Connecting the Regulator to the CO2 Cylinder
1. Remove blue plug from regulator fitting.
(Note: Do not remove the carbonic washer.)
2. Screw regulator onto gas cylinder valve. Tighten
with wrench until vertically straight. Be sure that
shut-off valve (black lever) on regulator is in
OFF (horizontal) position.
3. Place a screw clamp over end of red air line and push
onto regulator tailpiece. Tighten clamp with a screwdriver.
Adjusting CO2 Gas Flow
1. Turn regulator adjusting screw counterclockwise until it turns freely.
2. Turn hand valve counterclockwise on CO2 cylinder
to the fully open position.
3. Turn regulator adjusting screw clockwise until desired
pressure is reached (approx. 12-15 lbs.). Tighten stop nut on adjusting screw.
4. Open shut-off valve on bottom of regulator.
CO2 Leak Test
Dilute a small amount of liquid dishwashing soap and rub the soapy
mixture around each connection. If bubbles appear, tighten connection.
Replacing CO2 Gas Cylinder
1. Turn the CO2 hand valve clockwise until seated and close shut-off valve on regulator.
2. Unscrew regulator from cylinder fitting.
3. Replace carbonic washer (Part No. 157F2P), if needed and reattach regulator to filled cylinder.
4. Turn CO2 hand valve counterclockwise until fully open. Turn regulator shut-off valve
to open position.
5. Adjust CO2 gas flow as required, turning clockwise for higher pressure.
Proper CO2 Handling
Always...
• Connect a regulator (reducing valve) to a CO2 cylinder.
• Secure cylinder in upright position whether in storage or in use.
• Keep cylinder away from heat. Rupture disc vents at 122
o
F. maximum.
• Ventilate room after high pressure gas leakage.
• Check the last DOT test date on cylinder neck before filling. If more than five years old,
the cylinder must be retested to DOT specifications.
• Be sure CO2 cylinder outlet fitting is free of dust or dirt before attaching regulator.
• Store CO2 cylinder and regulator assembly upright.
• Allow only properly trained and experienced personnel to handle high pressure gas.
Never...
• Connect cylinder directly to a keg without a regulator (reducing valve).
• Drop or throw regulator or CO2 cylinder.
• Transport CO2 cylinder in a closed vehicle.
• Apply oil to a regulator.
• Shut off CO2 cylinder when not in use. You will not save gas by doing so!
• Allow untrained, inexperienced personnel to handle high pressure gas.
Failure to heed this warning could result in personal injury or death.
