compressed into a high temperature gas. The discharge line directs this gas to the condenser. At the condenser (air or water cooled) the gas is cooled by either air or water and it then condenses into a liquid. This high pressure liquid then goes through the liquid line to the expansion valve. The thermostatic expansion valve meters liquid refrigerant into the evaporator, the volume of liquid refrigerant depending upon the temperature of the evaporator; warmer evaporators get more refrigerant and colder evaporators get ...

CONFORM TO ALL APPLICABLE CODES Water Inlet Air Cooled Models: The recommended water supply is clean, cold water. Use 3/8" O.D. copper tubing, connect to the 3/8" male flare at the back of the cabinet. Install a hand valve near the machine to control the water supply. Water Treatment: In most areas, a water filter of some type will be useful. In areas where the water is highly concentrated with minerals the water should be tested by a water treatment specialist, and the recommendations of the specialist regarding filtration and/or treatment should be followed. Water Cooled M ...

(Assuming all steps to remove the auger have been performed.) 1. The gear motor/evaporator assembly will have to be exposed. 2. Remove the 4 hex head cap screws holding the evaporator to the gear motor assembly. Lift the evaporator up and off of the gear motor. 3. Remove the snap ring or wire retainer from the grove under the water seal. 4. Pull or drive out the lower half of the water seal. To Replace the Water Seal: 1. Lubricate the water seal with water, and push the water seal into the bottom of the evaporator slightly past the grove for the snap ring. 2. Replace ...

If the machine is switched off at the master switch, but is otherwise ready to go, switching the master switch to on does the following: ••The bin empty light on the circuit board goes on ••There is a 15 second delay ••If there is enough water in the reservoir, the circuit board will allow the machine to start up. Start up consists of: ••The compressor relay and auger motor relay become energized, connecting power to the windings of the auger motor. ••The auger motor starts, and the centrifugal switch closes, connecti ...
