9.2 Water installation

◦ A safety valve is not required.
» Flush the water line thoroughly.
» Ensure that the flow rate (see chapter "Specification /
Data table", On) for switching on the appliance is
achieved. If the flow rate is not achieved, remove the
flow limiter (see chapter "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 taps are not per-
mitted.
Note
Never use the shut-off valve in the cold water inlet
to reduce the flow rate. It is intended to shut off the
appliance.
Permissible water pipe materials
◦ Cold water inlet pipe:
Galvanised steel pipe, stainless steel pipe, copper
pipe or plastic pipe
◦ DHW outlet pipe:
Stainless steel pipe, copper pipe or plastic pipe
Material losses
!
If plastic pipework systems are used, take into ac-
count the maximum inlet temperature and the max-
imum pressure (see chapter "Specification / Data
table").
Flexible water connection lines
» If the appliance is installed with flexible water con-
nection lines, ensure that the bayonet fittings of
the pipe bends do not become twisted inside the
appliance.
» Secure the back panel at the bottom with two addi-
tional screws.
