Installation and setup guide
Depending on the type of Tower, drill appropriate holes (~Ø60mm) through the top of the Keg
Cooler and install the Towers.
Mount the gas regulator, the dNim Module and the gas bottle holder bracket to the side walls
inside the Keg Cooler, a suggested layout is shown on the image to the right.
Install a mixer disc between the shank and the tap, se image 1

Gas lines:
Connect one gas line to the Keg coupler
Connect the other gas line to the dNim module
Product lines:
For Nitro product,usegreen3/16”-5/16”tubebetweenthekegcouplerviatheltertothetwo
way divider. Continue with green tube from the two-way divider to the dNim and from the dNim
to the Tap.
For the Non-Nitro product, use at least 1½m of pink 3,3mm - 5/16” tubing from the two-way
divider to the tap.
Connect the power plug to an electric outlet (230V~).
Check on the electronic thermostat display that the temperature is set to +2°C.
Make sure all tubing are seated and secured properly and that the taps are closed.
Open the gas bottle by turning the wheel counterclockwise until it’s fully open.
Using a hex key, set an initial pressure on the regulator for the keg on 2,5bar and dNim to an
initial pressure of 1,6 Bar, see Image 2
For higher head foam, increase the pressure to the dNim, and vice versa.
Place a bucket under the taps and connect the Keg.
Open the taps, one at a time, and purge all gas out until there is a steady stream of Coffee.
Close the taps.
