consistsofcoppertubesandaluminiumns.
Warning
Thecoolingcoilmustnotbeusedfordirect-expansionrefrigerant.
Forairow,waterowandothertechnicalparticulars,seetabellsinchapter4.
Thecoolershouldnotbeinstalledclosetoafanoutletoraductbend,sincetheairowacrossthecoil

Makesurethatthecoolerisinstalledsothatthennedcoil,driptrayandcondensateoutletareaccessible
forcleaning(chapter5).Theductcoolershouldbeinstalledinahorizontalduct,buttheairowmaybein
eitherdirection.Securetheductcoolertotheductsystembymeansofscrewsorslipjoints.
Thecondensateoutlet(posC)ingure2shouldbeconnectedacrossawatertrapinordertoavoid
