1. Cutting through cold water pipe
Close the main shut-off valve. Cut through
the cold water pipe at a suitable point.
2. Fitting T-joint
Fit a T-joint (not supplied) between the
pipe sections.
3. Fitting pressure reducing valve
Connect the pressure reducing valve to
the T-joint with a piece of copper piping
(Ø 15 mm). Note: The pressure reducing
valve must be fitted in the correct
direction (see image).
4. Fitting the inlet combination
Connect the inlet combination to the
pressure reducing valve. The inlet
combination can be fitted in any direction,
but the grey funnel must always be
pointing straight downwards. Close the
stop valve on the inlet combination, open
the main shut-off valve and check for
leaks.
Connecting water
• The PRO7 operates under mains water pressure and must always be fitted with the supplied
inlet combination and pressure reducing valve.
• The Nordic single tap, the Fusion tap or the Flex 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 the figure at step D4).
