General safety instructions

We guarantee trouble-free function and operational reliability
only if the original accessories and spare parts intended for the
appliance are used.
Material damage
!
Observe the maximum inlet temperature. The appliance
can be damaged by higher temperatures. You can limit
the maximum inlet temperature by installing a central
thermostatic valve (see chapter "Appliance description /

Accessories").

Instructions, standards and regulations

Note
Observe all applicable national and local instructions and
regulations, e.g. DIN 1988 / DIN EN 806 in Germany.
- 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, observe the lowest electrical water resistance (see
chapter "Specification / Application areas"). Your water
supply utility will advise you of the specific electrical water
resistance or conductivity.
