ACCESSORIES
EVAPORATOR RETURN AIR PLENUM, 2DEP
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 plenums allow 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 cooling problems. The plenum attaches to the front of
the unit, replacing the return air grill. Refer to the table below for configuration and applica-
tion information
