CLEANING INSTRUCTIONS
CLEANING THE CABINET EXTERIOR
Wipe the exterior occasionally with a cloth dampened in
mild detergent water; rinse, and wipe dry with a soft,
dry cloth. Do not use abrasive or caustic cleaners or
scouring pads.
CLEANING THE CONDENSER
Periodic cleaning of the condenser can be easily
accomplished by brushing the coils with a soft brush
and/or using a vacuum cleaner with a brush attach-
ment.
Be sure that dirt, dust, and a collection of other debris
do not build up to a point that air circulation through the
condenser is restricted.
CLEANING THE STORAGE COMPARTMENT
1. Remove product and store it in another suitable cab-
inet, if possible. Be sure to prevent spoilage of the
product which may occur if it is left at room temper-
ature.
2. Turn OFF the thermostat and unplug the cabinet.
3. Defrost completely prior to cleaning.
4. Wash the entire interior storage area with warm
water and baking soda solution — about a table-
spoon of baking soda per quart of water. Rinse thor-
oughly with clean water and wipe dry.
5. A drain hose is provided. Connections are made to
fit a standard garden hose for ease of draining water
from inside of the tank area.
IMPORTANT:
Do not use any objects or cleaners which may leave
residues, odors, or particles. Avoid the use of strong
chemicals or abrasive cleaners which may damage the
interior surfaces and contaminate product within the
storage area.
6. Be sure to correctly plug in to cabinet, set the tem-
perature control, and allow time for cooling of the
storage area before storing product.
DESCRIPTION OF REFRIGERATION
SYSTEM: CONDENSING UNIT
All CMCT cabinets are equipped with Copelametic
compressors utilizing 404A refrigerant:
1/2 HP on the CMCT-4 and CMCT-6
3/4 HP on the CMCT-8
1 HP on the CMCT-10
A back pressure valve is used to protect the compres-
sor against excessive pressures during initial cabinet
start-up and upon termination of the defrost cycle. This
valve is factory pre-set to limit the crankcase pressure
to 10# and should not be changed.
CABINET OPERATION
REFRIGERATION CYCLE:
Refrigeration is accomplished by both a “wrap-around”
tank coil and fin coil. This tank coil consists of several
passes of copper tubing wrapped completely around the
tank or product compartment. The fin coil located behind
the light fixture serves two purposes — it creates a blan-
ket of cold air over the product and collects moisture in
the form of frost from the warm air entering the cabinet,
thus reducing frost collection on the tank coil. The refrig-
erant enters the top of the tank coil first and progresses
downward to the bottom of the tank; from there it enters
the top of the fin coil and again downward. By circuiting
the refrigeration in this manner, it assures the fin coil of
being the coldest part of the system.
DEFROST CYCLE:
Because of the large size and fin arrangement, the
CMCT fin coils have the ability to collect a large amount
of frost before becoming blocked. These features permit
the CMCT cabinets to operate on one defrost cycle per
24 hours, thus reducing product shock to the ice cream.
The fin coil and drain pan are defrosted with one 4-
pass heater located on the underside of the evaporator
assembly. The back pass of the heater lays in the drain
trough which slopes from left to right along the back
edge of the drain pan.
WARNING:
To avoid the possibility of an electrical shock, turn OFF
thermostat and unplug the electrical cord of the cabinet
before cleaning or touching electrical connections or parts.
