and Restart

Shutdown Delay:

•Fill Cycle – 15 sec. after activation.

•Harvest Cycle – At the end of the harvest cycle, or up to 15 sec. into the freeze cycle if activated at the end of the harvest cycle.

•Freeze Cycle – 15 sec. after activation if activated at least 15 sec. before the 5-min. short cycle protection timer terminates. Otherwise, at the end of the next harvest cycle.

Components Energized when the Control Switch is in the "SERVICE" Position

When in the "SERVICE" position, the control switch supplies power to the service switch and the icemaker is in service mode. The service switch has three positions: "DRAIN," "CIRC." and "WASH." See the information below for details of each function.

DRAIN

Power is supplied to the pump and drain valve. This drains the water tank.

 

 

CIRC.

Power is supplied to the pump only. This operation can be used to circulate cleaner and

 

sanitizer over the outside surface of the evaporator for extended periods of time.

 

 

WASH

Power is supplied to the pump and wash valve. This operation is used to circulate cleaner

 

and sanitizer over both the inside and outside surfaces of the evaporator.
