Install Turning Vanes
! Mount turning vanes inside the elbow or angle fitting that is
directly against the air cleaner cabinet. See Fig. 7.
Fasten Cabinet To Ductwork
! Install a transition when the opening in the air cleaner
cabinet and the duct are different sizes. See Fig. 4.
! Fasten the other side of the cabinet to the elbow using
sheet metal screws, rivets, or slip joints as appropriate. If
drilling holes, use locking pliers to help hold the unit in place
during drilling. See Fig. 7.
Fig. 7. Connect ductwork to air cleaner. (Note turning
vanes. Locking pliers hold duct to air cleaner cabinet
during installation.)
Seal Joints
! Seal all joints in the return air system between the air
cleaner and the furnace to prevent dust from entering the
clean airstream. Use optional air cleaner cabinet gasket kit
(part no. 32002109-001), mastic or foil tape.
Position Cell Key
The electronic cell must always be installed so the ionizer
section is on the upstream side. A factory-installed cell key on
the bottom of the cabinet allows the cell to be inserted in only
one direction. If the arrow molded into the plastic key points in
the same direction as the airflow, the ionizer is always on the
upstream side.
If position of the key must be reversed, proceed as follows:
1. Remove the electronic cell.
2. Remove the screw holding the cell key in place. See Fig. 8.

3. Turn the key around and place it over the opposite holes.
