Installation Instructions
General
These instructions are of the utmost importance in
assuring that the McCall cabinet operates as
designed, and must be followed closely.
Please call your local McCall dealer or the McCall
Service Department if you have any questions
regarding proper installation.
Installing the Cabinet
When selecting a permanent location for the
cabinet, observe the following guidelines. Failure to
do so may cause reduced performance and
efficiency, cause damage, and void your warranty.
CABINET LOCATION GUIDELINES
• Install the cabinet in an indoor environment only.
• The air temperature entering the refrigerator or
freezer condenser should be between 55°F (13°C)
and 100°F (38°C).
• Allow space for air circulation in the refrigeration
condensing unit compartment on refrigerators and
freezers. The minimum space requirements are:
- 10" (25 cm) on top
- 4" (10 cm) at the back
- 4" (10 cm) on each side
• The floor must be strong enough to support the
weight of the cabinet and product load.
A fully loaded reach-in or roll-in cabinet can weigh
more than 3,000 pounds.

doorways.
1. Remove the bottom shipping skid using one of the
methods below:
- Lay the cabinet on its back, elevated and
supported by wooden blocks. Remove the skid
mounting bolts and separate the skid from the
cabinet.
- Tilt the cabinet from side to side and remove the
mounting bolts. Support the weight of the cabinet
apart from the skid.
2. Install the legs or casters and torque them to

Condensate Water Removal –
Refrigerators and Freezers
McCall cabinets are equipped with condensate vaporizer
systems.
Remote units use an electrically operated system.
Most self-contained units use energy-saving hot gas
supplied by the refrigeration system lines. No drain
connection is required.
Defrost Systems
GENERAL
Refrigerator coils are kept below the freezing point
(32°F). During compressor “off” time, the evaporator fan
continues to circulate 38°F refrigerator compartment air
through the evaporator coil. This air circulation raises the
coil temperature above the freezing point, melting any
frost that may have accumulated.
The run-off water is drained into the vapo rizer pan and is
evaporated by the hot gas refrigeration line during
compressor “on” time.
Freezer coils are defrosted electrically at userdetermined times.
NOTE: A freezer’s evaporator fans do not run
immediately upon start-up or during and immediately
following the defrost cycles. The fans start when the coil
reaches a cold temperature. This prevents th e fans from
blowing heated air on the stored products.
When the defrost cycle begins:
1. Switch 2 to 4 opens in the time clock, breaking the
circuit to the room thermostat, liquid line solenoid,
and evaporator fan motors. This allows the
compressor to pump down and shut off.
Simultaneously, switch 1 to 3 closes in the timer,
energizing the defrost heaters.
2. The heaters increase the coil temperatures above
32°F, melting the frost off the coil.
3. When the coil warms to approximately 55°F, the
defrost termination thermostat closes and energizes
the switching solenoid in the timer. At this time,
switch 1 to 3 in the timer opens, terminating the
defrost heaters. Simultaneously, switch 2 to 4 closes
in the time clock, energizing the temperature contro l
circuit.
4. Suction pressure rises, the low pressure control
closes, and the compressor starts.
5. The fan relay closes when the coil temperature
reaches approximately 30°F. This energizes the fan
motors.
6. The system operates in the refrigeration cycle until
another defrost cycle is initiated by the timer.
DEFROST SETTINGS
Set the defrost timer to defrost the reach-in during
the lowest usage periods.
Each defrost tripper represents 15 minutes of defro s t
time. At the factory, the timer is set for four automatic
defrost cycles daily at 4:00AM, 10:00AM, 4:00PM, and
10:00PM respectively. Each defrost cycle is
programmed for 45 minutes duration. Upon start-up, set
the clock for the correct time of day by rotating the clock
face until the correct time is at the arrow on the face of
the timer.
NOTE: If the defrost termination thermostat fails to
close, the fail safe setting on the timer will terminate the
defrost.
The timer starts the defrost cycle automatically at
predetermined times. A setting of two to four defrost
cycles per day is typical. For heavier frost loads,
additional cycles may be required.

Temperature Controls
REFRIGERATORS AND FREEZERS
The temperature controls are factory-set to maintain an
average temperature of 38°F in refrigerators, and an
average temperature of 0°F in freezers.
The temperature variance is 6-8 degrees. A freezer
should run between -2 to -3°F and +3 to +4°F. A
refrigerator should run between +35 to +36°F and +41 to
+42°F.
For a different cabinet temperature setting, turn the
temperature control knob, located behind the front
cabinet louver.
Setting the temperature control to the coldest setting
may cause the coil and/or air ducts to freeze and ice
up. This will eventually result in a warmer cabinet
temperature.
If ice accumulation occurs and the temperature is
lower than the guidelines, turn the control knob to a
warmer setting.
Allow the reach-in to reach proper operating
temperature before filling it with product. Do not
place hot or steaming foods in the cabinet.
REACH-IN
Single-section reach-in heated cabinets are designed to
maintain a temperature of up to 170°F. Two-section and
three-section cabinets can maintain a temperature of up
to 140°F.

Loading Shelves – Reach-in Cabinets
For maximum operating efficiency, load the shelves with
space between the stored items. This allows air to
circulate properly. Refer to the drawing below.
Do not store more than 250 pounds of product on
any shelf, and no more than 800 pounds of product
per cabinet.
Store products with high acid content (such as
lettuce, other fresh vegetables or fruits, salad
dressings, etc.) in closed containers. This will
prevent corrosion on the evaporator coil and other
metal parts in the air distribution system.
Uncovered food will dehydrate much more rapidly
than covered food. For best food quality, always
store in covered container.
Loading Carts – Roll-in Cabinets
Roll-in cabinets are designed to accept carts of preheated food (heated units) or pre-chilled or frozen food
(refrigerators or freezers).
Cart guides have been installed in each cabinet bay to
keep the cart away from the interior walls. Center the
cart(s) in the bay(s) for best air circulation. Refer to the
drawing below.

Cleaning Recommendations
EXTERIOR
Clean cabinet exterior surfaces with a solution of mild
soap and water. To minimize streaking, follow with a
fresh water rinse.
If stainless steel becomes discolored, scrub only in the
direction of the finished grain.
For high shine, see your kitchen equipment dealer for a
high-quality stainless steel polish.
Do not use steel wool, caustic soap, or abrasive
cleaners, as these may damage the metal finish.
Alcohol-based cleaners may damage the nylon door
cams.
INTERIOR
Clean cabinet interior surfaces with warm water and
baking soda, applied with a cloth or sponge.
The air duct and shelf support standards can be
removed without special tools to facilitate cleaning.
Wash door gaskets weekly with a mild soap and water
solution, followed by a fresh water rinse.
While cleaning, check the door gaskets for proper
sealing. Adjust if needed.
Never use cleaners that are not approved for use
where food may come into contact with cabinet
interior surfaces.
Do not use steel wool, caustic soap, or abrasive
cleaners, as these may damage the metal finish .

Cleaning the Condenser Coil –
Refrigerators and Freezers
Disconnect electric power before cleaning.
For efficient operation, it is very important to clean the
condenser coil surface and keep it free of dust, dirt, and
lint. McCall recommends checking the condition of the
condenser coil once a month.
The condensing unit fan draws dust, lint and small
particles to the condenser coil, where it forms a “blanket”
on the coil surface. This is normal and should be
periodically removed.
Failure to clean and maintain the condenser coil
properly will result in reduced air circulation through
the condenser fins. This will cause reduced
efficiency, high operating pressures, and possible
shortened compressor life.
Method 1
Remove light build-up with a soft brush or a vacuum with
a brush attachment. Brush the condenser fins from top
to bottom, not from side to side. Shine a light through the
fins to check for dirt inside the condenser.
Method 2
Clean moderately dirty fins with compressed air, blowing
from the inside out. Follow by brushing, if necessary.
Method 3
Clean with a commercial condenser coil cleaner,
available from a kitchen equipment dealer. Follow the
directions and precautions supplied with the cleaner.
After cleaning, straighten any bent condenser fins with a
fin comb.
CONDENSER CLEANING PROCEDURES
One or more of the following methods may be used to
clean the condenser coil surface, depending upon the
extent of the build-up on the fins.
Condenser fins are sharp. Use care when working
around them.
Using a Fin Comb
CLEANING THE FAN BLADES AND MOTOR
If necessary, clean the fan blades and motor with a soft
cloth. If it is necessary to wash the fan blades, cover the
fan motor to prevent moisture damage.
