SELF-CONTAINED AIR-COOLED
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. Ice Chute Safety Switch
C. Low Water Level Switch
D. High Pressure Cut-out Switch
E. Low Pressure Cut-Out Switch
Placing the toggle switch in the ON position starts the
gear motor and an 8 minute compressor time delay. The
compressor starts and the float valve controls the water
inlet valve and water level. The freeze cycle ends when ice
contacts the bin thermostat. The ice machine remains off
until ice no longer contacts the bin thermostat.
