ACCESSORIES
DISCHARGE DUCT ADAPTER
Discharge duct adapters are available for applications where ducted evaporator discharge
is required. The adapters can be easily installed on the unit without fasteners, and be
installed for either vertical or horizontal ducting. The standard discharge grille is removed
and the DDA is attached in the grille opening.
2DDA-6 for PAC1211, converts the evaporator discharge to a 6-inch diameter
round duct.
2DDA-10 for PAC1811 and PAC2412, converts the evaporator to a 10-inch
diameter round duct.
2DDA-16 for PAC36 and PAC60 models, converts the evaporator discharge to a
16-inch round duct.
When used in conjunction with the evaporator return air plenum, DEP/2DEP, the unit can
provide closed-loop cooling to and from a given space without the influence of any
outside air.
