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 is controlled by a magnetic reed switch that has
been installed on the inner surface of the door. It is turned On or Off automatically
with the opening or closing of the door.
7.
Pump Water Drain system (if used): As soon as the ice melt water or other surplus
overflow water in the water reservoir reaches the maximum level, the water level
switch closes and transmits a low-voltage current to the PC board. The PC board
energizes the water drain pump for 20 seconds, pumping out most of the excess water
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.
