1 Cold water inlet
2 DHW outlet
Note
Mount the appliance on the wall. The wall must have
sufficient load bearing capacity.
9.2 Water installation
- No safety valve is required.
- Safety valves are not permissible in the DHW pipe.
Flush the water line thoroughly.
Ensure that the flow rate for switching on the appliance is
achieved (see chapter "Specification/ Data table", On). If the
flow rate is not achieved, remove the flow limiter (see chap-
ter "Installation/ Removing the flow limiter").
Increase the mains water pressure if the required flow rate is
not achieved with the draw-off valve fully opened.
Taps
Use appropriate pressure taps. Open vented taps are not per-
missible.
Note
Never use the shut-off valve in the cold water inlet to
reduce the flow rate. It is intended for shutting off the
appliance.
Permissible water line materials
- Cold water inlet pipe:
Pipes made from galvanised steel, stainless steel, copper or
plastic
- DHW outlet line:
Pipes made from stainless steel, copper or plastic
!
Material losses
If plastic pipework systems are used, take into account
the maximum inlet temperature and the maximum pres-
sure (see chapter "Specification/ Data table").
Flexible water connection lines
If the appliance is installed with flexible water connection
lines, ensure that the pipe bends with bayonet fittings do not
become twisted inside the appliance.
Secure the back panel at the bottom with two additional
screws.
