6. HARVEST
The harvest valve(s) remains open and the refrigerant gas warms the evaporator. This causes 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. This momentary opening and closing of the bin switch terminates the Harvest Cycle and returns the ice machine to the Freeze Cycle (steps
The air compressor (when used) remains energized throughout the entire harvest cycle. The air compressor will automatically energize after 60 seconds when the harvest cycle time exceeded 75 seconds in the previous cycle.
