HARVEST CYCLE - HOT GAS BYPASS
When the timer switches the ice maker into the
harvest cycle, high pressure, high temperature
refrigerant gas being discharged from the
compressor is diverted from the condenser
through the hot gas solenoid valve into each
evaporator plate. During this cycle, the refrigerant
bypasses the condenser. In the electrical circuit,
both the compressor and the water pump are
operating and the hot gas solenoid valve is
energized and OPEN and the water inlet solenoid
valve is OPEN. The finished ice cubes are released from the sides
of each evaporator plate by the warming effect of
the hot gas condensing in each evaporator plate
and the water cascading over the ice cubes. The
released ice cubes drop into the ice storage bin
below. At the end of the harvest cycle, the timer
cam will push the actuator arm to the micro switch
IN. If the ice level control is still CLOSED, a whole
new cycle will begin. If the ice level control is
OPEN, the ice maker will begin to shut OFF.
