Harvest Sequence
5. Water Purge
The water pump continues to run, and the water dump
valve energizes for 45 seconds to purge the water in
the sump trough. The water fill valve energizes (turns
on) and de-energizes (turns off) strictly by time. The
water fill valve energizes for the last 15 seconds of the
45-second water purge. The water purge must be at
the factory setting of 45 seconds for the fill valve to
energize during the last 15 seconds of the Water
Purge. If set at less than 45 seconds the water fill
valve does not energize during the water purge.
After the 45 second water purge, the water fill valve,
water pump and dump valve de-energize. (Refer to
“Water Purge Adjustment”) The harvest valve(s) and
HPR solenoid valve also open at the beginning of the
water purge.

6. Harvest
The HPR valve and the harvest valve(s) remain open
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 swings
the water curtain out, opening the 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.)
When Used - The air pump energizes after 35 seconds
and remains energized throughout the entire harvest
cycle. The air pump will automatically energize after
60 seconds when the harvest cycle time exceeded 75
seconds the previous cycle
