Sanitise the Filling Coupler & Keg Head

Spray the head of the keg and the filling coupler thoroughly with a food-safe disinfectant. We recommend using ethanol.

Prime the Beverage Line

Open the liquid ball valve on the coupler to prime the beverage lines, completely purging them of all air and residual sanitiser.

Ensure the ball valves on the coupler assembly are closed, then slide the coupler onto the keg head. Push down the handle/lever to fully engage the keg.

Place the keg upside down on your filling table and open the liquid-side ball valve. (Note: Liquid may not begin to flow yet due to the internal counter-pressure of the keg).

Gradually release the internal pressure by opening the gas-side ball valve. Maintain a counter-pressure level strictly above the equilibrium pressure of the beverage to ensure CO₂ doesn't break out of solution.

• Recommendation: 0.5–1.0 bar is the minimum recommended pressure release setting for carbonated beverages to prevent foaming. Once the keg is filled, wait 5 seconds and close the valve.

Close both ball valves on the coupler assembly, disengage the filling coupler from the keg, and immediately clean head with warm water, and spray the keg head again with disinfectant (ethanol).

Flip the keg back to its upright position and firmly click the included anti-tamper cap onto the keg head.

To guarantee that the keg is filled to its exact specification, cross-reference the volume using a calibrated digital scale.

• Determine the exact target weight of a full 20L keg by accounting for both the specific gravity (density) of your beverage and the tare weight of the empty keg assembly.
