GEM0650/0956/1256 A/W Operation: Water Page 15 Water enters the machine through the 3/8 inch male flare at the rear of t he cabinet, goes to the water reservoir which it enters through the float valve. The water then goes out the bottom of the reservoir tank to the bottom of the evaporator.
GEM0650/0956/1256 A/W Operation: Performance Page 16 Beginning at the compressor, the refrigerant is compressed into a high temperature gas. The discharge line directs this gas to the condenser. At the condenser ( air or water coole d) the gas is cooled by either air or water and then it condenses into a liquid.
GEM0650/0956/1256 A/W Sanitizing and Cleaning Page 17 It is the USER’S RESPONSIBILITY to keep the ice machine and ice storage bin in a sanitary condition.
