1 Install T-piece
Close the main shut-off valve. Fit the
pressure reducing valve ‘cold’ to the
T-piece and then on the cold water pipe
(Ø 15 cm). Pay attention to the installation
order. Connect the cold water hose of the
mixer tap, the Fusion tap or the Flex tap to
the T-piece with the hose filter.
2 Fit inlet combination
Fit the pressure reducing valve ‘warm’ to
the hot water pipe. In case of a 15 mm
pipe, replace the 15-12 mm adaptor in the
coupler with the 15 mm olive.
3 Fit pressure reducing valve
Fit the coupler to the hot water pipe. In
case of a 15 mm pipe, replace the 15-12 mm
adaptor in the coupler with the 15 mm olive.
4 Fit mixing valve
Fit the pressure reducing valve ‘warm’ to
the hot water pipe. In case of a 15 mm
pipe, replace the 15-12 mm adaptor in the
coupler with the 15 mm olive.

Connecting water
• The COMBI+ operates under mains water pressure and must always be fitted with the supplied
inlet combination.
• The boiling-water tap must be installed according to the locally applicable regulations.
• The inlet combination will release drips of expansion water while the water in the tank is
heating up in order to regulate the pressure inside the tank.
• Position the inlet combination as high as possible to create a sufficient height distance
between the inlet combination and the point where the waste hose connects to the waste pipe.
This is necessary to allow the expansion water to flow away and to prevent water from backing
up from the waste pipe (see figure at step D4).
