be carried out by persons who are authorised and who have successfully completed
qualifying
technical or vocational training
and who have taken part in advanced training sessions recog-
nised by the relevant responsible authorities for the specific activity. These include, in particular,
certified heating engineers, qualified electricians and HVAC specialists
who, because of
their professional training and
expert knowledge
, have experience in the professional instal-
lation and maintenance of heating systems, gas installations and heat water tanks.
WARNING!
Disregarding the following safety instructions may result in serious physical injury or death.

stand the dangers arising therefrom.
Children

user maintenance
must not be carried out by
children
without supervision.
●
Make up the power supply in accordance with IEC 60335-1, via a separator device which exhibits
contact separation in all poles with a contact opening distance that provide full disconnection in
accordance with overvoltage category III.

All the electrical work must only be carried out by electrically qualified experts and with consider-
ation of the local and national regulations, and the instructions in this manual.
Check that a suitable electrical circuit is being used.
Inadequate capacity of the power circuit or improperly executed connections can cause electro-
cution or fire.
●
The customer must install a pressure relief device with rated over-pressure less than 0.6 MPa
(6 bar). The connected drain line must have a continuous gradient and a free outlet in a frost-free
environment (see chap. 4.4).
●
Water may drip out of the drain line of the pressure relief device. The drain opening must be left
free to atmosphere.
●
The pressure relief device must be operated regularly in order to remove scale deposits and to
make sure it is not blocked.

The storage tank and hot water circuit can be drained. The instructions in chap. 11.1 must be
observed.
