OPERATING YOUR ELECTRONIC AIR CLEANER
Turn the On-Off switch on the power box to On.
NOTE: Set the switch to 1 for On and set the switch to O for
Off.
The air cleaner now operates whenever your furnace/air
conditioning system fan operates. For maximum air cleaning
benefit and cleaner air conditioner coils, leave the air cleaner
switch turned on at all times and the thermostat fan switch set
to On. Of course, continuous fan operation adds to your electric
bill each month. Check your equipment for the amount of
electricity needed to run your System fan.
When the fan and air cleaner come on, the neon indicator lights.
You may occasionally hear a snapping (electrical arcing) sound
as the air cleaner operates. The source is larger dust particles
that cause a high voltage discharge.The snapping sound
means that your air cleaner is working as it should.
The switch remains in the On position to keep the air cleaner
running.
When the fan and air cleaner stops, the neon light goes off.The
air cleaner is off until the heating or air conditioning and fan start
again.
If you do not want the air cleaner to run, set the On-Off switch to
Off to turn off the air cleaner. Your furnace and air conditioner
continue to operate normally, but without the added benefit of
air cleaning. Normally, this switch should be turn to On at all
times.

GETTING THE MOST FROM YOUR ELECTRONIC AIR
CLEANER
Run the
electronic air
cleaner as
much as
possible
For greatest efficiency, the air cleaner should run all the time. To
do this, set the Fan switch on your thermostat to On, and make
sure the air cleaner is turned on. The fan and air cleaner run
even when the furnace or air conditioner is off.
NOTE: A manual fan switch may be built into the furnace or
furnace fan controller.
The air cleaner uses less power than a 40 watt light bulb (two-
cell model—33 watts; single cell model—22 watts). Many
believe that the added cost is more than offset by the added
benefits of full-time air cleaning and full-time air circulation. And
you may feel that the room temperature stays more even when
the fan is always on.
Even if your thermostat does not have a Fan On position, you
can obtain maximum available air cleaning benefit by making
sure the air cleaner is always turn to On so it operates
whenever the furnace or air conditioner is on.
Keep the
cell(s) and
prefilter(s)
clean
Although the air cleaner is designed to be efficient over a wide
range of cell dirt loading conditions, regular cleaning is your
best assurance of consistent performance. Also, a very dirty
prefilter and cell reduces air flow and, in turn, this reduces the
efficiency of the furnace or air conditioner. The cell wash
reminder schedule or the optional W8600 Air Cleaner Indicator
should be used to maintain a regular wash schedule.
If you have a
humidifier
All Honeywell whole house humidifiers can be used in a system
with the Honeywell Electronic Air Cleaner without any additional
filters or system modification.
If your system includes an atomizing humidifier, you may want
to install a standard furnace filter between the humidifier and
the air cleaner.This filter would keep the humidifier spray
mineral deposits from collecting on the air cleaner.This filter
should be checked regularly and changed when it shows signs
of mineral or dirt buildup. If you do not install a filter, you will
probably need to wash the cell(s) and prefilter(s) more often to
remove the mineral buildup.

F50F AND F300E ELECTRONIC AIR CLEANERS
5 69-0756-3
If an ultrasonic room humidifier is used often, especially if filled
with tap (undistilled) water, the cell(s) and prefilter(s) require
more frequent washing. A white residue accumulates on the
cell(s) from the minerals in the water. This residue may also
contribute to "white dust.” See About lint or “white dust” section
for more information.

CLEANING THE PREFILTER(S) AND CELL(S)
CAUTION
Sharp edges.
Can cause personal injury.
Carefully handle cell(s) or wear protective gloves to
avoid cuts from sharp metal edges.
Setting a
regular
cleaning
schedule
To ensure optimum performance from the air cleaner, the
prefilter(s) and cell(s) must be cleaned regularly—the
prefilter(s) should be cleaned every one to six months and the
cell(s) every six to twelve months. Washing frequency varies,
depending on the number of family members, pets, activities
(such as cooking or woodshop) and smoking habits. Use the
wash reminder schedule below to help establish and maintain a
regular cleaning schedule. Mount the wash reminder schedule
in a convenient location.
NOTE: You may let the heating or air conditioning system
operate normally while the cell(s) are being washed.
Simply turn off the air cleaner switch.

Cleaning the
prefilter(s)
Vacuum the prefilter with a brush attachment, rinse it with a
hose, or soak it in a tub. Do not wash the prefilter(s) in the
dishwasher or car wash.
CAUTION
Burn Hazard.
Can cause personal injury.
Washing the
cell(s) in your
automatic
dishwasher
Allow the cell(s) to cool completely in the dishwasher at the end
of the wash cycle or wear protective gloves to avoid burns. Hot
water can accumulate in the tubes supporting the collector
plates.Tip the cell(s) so these tubes can drain.
IMPORTANT
• Check your dishwasher Owner’s manual. Some manu-
facturers do not recommend washing electronic cell(s)
in their dishwashers.
• If the dishwasher has upper and lower arms, position
the cell(s) carefully to allow good water circulation.
• Be careful to avoid damaging the cell(s) when placing
them in the dishwasher. Broken ionizer wires or bent
collector plates are not covered under the Warranty.
• Very dirty cell(s), especially from tobacco or cooking
smoke, can discolor the plastic parts and the lining of
some dishwashers.This discoloration is not harmful.
To minimize it, wash the cell(s) more frequently or try a
different brand of detergent.
•Do NOT allow the dishwasher to run through the
dry cycle. This bakes on any contaminants not
removed during the wash cycle and reduces air
cleaner efficiency.
Step 1 Put the cell(s) on the lower rack of the dishwasher with the
airflow arrow pointing up. It may be necessary to remove the
upper rack. Do not block water flow to the upper arm.
HINT: Lay a few large water glasses between the spikes on the
lower rack, and rest the cell(s) on them so the spikes do not
damage the aluminum collector blades.

F50F AND F300E ELECTRONIC AIR CLEANERS
69-0756-3 8
Step 2 Using your regular dishwashing detergent, allow the
dishwasher to run through the complete wash and rinse cycle.
Do not use the dry cycle.To avoid burns, let the cell(s) cool
completely before removing, or wear protective gloves when
removing the cell(s). Remember that water may be trapped
inside the cell(s) plates. Tip the cell(s) so these tubes can drain.
Step 3 Wipe the ionizer wires and contact board on the end of the cell
using your thumb and forefinger with a small, damp cloth.
Step 4 Inspect the dishwasher. You may want to rerun the wash and/or
rinse cycle with the dishwasher empty if you see dirt or residue
from washing the cell(s). If dirt or residue seems excessive,
wash the cell(s) more often or try a different detergent.
CAUTION
Hazardous Chemical.
Can cause personal injury.
Do not splash detergent solution in eyes.
Washing the
cell(s) in a tub
• Wear rubber gloves to avoid prolonged detergent contact
with your skin.
• Keep detergent and solution out of reach
of children.
NOTE: Always wash the cell(s) first, then the prefilter(s), to
keep heavy prefilter lint from getting caught in the
cell(s).
Step 1 Use a large enough container, such as a laundry tub or trash
container, to hold one or both cell(s).
NOTE: Sharp corners on the cell(s) can scratch the surface of
a bathtub.
Step 2 Dissolve about three-fourth cup of automatic dishwasher
detergent per cell in enough hot water to cover the cell(s). If the
detergent does not dissolve readily, or forms a scum on the
water, try another brand, or use softened water.

F50F AND F300E ELECTRONIC AIR CLEANERS
9 69-0756-3
Step 3 After the detergent has completely dissolved, place the cell(s)
in the container and allow to soak for 15 to 20 minutes or until
water cools. Agitate them up and down a few times and
remove. Repeat steps 2 and 3, if necessary, for very dirty cells.
Step 4 Next, wash the prefilter(s) the same way. Empty and rinse the
wash container.
Step 5 Rinse the cell(s) with a hard spray of very hot water; rinse the
tub clean, then fill the tub with clean hot water and soak for 5 to
15 minutes. Rinse until the water draining from the cell(s) and
prefilter(s) no longer feels slippery.
Step 6 Soak cell(s) in a final clear water rinse for ten minutes.
Step 7 Wipe the ionizer wires and contact board on the end of the cell
using your thumb and forefinger with a small, damp cloth.

Replacing
electronic air
cleaner
components
Step 1 Inspect the cell(s) for broken ionizer wires and bent collector
plates. Repair, as necessary, or call your contractor for service.
Step 2 Slide the prefilter(s) into the upstream prefilter guides.
Step 3 Slide the air cleaner cell(s) in so the air flow arrow points
downstream and the handle(s) face outward.
Step 4 Firmly close the access door.
Step 5 Turn on the air cleaner. If the cell(s) and prefilter(s) are wet, the
neon light may not come on and you may hear arcing. If the
arcing is annoying, simply turn the air cleaner off for two to
three hours or until the cell(s) are dry.

HOW ELECTRONIC AIR CLEANING WORKS
A word about
particle size
The particles removed by the electronic air cleaner tend to be
very small—less than ten microns. But what is a ten-micron
particle? The eye of an average size sewing needle is about
750 microns across, and the dot in the i in the word micron is
about 400 microns. Generally, particles smaller than ten
microns can be seen only with a microscope, except in very
large concentrations, such as a puff of smoke. Your electronic
air cleaner can remove even smaller particles that can be seen
only with an electron microscope.
Although particles one micron and smaller make up only about
20 percent of the total weight of particles in unfiltered air, they
account for over 99 percent of the numbers of particles.
Because they are so tiny, these particles tend to remain
suspended in the air unless they collide with a solid surface.
Then they attach by molecular adhesion and stick like glue,
staining walls and furniture and coating your air conditioning
coils. And of course, some of these particles can cause allergic
reactions or simply make the environment less pleasant.
How the
electronic air
cleaner works
First, large particles (lint, hair) are caught by the prefilter(s).
Then, as the dirty air passes through the intense high voltage
electric field surrounding the ionizer wires, all particles, even the
smallest particles down to 0.3 micron are given an electric
charge.The air then passes into the collector where the
alternate parallel plates are charged positive and negative,
creating a uniform electrostatic field. Since opposites attract,

F50F AND F300E ELECTRONIC AIR CLEANERS

the charged particles stick to the collector plates, having an
opposite electric charge.The air leaving the air cleaner contains
very few particles.
Each time the air circulates through the heating/air conditioning
system and air cleaner, more particles are removed. These
particles are generated by normal household activities and also
enter the house from outside. That is the reason we
recommend that you use the air cleaner as much as possible.
Electronic air
cleaner vs
standard
furnace filter
The regular furnace filter collects mainly large, visible particles
that reach the filter. Its main purpose is to protect the furnace
and air conditioner blower. The electronic air cleaner collects
these large particles plus many of the smaller, mostly invisible
particles. Its purpose is to reduce indoor air pollution as well as
to protect the blower, air conditioning coils and heat exchanger.
Ozone and the
electronic air
cleaner
Electronic air cleaners generate a very small amount of ozone,
about 0.005 to 0.010 parts per million (ppm). The amount is
highest when the air cleaner is new.
The average person can detect the odor of ozone in
concentrations as low as 0.003 to 0.010 ppm. The U.S. Food

recommend that indoor ozone concentration should not exceed
0.050 ppm. As a comparison, the outdoor ozone level in major
cities is sometimes higher than 0.100 ppm.
If desired, the ozone generated by the air cleaner can be
reduced by asking your dealer to:
• Install an activated carbon filter downstream of the air
cleaner, or
• Adjust the air cleaner power supply to reduce ozone
production.This adjustment reduces ozone production about
20-25 percent, but also reduces air cleaning efficiency about
seven to ten percent.
About lint or
“white dust"
White dust is made up of particles that settle out of the air
before they get to the return air duct. You can help prevent this
white dust from settling by running your fan constantly and:
• Be sure the return registers are not blocked with furniture.
• Be sure the discharge ducts are clean (best done before
installing the air cleaner).
• Be sure your clothes dryer is vented to the outside and is not
plugged.
• If you have new rugs or drapes or new woolen blankets, be
aware that the lint from these items will reduce with age.
• In new or remodeled homes, plaster dust or paint pigment
may contribute to white dust, but will reduce with time.
• Use of a humidifier may contribute to white dust, especially if
filled with undistilled water.
