4. When the ice storage bin is full, the sheet of cubes will not fall completely and
will hold the bin-full probe open. The machine stops making ice automatically.
5. The unit will start making ice again after the ice cubes are removed. Then the
bin-full probe swings back to operating position.
6. Bin light (if present): The bin light will be controlled by magnetic reed switch that
has been installed in the inner of the door. It will be turned On or Off
automatically with the door opening or closing.
IMPORTANT:
• Although the unit has been tested and cleaned at the factory, due to long-term
transit and storage, the first 3 batches of cubes must be discarded.
• Never turn the water supply tap off when the ice maker is working.
• Never touch the evaporator when unit 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
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.
