Set the ON/OFF button to the ON
position. The machine will automatically
go to the ice making stage.
There are two distinct cycles: ice freeze
and harvest.
The freeze cycle happens when water
flows to the evaporator surface. The
harvest cycle is when the ice is released
and water enters the machine. A
complete cycle takes about 20 minutes,
but it depends on temperature and
operating conditions.
freeze: During the freeze cycle the
compressor is pumping refrigerant, the
fan motor is blowing air, and the water
pump is circulating water. When the
batch of ice has been fully formed, the
ice maker stops the freeze cycle and the
harvest cycle begins.

Harvest: During the harvest cycle the
compressor is still operating, but the
water pump has stopped. The hot gas
valve opens, diverting hot refrigerant
gas into the evaporator. The hot
refrigerant gas warms the evaporator,
causing the cubes to slide as a unit off
the evaporator and into the storage bin.
The freeze cycle will restart when all the
cubes have been harvested.
How the machine uses the water
The ice maker begins with a fixed
charge of water that is contained in the
water trough. As the water flows to the
freezing evaporator surface, the portion
of water that does not contain mineral
impurities freezes and sticks to the
ice cube molds. The water containing
impurities falls back into the water
trough. During the ice making process,
fresh water enters into the water trough
continuously as the water in the trough
freezes continuously in the evaporator.
