Indicator Lights:
• Bin Full: On when bin is full, goes on and
off as ice falls during a harvest cycle.
• Freeze: On when the unit is in the Freeze
cycle, blinks when a freeze mode is pending.
• Harvest: On when the unit is in the Harvest

a problem with the water system.
• Refrigeration: On when the controller has

Cycle Definitions:
• Freeze: The refrigeration system is
operating to remove heat from the
evaporators. The compressor, fan motor (if
air cooled) and water pump are ON.
• Harvest: The refrigeration and water
systems are operating to harvest the ice
cubes. While the compressor is on for the
full cycle, the water pump will be off at the
beginning and inlet water valve will switch off
before the end.
• Clean: The Inlet Water Valve opens to fill the
reservoir. The Water Pump starts. The Clean
indicator light is switched ON. A manually
initiated rinse flushes the system.
