Water System
The water system consists of a water pump, inlet
water solenoid valve, reservoir with overflow
standpipe and spray platform.
Harvest cycle: The inlet water solenoid valve is
open during the harvest cycle. Water flows through
it to the top of the machine and onto the evaporator
platen. The water flows across the platen, warming
it up to assist in releasing the ice. Water drains
from the platen through drain holes at the platen
corners. That water, now chilled by contact with the
evaporator platen, drains into the reservoir. When
the reservoir is full, excess water drains out the
standpipe. When harvest is complete, the inlet
water solenoid closes and water stops flowing into
the machine.
Freeze cycle: The water pump takes water from
the reservoir and forces it through the 6 spray jets,
causing the water to contact the inverted cups of
the evaporator. Unfrozen water falls back into the
reservoir. As ice forms in the cups, the water level
in the reservoir fails. This continues until the
harvest cycle starts.
