The potentiometer is used to adjust the defrost time and it is set directly from the factory according to 
the model of the ice machine. It can be adjustable from a minimum defrost time of 60" (turn clockwise), 
to a maximum of 180" (turn counterclockwise). 

MASTER SWITCH

 

(only UCG45/65/85/105

 Switch Position 1

Fitted in the control box the master switch has to be used to start‐up and to stop the ice maker 
operation. 

COMPRESSOR SWITCH 

(only UCG135/165) 

Located in the control box is used to de‐energized the compressor during the cleaning. 

FAN PRESSURE CONTROL (only UCG135‐135) 

Used on air cooled ice makers to maintain the head pressure within the preset values. 

WATER REGULATING VALVE (only UCG165Water cooled version only) 

This valve controls the head pressure in the refrigerant system by regulating the flow of water going to 
the condenser. As pressure increases, the water regulating val‐ ve opens to increase the flow of cooling 
water.
