Please follow these safety instructions closely to prevent accidents and mate-rial losses.

Safety instructions explained

DangerThis symbol warns against therisk of injury.

! Please noteThis symbol warns against therisk of material losses and envi-ronmental pollution.

NoteDetails identified by the word "Note" con-tain additional information.

Target group

These instructions are exclusively inten-ded for qualified contractors.■ Work on gas installations must only be

carried out by a registered gas fitter.■ Work on electrical equipment must

only be carried out by a qualified elec-trician.

Regulations

Observe the following when working onthis system:■ Statutory regulations regarding the

prevention of accidents■ Statutory regulations regarding envi-

ronmental protection

■ The Code of Practice of relevant tradeassociations

■ all current safety regulations asdefined by DIN, EN, DVGW, TRGI,TRF, VDE [and all local standards].a ÖNORM, EN, ÖVGW-TR Gas,

ÖVGW-TRF and ÖVEc SEV, SUVA, SVGW, SVTI,

SWKI, VKF and EKAS guideline1942: LPG, part 2

Working on the system

■ Isolate the system from the power sup-ply (e.g. by removing the separate fuseor by means of a mains isolator) andcheck that it is no longer 'live'.

■ Safeguard the system against recon-nection.

■ Where gas is used as the fuel, closethe main gas shut-off valve and safe-guard it against unintentional reopen-ing.

DangerIncorrectly executed electricalinstallations can lead to injuryfrom electrical current and resultin equipment damage.

Make the power supply connec-tion and implement all earthingmeasures (e.g. RCD circuit) inaccordance with the followingregulations:■ IEC 60364-4-41■ VDE requirements■ Requirements specified by

your local power supply utility■ Protect the power cable with

16 A max.

DangerThe absence of componentearthing in the system can lead toserious injury from electrical cur-rent if an electrical fault occurs.The equipment and the pipeworkmust be connected to the earthbonding of the house in ques-tion.

■ The main isolator (if installed) mustsimultaneously isolate all non-earthedconductors from the mains with a min-imum contact separation of 3 mm.

■ If no main isolator is installed, all non-earthed cables must be isolated fromthe mains by the upstream breakerwith at least 3 mm contact separation.

■ We additionally recommend installingan AC/DC-sensitive RCD (RCD classB ) for DC (fault) currents thatcan occur with energy-efficient equip-ment.
