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 fas-
teners, and be installed for either vertical or horizontal ducting. The standard dis-
charge grille is removed and the DDA is attached in the grille opening.
DDA-6
for PWC12, converts the evaporator discharge to a 6-inch diameter round
duct.
2DDA-10
for PWC18 and PWC24, converts the evaporator discharge to a 10-inch
diameter round duct.
2DDA-16
for PWC36 and PWC60, converts the evaporator discharge to a 16-inch
diameter round duct.
When used in conjunction with the evaporator return air plenum, DEP, the unit can
provide closed-loop cooling to and from a given space without the influence of any
outside air.
NOTE
— When a DDA/2DDA is installed, it is recommended to set the evaporator
blower speed to high, to avoid evaporator coil freeze-up.
