CS55 HOW IT WORKS:
COMPONENT DESCRIPTION
Cube Size Control
The cube size control is located in front of
the control box, behind the front panel.
The sensing capillary tube of the cube size
control is routed out of the control box into
its bulb holder on the evaporator coil. It is
a reverse acting temperature control with
double throw contacts. Turning its knob all
the way counterclockwise also shuts off the
icemaker.
The control determines the length of the
freezing cycle and correspondingly the size
of the cube. A lower setting will produce a
smaller cube, and a higher setting will
make a larger cube. The cube size control
changes its contacts when the evaporator
reaches its preset temperature, starting the
harvest cycle. When the sensing tube of
the cube size control reaches the high
preset temperature, the contacts change
again, restarting the freeze cycle.
Compressor Toggle Switch.
The compressor toggle switch is located on
the side of the control box. When moved
to the ON position, it makes a circuit to the
compressor. When moved to the OFF
position, the other components will still
operate.
Water Pump
The water pump operates during the
freezing cycle only, pumping water through
the spray nozzles into the inverted spray
cups.
Inlet Water Solenoid Valve
The water solenoid valve, located in the
back panel of the unit, is energized only
during the harvest or cleaning cycles.
When energized it allows a metered
amount of water to flow into the machine
(.21 g.p.m.) This water flows to the top of
the evaporator and then down into the
reservoir.
Water Purge Drain Valve
The purge valve opens during the harvest
cycle, and when the pump is on, water
from the pump discharge is diverted to the
drain. This flushes out the reservoir.
Bin Thermostat Control
The bin thermostat control body is located
in front of the control box just beside the
cube size control. The thermostat sensing
tube is located in the ice storage bin on the
left side wall where is automatically shuts
the icemaker off when the bin is full and
restarts when ice is removed. Factory
settings are 1 degree C (36 degrees F) cut
out and 4 degrees C (39 degrees F) cut in.
It can be adjusted by turning the
adjustment screw visible through the
control box cover.
Hot Gas Valve Assembly
The hot gas valve assembly is comprised
of two parts, the valve body and the coil.
These parts are located on the discharge
line of the compressor and are activated by
the cube size control (harvest cycle).
When the coil of the hot gas valve is
energized, it magnetically lifts the plunger
in the hot gas valve body. This allows hot
refrigerant gas to by-pass the condenser
and go directly to the evaporator.
Spray Platform and Chute
The spray system used on this unit is of
the stationary type. The water is forced by
the water pump into the platform chamber
and sprayed into the inverted cup molds
through a set of six spray nozzles.
Fan Motor
The fan motor is electrically connected
through the cube size control and runs only
during the freezing cycle.
Hermetic Motor Compressor
The compressor is a vapor pump, forcing
refrigerant gas throughout the refrigeration
system.
