RECEIVING YOUR NEW MODEL
Congratulations on your recent purchase of continental refrigerator superior food
equipment products! When your shipment arrives, please thoroughly examine the
shipping crate for any punctures, dents, or signs of rough handling. It is in your best
interest to partially remove or open the shipping container in order to examine the
model for any concealed damages which may have occurred during shipment. If the
model is damaged, it must be noted on the delivering carrier's delivery slip or bill of
lading (see “filing a damage claim” under warranty section).
GENERAL INFORMA
TION 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 all of the material in order to
become more familiar with your equipment and its operation, and enjoy optimum
performance.
Important Note: All value and designer line freezers have an energy-saving fan
delay control to prevent the interior fans from operating until the evaporator coil
becomes chilled. Therefore, on initial start-up, the fans will not turn on immediately.
This is a normal mode of operation. Allow sufficient time for the evaporator coil
to reach its operating temperature (approximately 20 minutes).
No floor drains or plumbing connections are required since all models are completely
self-defrosting and use an automatic defrost condensate water evaporating system
(see “condensate evaporator installation” under installation and location section).
All cabinets must be given sufficient time to reach normal operating temperature
before placing any food inside. For refrigerators, approximately 2 hours of operation
are required to lower the cabinet temperature to 40°F. Freezers require approximately
4 hours of operation to lower the cabinet temperature to 0°F (see “operation” section
for further information).
Never
overload top shelf with product so as to block or restrict cabinet airflow. Doing
so will result in poor performance, decrease in efficiency and possible need for service
to de-ice evaporator.
Prior to factory shipping, all models are performance run tested for a minimum of 12
hours providing a highly sophisticated temperature analysis recording exclusive to
each individual cabinet. This recording is supplied within this manual packet. A final
leak check, vibration, noise level and visual examination is made by a qualified quality
control team to assure a quality product. The carrier signs to this effect when he
accepts the product for shipping. To insure the maximum in safety and sanitation, all
models are listed under the reexamination service of underwriter's laboratories and
with the national sanitation foundation.

UNCRATING YOUR NEW MODEL
The shipping container should remain on your model as protection against dents
or scratches while transporting it to the actual set-up location. Remove the shipping
container only at the last possible moment by following these simple steps:
1. Using a pry bar, pry off and remove crate end bottom staples.
2. Pry off and remove crate front and rear bottom staples.
3. Slide crate upward and remove it, being careful not to rub against cabinet.
There are up to four (4) bolts securing 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 it is
advisable to tilt the cabinet backwards and place wooden blocks at each end in order
to hold it in its tilted position. Using a
3
/4" socket or open end wrench, remove the bolts
and carefully slide the model off of the skid. After skid removal, the cabinet should
never be moved without dollies or rollers to avoid damage to the cabinet bottom or
floor.
Important Note: Do not under any circumstances lay your new model on its front
or sides. Only for a brief period, may you lay the model on its back and only then,
when its properly blocked so as not to crush the condensate drain tubing and also
to allow provision for your hands in order to set it in its upright position without
inflicting damage to 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 damage
could result to the compressor.
INSTALLATION AND LOCATION
CLEARANCES
Before moving the cabinet to its final point of installation, accurately measure all doorways or passages to assure clearance. If additional clearance is needed, cabinet doors
and grill can be easily removed (see instructions outlined in “removal of doors” and
“removal of grill” sections).
VENTILATION
The final location site of your air cooled refrigerator or freezer must be able to provide
a large quantity of cool, clean air. The refrigeration system operates most efficiently
and trouble-free with cool, dry air circulation. Avoid locations near heat and moisture
generating equipment such as stoves, ovens, cooking ranges, fryers, dish washers,
steam kettles, etc., and also direct sunlight where temperatures can be in excess of
100°F. Also, do not select a location in an unheated room or area where temperatures
may drop below 55°F. Air supply to the condensing unit is equally important. Restricting
the air supply will place an excessive heat load on the condensing unit and adversely
effect its operating efficiency.

Important Note: To assure sufficient air supply and circulation to the condensing
unit, a minimum clearance of 12" above the grill and 3" on each side and back of the
cabinet must be provided (see figure 1). If necessary, special venting or air supply
ducts must be installed by the installer for this purpose. Do not at any time obstruct
the grill area in front of the cabinet in any way, and never place or store anything on
top of the cabinet machine compartment. These rules are essential for maximum
cooling capacity and long life of refrigeration parts.
FIGURE 1
MINIMUM CLEARANCE DIMENSIONS
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. A fully loaded reach-in or roll-in model may reach
2,000 - 3,000 pounds. To estimate the possible product load 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 and obtain the product load weight.
For example, a 20 cubic foot refrigerator can hold approximately 700 pounds of
product (35 x 20) and assuming the refrigerator itself weighs 300 pounds, the total
combined weight of cabinet and product is approximately 1000 pounds. Therefore,
the floor in this example must be capable of supporting up to 1000 pounds.

INSTALLING LEGS AND LEVELING REACH-IN MODELS
Your new reach-in model is supplied with adjustable type legs for leveling purposes.
Each single and two section model has four leg mounting holes on its case bottom,
and three section models have six leg mounting holes. Legs are packed in the
accessory carton from which they must be removed and installed on the cabinet
case bottom (see figure 2). In order to install the legs, carefully tip the cabinet
8
Your roll-in model comes with one cart ramp per door opening. To install the ramp(s),
simply open the cabinet door and position the ramp slots onto the screws located
along the cabinet bottom front. If the door wiper rubs along the ramp to the extreme
where the door will not self-close, you will need to adjust the door (see “door adjustment” section) or level the cabinet as explained above.
Important Note: It is extremely important that your new reach-in or roll-in model is
perfectly level for proper operation. If it is not level, the following adverse conditions
will become apparent:
1. The door(s) will not be properly aligned and consequently will not provide a
good seal. Roll-in door wiper(s) may bind.
2. Your model will run excessively due to improper door seal(s).
3. An excessive amount of ice will accumulate inside the cabinet, around the
door opening(s) and especially on the finned evaporator coil. If allowed to
continue, ice will eventually block the coil and the model will fail. This will
result in the loss of all food stored within the cabinet.
4. Defrost water will fail to drain properly and will overflow the evaporator coil
drain pan and into the cabinet of both refrigerator and freezer models.
INSTALLING CASTERS AND LEVELING REACH-IN MODELS
If you wish to install casters on your new reach-in model, follow the steps above
for “installing legs” to install the casters, making sure again that the casters are
tightened extremely well (see figure 3). If the casters are not installed tightly, the
cabinet will sway or rock with each opening or closing of the doors, possibly causing
damage to the case bottom.
To assure that your cabinet is level, caster cups must be installed under the casters
which need leveling. Caster cups are not provided with your new model but can be
purchased at most hardware or furniture stores. Do not attempt to level casters by
unscrewing them from the case bottom as this will cause damage to the cabinet
bottom and leg hole threads, voiding all warranties.

INSTALLING CONDENSATE EVAPORATOR
No floor drains or plumbing connections are required since all
models use an
automatic condensate water evaporating system. All designer line models utilize
a unique hot gas condensate water evaporating system which is completely selfcontained and no further assembly or maintenance is required (these models are
recognized by their evaporator coil which is located out of the food zone in an
insulated plug-box housing next to the condensing unit). All value line models are
supplied with an electric condensate evaporator pan and mounting bracket packed
in the accessory carton. To install the condensate pan on value line models only,
remove both mounting screws located on the bottom of the cabinet back and install
the mounting bracket on the case bottom as shown in figure 4. Slide the condensate
pan onto the bracket, install the drain tube into the pan making sure it is not blocked
or kinked, and plug the ten foot power cord into the receptacle labeled “vaporizer”
located on the case top electrical box.
IMPORTANT NOTE: It is extremely important to be sure that the condensate
pan is plugged into its correct receptacle labeled “vaporizer” and that the condensing unit is plugged into its correct receptacle labeled “condensing unit”.

REMOVAL OF DOORS AND DOOR ADJUSTMENT
During installation, it may become necessary to remove the cabinet doors to
facilitate passage through narrow doorways or hallways. To remove a door, pry
off all hinge covers using a sharp tool or knife (see figure 5). Swing the door to
the open-door position (90°) and carefully lift the door upward, removing the
door from the hinge bodies. If it is necessary to remove the hinge bodies from
the cabinet face, be extremely careful not to lose the light switch pin located inside
all top hinge bodies. To reinstall the door, reverse the above procedure.
All doors have been aligned at the factory, however vibration during transportation
may cause doors to shift and realignment may be necessary. If the door(s) require
realignment, proceed as follows:
1. Pry off all hinge covers using a sharp tool or knife.
2. For each door, loosen the screws which secure the hinge bodies to the
cabinet face and slide the door into alignment. Hold the door firmly in place
and tighten all screws securely.
If the door gasket(s) do not seal properly to the cabinet face and there are gaps
between the gasket and the face on the hinge edge, proceed as follows:
1. For each door, loosen all screws which are directed into the edge of the
door and push the door towards the cabinet eliminating the gap. Hold the
door firmly in place and tighten all screws securely.
2. Replace all snap-on hinge covers.

DOOR ADJUSTMENT AND REMOVAL
REMOVAL OF GRILL
To remove the grill, loosen all four (4) grill mounting screws located on the backside
of the grill one or two turns. 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 on the grill and down.
Important note: If the model is provided with a digital or dial thermometer, the
front grill cannot be completely removed from the cabinet without first removing the
thermometer bulb from inside the cabinet. However, enough capillary tubing and/or
wiring cable has been provided to allow the grill to be laid across the top of the
cabinet after it has been removed. Take care not to damage the capillary tubing
when handling the grill.
If it is necessary to remove the thermometer bulb from inside of the cabinet,
first locate the thermometer bulb cover and remove the thumbscrews securing
it in place. On value line models, the thermometer bulb cover is located on the
interior top left corner towards the front of the cabinet. On designer line models,
the thermometer bulb is located on the interior top under the air duct. Once the
cover is removed, 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 permagum sealant
around the hole after inserting the bulb.
INITIAL
CLEANING PROCEDURE
Prior to start-up and before placing any food inside of your new reach-in or roll-in
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 the maintenance section.

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 upper cabinet end panel next to the electrical console
box, should also be consulted during connection.
Important Note: The condensing unit supplied with all self-contained models is
designed to operate with a voltage fluctuation of + 10 % of the voltage indicated on
the cabinet serial data plate. Full voltage of the correct service, on an individual line
not affected by the operation of other electrical appliances, must be available to the
condensing unit at all times. Burnout of the compressor due to exceeding the
high or low voltage limits is easily detected and will automatically void the
factory warranty.
115 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115 volt models are provided with a U.L. approved power cord and polarized plug
which is factory installed.
Warning: Any alterations to this cord and plug could cause an electrical
hazard and will void the factory warranty.
To insure proper operation, this equipment must be plugged into a NEMA 5-15R
compatible, grounded receptacle that can supply the full voltage as stated on the
serial data plate.
208-230 VOLT, 60 HZ, 1 PHASE CONNECTION
All 208-230 volt models are to be permanently connected and are provided with
four (4) field wiring leads which exit the electrical console box located in the
machine compartment behind the front grill. The cabinet circuitry is 115 volts
and the condensing unit is 208-230 volts in which the wiring includes a neutral
and a mechanical ground. This wiring should be connected to the appropriate
power source by a qualified electrician and must conform to all local electrical
codes.
SPECIAL VOLTAGE CONNECTIONS
When models are ordered from the factory with special, optional voltages, connections
should be made as required on the electrical wiring diagram provided on the upper
cabinet end panel next to the electrical console box.
