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

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.
