Installation instructions

Install the continuous-flow heater as described in the
illustrated section. Observe the instructions in the text.
The illustrations can be found in the centre of the instruction
manual.
Installation
Unpacking/Removing the cover
I.
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.
Water connection
IV.
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.
Electrical connection/Mounting
V.
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.
Installation note
The installation of non plug-in ready appliances must be
undertaken by the respective utility operator or by a quali-
fied specialist company, who can also assist you when
you are requesting the approval of the utility company for
installation of the appliance.

Startup/additional information
VI.
The device is compliant to IEC 61000-3-12.
First start-up
Switch on the fuses.
Set the temperature.
Start 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.
The factory-installed flow rate limiters are designed for
an ouflow temperature of approx. 42 °C (e. g. bathing and
hand-washing temperatures). If higher outflow tempera-
tures are desired, install the separately enclosed flow rate
limiter (Fig. A).
Explain the operation of the continuous-flow heater to
the user.
If the continuous-flow heater does not have sufficient
A
water flow due to low water line pressure in your do-
mestic plumbing system, remove the flow-rate
limiter.
Priority circuit for the combination with electrical
B
storage heaters:
For operation with a priority circuit, a special load
shedding relay BZ 45L20 (special accessory) is re-
quired. Other existing load shedding relays, with the
exception of electronic load shedding relays, may
malfunction.
The control electronics must be coded when operated
