PLANNING THE INSTALLATION
Application
The is used in a forced air heating, cooling, or ventilating
system. It removes airborne particles from the air circulated
through it. All models have an internal air flow switch to
operate the when the system blower is on.
Review Installation Requirements
The air cleaner should be installed where all the air passing
through the system circulates through it. The best location is
in the return air duct next to the blower compartment so the
air cleaner can help keep the blower motor and evaporator
coils clean.

IMPORTANT
Do not mount in the discharge air duct.
For most efficient air cleaning, airflow must be spread evenly
across the face of the air cleaner. If the duct is a different
size than the air cleaner cabinet, gradual transitions are
recommended. If the duct turns sharply just before the air
cleaner, turning vanes are recommended.
Applications with Air Conditioning
The air cleaner should be installed upstream from the
evaporator coil. The air cleaner will help keep the coil clean,
reducing maintenance.

68-0137—5

F50F DUCT MOUNTED ELECTRONIC AIR CLEANER
Applications with a Humidifier
An evaporative humidifier can be mounted upstream from
the air cleaner. An atomizing humidifier should be mounted
downstream from the air cleaner, even though hard water
salts will be blown into the living space and deposited as
dust. If an atomizing humidifier must be mounted upstream
from the air cleaner:
1. Mount it as far as possible upstream from the air
cleaner.
2. Install a standard disposable furnace filter between the
humidifier and the air cleaner to trap water droplets
and hard water salts.
3. Frequently clean the air cleaner to prevent a hard
water salt buildup.
NOTE: The volume of water that passes through an
atomizing humidifier can overload the air cleaner,
resulting in hard water salts being deposited as
dust in the living space.
Applications with an Activated Carbon Filter
An activated carbon (charcoal) filter can be used to remove
odors or other gaseous contaminants (not particle-based)
that are not removed by the air cleaner. Locate the carbon
filter:
•Downstream from the air cleaner. This means that dust
from the carbon filter will not be collected by the air
cleaner and will be deposited in the living space.
• Outside the air cleaner cabinet. Some carbon filters are
combustible and contact with high voltage could result in
smoke or fire.
• Where carbon granules cannot fall into the electronic cell.
If necessary, use a disposable furnace filter between the
carbon filter and the electronic cell.
• With proper transitions, if the activated carbon filter
requires a differently sized duct than the air cleaner. Allow
20 degrees expansion per side, per fitting.
NOTE: Honeywell does not offer carbon filters. Refer to an
activated carbon filter manufacturer for sizing and
application.
Applications with Outdoor Air Intake
Return air temperature must be at least 40°F (4°C). Lower
temperatures can cause ionizer wire failure. If outdoor air is
used, warm it upstream from the air cleaner by:
• Making sure the outdoor intake is far enough upstream
from the air cleaner so the return and outdoor air is
thoroughly mixed. Stratified air can dump a stream of very
cold air into one section of the air cleaner.
• Adding baffles upstream from the air cleaner to force
thorough air mixing.
• Installing a Honeywell Home Ventilation System that
transfers up to 80 percent of the heat from the exhaust air
to the incoming outside air. This keeps the incoming air
above 40°F (4°C) and reduces energy usage.
• Installing a preheater if large amounts of outdoor air are
used. The preheater, which could be an electric strip
heater or hot water coil, should be controlled by a
thermostat. Hot water or steam coils should be protected
by a freeze-up control.
Optional W8600F Air Cleaner Monitor
The terminal board is recessed slightly so it or the wires will
not interfere with installation. The entire power supply box
can be unplugged and removed to provide access to the
terminals. The W8600F Air Cleaner Monitor can be mounted
in the living area or in the furnace room. It should be located
in a convenient location to observe the display.
Choose Location
Choose a location that is readily accessible for regular
inspection and cleaning. Allow at least 13 in. (330 mm) in
front of the access door for removing the prefilter and
electronic cell. Allow enough room above the power supply
so it can be serviced without removing pipes, ducts, or other
heating system components.
The air cleaner must be installed where the temperature will
not exceed 40° to 125°F (4° to 52°C).
Choose Mounting Position
WARNING
Heavy Equipment.
Can cause injury or equipment damage.
Do not mount the air cleaner with the access door
facing down. If the access door faces down, the latch
may not hold, and the cell and prefilter can fall
unexpectedly. Also, nothing holds the cell and
prefilter in place when the access door is opened.
The air cleaner can be mounted in any position except with
the access door facing down. Following is a list of air cleaner
mounting positions for a variety of furnace installations.
NOTE: At least 13 in. (330 mm) clearance is required
between the access door and any obstructions for
cell and prefilter maintenance.
— Upflow “Highboy” furnace: Side installation; air cleaner is
mounted vertically where return enters side inlet of
furnace. See Fig. 3A.
— Upflow “Highboy” furnace: Installation beneath furnace
(air cleaner cabinet can easily support weight of furnace
and air conditioner coil). Air cleaner is mounted
horizontally where return enters from below. See Fig.
3B.
— Upflow “Highboy” furnace: Closet installation. Air cleaner
is mounted vertically on furnace between furnace and
louvered return air opening in closet door. See Fig. 3C.
— “Lowboy” furnace: Air cleaner is mounted horizontally in
return plenum just above furnace, opposite of supply
plenum. See Fig. 3D.
—Downflow “Counterflow” furnace: Air cleaner is mounted
horizontally in return duct or plenum just above furnace.
See Fig. 3E.
— High capacity system: Two or more air cleaners can be
used together. See Fig. 3F.
— Electric furnace or heat pump: Single cell air cleaner is
mounted with access door on top. See Fig. 3G.
— Horizontal furnace: Air cleaner is mounted vertically
where return enters. See Fig. 3H.

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
Tr ansitions 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.

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.

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 cell(s)
and prefilter(s).
❑ 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.
❑ 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.
