CONDENSER RETURN AIR PLENUM, 2DCP
CONDENSER RETURN AIR PLENUM, 2DCP
Condenser return air plenums are available for installations where it is required to duct air
to the inlet of the condenser. The plenum easily attaches with one screw to the back of
the unit, and is provided with flange(s) for connecting 12-inch flexible ducting. A con-
denser return air plenums can substantially reduce air noise and allows the unit to oper-
ate without drawing condenser air from the conditioned space. Refer to the table below
for configuration and application information.
NOTE — When installing the condenser return air plenum with the ceiling panel
kits, allow for a minimum separation distance of 2 feet between the unit discharge
duct and the return air duct(s). It is also recommended to direct the condenser
discharge air away from the condenser return air ducts.

To estimate the “equivalent feet” of condenser duct, add the length of the
condenser intake duct run and the length of the condenser discharge duct run,
and add 6 equivalent feet per bend in the duct. Make sure that you do not exceed
the rated E.S.P. to avoid shut down due to the high pressure cut-out
