ACCESSORIES
EVAPORATOR RETURN AIR PLENUM
Evaporator return air plenums are available for installations where it is required to
duct air to the inlet of the evaporator. The evaporator return air plenum allows the
user to connect round duct (flexible or rigid) to the return air intake to reduce air noise
and increase the number of options for solving difficult application problems. The
plenum attaches to the front of the unit, replacing the return air grille. Refer to the
table below for configuration and application information.

NOTE — When an evaporator return air plenum is installed, it is recommended to set
