As ice level increases in the ice storage container, the switch assembly is pushed back. When the ice storage container is full, it de-actuates the switch which stops the compressor and the ice making cycle. Publication Number: 630460082SER - 9 - © 2004-2014, Cornelius Inc. -
Page 14: Refrigeration Systems
XPANSION ALVE You will find a thermal expansion valve on Cornelius Ice Makers, which is used to control the amount of refrigerant flowing through the evaporator. Improperly installed or defective expansion valves may cause low production, soft ice, squeaking from evaporator, and excessive load inside the evaporator. -
Page 15: Temperature / Pressure Chart
Refer to TEMPERATURE/PRESSURE CHART. Closing point of valve should be set low enough to close valve during compressor stand by periods. NOTE: Cold water will absorb more heat faster than warm water. The water flow will therefore auto- matically increase as inlet temperature increases. Publication Number: 630460082SER - 11 - © 2004-2014, Cornelius Inc. -
