INSTALLING PRIMARY CO2 REGULATOR ASSEMBLY ON CO2 CYLINDER

(see Figure 2)

WARNING: To avoid personal injury and/or property damage, always secure CO2 cylinder in upright position with a safety chain to prevent it from falling over. Should the valve become accidentally damaged or broken off, CO2 cylinder can cause serious

personal injury.

WARNING: CO2 displaces oxygen. Strict attention must be observed in the prevention of CO2 (carbon dioxide) gas leaks in the entire CO2 and soft drink system. If a CO2 gas leak is suspected, particularly in a small area, immediately ventilate the contaminated area before

attempting to repair the leak. Personnel exposed to high concentration of CO2 gas will experience tremors which are followed rapidly by loss of consciousness and suffocation.

1.Unscrew protector cap (with chain attached) from CO2 cylinder valve. Open CO2 cylinder valve slightly counterclockwise to blow any dirt or dust from outlet fitting before installing primary CO2 regulator, then close valve.

2.Remove shipping plug from primary CO2 regulator assembly coupling nut and make sure gasket is in place inside nut. Install regulator assembly on CO2 cylinder so gages can be easily read, then tighten coupling nut. DO NOT OPEN CO2 CYLINDER VALVE AT THIS TIME.

CONNECTING SOFT DRINK TANKS CO2 LINES TO PRIMARY CO2 REGULATOR ASSEMBLY

(see Figure 2)

1.Connect soft drink tanks CO2 lines to primary CO2 regulator manifold assembly as shown in Figure 2.

2.Install gas quick disconnects on ends of soft drink tanks CO2 lines. DO NOT CONNECT CO2 LINES TO TANKS AT THIS TIME.

PREPARING UNIT SYRUP INLET LINES FOR CONNECTION TO SOFT DRINK TANKS

(see Figure 2)

1.Route Unit syrup inlet lines labeled No. 1 and No. 2 to soft drink tanks location.

2.Install liquid quick disconnects on ends of Unit syrup inlet lines. DO NOT CONNECT SYRUP LINES TO SOFT DRINK TANKS AT THIS TIME.

CONNECTING CO2 SOURCE LINE TO UNIT CO2 INLET LINE
