9.2 Water installation
- Never operate with preheated water.
- No safety valve is required.
- Safety valves are not permissible in the DHW pipe.
f
Flush the water line thoroughly.
f
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").
f
Increase the mains water pressure if the required flow rate is
not achieved with the draw-off valve fully opened.
Taps/valves
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:
Stainless steel pipe, copper pipe or plastic pipe
!
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
f
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.
f
Secure the back panel at the bottom with two additional
screws.
