CME1356R and CME1656R
Component Location and Function
Reservoir: Contains the water used to make ice.
Water Inlet Valve: Opens to allow water into the reservoir.
Evaporators/Freezing Compartment: Location of the evaporators. Ice forms on the evaporators, and is released when warmed up during the harvest cycle. The freezing compartment is fully insulated for maximum efficiency.
Cube Deflectors: The slots in the inclined deflectors let the water falling from the evaporators back into the reservoir, but when ice falls during harvest, the ice slides off into the bin.
Harvest Bypass Valve: Injects additional refrigerant into the harvest system.
Water Pump: Forces the water from the reservoir to the top of the evaporator(s). The motor is kept separate from the water to minimize contact with moisture.
Head Pressure Control Valve
Hot Gas Valve: Closed during freeze, it opens during harvest to divert hot discharge refrigerant gas into the inlet of the evaporators.
Purge Valve: Opens during the first part of harvest, when the water pump restarts the water in the reservoir is diverted to the drain.
Check Valves: Liquid and Discharge lines contain check valves. These control refrigerant migration during the Harvest and Off cycles.
