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.

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 CCM1530) 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	Bin Switch
	Adjustment
models. The bin thermostat is located in the control box with a capillary tube,	Nuts
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.

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).

Splash Curtain

Evaporator

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