Component Location
The ice machine is designed for front service.
Many components are serviceable from the front
without removing the cabinet. With the cabinet
removed, nearly all components are serviceable.
In the bin area can be found
••
Float
••
Reservoir
••
Evaporator
••
Bin Thermostat sensing tube
Behind the right front grill on the front edge of the
control box:
••
Bin thermostat
••
Master switch
Inside the control box are the auger delay control,
low pressure cut out, and the contactor.
Auger Delay Pressure Control: This pressure
switch, connected to the low side of the
refrigeration system, controls the auger drive
motor.
Low Pressure Control: This pressure switch,
connected to the low side of the refrigeration
system, is normally closed when the machine is
operating. If the low side pressure should drop too
low, the control will open (at 0-4 PSIG), stopping
the ice maker. It is an automatic reset.
High Pressure Control: The pressure switch is
designed to open and shut off the machine should
the high side refrigeration pressure become too
high, usually as a result of not enough water
through the water cooled condenser.
It is a manual reset.
On-Off switch: This toggle switch shuts off the
machine. It is not a complete disconnect.
Bin Thermostat: This thermostat turns the
machine on and off in response to changes in
temperature of the capillary tube. At the minimum
setting, it opens at 35
0
F. and closes at 45
0
F. At
the maximum setting, it opens at 51
o
F. and closes
at 61
o
F. See "Initial Start Up" for adjustment
information.
