 Permanentmagnetmotor.Theshaftmustbeblockedduringrepairsandmaintenanceofthe
electricsystem(themotor
generateselectricitybyro tation–forexamplethatthewindand
thermicdrivesthefan/motor).

n.Theessentialcharacteristicsoftoolswhichmaybefittedtothe
machinery
ThesubjectintheMachineryDirectiveabouttoolsonthemachinedoesnotexistfortheTIMEandDVair
handlingunits,becausethosetoolsdoesnotexist.
o.Theconditionsofstabilityduringuse,transportation,assembly,
dismantlingwhenoutofservice
Theunitmustalwaysbehandledinanuprightpositi on.Nevertiltanysectionmorethan15degrees.If
sectionsmustbetiltedmorethan15degrees,sectionswithfansorrotatingexchangersthatcanbedrawn
outforservicemustbesecuredcarefully.
Duringtransportation,installation,dismantlingorotherhandling,
itmustbesecuredthatallcomponentsin
theunitareproperlyfastenedandwithadditionalattentiontothecontrolofanti‐vibrationmountsunder
thefansthattheyareundamaged.Themountingandsmoothrunningofthefansmustbecontrolledand
handledwithgreatcare.
o.1Installedreliabletoavoidunitstobetiltedormovedbytheanystorm.
Unitsinstalledonroofsandotherplaceswiththeriskofheavywindsmustbeinstalledreliabletoavoid
thattheycanbetiltedormovedbytheanystorm.Thebaseframeisprovidedwithholesthatareintended
forfasteningbysufficientboltsandfittingssuppliedbytheinstaller.

o.2Transportofsectionwithcoolingcompressorunit
Duringtransportation,theunitsection –DVUandDVU‐C‐mustalwaysbeintheuprightpositionortilted
lessthan30˚.Ifitisnecessarytotilttheunitmorethan30˚,thesuctionpipeofthecompressormustpoint
upwardstopreventtheescapeofoilfr omthecompressorsump.
o.3Disposalofthecoolingcompressorsystem‐typeDVUandDVU‐C
PriortothedisposaloftheDVUorDVU‐Cunitsection,therefrigerantinthecoolingsystemmustbe
drainedoffbyaskilledtechnicianfromacertifiedcompany. Aftercorrectevacuationoftherefrigerant,the
disposaloftheDVUorDVU‐Cunitsectionissimilartothedisposal
oftherestoftheairhandlingunit.
o.4Genereldisassembly–sharpedges
Payattentiontoseveralsharpedgesduringdismantlinganddisposaloftheunit.Toavoidinjury,CE‐marked
cut‐resistantglovesaswellashelmetmustbeused.Themeasuresaredescribedfurtherinthe
Maintenance,DismantlingandDisposalManual.
