Installation instructions

These installation instructions apply to various continuous-
flow heater appliance models. Therefore the illustrations
may deviate from the device you bought.
Install the appliance as shown in the illustrations. The
illustrations can be found in the centre of the instruction
manual. Observe the instructions in the text.
Unpacking/Removing the cover
Unpack the appliance and check for transport damage. If
any components are damaged, then do not connect the
Check that your appliance contains all components in-
cluded in the scope of delivery: appliance, installation
set with supplementary sheets, installation instructions,
operating instructions.
Please dispose of the packaging and the old appliance in
an environmentally-friendly manner.
When removing the cover from either a Type A or
Type B appliance, please note the following:
The Type A cover is fastened by a central closure behind
the service flap.
The Type B cover is attached by two screws located on
the underside of the cover.

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.
Install the water connection nozzles according to the in-
structions on the supplementary sheet.
The electrical connection cable can either be guided in at
the top (X) or bottom (Y).
The rear panel must lie against the cold water connection
nozzle in the position provided for such (Fig. II., 8.).

Wall mounting

The grommet must tightly surround the connection cable.
If it is damaged during mounting, the openings must be
provided with watertight sealing.
The electrical supply terminal can be fitted at the top (X)
or bottom (Y). The sheath of the connection cable must
extend for at least 40 mm into the appliance.
The distance to the wall is variable. You can compensate
for any unevenness of the wall's surface. With a distance
to the wall of 8–16 mm, insert the spacer and install the
extender (Fig. III., 3. – 5.).
The appliance must be mounted securely on the wall. If nec-
essary, attach it at the lower adjustable screws (Fig. III., 6.).

Water connection

Connect the water supply, then open the cold water supply.
The appliance must be vented. To do so, open the
warm water tap fully and flush out the appliance
thoroughly for 1 minute.
Electrical connection/Mounting
Only for appliances with power selector switches:
Set the power using the power selector switch before
connecting the wires to the mains connection terminal:
Nominal output power left, reduced output right
(Fig. V., 1.) and the set output marked on the ratings plate.
Screw the wires tightly into the mains connection terminal.
Switch on the safety limiter (Fig. V., 3.)
Install the cover – according to either Type A or B in-
structions (Fig. V., 4. – 7.).
Installation note
The installation of non plug-in ready appliances must
be undertaken by the respective utility operator or by
a qualified specialist company, who can also assist you
when you are requesting the approval of the utility
company for installation of the appliance.
The device is compliant to IEC 61000-3-12.
First start-up
Switch on the fuses.
Setting the temperature.
Initial rinsing: Open the warm water tap fully and allow
water to flow for at least 1 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.
Explain the operation of the appliance to the user.
Additional information
If the appliance does not have sufficient water flow due
to low water line pressure in your domestic plumbing sys-
tem, remove the flow-rate limiter (Fig. VII., 1. – 3.).
Priority circuit for the combination with electrical storage
For operation with a priority circuit, a special load shed-
ding relay BZ 45L21 (special accessory) is required. Other
existing load shedding relays, with the exception of elec-
tronic load shedding relays, may malfunction (Fig. VII.,
Wiring diagram).
The control electronics must be coded when operated
with a load shedding relay. Remove the keying nose on
the electronics (Fig. VII., 4.).
