Connecting water
• Note: The COMBI E operates under mains water pressure and must always be
fitted with the supplied inlet combination and pressure reducing valve.
• 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).
1 Fitting pressure
reducing valve
Close the main shut-off valve. Fit the
pressure reducing valve to the T-joint
and subsequently to the cold water pipe
(Ø 15 mm). NOTE: The pressure reducing
valve must be fitted in the correct direc-
tion (see image). Fit the cold water inlet
hose of the mixer tap or the Fusion tap
to the T-joint with the inlet hose screen.
2 Fitting inlet
combination
Connect the inlet combination to the
pressure reducing valve with a piece of
copper piping (Ø 15mm).
3 Fitting mixing
valve
Connect the mixing valve to the inlet
combination with the large fibre washer
supplied. Allow for the temperature
setting knob. Connect the hot water
inlet hose of the mixer tap or the
Fusion tap to the mixing valve with the
inlet hose screen.
4 Temperature
setting
Turn the temperature setting knob of
the mixing valve to the temperature
you require (between 50°C and 60°C).
