Mounting The F300 Electronic Air Cleaner - Honeywell F300 Professional Installation Manual

Mounting the F300 Electronic Air Cleaner

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 prefilters, two media postfilters (on select models), access door and product data literature.
STEP TWO: Clean Blower Compartment
a. Remove and discard the existing furnace filter.
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 prefilters and media postfilters.
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 firmly 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 first be fitted in
the furnace opening. Either drill holes and fasten with sheet metal
screws or rivets, or use slip joints.
