Harvest Sequence
5. Water Purge
The air pump(s) (when used) and the harvest valve(s)
open at the beginning of the water purge to divert hot
refrigerant gas into the evaporator.
The water pump(s) continues to run, and the water dump
valve energizes to purge the water in the water trough.
6. Harvest
The air pump (when used) remains energized and the
harvest valve(s) remains open. 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.)
