Normal Operation
When the toggle switch is placed in the ON position the
following controls must be in the closed position before
the ice machine will start:
A. Bin Thermostat
B. High Pressure Cut-out Switch
C. Ice Chute Safety Switch
D. Low Pressure Switch
E. Low Water Level Switch
NOTE: Placing the toggle switch in the ON position starts
the gear motor. After the rotation speed sensor verifies
10 minutes of correct rotation the time delay ends and
the compressor starts. The ice machine will continue to
make ice until ice contacts the bin thermostat. The ice
machine remains off until ice no longer contacts the bin
thermostat.
