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 exclusivelydesigned for qualified contractors.■ Work on electrical equipment must

only be carried out by a qualified elec-trician.

Regulations

Observe the following when working onthis system■ National installation requirements■ Legal instructions regarding the pre-

vention of accidents■ Legal instructions regarding environ-

mental protection

■ The Code of Practice of relevant tradeassociations

■ All current safety regulations asdefined by DIN, EN, DVGW, VDE andall locally applicable standards.a ÖNORM, EN and ÖVEc SEV, SUVA, SVTI, SWKI and

SVGW

Working on the system

■ Isolate the system from the power sup-ply and check that it is no longer 'live',e.g. by removing the separate fuse orby means of a main isolator.

■ Safeguard the system against unau-thorised reconnection.

Application

The Pyromat Eco, type PMEA boiler canbe used for the following:■ Central heating via a central heating

system■ DHW heating

Any use that differs from or goes beyondthis is considered inappropriate.

NoteThe Pyromat Eco, type PMEA must onlybe operated by authorised and trainedpersonnel.

Occupational safety

DangerIncorrectly executed electricalinstallations can result in injuriesfrom electrical current and inappliance damage.

Connect the power supply andimplement all safety measures(e.g. RCD circuit) in accordancewith the following regulations:■ IEC 60364-4-41■ VDE regulations [IEE or local

regulations]■ Technical connection require-

ments of the local power supplyutility

DangerContact with 'live' componentscan lead to serious injury fromelectric current. Some compo-nents on the PCBs will remain'live' even after the power supplyhas been switched off.■ Isolate the system from its

power supply (e.g. at a sepa-rate MCB/fuse or mains isola-tor), check that there are nomore 'live' currents and safe-guard against reconnection.

NoteIn addition to the control circuit,there may be several power cir-cuits.

■ Prior to removing the boilercovers, wait at least 4 min. topermit the voltage to decay.

DangerThe absence of componentearthing can result in seriousinjury from electrical current andin component damage in theevent of an electrical fault.■ Always reinstate all earth con-

nections.■ Boiler and pipework must be

grounded to the equipotentialbonding of the building.

Working on the boiler

! Please notePrior to commissioning and fol-lowing repair or maintenancework check that the boiler is in an appropriatecondition.

■ Wear appropriate protective clothing(e.g. safety boots) in compliance withapplicable regulations on accidentprevention and in line with trade asso-ciation recommendations.

Unloading and transportation

NoteBefore unloading, have the recipientcheck the consignment for possibledamage. Note down any damage on thedelivery note and notify the haulage con-tractor.

! Please noteJolting movements can damagethe combustion chamber lining.Ensure the boiler is not subjectedto excessive jolting movementsduring handling and installation.

Note■ The pre-installed lifting eye can be

used to transport the boiler.■ The boiler can be moved inside its

packaging subject to the physicalspace allowing such handling.

■ Wherever possible, transport theboiler to the installation location withthe shipping protection fitted.

■ Only transport the boiler with fittedshipping feet on a pallet truck.
