Safety information
Risk of electric shock!
Switch off the mains voltage supply immediately if
a fault occurs.
We do not accept liability for damage resulting from
■
failure to heed these instructions.
The continuous-flow heater may only be connected
■
and put into operation by a qualified professional.
Never open the appliance without disconnecting the

power supply beforehand.
The statutory regulations of the respective country, as
■
well as those of the local electricity and water suppliers,
must be adhered to.
The continuous-flow heater is a Class

must be connected to the protective earth.
The appliance must be permanently connected to in-
■
stalled pipes. The conductor cross-section must comply
with the installed appliance power.
Caution
■ : Earthed water pipes may give the appearance of
a connected protective earth.
To guarantee compliance to relevant safety regulations,
■
an all-pole separator must be fitted during installation.
The contact opening must be at least 3 mm.
The continuous-flow heater is only suitable for closed
■
(pressurized) operation.
The tap and outlet fittings must be approved for operation
■
with closed (pressurized) continuous-flow heater systems.
The continuous-flow heater can be operated with cold or
■
pre-warmed water (for example, from a solar energy unit
water supply). Observe the technical data and the special
accessories for this purpose.
Only connect the continuous-flow heater to a cold water
■
line.
The continuous-flow heater may only be installed in a
■
frost-free room.
Disconnect the electrical connection cable from the
■
supply and shut off the water supply before connect-
ing the appliance!
Connect the water supply and then connect the elec-
■
trical supply.
Only make the openings which are required for instal-

Installation
I.
Unpacking/Removing the cover
Unpack the appliance and check for transport-related ■
damage.
Please dispose of the packaging, and if applicable, the old
■
appliance in an environmentally-friendly manner.
II.
Preparations for installation
Important: Only use the supplied installation set.
The supplied water connection nozzles must be installed!
Shut off water supply. The electrical connection (connec-
■
tion cable) must be disconnected from the power supply.
Unscrew the fuse or switch off the circuit breaker.
III.
Wall mounting
The continuous-flow heater must be mounted on the ■
wall. Attach it if necessary on the lower adjustable screws.
The distance to the wall is variable. You can compensate
■
for any unevenness of the wall's surface.
The grommet must tightly surround the connection cable.
■
If it is damaged during mounting, the openings must be
provided with watertight sealing.
IV.
Water connection
The continuous-flow heater must be vented. The ■
warm water tap must be opened and the appliance
must be flushed out thoroughly for 1 minute with
at least 6 litres of water.
V.
Electrical connection/Mounting
The electrical supply terminal can be fitted at the top or ■
bottom. The sheath of the connection cable must extend
for at least 40 mm into the appliance.
VI.
Startup/additional information
First start-up
Switch on the fuses.
■
Setting the temperature. ■
Starts rinsing: Open the warm water tap and allow water ■
to flow for at least 1 minute (flow-rate at least 6 litres per
minute). Only then (for safety reasons) will the appliance
begin to heat.
Tip: Should the appliance not start because of a reduced
flow-rate, remove the perlator, shower head or similar before
start and repeat the process.
Remove the flow-rate limiter (see Fig. A) with low water
■
pressure.
Explain the operation of the continuous-flow heater to
■
the user.
