Operation
Ice Making Sequence of Operation
NOTE: The toggle switch must be in the ON position
and the water curtain must be closed before the ice
machine will start.
Water Purge Cycle
The ice machine purges any remaining water from the
water trough down the drain.
Freeze Cycle
Prechill - The refrigeration system chills the evaporator
before water flow over the evaporator starts. The
water inlet valve energizes during the pre-chill and
remains on until the ice thickness float switch is
satisfied.
Freeze - Water flowing across the evaporator freezes
and builds ice on the evaporator. After a sheet of ice
has formed, the Harvest float switch signals the control
board to start a harvest cycle.
Harvest Cycle
Any remaining water is purged down the drain as
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 water curtain, the ice machine starts
another freeze cycle.
Full Bin Cycle
If the water curtain is held open by ice cubes the ice
machine shuts off. When the water curtain closes the
ice machine starts a new cycle at the water purge.
