ICE Series
Bin Control Operation
The bin control is used to shut the machine off when the bin fills with ice. The bin control must be checked upon
installation or initial start-up and when performing maintenance. Adjustments are not covered under warranty.
There is one bin switch for each evaporator. The actuator arm of the bin switch comes in contact with the splash
curtain. When the bin is full of ice, the splash curtain is held open when ice drops off of the evaporator. This releases
the pressure of the bin switch actuator arm allowing the switch to open.
Single evaporator machines: (Including the ICE1506R) If the bin switch opens during freeze or the first part of
harvest, relay 2 bypasses the bin switch and the machine will continue running. If the bin switch is opened during
harvest when the cam switch is lifted onto the high part of the cam, the machine will shut off. When the bin switch
closes again, the machine will restart.
Dual evaporator machines: If either bin switch opens during the freeze cycle, the machine will shut off. Relay 1 and
relay 2 will bypass the bin switches during defrost. If either bin switch is open when the machine returns to the freeze
cycle, the machine will shut off.
Undercounter machines: A thermostatic bin control is used on the undercounter
models. The bin thermostat is located in the control box with a capillary tube,
which is in a brass thermo-well mounted to the right side of the water trough.
When ice comes in contact with the capillary tube thermo-well, the bin thermostat
opens and the machine will shut off.
Bin Control Adjustment
All Models (Except Undercounter Models): Check the bin switch for proper
adjustment by swinging the bottom of the curtain away from the evaporator.
Slowly bring the curtain towards the evaporator. The switch should close when
the bottom edge of the curtain is even with the outer edge of the water trough.
Adjust the switch by loosening the nuts that hold the switch in place. Move the
switch to the proper position and retighten the nuts. Recheck the adjustment.
Adjustments are not covered under warranty.
Undercounter Models and ICE1506R
The Bin Thermostat used on these Self Contained Ice Cuber Machines is a
sensitive device influenced by ambient conditions including altitude and
temperature. The machine is set up to operate properly at the factory for 70°F at
sea level. If your ice machine shuts off early, bin half full, or doesn't shut off, bin
overflowing, please follow these instructions to set the bin thermostat.
1. These instructions are best followed on a full ice bin with at least 3 inches
of ice resting against the brass thermal well. The machine must be
running to perform this adjustment; follow step two if the machine is off.
2. Turn the thermostat adjustment screw clockwise until it stops; this is the
max cold setting and will prevent the machine from shutting off.
3. Hold a minimum of 3 inches of ice against the middle of the brass thermal
well for 3-4 minutes. It is imperative that enough ice be used for the

prescribed time to properly cool the
thermostat.
4. Slowly turn the adjustment screw counter-
clockwise until the machine shuts off. If
the screw is turned too quickly, the
thermostat could be set to too warm a
temperature. Turn slowly.
5. Remove the ice from the well and warm
the brass with your hand; the machine
should turn back on.
The ice machine is now set for ambient
conditions. If the ice machine location
experiences significant changes in ambient
temperatures, this procedure will need to be
followed again. Adjustments are not covered
under warranty.
