THE SOLID STATE PERFORMANCE INDICATOR
This air cleaner is equipped with a
special solid state circuit that operates
the optional W8600E Solid State
Performance Indicator (see photo).
The W8600E Indicator is designed to be
mounted next to your thermostat, and to
monitor the air cleaner performance.
If you have ordered the W8600E
Indicator, you will notice three light-
emitting diodes (LEDs) on the W8600E
labeled ON, WASH and CHECK.
• During normal air cleaner opera-
tion, the ON LED is lit (whenever
the system fan is on).
• If excessive dirt has accumulated on the air cleaner’s cell(s), the
WASH LED will light to alert you that a cell and prefilter wash is
past due.
• Extreme dirt loading (beyond that required to activate the WASH
LED), electronic malfunction, or other equipment problems will
cause the CHECK LED to light.

OPERATINGYOUR ELECTRONIC AIR CLEANER
Set the ON-OFF switch to ON.The air
cleaner will now operate whenever
your furnace/air conditioning system
fan operates. For maximum air
cleaning benefit and cleaner air
conditioner coils, leave the air cleaner
switch on at all times and the fan
switch on your thermostat on. Of
course, continuous fan operation will
add a small amount to your electric bill
each month.
When the fan comes on, the neon light
located near the ON-OFF switch will
light, indicating that the air cleaner is
functioning.
ONE-CELL MODEL SHOWN.
If your air cleaner is equipped with a
wall-mounted W8600E Solid State
Performance Indicator (see page 2),
the ON LED will be on
whenever the
air cleaner is in operation
. Of course,
the system fan will also be running.
You may hear a snapping electrical
arcing sound occasionally as the air
cleaner operates.This is usually
caused by a larger dust particle
causing a high voltage discharge.The
snapping sound means that your air
cleaner is working as it should.

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 will still operate
normally, but without the added benefit
of air cleaning. Normally, this switch
should be ON at all times.
When the fan stops, the neon light
goes out, as does the ON LED on the
Solid State Performance Indicator.The
air cleaner is off until the heating or air
conditioning and fan start again.

GETTINGTHE MOST FROMYOUR AIR CLEANER
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 switched on.The fan and air cleaner
will run even when the furnace or air conditioner
is off.Note: A manual fan switch may be built
into the furnace fan controller.
The air cleaner itself uses less power than a
40 watt light bulb (two-cell model—33 watts;
single-cell model—22 watts).You will also have
the cost of running the system fan to consider.
Generally the added cost is more than offset by
the added benefits of full time air cleaning and
improved air circulation. Some people feel that
room temperatures stay 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 switched on so it operates whenever
the furnace or air conditioner is on.
Although the air cleaner is designed to be
efficient over a wide range of cell loading
conditions, regular cleaning is your best
assurance of consistent performance. Also, a
very dirty cell and prefilter reduces air flow and,
in turn, this reduces the efficiency of the furnace
or air conditioner.

CLEANINGTHE CELL(S) AND PREFILTER
To ensure optimum performance from the air
cleaner, the cell(s) and prefilter must be cleaned
regularly—every one to six months.Washing
frequency will vary depending on the number of
family members, pets, activities (such as cooking,
woodworking, etc.) and smoking habits. Use the
wash reminder schedule included in the literature
package to help establish and maintain a regular
cleaning schedule.
Setting a
regular cleaning
schedule
If your air cleaner has a W8600E Indicator (shown on page 2), the
WASH LED will light to remind you that a cell and prefilter washing is
past due.When the WASH LED comes on, it means that the cell(s) are
loaded with dirt to the point that air cleaning efficiency is diminished.You
should plan to wash the cell(s) and prefilter as soon as possible. By
using the wash reminder schedule, a washing schedule can be
established that keeps the cell(s) clean enough so the WASH LED does
not come on.
If you find that the WASH LED is coming on more frequently than the
schedule that was established on the wash reminder schedule, you may
have a buildup of residue on the ionizer wires.If the collector plates on
the cell(s) look clean, you can try wiping the ionizer wires with a clean
cloth instead of washing the entire cell.
You can also consider whether some activity in your home has changed,
causing the cell(s) to become dirty faster. Have the windows been open
more often? Has someone been smoking more often? Has someone
taken up woodworking?
NOTE: You can let the heating or air conditioning system operate
normally while the cell(s) is being washed. Simply turn off the
air cleaner switch.

IMPORTANT
• Check your dishwasher owner's manual.Some manufacturers 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.
• Use care 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, if provided on your dishwasher. Hint: Lay a
few large water tumblers between the spikes on the lower rack and rest
the cell(s) on them so the spikes do not damage the aluminum collector
blades.
STEP 2
Using the detergent that works best for normal dishwashing, 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 can be trapped inside the cell(s) tubes.Tip the
cell(s) to drain.
STEP 3
Wipe the ionizer wires and contact board on the end of the cell with a
clean cloth.
STEP 4
Inspect the dishwasher.You may wish 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 the detergent solution in eyes.
Wear rubber gloves to avoid prolonged de-
tergent contact with skin.
• Keep detergent and solution out of reach of
children.
NOTE: Always wash the cell(s) first, then the
prefilter to keep heavy lint from getting caught in
the cell(s).
STEP 1
Use a container, such as a laundry tub or trash
container, that is large enough to hold one or
both cell(s).
NOTE: Sharp corners on the cell(s) can scratch
the surface of a bath tub.
STEP 2
Dissolve about 3/4 cup of automatic dish-
washing 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.
STEP 3
After the detergent has completely dissolved,
place the cell(s) in the container and let them
soak for 15 to 20 minutes. Agitate them up and
down a few times, and remove.
STEP 4
Next, wash the prefilter the same way. Empty
and rinse the wash container.

STEP 5
Rinse the cell(s) and prefilter 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 no longer feels slippery.
STEP 6
Wipe the ionizer wires and contact board on the
end of the cell with a clean cloth.
Use the hand sprayer at a coin-operated do-it-
yourself car wash to wash the cell(s) and
prefilter. Hold the nozzle at least two feet away
from the unit to avoid damage from the high
pressure stream of water. Follow the same
sequence of wash and rinse as recommended
for cars; however, do not wax the cell(s) or the
prefilter. Be sure to rinse until the water draining
from the cell(s) and prefilter no longer feels
slippery.
Just as with a conventional return air grille, lint
and dust will collect on the grille and door of
your electronic air cleaner.This can be removed
during normal house cleaning by dusting or by
using the brush attachment on your vacuum
cleaner. If the door becomes stained, so that it
cannot be cleaned by dusting, the door can be
removed and soaked in a tub, or wiped clean
using a mild spray cleaner.
STEP 1
Inspect the cell(s) for broken ionizer wires and
bent collector plates. Repair as necessary or
take to a Honeywell authorized air cleaner
repair station.

It is very important that the electronic cell(s) be
properly replaced:
a. Electrical contact board
must face the power
supply contacts.
b. Airflow arrows on the cell(s) must point into
the air duct.
c. Hook the cell(s) on the metal hooks and
rotate into the air cleaner.
d. Rotate the cell latch to secure the cell(s).

Turn on system fan. If the cell(s) and prefilter
are wet, the neon light may not come on and
you may hear arcing. If the arcing is annoying,
simply turn off the air cleaner for 2 to 3 hours or
until the cell(s) are dry.
If your air cleaner has a Solid State
Performance Indicator, the CHECK LED may
come on if you install wet cell(s) and prefilter.
Again, if the neon light or the CHECK LED
annoys you, simply turn off the air cleaner for 2
to 3 hours or until the cell(s) and prefilter are

HOW ELECTRONIC AIR CLEANINGWORKS
The particles removed by the electronic air
cleaner tend to be very small—less than ten
microns. But what is a 10 micron particle? The
eye of an average sized sewing needle has a
diameter of about 750 microns, 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 more than 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.

First, large particles (lint, hair) are caught by the
prefilter.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 0.5 microns, 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.The
charged particles stick to the collector plates.
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 why
we recommend that you use the air cleaner as
much as possible.

The air cleaner
vs. the 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 and to protect the
blower, air conditioning coils and heat
exchanger.

Air ionizers have been marketed with claims
about purifying the air and promising medical
benefits. It should be noted that supporting
tests, if available, are controversial and
incomplete.
Air ionizers can generate a bit of ozone, and
can generate some ions (bits of material
carrying some electricity).This is what your
electronic air cleaner's ionizer does, but with
greater intensity; however, air ionizers do not
have good collectors, if any.With air ionizers,
the contamination is emitted all over walls and
floors, requiring frequent cleaning of the entire
building to remove the effects of collected
contamination. By comparison, an electronic air
cleaner deposits contamination on the cell(s)
and prefilter for easy cleaning.
Another benefit of an electronic air cleaner is
that it reduces excessive positive or negative
ions in the air, while an air ionizer generates
some ions.
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 as high as 0.100 ppm.
