F300 ELECTRONIC AIR CLEANER

9 68-0240EF-5

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.

Remove the screw holding the cell key in place. See Fig. 8.

Fig. 8. Position of cell key determines orientation of cell

(arrow on key must point downstream).

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

The tab on the bottom fits into the larger hole, and the

screw fits into the smaller hole. Make sure the arrow on

the key points in the direction of the air flow (down-

stream).

4. Tighten the screw into the new hole.

5. Insert the electronic cell. The ionizer section will now be

on the air-entering (upstream) side of the cabinet.

Attach Cell Handles

Cell handles included with the air cleaner must be installed on

the end of the cell closest to the access door. To install:

1. Orient the cell as it will be when installed. The gray

contact board must be up and the airflow arrow stamped

into the cell must point downstream.

2. Hold the handle sideways and insert the solid tab on the

back of the handle into the slot in the cell. Turn the

handle 90 degrees clockwise to align the divided tab with

the square hole. See Fig. 9.

Fig. 9. Install the handle on the end of the cell closest to

the access door.

3. Insert the divided tab into the square hole.

4. Fold up the wedge and insert it into the divided tab to

lock the handle in place. If necessary, press with a blunt

instrument like the end of a pliers.
