Serial Number Location
The serial number is located on either the right side interior back
wall or under the top nosing directly above the right door.
Always have the serial number of your unit available when calling
for parts or service. A complete list of authorized McCall parts
depots is on www.mccallrefrigeration.com.
This manual covers standard units only. If you have a custom
unit, consult the customer service department at 1-888-7322446

Receiving And Inspecting The Equipment
Even though most equipment is shipped crated, care should
be taken during unloading so the equipment is not damaged
while being moved into the building.
1. Visually inspect the exterior of the package and skid or
container. Any damage should be noted and reported to
the delivering carrier immediately.
2. If damaged, open and inspect the contents with the
carrier.
3. In the event that the exterior is not damaged, yet upon
opening, there is concealed damage to the equipment
notify the carrier. Notification should be made verbally
as well as in written form.
4. Request an inspection by the shipping company of the
damaged equipment. This should be done within 10 days
from receipt of the equipment.
5. Check the lower portion of the unit to be sure legs or
casters are not bent.
6. Be sure to check the compressor compartment housing
and visually inspect the refrigeration package. Be sure
lines are secure and base is still intact.
7. Freight carriers can supply the necessary damage forms
upon request.
8. Retain all crating material until an inspection has been
made or waived.

Installation
Location
Units represented in this manual are intended for indoor use
only. Be sure the location chosen has a floor strong enough to
support the total weight of the cabinet and contents. Reinforce the
floor as necessary to provide for maximum loading.
For the most efficient refrigeration, be sure to provide good air
circulation inside and out.
Inside cabinet: Do not pack refrigerator so full that air cannot
circulate.
Outside cabinet: Be sure that the unit has access to ample
air. A minimum space of 3” (7.6cm) at the back of the unit
and 1” (2.5cm) at the top and sides is required to conform to
Underwriters Laboratories’ standards. On undercounter units it is
imperative that the proper air flow be maintained. The refrigeration
system is designed so air will flow under the unit, over the
compressor/condenser area, and out at the top rear of the unit.
Avoid hot corners and locations near stoves and ovens.
Any restriction of the proper air flow outlined
above, total or partial, will void the warranty on
the unit.
Leveling
A level cabinet will perform better because the drain pan will drain
properly, the doors will line up with the frames and the cabinet will
not be subject to undue strain.
All four legs are adjustable. Adjust each leg until the unit is stable
and level left to right. If necessary adjusting the front legs slightly
higher than the rear by about 1/8” (0.3cm) will help the doors
remain closed.
If the unit is supplied with casters, no adjustments are available.
Ensure the floor where the unit is to be located is level.
Never stand on the unit! Doing so may result in bodily
injury. They are not designed to hold the weight of an
adult and will collapse if misused in this manner.
Stabilizing
Some models are supplied on casters for your convenience, for
ease of cleaning underneath and mobility.
The unit must be installed in a stable condition
with the front wheels locked. Locking the front
casters after installation is the owner’s and operator’s
responsibility.
Plumbing
Self-contained models are standard with a condensate evaporator.
If, for some reason, a unit does not have a condensate evaporator,
or the evaporator fails, the unit’s drain must have an outlet to an
appropriate drainage area or container.
Moisture collecting from improper drainage can
create a slippery surface on the floor and a hazard to
employees. It is the owner’s responsibility to provide
a container or outlet for drainage.
Electrical connection
Refer to the amperage data on page 3, the serial tag, your
local code or the National Electrical Code to be sure the unit is
connected to the proper power source. A protected circuit of the
correct voltage and amperage must be run for connection of the
line cord, or permanent connection to the unit.
A 7’ (2.1 m) long grounded supply cord and plug are provided
with standard units. Simply plug the unit in to begin operation.
The thermostat must be turned to OFF and the unit
disconnected from the power source whenever
performing service, maintenance functions or
cleaning the refrigerated area.

Operation
Compact Refrigerators and Freezers Service and Installation Manual
After the unit is connected to power it will automatically begin
operating. With the doors closed, the temperature of the
cabinet should reach 36°F to 40°F (2°C to 4°C) on refrigerators
or 0°F (-18°C) on freezers in about one hour.
Temperature control instruction
Refrigerators: A thermostat located in the evaporator housing
on interior rear of the unit, controls the temperature in the box.
The factory setting for the control is “4” and maintains about
38°F (3°C) in the box. Set toward “1” for higher temperatures
Door Maintenance
Adjusting door hinges
Doors have been adjusted at the factory. If it becomes
necessary to adjust a door, follow these instructions:
1) If the door needs lowering at the handle, use a 5/16” wrench
to loosen the hinge screws and install a spacer outside of
the hinge (see illustration 1). Tighten the screws.
2) If the door needs to be higher at the handle, use a 5/16”
wrench to loosen the hinge screws and install a spacer
inside of the hinge (see illustration 2). Tighten the screws.
and toward “7” for lower temperatures.
Freezers: A thermostat located in the evaporator housing on
interior rear of the unit, controls the temperature in the box.
The factory setting for the control is “4” and maintains about 3°F (-18°C) in the box. Set toward “1” for higher temperatures
and toward “7” for lower temperatures.
Continuous opening and closing of the doors will hamper the
unit’s ability to maintain optimum refrigeration temperature.
Defrosting
Refrigerators
Refrigerators defrost automatically with every cycle of the
compressor. The water generated is routed to a pan on the
rear of the unit and is evaporated by the heat given off by the
compressor.
Freezers
When defrost control goes into defrost, power to the condensing
unit and evaporator fans is interrupted and the defrost heater
is energized. The defrost heater warms the evaporator coil
thereby melting all frost accumulated during the previous
For customer service, call (888) 732-2446, Fax (800) 669-0619, www.mccallrefrigeration.com
refrigeration cycle. Once all frost is eliminated, the temperature
of the coil continues to rise until it reaches 27 minutes. The
defrost control switches to refrigeration mode. Defrost will
initiate every six hours.
Turn the screw ONLY in a clockwise direction,
turning the screw counter-clockwise will break
the cam motor.
