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.

Inlet Water Solenoid Valve Harvest Cycle Water Schematic
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.
