Warning Installation andmaintenanceofthe unit must beperformed onlyby qualifiedpersonnel who have

knowledgewithlocalcodesandregulations,andexperiencewiththistypeofequipment.Mustbeavoidedthe

Handling Careshouldbetakentoavoidroughhandlingorshockduetodroppingtheunit.Donotpushorpull

theunitfromanythingotherthanthebaseframe.Neverallowtheunittofallduringunloadingormovingas

thismayresultinseriousdamage.Tolifttheunit,ringsareprovidedinthebaseframeoftheunit.Spreader

barandcablesshouldbearrangedtopreventdamagetocabinet.

Location Theunits areproduced foroutdoor installation onroofs, floorsor belowground levelon condition

thattheareaisfreefromobstaclesforthepassageofthecondenserair.Theunitshouldbepositionedonsolid

foundationsandperfectlyleveled;inthecaseofinstallationonroofsorfloors,itmaybeadvisabletoarrange

theuseofsuitableweightdistributionbeams.Whentheunitsareinstalledontheground,aconcretebaseat

least 250 mm wider and longer than the unit’s footprint should be laid. Furthermore, this base should

withstandtheunitweightmentionedinthetechnicaldatatable.

Space requirements Theunitsareair-cooled,thenitisimportanttorespecttheminimumdistanceswhich

guarantee the best ventilationof the condensercoils. Limitations ofspace reducing theair flow could cause

significantreductionsincoolingcapacityandanincreaseinelectricityconsumption.

Todeterminate unitplacement,carefulconsiderationmust begiventoassureasufficientair flowacross the

condenserheattransfersurface.Twoconditionsmustbe avoidedtoachievethebestperformance:warmair
