RECEIVING YOUR NEW MODEL
Congratulations on your purchase of Continental Refrigerator
superior foodservice equipment! When your shipment arrives,
thoroughly examine the packaging for any punctures, dents, or
signs of rough handling. It is in your best interest to partially
remove or open the shipping container in order to examine the
contents for any missing accessories, or concealed damage
which may have occurred during shipment. If the cabinet is
damaged, it must be noted on the carrier’s delivery slip or bill
of lading (see “Filing a Damage Claim” under “Warranty”
section).
GENERAL INFORMATION AND
IMPORTANT OPERATING FACTS
This manual has been compiled to aid in the installation, operation and maintenance of your new equipment. Please take the
time to read it and familiarize yourself with your equipment and
its operation, to enjoy optimum performance.
Continental Refrigerator offers a variety of accessories for your
model (see “Optional Accessories” section towards the back
of this manual or contact your dealer for more information).
SERIAL DATA TAG
A serialized data tag is permanently attached to the inside righthand wall of your unit. (see Figure 1). In addition to identifying
the specific product, this label provides important information
regarding electrical requirements and refrigeration charge, as
well as agency listings and factory contacts.
FIGURE 1: Data Tag
IMPORTANT NOTE: The model and serial number should
be noted on the front cover of this manual, in the spaces
provided. If parts or service are ever needed for your unit,
this information will be required to verify warranty status
and to properly identify any parts that may be needed.
All cabinets must be given sufficient time to reach normal
operating temperature before placing any food inside cabinet
or pans (if equipped). For refrigerators, approximately 1 hour
of operation is required to lower the cabinet and pan temperature to 40°F (4°C). During pull-down of open top models, pans
should be in place and top lid should be kept closed. Freezers
require approximately 2 hours of operation to lower the cabinet
temperature to 0°F (-18°C) (see “Operation” section for further
information).
Prior to factory shipping, all products are performance-run
tested for a minimum of 12 hours providing a highly sophisticated temperature recording exclusive to each individual
cabinet. This recording is supplied within this manual packet. A
final evaluation, including analysis of cabinet performance, leak
check, vibration, noise level and visual examination is made by a
qualified quality control team to assure a superior product. The
carrier signs to this effect when they accept the product for shipping. To insure the maximum in safety and sanitation, all models
are listed under the applicable of Underwriters Laboratories and
National Sanitation Foundation standards.
UNCRATING YOUR NEW MODEL
The shipping container should remain on your cabinet to protect against dents or scratches while transporting to the actual
set-up location. Remove the shipping container only at the last
possible moment by using a pry bar to take out all the staples
from around the bottom of the crate. Slide the cardboard carton
up and off the unit, being careful not to rub against the cabinet.
Remove any accessories or boxes on the skid or in the cabinet.
Four (4) bolts secure the cabinet to the wooden skid. The bolts
are located at each end on the underside of the skid. In order to
remove these bolts, tilt the cabinet backwards and place wooden
blocks at each end in order to hold it in its tilted position. Using
a ¾” socket or open end wrench, remove the bolts and carefully
slide the model off of the skid. After skid removal, the cabinet
should never be moved without dollies or rollers to avoid damage to the cabinet bottom or floor.

WORKTOP/UNDERCOUNTERS & SANDWICH UNITS
IMPORTANT NOTE: Do not under any circumstances, lay
your new model on its front or sides. For a brief period
of time, you may lay the cabinet on its back, but only
when its properly blocked so as not to crush the louvered
venting panel and also to allow provision for your hands,
in order to set it in its upright position without damaging
the cabinet. Do not plug in and operate model for at
least three (3) hours after cabinet is set upright from
being on its back as this can damage the compressor.
INSTALLATION AND LOCATION
For optimum performance, “SW” series models should be
installed on casters or legs (see “Installing Casters” or
Installing Legs”) and a mini mum 3” clearance should be
provided on each side and the rear of the cabinet (see Figure
2). Your model has been designed to also operate sufficiently
without legs or casters and directly on the floor as long as a
minimum clearance of 8” is provided from the rear venting
louvers and the rear wall (see Figure 2). Cabinet side clearance
is not required when mounting your model directly on the floor,
without legs or casters. If any of the above conditions can not be
achieved, the installer should provide special venting or air supply ducts, or a Front-Breather Kit (see “Optional Accessories”)
can be ordered by contacting the factory.
Before moving the cabinet to its final point of installation, measure all doorways or passages to assure clearance. If additional
clearance is needed, you can remove the cabinet doors (see
“Removal of Doors and Door Adjustment”) and lids (when
equipped) (see “Removing Lid and Hood”).
“UC” series models and units provided with the Front-Breather
Option do not require any clearance around the the sides or
back of the cabinet, since they take in and exhaust air under the
cabinet and through the front grill, under the door. The air flow
under the cabinet and through the front grill cannot be restricted.
(see “Front Breather Kit” under “Optional Accessories”).
VENTILATION
The final location site of your air cooled refrigerator or freezer
must provide a large quantity of cool, clean air. All refrigeration
systems operate most efficiently and trouble-free with cool,
dry air circulation. Avoid locations near heat and moisture
generating equipment including ovens, cooking ranges, fryers,
dishwashers, steam kettles, etc., or in direct sunlight (where
temperatures can exceed 100°F). Do not select a location in an
unheated room or area where temperatures may drop below
55°F. Air supply to the condensing unit is equally important.
Restricting the air places an excessive heat load on the condensing unit and adversely effect its operation.
FIGURE 2: Minimum Clearance Dimensions for Optimum Conditions
IMPORTANT NOTE: To assure maximum operating effi-
ciency, your new cabinet should be located where an
unrestricted air supply can circulate underneath and
behind the cabinet. Do not at any time obstruct the grill
area in the rear of the cabinet in any way, and never place
or store anything inside of the cabinet machine compartment. These rules are essential for maximum cooling
capacity and long life of refrigeration parts.

OPTIONAL CASTER SHIM
(Reference #CM1-2476)
CASTER
FLOOR LOADS
The floor at the final location site must be level, free of vibration
and strong enough to support the total combined weights of
your new model plus the maximum product load which might
be placed into it. Keep in mind that all the weight is concentrated
at the caster or leg locations. A fully loaded reach-in model may
reach 2,000-3,000 pounds. To estimate the possible product
weight, assume that each cubic foot of storage space weighs
approximately 35 pounds. Multiply 35 pounds by the amount of
cubic feet in the cabinet to obtain the product load weight.
For example, a 20 cubic foot refrigerator can hold approximately
700 pounds of product (35 x 20). Assuming the cabinet itself
weighs 300 pounds, the total combined weight of cabinet and
product is approximately 1000 pounds. Therefore, the floor in
this example must be able to support up to 1000 pounds.
INSTALLING CASTERS AND LEVELING
If your new unit is supplied with swivel casters, they will be
packed in the accessory box that came with your cabinet.
Casters should be installed only when the cabinet is close to
it’s final installation site. To install casters on your new model,
carefully tip the unit back and position (4) 2” thick wood blocks
underneath. Locate the large threaded holes on the bottom of
the cabinet and screw the threaded caster studs into the mounting holes, closest to the front of the unit. Repeat this procedure
by tilting the cabinet in the opposite direction and installing
the remaining casters. Make sure the casters are tightened
extremely well (see Figure 3b). If the casters are not installed
tightly, the cabinet will be unstable and may sway or rock, which
can damage the cabinet.
FIGURE 3a: Installing Casters
FIGURE 3b: Casters Must Be Tight to Cabinet Bottom
If the height of a caster needs to be raised, shims must be
installed under the casters which need leveling. Extra large
washers, available at most hardware or furniture stores, can be
used to shim casters, or contact the factory for caster shims.
Do not attempt to level casters by unscrewing them
from the cabinet and leaving them loose, as this will
cause damage to the cabinet and leg hole threads,
voiding all warranties.
IMPORTANT NOTE: It is extremely important that your
cabinet is perfectly level for proper operation. If it is not
level, the following adverse conditions may occur:
1. The door(s) will not be properly aligned and
consequently will not provide a good seal.
2. Your unit may run excessively.
3. An excessive amount of ice will accumulate inside
the cabinet, around the door opening(s) and on the
finned evaporator coil. If allowed to continue, ice will
eventually block the coil and the unit will fail. This
can result in the loss of all food stored in the cabinet.
4. Defrost water will fail to drain properly and will
overflow the evaporator coil drain pan and into the
cabinet of both refrigerator and freezer models.

INSTALLING LEGS AND LEVELING
Your new is supplied with adjustable legs for leveling purposes.
Each model has four leg mounting holes on the bottom of the
cabinet. Legs are packed in the accessory carton from which
they must be removed and installed on the cabinet bottom
(see Figure 3). In order to install the legs, carefully tip the
cabinet back, adding four (4) 2” wood blocks underneath, and
simply screw the threaded leg studs into the case bottom front
leg holes. Repeat this procedure by tilting the cabinet in the
opposite direction and install the remaining legs. Make sure the
legs are tightened extremely well or the entire model will sway
or rock with each opening or closing of the doors, possibly
causing damage to the case bottom. This procedure should be
performed close to the final installation site and allow access
to the rear of the cabinet for condensate evaporator installation
(see “Installing Condensate Evaporator” under “Installation
and Location” section).
To assure your cabinet is level, all legs are equipped with bullettype leveling bolts. These bolts can be turned by hand or by
wrench, clockwise or counterclockwise to level the cabinet.
FIGURE 4: Leg Installation
CONDENSATE REMOVAL
No floor drains or plumbing connections are required since all
models use an automatic condensate water evaporating system
(see Figure 5). All models utilize a unique hot air condensate
water evaporating system which is completely self-contained
and no further assembly or maintenance is required. In some
adverse conditions such as high ambient temperature, high
humidity, extremely heavy usage, frequent loading for prolonged
periods of time, or heavy pan loading, the amount of condensate water generated could overflow the pan. If this occurs,
the plastic drain tube from the cabinet can be diverted directly
to a floor drain, bypassing the condensate pan. Alternatively,
an optional electric condensate vaporizer may be purchased
as an accessory. An electric condensate vaporizer is also supplied with all remote models. To install the optional condensate
vaporizer, follow the steps for (“Installing Electric Condensate
Vaporizer” in the “Optional Accessories” section) towards the
back of this manual.

REMOVAL OF DOORS AND DOOR ADJUSTMENT
During installation, it may become necessary to remove the
cabinet doors to facilitate passage through narrow doorways
or hallways. Depending on the age of your cabinet, the springloaded hinge cartridge is located either on the top or the bottom of the door. To remove a door, verify the location of the
spring-loaded cartridge (see Figure 8). Swing the door to the
open position (90°) and remove the mounting screws securing
the the hinge cartridge bracket to the cabinet (either above or
below the door).
CAUTION: THE HINGE CARTRIDGE IS SPRING LOADED
AND MAY SNAP TOWARDS THE DOOR WHEN THE
MOUNTING SCREWS ARE REMOVED. BE SURE TO HOLD
DOOR FULLY OPEN BEFORE REMOVING MOUNTING
SCREWS.
For doors with the spring cartridge on the bottom: after removing the bracket mounting screws below the door, carefully
lower the door straight down, and free of the pivot pin bracket
above the door. (For doors with the spring cartridge on top:
after removing the bracket mounting screws above the door,
carefully lift the door straight up, and off the pivot pin bracket
below the door).
All doors are aligned at the factory, however vibration during
transit may cause them to shift and realignment may be necessary. If the door(s) require realignment, proceed as follows:
Open the door (90°) and loosen, but 1. do not remove the
mounting screws securing both the top and bottom hinge
brackets to the cabinet.

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

If the hinge does not work as described, follow these steps:
1. Using the hinge upside down as a wrench, turn the
mechanism in the door 180° in either direction. The
mechanism should snap to a null point.
2. Remount the hinge as shown in Figure 8.
3. Repeat the test procedure as described above until the
hinge snaps back when it is moved from the open-door
position towards the closed-door position.

MOUNTING SELF-CLOSING HINGE MECHANISM
(For doors with hinge cartridge on bottom)
For proper operation of the self-closing doors on all sandwich
unit models, the hinge mechanism must be mounted to apply
tension in the proper direction (see Figure 8). When the hinge
is moved to the open-door position, it should be tension-free.
However, when the hinge is moved back into the closed position, it should snap back.
CAUTION SHOULD BE TAKEN WHEN CHECKING THE
SPRING LOADING AS THE HINGE COULD SNAP BACK
ON FINGERS.

REMOVAL AND REPLACEMENT
OF HINGE MECHANISM
To remove the hinge mechanism from the door, remove the door
from the cabinet as explained previously. As shown in Figure 8,
remove the hinge plate from the hinge mechanism by removing
the hinge pin screw. Also remove the horseshoe spring. Reinstall
the hinge pin screw only partially leaving about 1/8” of exposed
screw threads. Now, the hinge mechanism mounting screws
can be removed thus allowing the mechanism to be removed by
pulling on the hinge pin screw. If the mechanism does not readily slide out of the door, slide a claw hammer or forked prybar
under the hinge pin screw head and using a block of wood for
leverage, lift the entire mechanism out of the door. To install the
new hinge mechanism, reverse the above procedure.

To remove the lid covering the food pan area (see Figure 10),
lift it 1/2 way up and carefully push in on the left 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 to the left, so the pivot pin on the
opposite end is free from the hood. If you have an insulated lid,
to take out the liner and insulation, remove 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 edge of the
lid. To remove the hood, take out the screws located inside each
end and along the back edge.
