vertically in return duct near furnace.
NOTE: When more than one media air cleaner is used, each
air cleaner requires a separate RF AIRWATCH®, if
communication is desired with all units.

Determining Sheetmetal Requirements

The media air cleaner is adaptable to all new or existing forced
air heating and cooling systems used in residential
applications. Transitions or turning vanes may be required in
some applications for effective media air cleaner operation.
Transitions
Transitions are needed when the duct is a different size than
the media air cleaner cabinet. Follow these guidelines when
fabricating:
1.Use gradual transitions to reduce air turbulence and
increase efficiency. See Fig. 12.
2.Use no more than 20 degrees (about 4 in. per running ft.
(100 mm per 300 linear mm)) of expansion on each side of a
transition fitting.

Turning Vanes

If the media air cleaner is installed next to an elbow or angle
fitting, add turning vanes inside the angle to distribute airflow
more evenly across the face of the media. See Fig 13.
Offsets
If the duct connection to the furnace in a side installation allows
less than 7 in. (178 mm) for mounting media air cleaner
cabinet, attach an offset to the elbow. See Fig. 14.
