INSTALLATION
7. Safety
Only a qualified contractor should carry out installation, commis-
sioning, maintenance and repair of the appliance.
7.1

General safety instructions

We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
Flow pressure
If the flow rate is not sufficient to switch on the appliance even
when the tap is open, remove the flow limiter and replace it with
the plastic profile washer supplied.
If required, the pressure in the water installation can also be
raised.
Note
If a thermostatic valve is used, you must not replace the
flow limiter with the plastic profile washer.
Material losses
!
Observe the maximum inlet temperature. Higher tem-
peratures may damage the appliance. You can limit the
maximum inlet temperature by installing a central ther-
mostatic valve.
7.2

Instructions, standards and regulations

Note
Observe all applicable national and regional regulations
and instructions.
- The protection rating IP 25 (hoseproof) can only be ensured
with a correctly fitted cable grommet.
- The specific electrical resistance of the water must not fall
below that stated on the type plate. In a linked water net-
work, factor in the lowest electrical resistance of the water
(see chapter "Specification / Application areas"). Your water
supply utility will advise you of the specific electrical water
resistance or conductivity.

Preparations

f Flush the water line thoroughly. f
Taps/valves
f Use appropriate pressure-tested taps. Open taps are not f
permitted.
A safety valve is not required.
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 account
the maximum inlet temperature and the maximum pres-
sure (see chapter "Specification / Data table").
Flow rate
f Ensure that the flow rate (see chapter "Specification / Data f
table", On) is sufficient for switching on the appliance.
f Increase the mains water pressure if the required flow rate is f
not sufficient with an open draw-off valve.
Flexible water connection lines
f If the appliance is installed with flexible water connection f
lines, ensure that the pipe bends do not become twisted.
Pipe bends have a bayonet fitting and are installed inside the
appliance.
f Secure the back panel with an additional screw at the f
bottom.
