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
