Use this article when a keg is empty and needs to be replaced.
Important
Tap systems operate under pressure.
Never disconnect a coupling while the system is still pressurized.
Steps: disconnecting the empty keg
1. Close the tap
Make sure no beer is still flowing.
2. Close the CO2
Turn off the CO2 bottle.
3. Release the pressure
Briefly pull the pressure relief valve
Or dispense a small amount of beer
→ You will often hear a short hiss
4. Unlock the coupling
Push the handle slightly down
Then pull it up into the vertical position
5. Remove the coupling
Turn it a quarter turn counterclockwise and lift it up.
Connecting a new keg
Place the new keg in a stable position
Check that the correct keg has been selected
Place the coupling straight onto the keg
Lock it according to the coupling type
Slowly open the CO2
Dispense a test glass to remove air from the line
Check for leaks
Common mistakes
Disconnecting the coupling while the system is still pressurized
Not checking the worn rubber seal
Not dispensing a test glass → air remains in the line
Quick check
Does beer flow without sputtering?
Is there no visible leakage?
Is the CO2 pressure stable?
→ Then everything is connected correctly.
