How the Machine Makes Ice
Turn the ICE/OFF/WASH switch to the ICE position. The machine will automatically start the ice
making stage. There are two distinct cycles: freeze and harvest. During the freeze cycle, water flows
across the evaporator surface to form the ice. In the harvest cycle, the ice is released. A complete
cycle can take 15 to 40 minutes, depending 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 begins the harvest cycle.
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 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. During the
ice-making process, fresh water enters the water trough continuously as the water from the trough
freezes on the evaporator.
