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 hear a snapping (electrical arcing) sound occasionally
as the air cleaner operates. This is usually caused by a larger
dust particle that causes a high voltage discharge.The snapping
sound means that your air cleaner is working as it should.To hear
the snapping sound, momentarily press the test button near the
botton of the door. Use the test button any time you want to
prove air cleaner operation.
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.
Replace postfilter regularly
A high-efficiency postfilter is sometimes installed in the air cleaner. This filter increases
the efficiency of the air cleaner and should be changed every six months of usage.

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.
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 PREFILTER(S), CELL(S) AND
POSTFILTER(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— twice a year with normal use or more frequently with heavy
use. 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 your Prefilter
1. The quickest and easiest way to clean your prefilter is to use the brush attach-
ment of your vacuum cleaner to vacuum the lint off the dirty side of the prefilter.
Greasy dirt may require soaking the prefilter in a tub or rinsing with the garden
hose. Do not wash the prefilter in the dishwasher or car wash
2. The prefilter should be cleaned every 6 months or more frequently with heavy
use. This will keep the prefilter clean of air choking lint that can make your sys-
tem work harder.
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.
Cleaning your Cells
1. A quick cleaning of the cells can be done by simply wiping down the ionizer
wires with a damp cloth. This will help boost the efficiency of the air cleaner
between full cleaning cycles. Ths quick clean can be done every time the prefil-
ters are cleaned.
2. A full cleaning of the cells will return the air cleaner to its peak efficiency. An easy
way to wash the cells is in a tub of hot, soapy water. Just soak the cells until the
water cools, agitate and rinse. For details on cleaning cells, see below for Wash-
ing the cell(s) in a tub or Washing the cell(s) in your automatic dishwasher.
3. Because the efficiency of the air cleaner remains high even as it loads up with
dirt, a full cleaning of the cells can be put off for yearly maintenance and a quick
cleaning can be done more often. Those wishing to renew to peak efficiency or
with heavier use may want to wash more frequently.
Replacing your Postfilter
1. The postfilter is an optional filter that boosts the efficiency of the air cleaner. Do
not wash the postfilter because that will neutralize the factory applied charge.
2. The postfilter should be replaced every six months to ensure peak performance.

CAUTION
Burn Hazard.
Can cause personal injury.
Allow cell(s) to cool completely in dishwasher and at tend of wash cycle or
wear protective gloves.
Washing the cell(s) in your automatic dishwasher
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 manufacturers do not recom-
mend 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 dish-
washer. 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.
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.
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.
3. Wipe the ionizer wires and contact board on the end of the cell using your thumb
and forefinger with a small, damp cloth.
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 deter-
gent.

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).
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.
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.
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.
4. Next, wash the prefilter(s) the same way. Empty and rinse the wash container.
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.
6. Soak cell(s) in a final clear water rinse for ten minutes.
7. Wipe the ionizer wires and contact board on the end of the cell using your thumb
and forefinger with a small, damp cloth.

69-0756—05 10
Replacing electronic air cleaner components
1. Inspect the cell(s) for broken ionizer wires and bent collector plates. Repair, as
necessary, or call your contractor for service.
2. Slide the prefilter(s) into the upstream prefilter guides.
3. Slide the air cleaner cell(s) in so the air flow arrow points downstream and the
handle(s) face outward.
4. Firmly close the access door.
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, the charged particles stick to the collector plates, having an opposite electric
charge.The precharged postfilter continues to remove small particles from the air. 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 and Drug Administration, and Health and Welfare Canada
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.
