F58F DUCT MOUNTED ELECTRONIC AIR CLEANER
Determine Duct Design Requirements
The air cleaner is adaptable to all new or existing forced air
heating, cooling and ventilating systems used in residential
applications. Transitions, turning vanes, or offsets may be
needed in some applications for effective operation.
Transitions
Transitions are needed when the duct is a different size
than the air cleaner cabinet. Gradual transitions reduce air
turbulence and increase efficiency. Limit expansion to no
more than 20 degrees (about 4 in. per running foot
[100 mm per 300 linear mm]) on each side of a transition
fitting. See Fig. 2.
Fig. 2. Change duct size gradually to
minimize turbulence.
Turning Vanes
If the air cleaner is installed close to an elbow or angle
fitting, install turning vanes inside the angle to distribute
airflow more evenly across the face of the cell. See Fig. 3
Offsets
If the duct connection to the furnace in a side installation
allows less than 7 in. (178 mm) for mounting the air
cleaner cabinet, add an offset to the elbow. See Fig. 3.

INSTALLATION
When Installing this Product…
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazard-
ous condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for
your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
WARNING
Electric Shock Hazard.
Can cause electrical shock or
equipment damage.
Do
not connect to power before installation
is complete.
Unpack Electronic Air Cleaner
J
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, one or two electronic cells and
prefilters, access door with test button, and homeowner
literature package.
J
W8600F (optional), mounting hardware and installation
literature must be ordered separately.
Clean Blower Compartment
J
Remove and discard the existing furnace filter.
J
Thoroughly clean the blower compartment.
J
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.
J
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.
Fasten Cabinet To Furnace
NOTE:
This procedure shows a side installation on a
typical highboy furnace. You may need to alter
the procedure to fit your application.
J
Remove and set aside the access door, electronic cells
and prefilters.
J
Align the cabinet with the return air opening.
J
Create opening in furnace to match air cleaner
cabinet opening.
J
Install a transition if the furnace and air cleaner
openings are different sizes. See Fig. 2.
J
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.
J
If a W8600F is used, first attach the wires to the
W8600F and then attach the wires to the air cleaner
power box terminal board. See Fig. 4 and the W8600F
installation literature, form 69-1200.
