Replacing Carbon Dioxide

1. Twist the main cylinder valve knob, located on top of the carbon dioxide cylinder, clockwise to shut it.

2. Adjust the secondary shut-off valve, which looks like a lever and is located on the lower portion of the keg cooler's pressure indicator/valve assembly, to a horizontal position.

3. Pull the clamp from the air line and take the hose out of the regulator.

4. Pull the regulator assembly, which connects the carbon dioxide cylinder to the keg cooler, off of the cylinder.

5. Take the cap off of the new carbon dioxide cylinder.

6. Place the new carbon dioxide cylinder in the old one's position and twist the regulator assembly to attach the new cylinder to the keg cooler.

7. Replace the air line clamp and hose, removed from the old cylinder, on the new one.

8. Slowly twist the valve on top of the carbon dioxide cylinder counterclockwise to open it. Watch the regulator pressure indicator, which is the upper indicator display, to be sure the pressure remains between 10 and 12 lbs. per square inch.

9. Turn the secondary shut-off valve back to a vertical position to open it.

Tapping a Keg

1. Verify that the beer faucet is turned off.

2. Take the cover off of the keg and look at its handle. It should be straight up, in the "off" position.

3. Push the keg coupler into the beer keg's neck. Twist it clockwise to lock it.

4. Adjust the keg coupler handle. Pull it toward you and push down until it locks.

Drawing the Beverage

1. Turn on your sink's cold water faucet, and run water over the beer mug.

2. Hold the mug under the keg's tap, with the base of the mug at a 45-degree angle to the tap assembly. The mug should be about 1/4 inch away from the spout.

3. Pull the handle toward you fully until the mug is filled two-thirds with beer.

4. Reposition the mug to a level position while allowing beer to pour into its center until it is full.

5. Push the handle back to the upright position.
