FREEZING CYCLE OPERATION
Water from the sump assembly is pumped to the
water distributor system at the top of each
evaporator plate. From the water distributor the
water cascades by gravity over all cells of the plate
and to the sump assembly below.
At the beginning of the freezing cycle, the electrical
circuit is completed to the compressor and the
water pump. The water pump operates
continuously, through both the freezing cycle and
the harvest cycle.
During the freezing cycle, the hot gas solenoid
valve and the water inlet solenoid valve are
CLOSED. When the ice cubes are partially
formed, the cube size control (sensing bulb
attached to the suction line) will CLOSE, and
connect power to the timer motor. The timer then
controls the remainder of the freezing cycle. The
timer will keep the ice maker operating in the
freezing cycle for a selected length of time. This
will give the ice cubes time to fully form. after
which, the timer will switch the ice maker into the
harvest cycle, through the contacts of the timer
assembly microswitch.
