Installation Ducts Multiple Units
Where two or more DRY-O-TRON® units must be used for the same room, they should be installed in par-
allel, or have separate duct systems. Where two or more units share a duct, install dampers in the return
and supply ducts to prevent backflow should one unit be off for maintenance.
Do not duct two or more DRY-O-TRON® units in series, unless so instructed in writing by Dectron.
