7.1

General safety instructions

All required steps up to and including commissioning must be
carried out by a qualified contractor. During this process, these
installation instructions must be observed.
We guarantee trouble-free function and operational reliability
only if the original accessories and spare parts intended for the
appliance are used.
7.2

Instructions, standards and regulations

Material damage
!
Observe the type plate. The specified voltage must match
the mains voltage.
WARNING Electrocution
Carry out all electrical connection and installation work in
accordance with applicable standards, including national
and regional regulations.
WARNING Electrocution
Only use a permanent connection to the power supply.
The appliance must be able to be separated from the
power supply by an isolator that disconnects all poles
with at least 3 mm contact separation.
Note
Water supply observe all applicable national and region-
al 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 used must not
fall below that stated on the type plate! In a linked water
network, observe the lowest electrical water resistance
(see chapter "Application areas"). Your water supply utility
will advise you of the specific electrical water resistance or
conductivity.

the most extreme operating and fault conditions that
could occur at the appliance; see chapter "Specification /
Fault conditions"
Note
Observe the plastic pipe manufacturer's instructions.
- Safety valves are not permissible in the DHW line of the in-
stantaneous water heater!

Appliance description

The bare wire heating system is suitable for hard and soft water
areas. The heater has low susceptibility to scale build-up.
The appliance is suitable for heating cold water or for reheating
preheated water. For temperatures, see chapter "Specification /
Data table".
The max. inlet temperature for reheating must not be exceeded.
There will be no reheating, if the inlet temperatures exceed this
maximum value.
Observe the "Max. inlet temperature". The appliance can be dam-
aged at higher temperatures. If a "central thermostat" is installed
(see chapter "Installation / Accessories"), you can limit the "Max.
inlet temperature".
The outlet temperature can be infinitely adjusted. The electronic
control unit enables automatic matching of the electrical output
corresponding to the selected temperature subject to the actual
throughput.
