1. Place a NEW fiber washer or nylon washer inside the coupling nut of the regulator and screw the nut to the cylinder valve outlet. Tighten with a wrench. Make sure that it is really tight. This is the spot where most air leaks occur. The new washer will compress to about half of its original size and fill any gaps or spaces. If not tight enough, this connection will leak at some point. Do not use old or scored washers. Some regulators may have a built-in “O” ring in the regulator stem. In these cases, a CO2 fiber washer is not necessary, but as the ring wears, a new ring or CO2 washer will be needed.
2. Turn the shut-off valve at the base of the regulator to the “OFF” position (to the left or right).
3. Open the drum cylinder valve all the way out (that’s the big screw on the face of the regulator). This is important because the cylinder valve seats in two places.
4. Turn adjusting screw clockwise until correct pressure is indicated on gauge (approx. 10-12 psi).
5. Attach keg coupler to keg. Open the valve on your CO2 tank all the way open. Pressurize keg by placing the handle of the shut-off valve on the regulator in the “OPEN” position (straight up and down).
How to store your CO2 tank and other pressure troublehooting tips
1. Store a CO2 tank upright, NEVER on its side. A full CO2 tank at room temperature will read approximately 700-800 lbs. PSI. At 40º F. it will read approximately 600 lbs. psi.
2. Turn gas pressure ON immediately after connecting the keg coupler to the keg. Do not run system off keg pressure alone as this will use up the natural carbonation, making the beer flat and possibly causing a back flow of beer to the regulator. Turn gas OFF when changing kegs, cleaning hoses or as soon as the keg is empty.
3. Be careful with the regulator, as the gauges on it are somewhat delicate and can easy break. Keep the CO2 tank chained to a wall to prevent it from tipping over.
4. Never allow draft beer to warm up. Keep the beer refrigerated. Draft beer is at its delicious best when served at 36º to 40º F. If the temperature is too cold, the beer will absorb too much CO2 and overcarbonate. If the temperature is too warm, the beer will become foamy and go into secondary fermentation. Use a thermometer to assure that proper temperature is maintained.
5. When drawing beer, always pull the faucet fully open, NEVER half way.
How to read the high pressure gauge (0-3000) on a Double Gauge CO2 Regulator with a 5lb CO2 tank
On the CO2 regulator with a 5lb Tank there are two different readings:
- IF YOU HAVE THE TANK IN THE FRIDGE THE 0-3000 GAUGE WILL READ 500 – 600PSI WHEN THE TANK IS FULL.
- IF YOU HAVE THE TANK OUTSIDE THE FRIDGE THE 0-3000 GAUGE WILL READ 700 – 800PSI WHEN THE TANK IS FULL.
- WHEN THE TANK IS EMPTY IT WILL SHOW 100PSI.
- ALSO, WHEN THE AIR TANK IS INSIDE THE FRIDGE YOU WILL LOSE ABOUT 5 PERCENT OF THE CO2.
- TAKE INTO CONSIDERATION THAT YOUR AIR TANK MAY BE ALMOST EMPTY DUE TO EITHER AN AIR LEAK OR THE TANK NOT BEING FILLED COMPLETELY.
