•
Never turn the water supply tap off when the ice maker is working.
•
Never touch the evaporator when the machine 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
When the power switch is first turned ON, the machine is in Stand-by mode. After about 3
minutes, it will automatically proceed to 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, but the water pump has
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.

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.
