ICE Series Start-Up Procedure

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 or 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: 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 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.
Evaporator
Undercounter Models
Turn the machine to the ICE or WASH position. Hold ice against the brass
thermal-well mounted to the water trough making sure the ice is in contact with
at least 6 inches (15 cm) of the thermal-well. The machine should shut off in
approximately 1 minute, remove the ice, the machine should restart in
approximately 3 minutes. If a major adjustment is required, turn the adjustment
screw counterclockwise (warmer) until it stops then turn the adjustment screw
clockwise (colder) 1/8 of a turn. This should put the control close to the proper
adjustment, recheck and make a minor adjustment if needed. If a minor
adjustment is required, turn the adjustment screw clockwise (colder) or
counterclockwise (warmer). Adjustments are not covered under warranty.
