CHAPTER III

PREPARATION

All steps in previous chapters should be understood and carried out before proceeding.

PREPARING SYSTEM FOR OPERATION

Be sure that electrical power is unplugged, valve on C02 cylinder is closed, and valve on water

supply line is closed, and release pressure of C02 gas and water from carbonator tank.

PREPARING AND STARTING REFRIGERATION UNIT

1. CR-UC# refrigeration is pre-set at factory and ready to operate.

2. Remove lid.

3. Fill water bath with clean water up to ¼” from top of standpipe or until water runs out

of drain standpipe, (S-657). (water will drain from standpipe until ice bank is completely

made)

4. Open water inlet supply line.

5. Plug CR-2 or CR-UC2 power cord into electrical receptacle box. Make sure

compressor, condenser fan motor, agitator motor start. The process of cooling the water

bath will now commence. With ambient and water temperature of 75 degree “F” initial

pull down or formation of complete ice bank will take approximately 5 hrs. When full ice

bank has been formed, compressor and condenser fan motor will stop. Agitator will

continue to operate, circulating water in water bath.

ACTIVATE HIGH PRESSURE C02 SYSTEM

1. Open valve on the C02 cylinder. Be sure to open valve completely or until valve is

back seated.

2. Turn high pressure C02 regulator screw clockwise until the pressure is 55 to 75 psi.

3. Dispense water from dispensing valves until the carbonator activates.

4. Allow carbonator to run until it automatically shuts off. Pump is fully primed and

carbonator is now ready for use.

5. Check all connections on high pressure C02 system for leaks. Repair any leaks that

are found.

ADJUST WATER FLOW RATE

Control dispensing water flow rate at the faucets by adjusting the flow compensator valve

handle on the right side of the black faucets. Horizontal is full open. Quarter turn is closed.

Incoming water pressure from the water filter to the CR unit can be set via the Water Pressure

Regulator. Set between 40 and 60 psi. Or use the preset nonadjustable 50 psi regulator.
