•

Water Pump - on when the pump is

•

Purge Valve - on when the purge valve is

•

Water Solenoid - on when the inlet water solenoid

valve is

•

Hot Gas - on when the vapor inlet valve and

harvest assist solenoid / mechanism have power

•

Compressor - on when the compressor contactor

is energized

•

Ready to Harvest - on when the ice thickness

sensor has water touching it

•

Sump Empty - on when there is no water touching

the mid-length probe

•

Sump Full - on when water is touching the

shortest probe

•

SW2 - on when the curtain is open

•

SW1 - on when the curtain is open

Cycle Definitions:

Freeze: The refrigeration system is operating to

remove heat from the evaporators. The compressor,

fan motor, and water pump are on.

Harvest: The refrigeration system and water system

are operating to harvest the ice and rinse the

reservoir. The compressor is on for the full cycle, the

pump is on until the purge valve closes.

The inlet water valve opens and refills the reservoir.

The vapor and condenser by-pass valves are open

during the entire harvest cycle, as are the harvest

assist mechanisms.
