Warnings
The following keywords are defined and can be used in this
document:
•NOTICE indicates a situation that could result in damage to
property or equipment.
•CAUTION indicates a situation that could result in minor to
medium injury.
•WARNING indicates a situation that could result in severe
injury or death.
•DANGER indicates a situation that will result in severe
injury or death.

1.2 Security Measures
Installation
▶ Installation must only be carried out
by an authorised service.
▶ IEC 60364-7-701 must be observed
when installing the appliance and or
electrical accessories.
▶ The appliance must be installed in a
room free from the risk of frost.
▶ First connect the appliance
hydraulically and fill with water, then
connect the power supply.
▶ During the installation isolate the
appliance from the power supply.
▶ In a closed, pressurised system of
installation, it is obligatory to install a
safety valve on the inlet pipe with a
rated pressure of 0.6 MPa (6 bar),
0.9 MPa (9 bar) or 1.0 MPa (10 bar)
(see the label), which prevents the
elevation of pressure in the boiler by
more than 0.1 MPa (1 bar) above the
rated pressure.
▶ Water may drip from the outlet
opening of the safety valve, so the
outlet opening should be set to
atmospheric pressure.
▶ The outlet of the safety valve should
be installed facing downwards and in
a non-freezing area.
▶ To ensure proper functioning of the
safety valve, the user should perform
regular controls to remove limescale
and make sure the safety valve is not
blocked.
Warnings in this document are identified by
a warning triangle printed against a grey
background.
Keywords at the start of a warning indicate
the type and seriousness of the ensuing risk
if measures to prevent the risk are not taken.
This symbol indicates important information
where there is no risk to people or property.

Installation and conversion
▶ Only permit an authorised service to
install this appliance.
▶ Do not install a stop valve between
the water heater and the safety valve,
because it will impair the pressure
protection of the heater!
▶ Before connecting it to the power
supply, the water heater must be
filled with water!
▶ The heater is equipped with an
additional thermal cut-off for
protection in case of failure of the
operating thermostat. In this case,
however, the temperature of the
water in the heater can reach up to
130 °C according to the safety
standards. During the water supply
installation, the possibility of
temperature overloads should be
taken into account.
▶ If the heater is to be disconnected
from the power supply, please drain
any water from the heater to prevent
freezing.
▶ Water can be drained from the heater
through the boiler inlet pipe. For this
purpose it is advisable to install a T-
element with an outlet valve between
the inlet pipe and safety valve.
▶ Neverobstructthe safetyvalve outlet.
▶ During the heat-up, water may be
expelled from the safety valve.
Maintenance
▶ Only authorised technicians are
permitted to service this appliance.
▶ Isolate the appliance from its power
supply before commencing any
maintenance work on the appliance.
▶ Customers are responsible for the
safety and environmental
compatibility of the appliance as well
as its maintenance.
▶ Use only original spare parts.
▶ To ensure compliance with all safety
requirements, a defective power
cable may only be replaced by an
authorised service.
▶ Please do not try to fix any defects of
the water heater on your own. Call the
nearest authorised service provider.
Instructing the customer (for the
installer)
▶ Instruct the customer in the function
and operation of this appliance.
▶ It is the responsibility of customers to
carry out regular maintenance and
inspections.
▶ The appliance must be serviced
annually.
▶ Inform customers that they must not
carry out any modifications or
repairs.

5 Installation
5.1 Important notes
The water heater shall be installed as close as possible to the
outlets. When installing the water heater in a room with a
bathtub or shower, take into account the requirements defined
in IEC Standard 60364-7-701 (VDE 0100, Part 701).
It has to be fitted to the wall using appropriate wall screws with
a minimum diameter of 8 mm. A wall with a poor load-bearing
capacity must be properly reinforced where the heater will be
installed. The water heater may only be fixed upon the wall
vertically.
To facilitate future service interventions, you are advised to
install the heater in accordance with the installation
measurements.
