Installation and basic setup guide
Place the Nico unit on an appropriate bench. Depending on the layout of the surrounding area, it
might be necessary to drill a hole (~Ø60mm) below the unit to allow for the tubing.
Connect the power plug to an electric outlet (230V~).
Mount the gas regulator securely on to a wall and connect it to the gas bottle via the high
pressurehose,makesurethehighpressurehoseisrmlyconnected,seeimage
If the tubing harness isn’t already connected to the Nico unit, connect the tubes located in the
bottom of the unit, see Image 1
There are 3 inlets, one for gas and 2 for coffee
Connect the grey gas tube to the gas inlet
Connect the pink tube to the middle inlet, for Black Coffee
Connect the green tube to the left side (when viewed from the front of the unit) for Nitro Coffee
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 the pressure on the two regulators for the keg and dNim to an initial
pressure of 2,8 Bar, see Image 2
To set the initial level of nitro injection, open the lid to access the control panel and turn the
adjustment wheel clockwise to fully close the valve, then open it back up two full revolutions
(2x360°) Image 3
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.
To adjust the head height of the nitro coffee, turn the injection valve counterclockwise (+) to
increase head height and clockwise (-) to decrease head height.
