Assemble the continuous-flow heater as shown in the
illustrations. Observe the information in the text.
Safety information
The continuous-flow heater must only be connected
and started up by an authorized technician.
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 an appliance of protection
class I and must be connected to the protective earth
conductor.
The unit must be durably connected to permanently
installed lines.
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.
The continuous-flow heater is suitable for enclosed
(pressurized) operation only.
The tap fittings must be permitted for operation with
enclosed (pressurized) continuous-flow heaters.
The continuous-flow heater must only be connected to
a cold-water pipe.
The continuous-flow heater is suitable for connection to
DVGW-tested plastic pipes.
The continuous-flow heater must only be installed in
a frost-free room.
Prior to installation, the electric connecting cord
must be disconnected from the mains voltage and
the water supply cut off!
Only connect the electric supply after the water
supply.
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.
Live components must not be touched subsequent to
installation.

II.
III.
The continuous-flow heater must be fitted securely to the
wall. If required, secure the appliance using the lower
adjusting screws.
The distance from the wall is variable. This allows you to
compensate for any unevenness in the wall surface.
The sleeve must fit tightly round the connection cable. If
the sleeve is damaged during installation, the holes must
be sealed water-tight.
IV.
The flow-through heater must be vented. Open the
warm water tap completely and allow to flow through
for one minute.
V.
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.
VI.
For low water line pressure, remove the flow limiter (see
Supplementary Information A).
Instruct the user with regard to the operation of the
continuous-flow heater.
Separate the required language version from the rest of
the operating instructions. This can be kept in the swing-
out control panel of the continuous-flow heater.

Startup
If the flow-through heater does not achieve adequate
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-
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.
