ice storage bin.
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 can be Turn On or Off
automatically with the door opening or closing.
7. Pump Water Drain system (If use): as soon as the ice melt water or other
surplus overflow water into the water reservoir reaches the maximum level,
the water lever switch close and transmit a low voltage current to PC board.
The PC board energises the water drain pump for 20 seconds pumping out
most of the water contained into the water reservoir.
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 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.
