Assemble the continuous-flow heater as shown in the
illustrations. Observe the information in the text.
S a fe ty in f or m a ti o n
I
The continuous-flow heater must only be connected
and started up by an authorized technician.
I
The statutory regulations of the respective country, as well
as those of the local electricity and water suppliers must
be adhered to.
I
The continuous-flow heater is an appliance of protection
class I and must be connected to the protective earth
conductor.
I
The unit must be durably connected to permanently
installed lines.
I
In order to meet the current safety requirements, an
all-pole disconnecting device must be present on the
installation side. The contact gap must be at least 3 mm.
I
The continuous-flow heater is suitable for enclosed
(pressurized) operation only.
I
The tap fittings must be permitted for operation with
enclosed (pressurized) continuous-flow heaters.
I
The continuous-flow heater can be operated by
connecting it to a cold water line or a pre-warmed water
line (solar energy unit). Please observe all relevant
technical data and special accessories required.
I
The continuous-flow heater is suitable for connection to
DVGW-tested plastic pipes.
I
The continuous-flow heater must only be installed in
a frost-free room.
I
Prior to installation, the electric connecting cord
must be disconnected from the mains voltage and
the water supply cut off!
I
Only connect the electric supply after the water
supply.
I
When making holes in the rear wall, only make the
number of holes required for installation. If the appliance
is reinstalled, any holes that are not used must be made
watertight.
I
Live components must not be touched subsequent to
installation.
As se mb ly
I. Unpacking/removing the
housing cover
I
Unpack the appliance and check for transportation
damage.
I
Dispose of the packaging and, where applicable, the old
appliance, in an environmentally conscious manner.

II. Preparation for assembly
I
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-mounted assembly
I
The continuous-flow heater must be fitted securely to the
wall. If required, secure the appliance using the lower
adjusting screws.
I
The distance from the wall is variable. This allows you to
compensate for any unevenness in the wall surface.
I
The sleeve must fit tightly round the connection cable. If
the sleeve is damaged during installation, the holes must
be sealed water-tight.
IV. Water supply
I
The flow-through heater must be vented. Open the
warm water tap completely and allow to flow through
for one minute.
V. Electric supply/Assembly
I
The mains connection terminal can either be mounted
above or below. At least 40 mm of the connecting cord's
insulating jacket must be clamped unside the appliance.
I
Plug the flat strip cable from the operating unit into the
regulating unit before closing the cover.
Startup/Additional information
VI.
I
For low water line pressure, remove the flow limiter
(see Fig. A).
I
Instruct the user with regard to the operation of the
continuous-flow heater.
If the flow-through heater does not achieve adequate
A
flow as a result of water line pressure that is too low
in your house installation, remove the flow limiter.
Priority circuit for the combination with electro-
B
storage heating units:
For operation with the priority circuit, a special load
reducing relay BZ 45L20 (special accessory) is
required. Other already existing load reducing relays
with the exception of electronic load reducing relays
could cause malfunctions.

The power limit has been reached. The
flow regulating valve reduces the water
flow rate.
During the first start-up or after a power
failure, a brief cold-water rinse-through
phase is automatically carried out (appli-
ance protection).
