LOCATING THE AIR CLEANER
Install the air cleaner in the return air duct (air entering
side) of the furnace or air handler as shown in figure 3.
Install the air cleaner in such a way that the face of the filter
is at a right angle to the air stream. Do not install the air
cleaner in the discharge or supply air duct system.
Allow 25” clearance in front of the air cleaner to accom-
modate removal of media filters or air cleaner cells. Refer
to figure 4 for dimensions.
If air handler return air, or air entering, opening is not large
enough to accommodate air filter, install a field fabricated
sheet metal transition. Transition reduction should be no
more than 4 inches per linear foot, creating an angle of
approximately 20 degrees. Refer to figure 4.

Atomizing spray-type humidifier (if used) must be installed
downstream of the air cleaner.
UV germicidal light (if used) must be installed a minimum
of 6 ft. from the air cleaner when the two are installed in

bend or turn in the air duct between the air cleaner and UV
light, a 3 ft. installation clearance is required between the
two.
