Ice Making Sequence of Operation

NOTE: The On/Off button must be depressed and the ice damper must be closed before the ice machine will start.

Water Purge Cycle

The ice machine purges any remaining water from the

Harvest Cycle

Any remaining water is purg refrigerant gas warms the evaporator. When the evaporator warms, the sheet of cubes slides off the evaporator and into the storage bin. If all cubes fall clear of the ice damper the ice machine starts another freeze cycle.

SAFETY LIMITS

Safety limits are stored and indicated by the control board. T machine varies for each safety limit.

Safety limits can be reset by pressing the and starting a new ice making cycle.

A safety limit is indicated by an energized Service Light on the safety limit indication.
