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.)
Automatic Shut-Off
7. Automatic Shut-Off
When the storage bin is full at the end of a harvest
sequence, the sheet of cubes fails to clear the water
curtain/ice damper and will hold it open. After the
water curtain/ice damper is held open for 30 seconds,
the ice machine shuts off. The ice machine remains off
for 3 minutes before it can automatically restart.
The ice machine remains off until enough ice has been
removed from the storage bin to allow the ice to drop
clear of the water curtain/ice damper. As the water
curtain/ice damper closes the bin switch the ice
machine restarts (steps 1 - 2) provided the 3 minute
delay period is complete.
