be adhered to.
■
The instantaneous water heater is an appliance of protec-
tion class
I
and
must
be connected to the protective earth
conductor.
■
The unit have to be connected durably to the mains
electricity supply via an all pole disconnecting device with
contact gap must be at least 3 mm.
■
The instantaneous water heater is suitable for enclosed
(pressurised) operation only.
■
The tap fittings must be permitted for operation with
enclosed (pressurised) instantaneous water heaters.
■
The instantaneous water heater must only be connected

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 panel, only make the
number of holes required for installation. If the appliance
is reinstalled, any holes that are not used must be made
watertight.
■

installation.
Assembly
Unpacking/removing the
housing cover
■
Unpack the appliance and check for transportation
damage.
■
Dispose of the packaging and, where applicable, the old
appliance, in an environmentally conscious manner.
Preparation for assembly
Wall-mounted assembly
■
The instantaneous water 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 in the rear panel must fit tightly round the con-
nection cable. If the sleeve is damaged during installation,
the holes must be sealed water-tight.
Water supply
■
The flow-through heater must be vented. Open the
warm water tap completely and allow to flow through
for one minute.
Electric supply
■
The mains connection can either be mounted above or
below. At least 40 mm of the connecting cord’s insulating
jacket must be clamped inside the appliance.
Startup
■
For low water line pressure, remove the flow limiter (see
Supplementary Information A).
■
Instruct the user with regard to the operation of the
instantaneous water 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 instantaneous water heater.
Additional information
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 (special accessory) is required. Other
already existing load reducing relays with the
exception of electronic load reducing relays could
cause malfunctions.
