Flake Ice Machines
Safety Control
The low temperature safety control prevents the machine from
operating without water in the evaporator of if the v-belt breaks. If
the evaporator temperature drops below approximately 30°F (-1°C),
the safety control will open and shut the machine off.
The safety control is located in the control box and the capillary
tube is located in a thermal well attached to the bottom of the evaporator barrel just above the
lower nut.
To check the safety control for proper operation, turn the water supply to the float off and
allow the machine to operate. When the water in the float and feed tube has been depleted,
the safety control should open, shutting the machine off within approximately 3 minutes.
Once the water supply has been turned back on, the control should close and the machine
should start within approximately 5 minutes.
The safety control can be adjusted by turning the adjusting screw clockwise to lower the cut-
out temperature (colder) and counterclockwise to raise the cut-out temperature (warmer).
Bin Control
A primary thermostatic bin control and mechanical secondary bin switch in used to shut the
machine off when the bin becomes full of ice.
Thermostatic Bin Control
The thermostatic bin control is located in the control box with the
capillary tube housed in a thermal well located in the bin or down chute.
When ice comes in contact with the thermal well, the contacts in the
control open and the machine shuts down.
When ice is removed, the machine comes back on. Check the thermostatic bin control for
proper adjustment with the machine running by covering approximately 6 inches (15CM) of
the thermal well. The machine should shut off in approximately 3 minutes. Remove the ice
once the machine shuts off and the machine should restart within approximately 5 minutes.
The bin control can be adjusted by turning the adjusting screw clockwise to lower the cut-out
temperature (colder) and counterclockwise to raise the cut-out temperature (warmer).
