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 or about 4 in. per running foot (100 mm
per 300 linear mm) on each side of a transition fitting. See
Fig. 4.

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. 5.
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. 5.

INSTALLATION
When Installing this Product…
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
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
❑ 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.
❑ Order W8600F (optional), mounting hardware and
installation literature separately.
Clean Blower Compartment
❑ Remove and discard the existing furnace filter.
❑ Thoroughly clean the blower compartment.
❑ 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.
❑ 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.
❑ Remove and set aside the access door, electronic cells
and prefilters.
❑ Align the cabinet with the return air opening.
❑ Create opening in furnace to match air cleaner cabinet
opening.
❑ Install a transition when the furnace and air cleaner
openings are different sizes. See Fig. 4.
❑ 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.
