Product Installation Manual

MOUNTING

The following procedure describes a typical side installation on an existing highboy furnace (Fig. 1). Alternate

procedures are noted as appropriate. Other changes in installation procedures may be necessary to complete

your installation.

STEP ONE: Unpack Electronic Air Cleaner

a. Check that all components are included. The electronic air cleaner is shipped assembled. The unit consists

of a galvanized steel cabinet, power supply with On-Off switch and neon light, two electronic cells, two metal

mesh prelters, two media postlters (on select models), access door and product data literature.

STEP TWO: Clean Blower Compartment

a. Remove and discard the existing furnace lter.

b. Thoroughly clean the blower compartment.

c. If possible, power vacuum the ductwork to remove accumulated dust in an existing home, or construction dirt

in a new home. The electronic air cleaner cannot remove dust that has settled in the blower compartment and

distribution ducts.

d. Check the edges of the furnace fan blades for dirt buildup and clean as necessary. The fan will not deliver the

rated cfm if the blades are dirty.

STEP THREE: Fasten the Cabinet to the Furnace

a. Remove and set aside the access door, electronic cells metal

mesh prelters and media postlters.

b. Align the cabinet with the return air opening.

c. Create an opening in the furnace to match the cabinet opening.

d. Install a transition when the furnace and air cleaner openings are

different sizes. See Transitions on page 5.

e. Place blocks under the cabinet so the unit is rmly supported and

level. The 5/8 in. (16 mm) mounting foot on the cabinet hinge plate

provides the minimum clearance required for the access door

hinge.

f. Attach the cabinet securely to the furnace. The unit can be

attached directly, as shown, or a starting collar can rst be tted in

the furnace opening. Either drill holes and fasten with sheet metal

screws or rivets, or use slip joints.
