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
air flow 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 compart-
ment 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 transi-
tions 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.

INSTALLATION INSTRUCTIONS
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.
WARNING
Fire or Explosion Hazard.
Can cause property damage, severe injury
or death.
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 different size duct than the air cleaner. Allow
20 degrees expansion per side, per fitting.
NOTE: Honeywell does not offer carbon filters. Consult
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 pro-
tected 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
