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.
