manual carefully, then act accordingly! Store for future 
reference.

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

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.

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.

VI.

Startup/additional information

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.

A

If the continuous-flow heater does not have sufficient 
water flow due to low water line pressure in your do-
mestic plumbing system, remove the flow-rate 
limiter.

B

Priority circuit for the combination with electrical 
 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.

C

The control electronics must be coded when operated 
with a load shedding relay.
