System Troubleshooting

Direct Draw System

(A direct draw system very short run from keg to tap - no glycol chiller)

Beer Foaming?

1. Temperature in cooler is too warm or cold. Temp. should be between 36-38 degrees.

2. CO2 pressure is too high or low. Pressure on a direct-draw system should be 12-14 PSI. Pouring 2 ounces of beer per second is the recommended flow rate.

3. Keg was just moved into cooler and needs to settle.

No Beer at the Faucet?

Long Draw System

(A long draw system runs long from keg to tap using a glycol chiller)

Beer Foaming?

1. Temperature in cooler is too warm or cold. Temp. should be between 36-38 degrees. Check the temperature of a liquid in the cooler to get an accurate reading. Gauges on a cooler can often be inaccurate.

a. If the temperature in the cooler is between 36-38 degrees, check the temperature of the beer coming out of the faucet. It should be between 36-38 degrees. If there’s a more than a 4-6 degree difference between temperature at the faucet and cooler the problem is at the glycol unit. Contact Pure Tap to help diagnose your glycol issue.

2. CO2 pressure is too high or low. Pressure on a long draw system can vary. Contact Pure Tap to help determine your proper pouring pressure.

No Beer at the Faucet?

1. Check to see if CO2 or Nitrogen tank are empty. If one of these tanks are empty your blend box will stop the flow of pressure to the rest of the beer system.

2. One of your gas regulator shutoffs are closed. Check regulator at the CO2 and Nitrogen cylinders, and the regulators inside the cooler.

3. Keg is empty or not properly tapped

4. FOB (Foam on Beer Detector) is not properly reset.

Changing Co2 Cylinders

How to Remove a Regulator

1. Shut off valve A on the bottom of the regulator.

2. Turn cylinder valve off by turning cylinder valve "B" clockwise until it is snugged.

3. Completely unscrew regulator adjustment screw "C" counter-clockwise.

4. Unscrew the regulator stem nut "D" from the cylinder and place the regulator in a safe place.

5. Undo the cylinder safety chain, replace the empty cylinder with a full one, and re-secure with the safety chain.

How to Install a Regulator

1. Check the condition of the stem quad ring and install regulator by screwing regulator nut "D" onto cylinder valve (snug nut with wrench).

2. Open cylinder valve "B" completely.

3. Screw regulator adjustment screw "C" until desired pressure is reached

4. Open the shut off valve "A" to start the supply of CO₂ to the kegs.

Important Facts

Make certain that these instructions are read and understood by anyone using a CO₂ regulator!

1. Always use a CO₂ regulator in a CO₂ system, failure to do so can cause injury or even death.

2. CO2 is pressurized to 875 PSI at 70degrees and can be hazardous.

3. If the DOT test date on the top of the cylinder is older than five years, do not use the cylinder.

4. Beer dispensing is done at 10-18 PSI.

5. Dispensing beer through a cold plate is done at 30-35 PSI.

6. Keep cylinder away from heat.

Proper Handling of a CO₂ Cylinder

1. Do not drop or throw a CO₂ cylinder.

2. Use a chain to secure your cylinders in an upright position.

3. Store unused cylinders at approximately 70 degrees Fahrenheit.

4. If a CO2 leak is found, ventilate and leave the area.

5. Do not hook up a CO2 system unless there are at least two safeties between the cylinder and the keg.

6. Do not exceed 35 PSI.
