Operation

HOW THE MACHINE MAKES ICE

Press the ON/OFF button in front panel to turn on
the unit, then the LCD screen lights. 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 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

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 floor 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 flow of the refrigerant or the water line. Items stored on top of the ice
cube machine can also make noises
• The high-efficiency 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 cube machine will not be used for a long time, or it is to be moved to another place, it will be
necessary to drain the system of water
1. Shut off the water supply at the main water source
2. Disconnect the water supply line from the water inlet
3. Shut off the power supply at the main electrical power source
4. Screw off the water tank screw nut and drain out water completely, tighten the nut after fnishing. Dry
the tank. Note: Don't forget to screw the nut back into place again.
5. Remove the ice from the ice storage bin. Dry the bin.
6. Leave the door open to allow for circulation and to prevent mold and mildew.
7. Leave the water supply line 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
