Harvest Sequence
5. Water Purge
The air pump (when used) the harvest valve(s) and
harvest pressure regulating valve (HPR) energize to divert
hot refrigerant gas to the evaporator.
The water pump continues to run, and the water dump
valve energizes to purge the water in the water trough.
6. Harvest
The harvest valve, air pump(s) and harvest pressure
regulating (HPR) solenoid valves remain energized and
the refrigerant gas warms the evaporator causing the
cubes to slide, as a sheet, off the evaporator and into the
storage bin. The sliding sheet of cubes opens the water
curtain/ice damper and bin switch. The momentary
opening and re-closing of the bin switch terminates the
harvest sequence and returns the ice machine to the
freeze sequence (Step 3 - 4.)
