Freeze Cycle Operation

During the Freeze cycle, the water inlet valve

energizes and de-energizes in conjunction with the

water level probe located in the water trough.

During the first 45 seconds of the Freeze cycle:

• The water inlet valve is ON when there is no water

in contact with the water level probes.

• The water inlet valve turns OFF after water

contacts the water level probes for 3 continuous

seconds.

• The water inlet valve will cycle ON and OFF once

in the prechill and up to two times in the freeze

cycle.

• Maximum fill time is 6 minutes for single

evaporator.

After 45 seconds into the Freeze cycle:

The water inlet valve will cycle ON, and then OFF one

more time to refill the water trough. The water inlet

valve is now OFF for the duration of the freeze cycle.
