Sub-Zero ice machines are factory-operated and adjusted before shipment. Normally, new installations do not require any adjustment.
S U B - Z E R O I C E M AC H I N E O P E R A T I O N O P E R AT I O N A L C H E C K S TESTING AND ADJUSTING THE B I N T H E R M O S TAT The bin thermostat stops the ice machine when the bin is full. It is preset for normal ambient temperatures and adjustments are usually not required. The thermostat is functioning correctly if, when three ice cubes are placed on the thermostat tube for 5 minutes, the ice machine stops. The ice machine should restart 5 minutes after the cubes are removed.
S U B - Z E R O I C E M AC H I N E O P E R AT I O N O P E R AT I O N A L C H E C K S CUBE WEIGHT ADJUSTMENT Adjusting finishing time: The cube weight can be increased from the factory setting by adjusting the finish time. Adjust in 1 minute increments and allow the ice machine to run several freeze/harvest cycles, then inspect the ice cubes. If a heavier cube weight is desired add another minute of freeze time and repeat the process.
S U B - Z E R O I C E M AC H I N E C A R E CLEANING You are responsible for maintaining the ice machine in accordance with the instructions in this manual.
