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.

Important information

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.

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.
