PLANNING THE INSTALLATION
Application and Construction
The air cleaner should be installed in the occupied space
return duct opening leading to a central air handling system.
All of the air circulated by the system must pass through the
electronic air cleaner.
The front door of the electronic air cleaner is hinged to
provide access to the internal components. See Fig. 4.
The air cleaner has one or two electronic cell(s) that must be
installed with the ionizer section (side with fine wires) facing
the door.

The cell(s) is held in place by metal hooks and a
quarter-turn latch.
A spring contact provides the electrical connection between
the solid state power supply and the electronic cell(s). An
interlock switch interrupts the line voltage to the power supply
when the door is opened. A rocker-type ON-OFF switch
allows the air cleaner to be turned off manually. An indicator
light that is on shows that the air cleaner is energized and the
power supply is producing high voltage.

In a wall installation, mount the one-cell air cleaner with the
door hinge on the bottom so the air cleaner fits between the
two studs 16 in. (407 mm) on center. The two-cell air cleaner
fits between two studs 24 in. (610 mm) on center when
mounted with the hinge on either side
or
between three 16 in.
studs, with center stud removed, when mounted with hinge on
the bottom.
Do not install either unit with the hinge on the top because the
cell(s) will be awkward to remove.
Determine Duct Design Requirements
The return duct should end at, or slightly behind, the finished
wall surface. Do not use a standard register flange, or the
door may not fit tightly against the wall.
Transitions
Transitions are needed when the duct is a different size than
the air cleaner. Gradual transitions reduce air turbulence and
increase efficiency. The transition should be 20 degrees or
about 4 in. per running ft (100 mm per 300 linear mm) or less
on each side of a transition fitting.

SERVICE
CAUTION
Sharp Edges.
Can cause personal injury.
Handle the cell(s) carefully to avoid cuts from the
sharp metal edges.
Cleaning the Electronic Cell(s) and Prefilter
Clean the electronic cell(s) and prefilter regularly every one to
six months. Variables such as number of occupants, activities
and smoking determine how often cleaning is required. Use
the wash reminder schedule in the literature packet to help
establish and maintain a regular cleaning schedule.
If the air cleaner has the optional W8600F Air Cleaner
Monitor, the SERVICE is activated to indicate that a cell and
prefilter washing is due. The SERVICE indicator does not
come on when the prefilter gets clogged; clean the prefilter
every time the cell(s) are cleaned.
The cell(s) can be washed in most automatic dishwashers, by
soaking in a tub or at a do-it-yourself coin operated car wash.
The prefilter can be vacuumed, brushed, sprayed with a
garden hose. Do not wash the prefilter in the dishwasher or
car wash.
The heating or air conditioning system can be run while the
cell(s) is being washed. Simply turn off the air cleaner switch.

CHECKOUT
Inspect the Installation Before Putting
Electronic Air Cleaner into Operation
Make sure:
• The wiring connections in the power box are properly
made with the proper connectors.
• The metal mesh prefilter is positioned properly.
• The airflow arrows on the cell(s) point away from the
door/grille.
• The electronic cell(s), prefilter and door/grille are clean
and dry.
• The contact is good between electronic cell and the power
supply contacts.
• The W8600F (if used) wiring connections are
properly made.
Check Air Cleaner Operation
With all components in place, turn on the air cleaner switch
and close the door/grille. Energize the system fan and check
that the neon light, visible through the air cleaner door/grille,
lights. This indicates that the air cleaner is energized and the
power supply is producing high voltage. If the light does not
CAUTION
Burn Hazard.
Can cause personal injury.
Allow the cell(s) to cool in the dishwasher at the end
of the wash cycle or wear protective gloves to avoid
burns. Hot water can accumulate in the tubes that
support the collector plates. Tip the cell(s) so these
tubes can drain.
IMPORTANT
• Check your dishwasher owner manual. Some
manufacturers do not recommend washing
electronic cells 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 or bending the cell
plates when placing them in the dishwasher. If
bent, arcing will result.
• Very dirty cells, especially from tobacco or
cooking smoke, can discolor the plastic parts and
lining of the dishwasher. The discoloration is not
harmful. To minimize it, wash the cells more
frequently or try a different brand of detergent.
• DO NOT ALLOW THE DISHWASHER TO RUN
THROUGH THE DRY CYCLE. This will bake on
any contaminants not removed during the wash
cycle and reduce 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, if provided on the dishwasher.
HINT: Lay a few large water glasses between the
spikes
on the lower rack, and rest the cells on
them so the
aluminum collector blades.
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 may be
trapped in the tubes that support the collector plates.
Tip the cell(s) so these tubes can drain.
3. Wipe the ionizer wires and contact board on the end of
the cell with a clean cloth.
4. Inspect the dishwasher. You can 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.
5. Inspect the cell(s) for bent plates; bend back to normal
to prevent arcing.
spikes
do not damage the
Soaking
CAUTION
Hazardous Chemical.
Can cause personal injury.
Do not splash the detergent solution in eyes. Wear
rubber gloves to avoid prolonged detergent 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).
Car Wash
Use the hand sprayer at a coin-operated car wash to wash
the cell(s). Hold the nozzle at least 2 ft (0.6m) 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). Rinse until
the water draining from the cell(s) no longer feels slippery.
Reinstalling Cell(s) and Prefilter
1. Inspect the cell(s) for broken ionizer wires and bent
collector plates. Repair as necessary.
2. Replace the cell(s) properly. The electrical contact
board must face the power supply contacts. The airflow
arrows on the cell(s) must point into the air duct. Secure
with the latch.
3. Reinstall the prefilter. Turn on the air cleaner.
4. Close the door/grille and fasten it with the two door
latches.
5. Turn on the system fan. If the cell(s) and prefilter are
wet, you may hear arcing (snapping). If the arcing is
annoying, simply turn off the air cleaner for two to three
hours, or until cells are dry.
Cleaning the Door/Grille
The door/grille may require washing periodically, though not
as frequently as the electronic cell(s) and prefilter. When it
appears dirty, it can be vacuumed using the brush attachment
on your vacuum cleaner, or disassembled and cleaned by
agitating in a solution of mild detergent in warm water.
Replacing Ionizer Wire
Broken or bent ionizer wires can cause a short to ground,
often resulting in visible arcing or sparking. On air cleaners
with a W8600F, any short in the ionizer or collector section
activates the FAULT indicator on the W8600F wall panel. Do
not use the cell until the pieces of broken wire are removed. It
can be used temporarily with one wire missing, but replace
the wire as soon as possible. See Parts List section for order
number.
1. Use a container that is large enough, such as a laundry
tub or trash container, to hold one or both cells. Sharp
corners on the cell(s) can scratch the surfaces.
2. Dissolve about 3/4 cup of automatic dishwashing
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 to soak for 15 to 20 minutes.
Agitate up and down a few times, and then remove.
4. Next, wash the prefilter the same way. Empty and rinse
the wash container.
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
water draining from the cell(s) and prefilter no longer
feels slippery.
6. Wipe the ionizer wires and contact board on the end of
the cell with a clean cloth.
Replacement wires are cut to length with eyelets on both
ends for easy installation. To install:
1. Hook the eyelet on one end of the wire over the spring
connector on one end of the cell. See Fig. 17. Be
careful to avoid damaging the spring connector or other
parts of the cell.
2. Hold the opposite eyelet with a needlenose pliers and
stretch the wire the length of the cell. Depress the
opposite spring connector and hook the eyelet over it.

Tools and Equipment
Troubleshooting the electronic air cleaner requires only a
couple of tools:
• Needlenose pliers (for stringing ionizer wires).
• Ohmmeter with 25 kVdc probe (Fluke model 80K -40 H.V.
or equivalent). See Fig. 21.
Troubleshooting Procedure
CAUTION
Electric Shock Hazard.
Can cause personal injury.
The Electronic Air Cleaner troubleshooting procedures,
Fig. 18 and 19, show how to quickly isolate a problem in the
air cleaner. Although a meter is needed for some steps, the
primary diagnostic tools are the neon light and the FAULT
indicator (on air cleaners with W8600F).
The solid state power supply assembly provided in this air
cleaner has no field-serviceable components. If
troubleshooting indicates a power supply assembly problem,
replace the entire power supply assembly. See Parts List
section for order number.
Neon Light
The neon light is visible through the door. It is powered by the
high voltage portion of the power supply. When on, it indicates
that the air cleaner is powered, the power supply is working
properly and air is flowing in the system. The neon light will
not be on if air is not flowing through the air cleaner.
FAULT Indicator (Air Cleaners with W8600F)
The FAULT indicator is on the W8600F. It activates to indicate
any of the following problems: excessive dirt loading, partial
shorting of the collector, continuous ionizer or collector arcing,
power supply failure, excessive ionizer current, or any
condition causing a major reduction in high voltage.

Fig. 21. Use an ohmmeter to check electronic cell(s)
for short circuits.
IMPORTANT
Only a trained service technician should perform the
following procedure.
The electronic air cleaner generates a small amount of ozone
in normal operation. During the first week or two of operation,
the amount can be higher because of sharp edges on some
of the new high voltage metal parts. Normal use dulls these
edges in a short time.
The average person can detect the odor of ozone in
concentrations as low as 0.003 to 0.010 parts per million
(ppm). The electronic air cleaner contributes 0.005 to
0.010 ppm of ozone to the indoor air. 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.
68-0074—915
F52F RETURN GRILLE ELECTRONIC AIR CLEANER
However, if desired, the ozone generated by the air cleaner
can be reduced by moving J5 on the power supply. This
reduces ozone production about 20 to 25 percent and
reduces efficiency about 7 to 10 percent, depending on actual
airflow delivered by the furnace blower.
To Reduce Ozone Odor
1. Open the air cleaner door, turn off the power to the air
cleaner, and remove the cell(s).
2. Remove the power supply enclosure.
3. Find J5 and move it. See Fig. 22.
4. Replace the power supply enclosure.
5. Replace the cell(s), turn on the power, and close the air
cleaner door.
