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 the water supply tap off when the ice maker is working.
Never touch the evaporator when the machine is running.
Except to take ice from the unit, keep the door closed to reduce melting and insure
proper ice formation.
How the Machine Makes Ice
When the power switch is first turned ON, the machine is in Stand-by mode. After about
3 minutes, it will automatically proceed to 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 can take 15 to 40 minutes, depending on ambient
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, power is supplied to
the water purge valve and hot gas valve. The water purge valve opens and
allows the water pump to purge the water remaining in the water tank,
removing all impurities and sediment. This allows the machine to make clear
ice cubes and keep mineral build-up at a minimum. Then the water pump
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 drop into the bin.
How the machine uses water:
The ice cube machine 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 will freeze and
stick to the ice cube molds. During the ice-making process, fresh water enters the water
tank continuously as the water from the trough freezes continuously on the evaporator.
