Ice-making stage Ice harvest stage
IMPORTANT:
? Although the unit has been tested and cleaned at the factory, due to long-term transit
and storage, the first batch of cubes must be discarded.
? Never turn off the water supply tap when the ice maker is working.
? Never touch the evaporator when the machine is running.
? Except to take ice from the unit, keep the bin door closed to reduce melting and ensure
proper ice formation.
How the Machine Makes Ice
Turn the power switch to the ON position. After about 3 minutes the machine will
automatically go into the ice-making stage.
There are two distinct cycles: freeze and harvest. During the freeze cycle, water flows to
the evaporator surface. In the harvest cycle, the ice is released and water enters the
machine. A complete cycle (freeze cycle and harvest cycle) takes 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 pumping water. When the batch of ice has
been fully formed, the ice maker stops the freeze cycle and the harvest cycle
starts.
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 off the
evaporator and into the storage bin. The freeze cycle will restart when all the
cubes drop into the bin.
How the machine uses water:
The ice maker begins with a fixed charge of water that is contained in the water tank. As
the water flows to the freezing evaporator surface, the water freezes and sticks to the ice
cube molds. During the ice-making process, fresh water enters the water tank
continuously as the water from the tank freezes continuously on the evaporator.
