Operation
NOTE: Flake and nugget ice machines use an auger to
remove ice from the evaporator. Occasional noises (creaks,
groans, squeaks, or pops) are a normal part of the ice making
process.
Bin Thermostat and Evaporator Low Temperature
Safety Adjustment Chart
The bin thermostat sensing bulb is located in the ice chute
or bin and turns the ice machine on and off as the level
of ice in the ice chute or bin changes. The evaporator low
temperature safety protects the evaporator and compressor
from damage caused by water loss or gear motor failure.
