Water connection / draining
The water supply must be connected according to all valid regulations as well as national stipula-
tions. If the machine is connected to a newly installed water pipe, the pipe and the supply tube
must be thoroughly rinsed so that no dirt particles can enter the machine. The coffee maker must
be connected to an installed drinking-water pipe with shutoff valve. The machine is installed by
using the mounted pressure tube and the G 3/8“ screw at the pressure relief component mount-
ed to the tap (set to 0.3 MPa (3 bar)). If the machine is attached to a water drainage system, the
supplied temperature-resistant drain hose must be connected to the drip try and siphon. It must
be rmly attached to the drain and slanted at a downward angle (so that the water can ow
downward).
Always use the new hoses supplied with the machine (fresh-/drain water hose)! Do not use old
fresh- and drain water hoses!
The water must be free of contaminants and the chlorine content may not exceed 100 mg/l. Do
not use pure reverse osmosis (RO) water or any other type of aggressive water. The carbonate
hardness may not exceed 5 – 6°dKH (German carbonate hardness) or 8 – 10°fKH (French car-
bonate hardness) and the total hardness must be always higher than the carbonate hardness.
The minimal carbonate hardness is 4°dKH or 7°fKH. The pH value must be between 6.5 – 7.
Water inlet pressure
Recommended: 0.1 – 0.3 MPa (1 – 3 bar)
Maximum: 0.6 MPa (6 bar)
Wassereingangstemperatur
Minimum: 10 °C
Maximum: 30 °C
We recommend setting the pressure relief valve to 3 bar!
