Bin Control Operation

ICE Series

Start-Up Procedure

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.	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.

Splash Curtain

Adjustment Nuts

The bin switch contacts must be closed when the bottom edge of the curtain is flush with the edge of the water trough
