Non-Ducted Return Air Closet Installation
The cabinet can be installed in a closet with a false bottom to form
a return air plenum, or mounted on an open platform inside the
closet. Platform should be high enough to provide a free (open)
area for adequate return airflow into the bottom of the cabinet.
The open area can be on the front side or a combination of front
and sides, providing there is clearance on the sides between
cabinet and closet. Refer to ACCA Manual D for sizing and free
area recommendations.
NOTE: Local codes may limit application of systems without a
ducted return to single story dwellings.
Horizontal Left and Right Installations
Coil cabinets that are shipped with the horizontal drain pan
installed are set up for horizontal left hand airflow. They must have
the drain pan repositioned for right hand airflow. Refer to coil
installation manual.
CAUTION
Afield fabricated auxiliary drain pan, with a separate drain is
REQUIRED for all installations over a finished living space or
in any area that may be damaged by overflow from the main
drain pan. In some localities, local codes require an auxiliary
drain pan for ANY horizontal installation.
