F50F
Duct Mounted Electronic Air Cleaner
INSTALLATION INSTRUCTIONS
APPLICATION
The high efficiency F50F Electronic Air Cleaner is
mounted in the return air duct of a forced air heating,
cooling, or ventilating system. It captures a significant
amount of airborne particles 0.5 microns and larger from
the air circulated through it. All models have an internal
airflow switch to operate the F50F when the system
blower is on.
PLANNING THE INSTALLATION
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.
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 upstream as possible 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 size 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 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
The F50F 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.

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.

Position Cell Key
The electronic cell must always be installed so the ionizer
section is on the upstream side. A factory-installed cell key
on the bottom of the cabinet allows the cell to be inserted
in only one direction. As long as the arrow molded into the
plastic key points in the same direction as the airflow, the
ionizer will always be on the upstream side.
If the position of the key must be reversed, proceed as
follows:
1. Re
move electronic cell.
2. Remove the screw holding the cell key in place.

OPERATION
Large particles (lint, hair) are caught by the prefilter. As the
dirty air passes through the intense high voltage electric
field surrounding the ionizer wires, all particles are given
an electrical charge. The air then moves through the
collector part of the cell where alternate parallel plates are
charged positively and negatively, creating a uniform
electrostatic field. The charged particles are attracted to
and collect on the plates having the opposite electrical
charge. The air leaving the air cleaner has fewer particles.
Each time the air circulates through the F50F, more
particles are removed.
CHECKOUT
Inspect The Installation
Make sure:
• Turning vanes and transitions, as needed, are
properly installed.
• Sheet metal joints between air cleaner and furnace
are sealed.
• All sheet metal connections are complete.
• Original furnace filter has been removed and the blower
compartment cleaned.
• If an atomizing humidifier is installed upstream from the
air cleaner, a disposable furnace filter is installed
between the humidifier and the air cleaner.
• Outside air, if used, is mixed with return air or heated,
as necessary, before it can reach the air cleaner.
• The airflow arrows on the electronic cell point
downstream.
• The prefilter is on the upstream side of the cell.
• The cell handle faces outward.
• The electronic cell and prefilter are clean and dry.
• That W8600F (if included) wiring connections are

Check Air Cleaner Operation
With all components in place, turn on the air cleaner switch
and energize the system blower. Check the following
points of operation:
1. The neon light next to the on-off switch is on. If a
W8600F is part of the installation, also check the
wall panel and make sure ON is indicated. The
W8600F FAULT indicator will come on if there is a
problem with the high voltage power supply.
2. Turn off the system blower. The neon light should go
off after a few seconds. The neon light shows that
the air cleaner is energized and the high voltage
power supply is working properly.
3. Turn on the system blower. With the air cleaner
energized, push the test button. A snapping sound
indicates that the collector voltage is present on the
cell. On air cleaner with a W8600F, the FAULT
indicator will come on when the test button is held
down.
4. With a multispeed blower, repeat steps 1-3 for each
fan speed.
5. If operation is not as described, refer to the Trouble-
shooting and Service section.
