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 switch cut-out.

ACCESSORIES
CONDENSER RETURN AIR PLENUM
NOTE — When installing the condenser return air plenum with a ceiling panel kit,
allow for a minimum separation distance of 2 feet between the unit discharge duct
and the return air duct. It is also recommended to direct the condenser discharge
air away from the condenser return air duct.
Condenser return air plenums are available for installations where it is required to
duct air to the inlet of the condenser. The plenum easily fits into place on the back
of the unit, and is provided with a flange for connecting 12-inch or 16-inch flexible
ducting. A condenser return air plenum can substantially reduce air noise and
allow the unit to operate without drawing condenser air from the conditioned
space. Refer to the table below for configuration and application information.
