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.

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.

1. Read these instructions carefully. Failure to follow
2. Check the ratings given in the instructions and on
3. Installer must be a trained, experienced service
4. After installation is complete, check out product
Unpack Electronic Air Cleaner
Check that all components are included. The electronic
air cleaner is shipped assembled. The unit consists of a
M5626A
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.
W8600F (optional), mounting hardware and installation
literature must be ordered 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.

clearance required for the access door hinge.
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
