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. SCR refrigeration is pre-set at factory and ready to operate.
2. Remove lid.
3. Fill water bath with clean water until water runs out of drain standpipe, (S-657).
4. Open water inlet supply line.
5. Plug SCR 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 65 to 75 psi.
Carbonated units only.
3. Dispense water from dispensing valves until the carbonator activates. Carbonated
units only.
4. Allow carbonator to run until it automatically shuts off. Pump is fully primed and
carbonator is now ready for use. Carbonated units only.
5. Check all connections on high pressure C02 system for leaks. Repair any leaks that
are found.
