EdgeStar Full Size Ice Maker 8

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 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

Turn the power switch to the ON position. The machine will automatically

start the ice making stage. There are two distinct cycles: freeze and

harvest. During the freeze cycle, water is sprayed against 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

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 have been

harvested.

How the machine uses the water

The ice maker begins with a fixed charge of water that is contained in the

water sump. As the water is sprayed against the freezing evaporator

surface, the portion of water that does not contain mineral impurities will

freeze and stick to the ice cube molds. The water containing impurities

falls back into the water sump. Gradually, during the freezing portion of

the ice-making cycle, the water in the sump will become highly

concentrated with mineral impurities. During the harvest cycle, fresh

water flows into the machine to dilute the bin water and rinse the

concentrated minerals down the drain.
