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).
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.
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
UNCRATING YOUR NEW MODEL
IMPORTANT: Your equipment should never be transport-
ed 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.

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.
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
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
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
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.

REACH-INS & ROLL-INS
SITE PREPARATION
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.
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.
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.
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-
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.
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 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.
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.
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.

ELECTRIC VAPORIZER WITH WATER LEVEL SWITCH
REACH-IN CABINET
REACH-IN/ROLL-IN DOOR COMPONENTS
HALF DOOR SHOWN
(COMPONENTS TYPICAL)
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.
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 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 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.
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.

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.
REACH-INS & ROLL-INS
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.
OPERATIONS MANUAL

REACH-INS & ROLL-INS
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
MODIFICATIONS TO YOUR EQUIPMENT CAN CAUSE A
HAZARD AND WILL VOID 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 voltages,
connections should be made as required on the electrical wiring
diagram provided next to the electrical control box.
START-UP CHECKLIST
After your unit has been installed and electrically connected in
accordance with this manual, please take time to check the following before loading product, to assure trouble-free operation:
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).
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.
CAUTION: IF UNIT IS UNPLUGGED OR DISCONNECTED

OPERATIONS MANUAL
REACH-INS & ROLL-INS
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.

Press here to decrease temp.
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.
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 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
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 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.
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.
WARMER SYSTEM AND ADJUSTMENT
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
/ DRAIN PAN
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.
