Operation
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 ows 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 start.
Harvest: During the harvest cycle, the compressor is still operating and power is supplied to the hot gas
valve. Every 20 cycles, the water purge valve opens and allows the water pump to purge the water from
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. When the hot gas valve opens, it allows
hot gas to go directly to 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 xed charge of water that is contained in the water tank. As the water ows 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.
NORMAL SOUNDS
Your new ice cube machine may make sounds that are unfamiliar to you. Most of the new sounds are
normal. Hard surfaces like the oor and walls can amplify the sounds. The following describes the kinds of
sounds that might be new to you and what may be causing them.
• Rattling noises may come from the ow of the refrigerant or the water line. Items stored on top of the ice
cube machine can also make noises.
• The high-efciency compressor may make a pulsating or high-pitched sound.
• Running water may make a splashing sound.
• You may hear air being forced over the condenser by the condenser fan.
• During the Harvest cycle, you may hear the sound of ice cubes falling into the ice storage bin.
PREPARING THE ICE CUBE MACHINE FOR LONG STORAGE
If the ice maker will not be used for a long time, or it is to be moved to another place, it will be necessary
to drain water from the system.
1. Shut off the water supply at the main water source.
2. Disconnect the water supply pipe from the water inlet.
3
. Depress the clean button and hold over six seconds, the machine will go into the draining mode
automatically, with harvest and ice-making indicators blinking, till the water ush down the drain completely.
then the harvest indicator and ice-making indicator LEDs will be on. And the drain process complete.
4. Shut off the power supply at the main electrical power source.
5. Dry the water tank.
6. Remove all ice cubes from the ice storage bin and dry it.
7. Keep the door opening to allow for ventilation and to prevent mold and mildew.
8. Leave the water supply pipe and power cord disconnected until ready to reuse.
IMPORTANT:
• Do not touch the power plug when your hands are wet.
• Never unplug the unit by pulling on the cord.
