prechill the evaporator.
e) Freeze
：
water pump is energized to make ice in the evaporator.
2) Harvest cycle
f) energy storage
：
when the harvest probe doesn’t contact the water
，
condenser NTC probe test the liquid tube temperature and give the time to
stop the condenser fan before harvest, to add the heat of the refrigeration
system. Increase the harvest effective.
g) Harvest cycle
：
hot gas valve is energized to heat the evaporator
，
when
the surface of ice begin to melt, the ice will drop down by the gravity. And
the ice put the water curtain outside and the magnet switch from close to
open to close, harvest cycle ended to return the prechill cycle and start next
step.
h) Ice full
：
when the magnet switch opens beyond 30s in harvest cycle, the
ice machine stops, mean the ice is full.

1) When need to adjust the ice thickness, screws the water probe to change the
water level position. screw the adjustable nut clockwise, increase the ice
thickness; turn the adjustable nut counterclockwise, and reduce the ice
thickness.
