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 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). 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.
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 protective packaging 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.
All doors are locked and the keys are conveniently attached to
the door handle. After moving unit to its final location, remove
plastic and protective corner guards and any accessories or
boxes on the skid. Dispose of all packaging materials properly.
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”).
OPERATIONS MANUAL

REACH-INS & ROLL-INS
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.
MODEL COMPONENTS
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.

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 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 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 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
cannot be met, the installer should provide special venting or air
ducts, as required.
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 on the condenser or on
top of the cabinet machine compartment. These rules are
essential for long life. FAILURE TO FOLLOW THESE
GUIDELINES MAY VOID YOUR WARRANTY.

INSTALLING CASTERS AND LEVELING
FIGURE 3: Minimum Clearance
(Typical Reach-In Model Shown)
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).
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 4: Installing Casters
CASTER INSTALLATION
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
A
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 ROLL-IN AND ROLL-THRU MODELS
Roll-In and Roll-Thru models are designed to be mounted
directly (without legs or casters) on a flat floor surface in your
building (see Figure 6). The bottom off the cabinet is only about
½” thick, to make it easy to roll carts up and into the storage
area. Roll-Ins and Roll-Thrus must be installed plumb (vertically straight), level (horizontally even) and square for proper
operation of doors and refrigeration system. Proper installation
is similar to Walk-Ins and should only be done by a qualified
technician.

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.

ters or less, for adequate support along the entire length. After
the walls are level and plumb, place additional shims under the
length and width of the floor, to provide enough support for the
cabinet and its contents.
NOTE: Shims and sealant are provided with all new rollthru models, to aide proper installation. Any shim material used must be high density plastic, metal, or other solid
that will not deteriorate due to moisture. Wedge shaped
or flat shims 1/16”, 1/8” and 1/4” thick, and at least 3”
inches wide to match thickness of the cabinet walls, may
be used. Failure to properly shim under the entire floor of
the cabinet will cause it to bend.
The best way to ensure a trouble-free installation is to have a
flat, level surface where the unit will be located, prior to setting
the cabinet in place. If the building floor is sloped or uneven,
due to floor drains or other conditions, a leveling bed should
be constructed. Otherwise it will be necessary to shim and
anchor the cabinet thoroughly, to ensure it remains stable and
the doors operate correctly. Make sure flooring is fully cured
before moving the cabinet into position. Grout and concrete can
release chemicals while curing, which may corrode stainless
steel.
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:
CABINET INSTALLATION
Your cabinet should remain on the skid, with the protective
packaging in place, until transported to the final location. After
the cabinet is in the proper area, remove the door(s) by lifting
them off the hinges and setting them in a safe location. Remove
cart ramp(s) at each opening by lifting off the fasteners attached
to the bottom face of the cabinet. The cabinet can be moved a
short distance, into its final position, by carefully pushing on the
lower half of the sides.
NOTE: Use care when handling the doors, as they are
large and heavy. Do not to damage the flexible wipers at
bottom of the doors. To avoid damaging or racking your
cabinet, only push on the sides at a height between 24”
and 48” from the floor.
CABINET LEVELLING AND SHIMMING
After the cabinet is in its final, proper location, remove the grills
and upper end panels. Place a 2 foot (or longer) carpenter’s
along the top edges and floor of the cabinet to check level. Use
the level to check if the sides of the cabinet are plumb (vertically). Use a framing square to check the corners of the cabinet.
If the cabinet is not level, plumb and square, us a level to check
the cabinet floor in all directions and determine the highest area.
The cabinet must be shimmed to level the unit up to this point.

After the unit is completely level, caulk around the perimeter
with an NSF approved sealant, to secure the cabinet in place and
comply with sanitation requirements. Reinstall all grills, upper
end panels, and cart ramps. Check alignment and adjust as
required. Reinstall all doors and verify they seal properly. Make
sure the bottom of each wiper gently touches the ramp when
each door are closed. Adjust hinges and trim wipers if needed.
Determine the starting point for leveling, by identifying where
the cabinet is most plumb, straight and square. Insert a tapered
wedge under the adjacent walls, as needed, to raise them up to
a level position. Place shims under the side walls, on 12” cen-

The door(s) will not be properly aligned and consequently will not provide a good seal.
Your unit may run excessively.
An excessive amount of ice will accumulate inside
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
overflow the evaporator coil drain pan and into the
cabinet of both refrigerator and freezer models.
OPERATIONS MANUAL
NOTE: If your cabinet is located adjacent to another Roll-In
or Roll-Thru, Tie-In Strips (see “Optional Accessories”
section) may be installed for additional stability. Contact
the factory for more information and to order part kits.
REACH-INS & ROLL-INS
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.
ELECTRIC VAPORIZER WITH WATER LEVEL SWITCH
REACH-IN CABINET
FIGURE 7: Electric Condensate Vaporizer
IMPORTANT: It is extremely important that the water
level switch operates correctly, that the vaporizer is
plugged into the receptacle labeled “VAPORIZER” and
the compressor is securely plugged into the receptacle
labeled “CONDENSING UNIT”. Improper installation may
cause your cabinet or vaporizer to operate “erratically.”
This can result in water overflowing the pan and onto
the floor.
CONDENSATE REMOVAL(Top Mount Coil 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

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 plastic putty knife (see Figure 8). Swing
the door open 90° and carefully lift the door up, so the hinge
pins attached to the door clear the hinge bases mounted to
the cabinet. If it is necessary to remove the hinges, follow the
instructions below. 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 tool or plastic putty knife.
Loosen the screws securing the hinge bases 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
or there are gaps between the gasket and the face on the hinge
side, adjust the door seal by removing the hinge covers 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. Do not press the door
too tight against the cabinet, or 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.
FIGURE 8A: Reach-In/Roll-In Hinge Adjustment
HINGE REMOVAL AND REPLACEMENT
Before attempting any work on your refrigerator or freezer,
always disconnect power by unplugging the cabinet, or switching off the circuit breaker. It is strongly recommended that you
also remove all contents and store them in a walk-in or other
refrigerated space. The following tools are needed to remove
the hinge: plastic putty knife and philips screwdriver with large
(#3) tip.
To remove the hinge pin from the door (see Figure 8A) loosen
the adjustment screws and remove the adjustment plate and pin.
To remove the hinge base from the face of the cabinet loosen
the (3) flat-head machine screws. Use caution when removing
the top hinge base, as it contains the light switch. To remove the
lock keeper from the cabinet, remove the 2 screws on the inside
edge of the keeper (see Figure 8) and slide it off the base. If the
white, nylon cam needs to be removed from the hinge base, a
plastic putty knife 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.
RE-HINGING DOORS (Reach-Ins)
Single section, solid long door models are rehingeable in the
field, without the need to modify the cabinet. A plastic putty
knife, 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. Open the door 90° and lift it off the hinge bases.
Remove the hinge pins from the door (see instructions above).
Reverse each pin by rotating it 180° and reattaching to the door.
Remove the hinge bases and lock keeper(s) from the front of the
cabinet (see above). Use caution when removing the top hinge
base, as it contains the light switch. Remove the white, nylon
cam from each hinge base and reverse it by rotating 180° and
pressing firmly back in place. (A plastic putty knife may be used
to carefully pry the cam out of the base without damaging it).
Remove the filler screws and plug button from the face of the
cabinet, on the opposite side (new hinge locations). Wires for
connecting the light switch will be coiled up in the insulation,
behind the plug button. Carefully pull the wires out and install
female push-on connectors. Remove the old light switch from
the original top hinge location by disconnecting the push-on wire
terminals. Cap each lead wire separately, push the wires into the
insulation and insert the plug button into the hole. Connect the
light switch to the wire terminals at the new top hinge location.

To finish the cabinet wiring modifications, 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 hinge bases to the face of the cabinet. Install the
light switch into the top hinge base by sliding the flanged edge
into the slot on the back side of the base. Remount the lock
keeper and door. Adjust the doors as needed and 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
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.
NOTE: GFI RECEPTACLES ARE NOT RECOMMENDED,
PRODUCT LOSS OR SERVICE PROBLEMS RESULTING
FROM NUISANCE TRIPS, CONNECTION TO A DEFECTIVE
OR IMPROPER POWER SUPPLY, AND UNAUTHORIZED

115 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115 volt models are provided with a factory
installed, UL 15-amp power cord and NEMA
5-15P plug, or a 20-amp cord with NEMA 5-20P
plug. Your unit must be plugged into a compatible, grounded receptacle that can supply the full
voltage and amperage stated on the serial plate
(see Figure 1).
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

The system should run smooth 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.
OPERATION WITH MECHANICAL THERMOSTAT
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).
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, next page). 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.
NOTE: The buttons need to be pressed without delay
between actions. Contact the factory with any questions.
Use a small straight-blade screwdriver and place on center
slotted hub of thermometer. Carefully hold the needle and turn
the center screw clockwise to lower and counterclockwise to
increase the desired temperature, as shown (see Photo B).
Replace the lens cover and recheck the 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 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.
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.)
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.
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 left thermostat adjustment screw (do not
turn the right 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 evaporator coil defrost and drain
pan heater(s), a defrost time clock and temperature limit/fan
14
OPERATIONS MANUAL
REACH-INS & ROLL-INS
delay switch. The system is time initiated by the defrost clock
and temperature terminated by an automatic limit switch. During
each defrost period, the condensing unit and evaporator fans go
off, while the defrost heater(s) are energized. After termination
of a defrost cycle, the heaters go off and the condensing unit
turns on. The evaporator fans remain off (for about 20 minutes)
until the coil is cools down to a preset temperature (typically
32°F). This defrost drip time, which allows any remaining water
to clear off the evaporator coil, also ensures that only cold air is
circulated throughout the storage compartment.
After your freezer has been properly installed and electrically
connected, the defrost clock should be set for the correct time of
day and desired defrost start time. Set the timer for one defrost
period per day, with a fail-safe cut-off time of 20 minutes, as
shown.
The time clock is located in the electrical control box, which has
a window that provides access to the timer dial. The scale on
the inner “120 MINUTE DIAL” indicates the maximum time in
minutes for the duration of each defrost period. The scale on the
outer “24 HOUR DIAL” represents the actual time of day.
To set the clock for the correct time, turn the knob at the center
of the dial counterclockwise until the current time of day, as
indicated by the scale on the outer dial, aligns with the arrow on
the “CURRENT TIME INDICATOR” in the upper left corner.
NOTE: If there is ever a loss of power to your freezer,
the clock must be reset for the correct time after power
is restored, to maintain the same time of day for defrost.
IMPORTANT NOTE: All freezers have a unique, energy
saving defrost cycle, as described above. As explained,
after defrost the automatic fan delay prevents evaporator
fans from operating until the coil has reached a preset
temperature, minimizing warm air circulation in the cab
net. During start-up and after a defrost cycle, fans will not
turn on immediately.
Settings should only be adjusted as noted, to minimize
electrical consumption and provide the most efficient
heating cycle. Contact the factory before making modifications to any settings not described above. Improper
adjustments can cause problems with your unit, including loss of product and evaporator freeze ups, which are
not covered under warranty.
WARMER SYSTEM AND ADJUSTMENT
To set the start time for the daily defrost period, simply unscrew
the defrost pin located around the outer dial and screw it into the
threaded hole on the dial face at the desired time. Spare pins can
be placed in the storage slot located to the right side of the dial.
In some extreme applications, where there is very heavy usage,
excessively high humidity and/or constant door openings, additional defrost period(s) may be desired to ensure your evaporator remains free of any frost accumulation. To add a defrost
period, simply remove a spare pin from the storage slot and
screw it into the threaded hole at the desired time on the dial.
A maximum of 3 defrost periods a day, with 8-hour intervals
between defrost periods, is acceptable.
All Designer Line warming cabinets are designed with an operating range of 60°F to 180°F and factory performance run tested
to maintain an average cabinet temperature of 150°F. Always
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.
OPERATIONS MANUAL

REACH-INS & ROLL-INS
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.

RESULTING IN POOR PERFORMANCE AND SERVICE
ISSUES, SUCH AS COIL FREEZE-UP, WHICH WILL NOT
BE COVERED BY WARRANTY.
Your new cabinet comes with (3) shelves per section for standard solid door models, or (4) shelves per section for glass door
models, and (4) support clips per shelf.
SHELVING INSTALLATION
Pilaster strips for mounting the shelves are secured to the cabinet walls with special screws which allow the strips to be readily
removed for cleaning without the use of tools. To install the
shelving, determine the desired location for the shelves in each
section of your cabinet. For proper airflow, the bottom shelf in
each section should be installed with the clips at the lowest position on the pilaster strip, to provide space for sufficient airflow
under and around the product.
FIGURE 10A: Product Loading Limits
IMPORTANT NOTE: When locating your shelves, allow
space between each row of product. A minimum clearance of 2” is recommended below the bottom product
for air circulation.
Shelf clips are easily installed by inserting them into the pilasters
at the desired shelf locations. To install a shelf, simply place it
on the (4) clips, making sure that the clips are located properly,
so the shelf is level and supported at each corner. Standard and
optional heavy duty pilasters and clips are shown in Figure 10.
FIGURE 10: Standard and Heavy Duty Shelf Supports
To ensure proper air flow inside wall your cabinet, some interior
standard models are provided with product stops that snap onto
the shelves (see Figure 10B). To install the product stop, place
it over the shelf as shown and press it down onto the shelf. If
necessary, carefully pull out on the ends of the product stop,
so the bottom of the rod snaps over the shelf wire. Press down
on the hooks at ends of the product stop, so they snap over the
back of the shelf frame. Repeat for remaining shelves. Make sure
all shelves are installed with the product stops positioned at the
back of your cabinet.
FIGURE 10B: Product Stop Installation
PRODUCT LOADING
Product load should be evenly distributed over each shelf
and through the cabinet. For proper performance on standard
ceiling-mount coil models, maintain at least a 2” air space from
product to the back wall and to the coil housing. For top-mount
plug box models, a minimum 2” clearance should be maintained
from the face of the top and side walls (see Figure 10A).

SAFETY PRECAUTIONS
DISCONNECT POWER BEFORE ATTEMPTING TO WORK
ON OR CLEAN EQUIPMENT. DO NOT ATTEMPT TO
REMOVE ANY COVERS OR PARTS YOURSELF, AS
THIS CAN EXPOSE DANGEROUS, HIGH VOLTAGE
WIRING. SERVICE SHOULD ONLY BE PERFORMED BY
A QUALIFIED TECHNICIAN.
ALWAYS ROUTE POWER CORDS AWAY FROM AREAS
WHERE THEY CAN BE WALKED ON OR DAMAGED BY
OTHER EQUIPMENT. YOUR APPLIANCE IS EQUIPPED
WITH A POLARIZED, GROUNDED POWER PLUG. NEVER
ATTEMPT TO REMOVE THE GROUND POST OR USE
A NON-POLARIZED ADAPTER, WITHOUT PROPERLY
GROUNDING THE EQUIPMENT.
CONDENSER FINS ARE MADE FROM THIN METAL AND
HAVE SHARP EDGES. ALWAYS WEAR GLOVES AND
USE CAUTION WHEN WORKING ON OR AROUND THE
CONDENSING UNIT TO PREVENT CUTS AND AVOID
DAMAGING FINS, TUBING AND OTHER COMPONENTS.
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 temperature. 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.
CLEANING PRECAUTIONS
NEVER USE HARSH DETERGENTS, ABRASIVE
CLEANERS, OR CHEMICALS CONTAINING HALOGENS
(CHLORINE, FLUORINE, IODINE, ETC.) WHEN
CLEANING YOUR UNIT. CONCENTRATED CHEMICALS
CAN CAUSE DISCOLORING, ALWAYS RINSE THEM OFF
IMMEDIATELY IF CONTACT OCCURS. SEE “CLEANING
OF STAINLESS STEEL” FOR MORE INFORMATION.
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.
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 model.
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.

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 rinse, rinse, rinse
thoroughly with cool, clean, clear water.
DO NOT USE: abrasive cleaners, steel pads, wire
brushes, scrapers or knives to clean your equipment.
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.
2. CHLORIDES 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.

OPERATIONS MANUAL
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.

OPTIONAL ACCESSORIES
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.
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.

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
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.
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.
SLIDING GLASS DOOR COMPONENTS

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.)

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

REACH-INS & ROLL-INS
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.

MOUNTING CASTER SUPPORT PLATES
CASTER SUPPORT PLATES
FIGURE 14: 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.
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.
SUPPORT ASSEMBY
1/2-13 BOLT
(2 PER PLATE)
Using the small holes in the plate as a template, drill 1/8 pilot
holes in the bottom of the cabinet. (Note: drill only until you
penetrate the metal bottom of the cabinet. Do not continue
to drill into the insulation, or you may damage the cabinet.)
Secure the caster support plate assembly to the cabinet with a
sheet metal screw in each of the drilled holes. Tighten the 1/2”
bolts. Repeat these steps to attach the other plate assembly to
the opposite end of the cabinet.
Check that both plates are secure and that the casters turn
and swivel freely. Carefully lift the cabinet upright and double
check that the caster support plates are secure and the cabinet
is stable. Wait at least 3 hours before turning the refrigeration
system back on, and at least another 30 minutes for the cabinet
to come down to temperature and stabilize, before reloading
with product.
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

INSTALLATION OF TIE-IN STRAPS
FIGURE 15: Installation of Tie Straps for Roll-Thru Cabinets
Roll-Thru Cabinets
If two cabinets are installed side-by-side, a Tie-In Kit with straps
and notched upper end panels is available to attach to the cabinets for rigidity. Before installing Tie-In Strips, make sure the
cabinets are close together and each unit is properly leveled (see
Installing Roll-In and Roll-Thru Models).
Remove the front and rear grill from each cabinet, by lifting off
mounting screws on the back side at each end (screws may
need to be loosened, before grill will lift up). Remove upper end
panel on the side of each cabinet located next to an adjacent
cabinet, by loosening the mounting screws along the bottom.
Make sure the cabinets are pushed tightly together. Gap between
the cabinets must be no more ¼” wide. Position Tie-In Strap
as shown in Figure 15 across the top of the gap between the
cabinets. Re-check that the cabinets are aligned properly and
secure the Tie-In Strap to the top of each cabinet with selfdrilling screws. Position one of the notched upper end panels
as shown on the first cabinet, with the notch at the bottom, and
attach to the cabinet with sheetmetal screws at front and back
corners. Position the other notched upper end panel as shown
on the second cabinet, with the notch at bottom, and attach to
the cabinet with sheetmetal screws at front and back corners.
Reinstall the front and rear grills on each cabinet by inserting
mounting screws on the back side at each end into the keyhole
slots on the end panels. Check that the grills and doors are
straight and properly aligned. Adjust if necessary. Apply a bead
of silicone in the vertical seems between the cabinets at front
and back side.
NOTE: This is necessary to comply with sanitation
requirements and also makes it apparent that the cabinets
have been attached together.

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.
1.
2.
3.
4.
5.
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
30

8.
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 vaporizer is also
the responsibility of the installer (see “Installing Electric
Condensate Vaporizer” under “optional Accessories”).
FISH FILE MODELS
Fish File models are provided with drawers specially designed
for the storage of fresh fish, or similar product, packed in
crushed ice. Each drawer has a removable pan, with a drain
tube at the back corner (see Figure 16). Water from melting ice
in the pan, along with moisture from the product, drains out of
the storage pan through the tube, along a trough on the interior
cabinet wall, down to the sloped interior bottom, and out of the
cabinet through a 1” drain tube.
INSTALLATION AND LOCATION
In addition to normal considerations (see Installation and
Location), Fish File units should be installed directly over a
building floor drain, to rapidly dispose of water from melted ice
that drains out of the cabinet. It is also highly recommended that
your Fish File is located near a water source that can be used to
thoroughly wash down your cabinet regularly.
OPERATIONS MANUAL
NOTE: If a building floor drain is not immediately available, a waste line, with consistent downward slope, must
be supplied and connected to the 1” NPS drain tube
located under the cabinet. An electric condensate vaporizer cannot be used to dispose of water from melted ice,
as the liquid waste contains food residue that can cause
unpleasant odors and potentially unsanitary conditions.

CLEANING AND MAINTENANCE
In addition to normal cleaning, (see Periodic Cleaning
Procedure) the entire interior of your Fish File, including the
drawers and storage pans, must be thoroughly cleaned and
sanitized daily, to prevent excessive build-up of food residue,
which can cause unpleasant odors and potentially unsanitary
conditions. At the end of each day, remove any remaining food
product from the drawers and move it to suitable refrigerated
storage, or discard it.
Lift each food pan up and out of the drawer frame, being careful
not to damage the drain tube. Run the pans through a dishwasher, or properly clean and sanitize them manually. Remove each
drawer assembly by pulling it out of the cabinet, until the front
roller wheels stop against the front of the slides. Lift up the front
of the drawer, so the wheels come up and out of the slide tracks.
Pull the drawer further out, until the rear wheels stop against
the front of the slides. Lift the drawer again, so the back wheels
clear the drawer slides. Thoroughly wash the drawer frame
and components properly (see Care and Cleaning of Stainless
Steel). Carefully wash the drawer gaskets thoroughly with clean
water, dry them and check for any damage. To re-install the
drawers and pans, reverse the above procedure.
CABINET DRAIN
L.H. DRAWER SLIDE
DRAWER WHEEL
NOTE: On 2-section Fish Files, pans must be installed
with drain toward the outside cabinet wall, so the drain
tube is directly aver the drain trough.
LOADING AND STORING PRODUCT
When loading your cabinet, place a layer of ice in the drawer
pan first, then add a layer of food product, and then add another
layer of ice. Repeat this pattern until product is at least 1” from
the top of the pan, and then add a final layer of ice to cover
the product. Throughout the day, fresh ice should be added to
always keep the product covered. Periodically check the drain
tube at the back of the drawer pan and remove any debris, which
could allow excess water to accumulate in the pan. Cabinet temperature can be adjusted to approximately 36°F (2°C), to prevent
the ice from melting too quickly.
Fish should be stored at temperatures as close to 32°F (0°C) as
possible and should never exceed 39°F (4°C). Food product that
has been packed in ice must not be kept in the drawers overnight, as this can allow for elevated temperatures and excessive
thawing, which will quickly degrade product quality. Always follow proper procedures for handling, storing, thawing and cooking any type of food, to eliminate potential for any contamination
or bacteria growth.
