OPERATIONS MANUAL

Open the door approximately 90° and lift it off the hinges.
Remove the hinge pin assemblies from the door (see Figure
8A). Reverse each pin by rotating it 180° and reattaching it to the
door. Remove the hinge bodies and lock keeper(s) from the front
of the cabinet. Remove the white, nylon cam from the hinge
body. (A straight blade screwdriver may be used to carefully
pry the cam out of the body, without damaging it.) Reverse the
cam by rotating it 180° and pressing it firmly back in. Remove
the light switch from the front of the cabinet and pull the switch
out of the hole.

Remove the screws and plug button from the face of the cabi­net, on the opposite side hinge locations. The wires for the light
switch will be coiled up in the insulation, behind the plug button.
Carefully pull the wires out and install female connectors for the
light switch. Remove the old light switch from behind the top
hinge and remove the wire connectors.

REACH-INS & ROLL-INS

Cap each lead on the brown lamp cord separately, push the
wires into the insulation and insert the plug button into the hole.
Remove the cover from the control box, on top of the cabinet.
There will be a black lamp cord, with a tag identifying it as the
light switch wire. Install (2) female wire connectors on the black
lamp cord. There will be (2) brown lamp cord leads on the ter­minal block. Disconnect them and replace with the wires from
the black lamp cord. Cut off the old leads on the brown ripcord
and secure them out of the way, so they will not contact any live
wiring. Check that all wires are properly connected and secured.
Replace the control box cover. Remount the hinges and actuator
button for the switch to the face of the cabinet. Remount lock
keeper and door. Reconnect power to the cabinet.

NOTE: All wiring and connections should only be made by
a qualified electrician.

REMOVING GRILL

To remove the grill, loosen, but do not remove, the (4) mounting
screws located on the back side of the grill at the ends. Simply
lift grill up off of its mounting screws and out. To replace the
grill, line up the grill mounting screws with the keyhole slots
located on the cabinet body, push in and down on the grill.

IMPORTANT NOTE: The wiring to the anti-condensate
switch and the thin copper tubing or cable for the ther­mometer are provided with leads long enough to allow
the grill to be laid across the top of the cabinet after it
has been removed. Take care not to damage the wires or
copper tubing when handling the grill.

If you need to completely remove the grill from the cabinet,
disconnect the power supply to the cabinet. Remove the wires
on the back of the anti-condensate switch on the grill. Locate the
thermometer sensing bulb and cover, located inside the cabinet.
On Standard Reach-In models, the thermometer bulb cover
is under a small cover channel on the interior top left corner
towards the front of the cabinet. On Designer Line, Pass-Thru,
Roll-In and Roll-Thru models, the thermometer bulb is located
on the interior top, under the air duct. Remove the cover, care­fully grasp the bulb and push it back through the cabinet hole.
The thermometer bulb and grill can now be removed from the
cabinet. When reinstalling the thermometer bulb, be sure to
replace the sealant putty around the hole into the insulation.
Reattach the leads for the anti-condensate heater switch and
reconnect the cabinet’s power supply.

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 “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).

Refrigeration compressors are designed to operate within
+/-10% of the rated voltage indicated on the cabinet serial
plate. Excessively high or low supply power can burnout the
compressor. This can be easily detected and will void the fac­tory warranty. Full voltage at the correct rating, on a separate,
designated circuit, not affected by the operation of other electri­cal appliances, must be available to the refrigeration unit at all
times. Extension cords should never be used on commercial
equipment, as they can overheat and/or result in low voltage.

GFI/GFCI RECEPTACLES

Building codes in some areas may require certain 115 volt
receptacles to be protected by a Ground-Fault Circuit Interrupter
(GFCI or GFI). These devices are not recommended for most
commercial refrigerators and freezers, since nuisance trips can
occur (typically due to moisture) causing temporary loss of
power. This may result in intermittently high storage tempera­tures and potentially unsafe food product. If you decide to con­nect your equipment to a GFCI protected receptacle, a properly
sized, commercial grade circuit breaker should be used on a
separate, designated power supply. Alternatively, a qualified
electrician may be able to hard wire your equipment, eliminat­ing the need for a GFCI device. Contact Continental’s Service
Department before making any modifications to your cabinet, to
avoid loss of warranty coverage.

NOTE: GFCI DEVICES ARE NOT RECOMMENDED.
PRODUCT LOSS AND/OR PROBLEMS RESULTING FROM
NUISANCE TRIPS OR CONNECTION TO A DEFECTIVE
OR IMPROPER POWER SUPPLY, ARE NOT COVERED
UNDER WARRANTY. UNAUTHORIZED MODIFICATIONS

TO YOUR EQUIPMENT OR THE POWER CORD CAN
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:

115 VOLT, 60 HZ, 1 PHASE CONNECTION

All 115 volt models are provided with a factory
installed, UL approved 15-amp power cord and
NEMA 5-15P plug, or a 20-amp cord with a
NEMA 5-20P plug. To insure proper operation,
this equipment must be plugged into a NEMA
compatible, grounded receptacle that can sup­ply the full voltage and amperage stated on the
serial plate (see Figure 1).

IMPORTANT NOTE: A SEPARATE, ISOLATED, PROPERLY
SIZED POWER SUPPLY MUST BE PROVIDED. GFCI
DEVICES AND/OR EXTENSION CORDS SHOULD NOT
BE USED. PRODUCT LOSS, AS WELL AS PROBLEMS
RESULTING FROM NUISANCE TRIPS OR HIGH/LOW
VOLTAGE, ARE NOT COVERED UNDER WARRANTY.

1. Check that all exposed refrigeration lines are free of kinks.

2. Check that the condenser fan and evaporator fans are free
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 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 products are available for purchase as remote models, in
which case the condensing unit is not supplied with the cabinet.
All remote models come standard on 6” legs, with an expansion
valve in the evaporator housing, as well as stubs for the liquid
and suction refrigeration line connections. 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”).

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. 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.

DIAL THERMOMETER AND CALIBRATION

Your NSF-approved dial thermometer has a remote sensing
bulb, located in the refrigerated compartment. The display fea­tures a large 2” diameter face, with any easy to read scale that
shows the internal cabinet temperature in Fahrenheit (°F) and
Celsius (°C). Blue (safe) and red (caution) color bands provide a
quick, visual indication of the temperature inside your refrigera­tor or freezer. The thermometer is pre-calibrated at the factory,
to accurately show the cabinet temperature.

To check the accuracy of your ther­mometer, place a pre-calibrated
temperature sensing device in the
center of the refrigerated compart­ment and keep the door closed for at
least 10 minutes. The thermometer
should read the same temperature
as the sensing device, within +/-2°F
(+/- 1°C). If it does not, use a small
straight-blade screwdriver to care­fully pry the clear lens cover from the
thermometer body as shown (see
Photo A).

Use a small straight-blade screwdriver to hold the center hub
stationary and use your finger to carefully turn the needle to the
desired temperature, as shown (see Photo B). Replace the lens
cover and recheck the calibration.

DIGITAL THERMOMETER AND CALIBRATION

Your NSF-approved thermometer has a remote sensing bulb,
located inside the cabinet on left-hand wall. The easy to read
24-Volt LED display is calibrated at the factory to accurately
show temperature at the center of the refrigerated compartment.
While in transit, your cabinet will be subjected to more jarring
and vibration than at any other time, and the thermometer may
require adjustment at start-up.

Refrigerators are designed to maintain 38° to 40°F (3.3° to

4.4°C); Freezers -2° to 0°F (-19° to -18°C). During periods of
heavy use, when doors are opened repeatedly or remain open for
an extended period, or if warm product is loaded into the cabinet,
the temperature displayed may temporarily exceed the “normal”
range. This is common, as warm air outside the cabinet mixes
with cold air inside. If your thermometer continues to display
temperature above “normal” range, close the doors, make sure
they seal tight and keep them closed for at least 30 minutes. If
a high temperature is still displayed, check the thermometer by
placing a pre-calibrated temperature sensing device in the center
of the refrigerated compartment and keep the doors closed for
at least 15 minutes. The thermometer display should read the
same temperature as the sensing device, within +/-2°F (+/-1°C).
If it does not, follow the instructions below to calibrate the ther­mometer display, by adjusting the offset value as required.

To calibrate, press on the right center of the front display twice
(see photo). After the first press, “CAL” will appear (unit is in
Calibration mode). After the second press, the temperature off­set value (-30 to 30) will appear.

Press here for

calibration modePress here to decrease temp.

Press here to decrease temp.

OPERATIONS MANUAL

13

REACH-INS & ROLL-INS

Once you see this, press on the front lower left to decrease
temperature displayed, or on the upper left section to increase
temperature displayed. After adjusting the offset, press the right
center of the front display again to exit calibration mode. Wait 10
to 15 seconds for the cabinet temperature to appear and recheck
the display calibration.

For example, if sensing device in the cabinet reads 38° and
thermometer displays 41°, press on the front right of the display
twice to show the current offset value. Then press the lower left
of the display three times to decrease offset by 3°. (If the original
offset value displayed was “0”, then “-3” will appear.)

NOTE: The buttons need to be pressed without delay
between actions. Contact the factory with any questions.

ANTI-CONDENSATE CONTROL

All Continental upright models feature an anti-condensate door
heater switch, located on the front grill (see Figure 2, 2A &
2B). To save energy, move the switch to the OFF position to
deenergize the heaters around the perimeter of the cabinet door
openings. If you ever notice moisture accumulating on the face
of your cabinet, move the switch to the ON position to energize
the heaters. This will warm the face of the cabinet, eliminating
any condensation that may accumulate.

Refrigerators and freezers built after January, 2010 have an
energy saving thermal limit switch, mounted in the control box
(see Figure 9, 9A & 9B). This device automatically monitors
ambient conditions and turns the anti-condensate heaters off
whenever they are typically not required. The switch automati­cally turns the heaters back on when the temperature rises to a
level when the additional heat is normally needed to eliminate
condensation.

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 from the top of the
electrical console box located on the cabinet top behind the front
grill (see Figure 9, 9A & 9B). 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.

FREEZER SYSTEM AND ADJUSTMENT

All self-contained freezers are factory set to maintain an average
cabinet temperature of -4° to 0°F (-20° to -18°C). These prod­ucts are designed to hold 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 from the top of the elec­trical console box located on the cabinet top behind the front
grill (see Figure 5). If an adjustment is necessary to maintain
the above temperature range only on standard freezers, place
a screwdriver into the thermostat slot and turn clockwise for a
colder cabinet temperature or counterclockwise for a warmer
cabinet temperature. On low-temperature freezers, place a
screwdriver into the right thermostat adjustment screw (do not
turn the left differential adjustment screw) 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 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 (3) defrost periods per day at 8-hour intervals
with fail safe cut-off time of 20 minutes. Any modifications to
these settings will cause problems with your unit, including
evaporator freeze ups, which will not be covered under warranty.
The clock is pre-set to initiate defrost at 6am, 2pm and 10pm.
These times are adjustable, but all 3 must be changed simultane­ously, to maintain 8-hour interval between defrost periods.

face counterclockwise
as the arrows indicate until the correct time of day is lined up
with the “time” arrow on the upper left corner of the clock. It will
be necessary to reset the time of day on the timer if the freezer is
turned off or has loss of power. To relocate and/or add a defrost
period, simply unscrew the defrost pins located around the outer
dial and screw them into the desired time slots (an additional pin
is located in a storage slot on the right side of the dial).

IMPORTANT NOTE: All freezers have a unique, energy­saving defrost cycle. It is time initiated, temperature
terminated, with an automatic, auxiliary time cut-off
safety to minimize electrical consumption and provide
for the shortest possible heating cycle. This safety time
cut-off is factory set at 32 minutes and should not require
any further adjustment. After defrost, the fan delay con­trol prevents the evaporator fans from operating until
the evaporator coil has reached a temperature of 32°F
(approximately 20 minutes) thus, minimizing warm air
circulation inside the cabinet. Therefore, during initial
start-up, and after each defrost cycle, the fans will not
turn on immediately.

Warming cabinets are not designed to cook food. All foods
placed in the warming cabinet should be precooked and at, or
above the desired holding temperature. Never place cold or
uncooked foods in the cabinet. It is recommended that hot
foods be kept above 140°F to retard bacterial growth. Foods that
are steaming should always be covered.

IMPORTANT NOTE: The operating range of the warmer
temperature control is is 60°F to 180°F. Never allow
the cabinet temperature to exceed 200°F since serious
damage could result to your warming cabinet and the
warranty will become null and void.

STANDARD REACH-IN REFRIGERATION SYSTEM

Ceiling-Mount Evaporator

The low-profile evaporator system is comprised of a gener­ous sized, evenly matched evaporator and air circulating fans
contained within an easily accessible, low silhouette, interior
ceiling mounted housing (see Figure 9). A control box, located
on top of the cabinet, contains the temperature control, thermal
limit switch, defrost time clock (for freezers) and other electrical
components.

All standard reach-in refrigerators and freezers built after June,
2009 have a unique, modular refrigeration system. The com­plete, fully charged refrigeration unit can be easily removed from
the cabinet for locations with restricted access for installation,
servicing, conversion from a refrigerator to freezer (or vice
versa) or other needs. Contact the service department for more
information.

preheat your new warming cabinet to the desired temperature
before placing any food into it. To operate, turn the thermostat
knob located on the upper grill panel, from the “off” position to
the desired cabinet temperature. When the desired temperature
is reached and displayed on the exterior thermometer, preheat­ing is complete and the cabinet is ready to be loaded. Please
note that setting the thermostat higher than the desired tempera­ture will not provide quicker preheat warm-ups.

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, remove all
product from inside and temporarily move it to a walk-in or
other refrigerated storage.

2. Open all doors and allow the cabinet to reach room temp-
erature. Remove all accessories (shelves, racks, pilasters,
clips, etc.) from inside and wash them with a baking soda
and warm water solution, rinse thoroughly with clean water.
Dry all accessories completely with a soft clean cloth.

3. Once the cabinet has reached room temperature, wash all
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. Rinse thoroughly with clear water
and dry with a soft clean cloth. Carefully wash all of the
vinyl door gaskets with clean water, dry them and check for
any damage, which may affect the seal. 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 original locations, reconnect
the power. Wait at least 1 hour before reloading product
into your unit.

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

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 on top of
the cabinet, 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 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 front grill, to
check for debris or blockage (see Figure 11, 11A & 11B).

If the condenser coil is dirty or blocked, disconnect the cabinet
power supply and using a stiff brush, wipe away any 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.

CAUTION: CONDENSER FIN PLATES ARE MADE FROM
THIN METAL AND HAVE SHARP EDGES. ALWAYS
WEAR GLOVES. USE CAUTION WHEN WORKING ON
OR AROUND THE CONDENSING UNIT TO PREVENT
CUTS AND AVOID DAMAGING FINS, TUBING AND
OTHER COMPONENTS. FAILURE TO PROPERLY CLEAN
THE CONDENSER REGULARLY WILL CAUSE EXESSIVE
COMPRESSOR LOAD, REDUCING THE PERFORMANCE
AND EFFICIENCY OF YOUR UNIT. THIS CAN RESULT IN
PREMATURE FAILURE AND VOID YOUR WARRANTY.

CARE AND CLEANING OF STAINLESS STEEL*

*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.

There are 3 basic things that can break down the protective
layer on your stainless steel, which must be avoided:

DO NOT USE: abrasive

cleaners, chemicals with
chlorides or muriatic
acid to clean your
equipment.

HARD WATER3. 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.

MECHANICAL ABRASION1. 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: steel pads, wire brushes, scrapers or
knives to clean your equipment.

CHLORIDES2. are found in water, salt, food and worst

of all, many cleaners. Only use chloride-free, alkaline­based, non-abrasive cleaners. Always rinse 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.

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 rinse, rinse, rinse
thoroughly with cool, clean, clear water.

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.

compressor, an “over-the-counter” exchange must be made
at an authorized Copeland, Danfoss, Embraco, or Tecumseh
wholesaler.

After the first year, the compressor motor is covered under an
extended “parts only” warranty. The customer is responsible for
any labor charges and any additional parts that may be required.

Continental offers a variety of accessories for your unit.

PAN SLIDE ASSEMBLIES

Pan slide assemblies are available in a variety of configurations
(see Figure 11). The unique design of the vertical supports
allow the pan slides to be mounted on 1” centers and be read­ily removed for cleaning, without the use of tools or additional
hardware. If your new unit was ordered from the factory with
pan slides, the vertical supports will be pre-installed directly on
the outer walls of the cabinet. On 2- and 3-section cabinets, the
vertical pan supports in the middle of the cabinet are mounted to
center supports as shown (see Figure 11A). The pan slides are
wrapped up in the accessory package, inside the cabinet.

FIGURE 11: Pan Slide Assembly Configurations

PAN SLIDE INSTALLATION

Pan slides should be installed in pairs, to ensure each set is
level at the same height. Before installing the slides, determine
the spacing desired between each pan that will be placed in the
cabinet. Align one of the pan slides against the vertical support
(see Figure 11A). Simultaneously insert the (2) studs on the
slide into the upper end of the slot on the vertical supports at the
desired height and the pan slide will simply drop down and lock
into place. Install another slide into opposite vertical supports,
using the same method. Check that the pair of slides are level
and at the proper height. Repeat this procedure for the remain­ing sets of pan slides.

HINGED GLASS DOOR REMOVAL
AND ADJUSTMENT

Removal and adjustment of hinged glass doors are similar to
solid doors except that heated glass doors have an electrical
cord attached to the cabinet. Before attempting to remove a
glass door, disconnect the cabinet from the power supply. Using
a phillips screwdriver, loosen the retaining screw from the mold­ed plug and gently pull the plug out of the molded receptacle.
Carefully pry off all hinge covers using a sharp tool or knife (see
Figure 12). Swing the door to the open position (90°) and care­fully lift the door upward, so the hinge pin (attached to the door)
clears the hinge body (mounted to the cabinet). If it is necessary
to remove the hinge bodies from the cabinet, use caution when
loosening the top hinge body, as they contain the light switch
actuator (see Figure 8A).

SLIDING GLASS DOOR REMOVAL
AND ADJUSTMENT

All sliding glass doors are easily removable for thorough clean­ing. To remove the doors, slide the outer door (see Figure

13) open about half way, grasp the door on both sides and lift
straight up, off roller track, which will remain in the mounting
frame. Tilt the bottom of the door out, so it clears the locating
studs on the roller track and the bottom of the mounting frame.
Gently set the door down, being careful not to over-stretch the
self-closing spring and power cord that are attached to the top of
the door. Move the door towards its closed position, to release
any tension on the spring and power cord. The roller track will
simply lift out of the channel in the bottom of the mounting
frame. Repeat this procedure for the inner door.

To replace the doors, reverse the steps above, making sure the
door seats properly over the locating studs on the roller track.

If your sliding door does not close firmly, remove the doors,
starting with the outer door, as described above. Check the bot­tom of the door, mounting frame channel, and rollers to make
sure they are clean and free of debris. If the rollers are damaged
or do not turn freely, contact the factory to order replacement
parts. The tension on the self-closing spring is adjustable, to
provide quicker and firmer closing, or to provide slower and
more gentle movement. Remove the screw attaching the end
of the self-closing spring to the top of the door. Note that there
are (3) threaded holes provided in the top of the door. To adjust
the door so it closes slower, reattach the spring at a position
closer to the handle side of the door. For a faster, firmer closing,
relocate the spring at a position further away from the handle
side of the door.

If the door does not seal evenly along the handle side when
in the closed position, the tilt of the door is adjustable. A flat
washer can be placed over the locating stud on the top of the
roller track, between the track and the underside of the door, to
level the door. For example: if the door contacts the mounting
frame at the top when it is closed, but there is a gap at the lower
half of the side edge, remove the door as described above. After
lifting the door off the roller track, place a flat washer over the
stud located closest to the handle side of the door. Replace the
door, recheck the seal, and readjust if needed. (To close a gap at
the upper half of the door, place a washer over the locating stud
farthest from the handle side of the door.)

IMPORTANT NOTE: The glass used in sliding or hinged
glass doors is of special, sealed pane design and can­not be replaced with ordinary window or plate glass.
If it becomes necessary to replace the glass, it can be
obtained directly from the factory.

While in transit, your cabinet is subjected to more jarring and
vibration than at any other time, and the display may require
some adjustment at start-up. Refrigerators are designed to
maintain 38° to 40°F (3.3° to 4.4°C) and Freezers -2° to 0°F
(-19° to -18°C). During periods of heavy use, when doors are
opened repeatedly or remain open for extended period, or if
warm product is loaded in the cabinet, the temperature displayed
may temporarily exceed the “normal” range. This is common, as
warm air outside the cabinet mixes with cold air inside. If your
thermometer continues to display temperature above “normal”
range, close the doors, make sure they seal tight and keep them
closed for at least 30 minutes. If a high temperature is still
displayed, check the thermometer by placing a pre-calibrated
temperature sensing device in the center of the refrigerated
compartment and keep the doors closed for at least 15 minutes.
The thermometer should display the same temperature as the
sensing device, within +/-2°F (+/-1°C). If it does not, follow
instructions below for calibration mode to adjust the offset.

CASTER SUPPORT PLATES

MOUNTING CASTER SUPPORT PLATES

If 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.

IMPORTANT NOTE: Always wear proper work gloves and
use appropriate safety equipment. You may CAREFULLY
lay the cabinet on its back, but only FOR A BRIEF PERIOD

OF TIME. Caution must be taken to ensure you DO NOT
DAMAGE the back or side panels, as well as the copper

tubing and refrigeration components located on top of
your cabinet. The cabinet must be properly blocked, to
allow room to get your hands in to lift without damaging
the cabinet or crushing the end panels. DO NOT PLUG-IN

OR OPERATE THE REFRIGERATION SYSTEM FOR AT
LEAST THREE (3) HOURS AFTER THE UNIT HAS BEEN
RETURNED TO AN UPRIGHT POSITION, AS THIS CAN
DAMAGE THE COMPRESSOR.

FIGURE 14: Caster Support Plates

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.

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 14). 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.

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
system back on, and at least another 30 minutes for the cabinet
to come down to temperature and stabilize, before reloading
with product.

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.

The CFC-Free refrigerant used in standard remote and self­contained models is R-134a for refrigerators and R-404a for
freezers. All compressors and systems designed for these
refrigerants 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.

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”).

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.

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
