REPLENISHING CO
2
SUPPLY
WARNING: CO
2
displaces oxygen. Strict attention must be observed in the prevention of
CO
2
(carbon dioxide) gas leaks in the entire CO
2
and soft drink system. If a CO
2
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 CO
2
gas will experience
tremors which are followed rapidly by loss of consciousness and suffocation.
NOTE: When indicator on primary CO
2
cylinder regulator assembly 1800-psi gauge is in shaded
(‘‘change CO
2
cylinder’’) portion of the dial, CO
2
cylinder is almost empty and should be changed.
1. Fully close (clockwise) CO
2
cylinder valve.
2. Slowly loosen CO
2
regulator assembly coupling nut allowing CO
2
pressure to escape, then remove regula-
tor assembly from empty CO
2
cylinder.
3. Unfasten safety chain and remove empty CO
2
cylinder.
4. Position full CO
2
cylinder and secure with safety chain.
WARNING: To avoid personal injury and/or property damage, always secure CO
2
cylinder in
upright position with safety chain to prevent it from falling over. Should valve become
accidentally damaged or broken off, CO
2
cylinder can cause serious personal injury.
5. Make sure gasket is in place inside CO
2
regulator coupling nut, then install regulator on CO
2
cylinder.
6. Open (counterclockwise) CO
2
cylinder valve slightly to allow lines to slowly fill with gas, then open valve
fully to back-seat valve. (Back-seating valve prevents leakage around valve shaft).
7. Check CO
2
connections for leaks. Tighten loose connections.
SYRUP FLAVOR CHANGE
One or both syrup flavors can be changed at the same time. Perform flavor change on one system as follows:
1. Perform sanitizing procedure on syrup system. Syrup flavor change will be made as instructed in the
SERVICE AND MAINTENANCE SECTION.
IMPORTANT: The following CO
2
and liquid disconnects disconnecting and connecting procedure for
soft drink tank replacement or filling soft drink tank in place must be performed in order as follows:
2. To disconnect soft drink tank from Unit syrup system.
A. Disconnect liquid disconnect from soft drink tank. NOTE - Disconnecting liquid disconnect from
soft drink tank first prevents syrup from backflowing through Unit syrup flow regulator, which
may alter regulator adjustment.
B. Second, disconnect CO
2
quick disconnect from soft drink tank.
3. To connect soft drink tank into Unit syrup system.
A. First, connect CO
2
quick disconnect to soft drink tank to pressurize tank.
B. Second, connect liquid quick disconnect to soft drink tank.
4. First, pressurize soft drink tank containing new flavor syrup by connecting CO
2
line to tank, then connect
Unit syrup inlet line to tank.
