Page 22: Operational Cycles
Theory of Operation Model 315I (UC Ice Maker) OPERATIONAL CYCLES There are two operational cycles of the icemaker: • Ice Making (Freeze) Cycle • Harvest Cycle The ice making (freeze) cycle happens when water from the reservoir is sprayed into the ice cube molds at the bot- tom of the evaporator and the water freezes into cubes. -
Page 23: Harvest Cycle
Theory of Operation Model 315I (UC Ice Maker) Harvest Cycle During the harvest cycle the compressor is still operating, but the condenser fan and circulating spray pump are switched off. The hot gas valve opens, interrupting the flow of warm refrigerant from the compressor to the con- denser, diverting it to the evaporator. -
Page 24: What To Expect From The Model 315I
WHAT TO EXPECT FROM THE MODEL 315I The model 315I will release a batch of eight ice cubes approximately every thirty minutes. At the same time the cubes fall into the bin, water will be filling the reservoir and carrying the mineral impurities down the drain. -
