Applications with Air Conditioning  
PLANNING THE INSTALLATION  
The air cleaner should be installed upstream of the  
evaporator coil. The air cleaner helps keep the coil clean,  
reducing maintenance. Also, if the air cleaner is downstream,  
the high relative humidity of the cooled air leaving the  
evaporator coil can cause water condensation on the cells,  
reducing air cleaner efficiency.  
Application  
The F50E is used in a forced air heating, cooling, or  
ventilating system. It operates when the system blower is on.  
Models with internal solid state air flow switch require only  
line voltage connection. Models without the air flow switch can  
be energized through the fan switch, a dpdt fan relay or an air  
flow switch such as the S688 Sail Switch. Unless the F50E  
with solid state air flow switch is used, an isolating fan relay or  
air flow switch is required if the system has a multispeed or  
modulating blower motor.  
Applications with a Humidifier  
An evaporative humidifier can be mounted upstream of the air  
cleaner. An atomizing humidifier should be mounted  
downstream of 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 of the air  
cleaner:  
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 compartment so the  
air cleaner can help keep the blower motor and evaporator  
coils clean. Do not mount in the discharge air duct.  
1. Mount it as far as possible upstream of 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. Clean the air cleaner frequently to prevent a hard water  
salt buildup.  
4. Note that 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.  
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 transitions are  
recommended. If the duct turns sharply just before the air  
cleaner, turning vanes are recommended.

F50E DUCT MOUNTED ELECTRONIC AIR CLEANER  
Applications with an Activated Carbon Filter  
If desired, an activated carbon (charcoal) filter can be used to  
remove odors or other gaseous contaminants (not particle-  
based), which are not removed by the air cleaner. Locate the  
carbon filter:  
Downstream from the air cleaner. This means, of course,  
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. 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(s). Use a disposable furnace filter if necessary  
between the carbon filter and the electronic cell(s).  
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.  
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 ahead of the air cleaner by:  
M6028A  
Fig. 3. Highboy furnace, side installation,  
air cleaner is mounted vertically where  
return enters side inlet of furnace.  
Making sure the outdoor intake is far enough ahead of 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 ahead of 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 protected  
by a freeze-up control.  
Choose Location  
Choose a location that is readily accessible for regular  
inspection and cleaning. Allow at least 13 in. (330 mm) in front  
of the access door for removing the prefilters and electronic  
cells. Allow enough room above the power supply so the  
power supply can be serviced without removing pipes, ducts,  
or other heating system components.  
The air cleaner must be installed where the temperature will  
not exceed the ratings in the SPECIFICATIONS section.  
Choose Mounting Position  
WARNING

Heavy Equipment.  
Can cause injury or equipment damage.  
If the access door faces down, the latch may not hold,  
and the cells and prefilters can fall unexpectedly. Also,  
nothing holds the cells and prefilters in place once the  
access door is opened.

Transitions  
Transitions are needed when the duct is a different size than  
the air cleaner cabinet. Gradual transitions reduce air  
turbulence and increase efficiency. Limit expansion to  
20 degrees (about 4 in. per running foot [100 mm per 300  
linear mm]) on each side of a transition fitting. See Fig. 11.

In a multispeed blower application, isolate the air  
cleaner with a dpdt fan relay or sail switch. The air  
cleaner overheats and burns out if it is connected in  
parallel with one winding of a multispeed fan motor,  
and a different winding is powered during a  
thermostat call for cooling.

Note power humidifier connections.  
Wire the air cleaner to run only when the system  
blower is running.  
1. If the system blower is driven by a single-speed, single-  
phase motor, wire the air cleaner into the fan circuit.  
See Fig. 24.  
2. If the system blower is driven by a 3-phase, variable  
speed or a 2-speed motor, the air cleaner must be  
isolated from the blower motor. Use a sail switch  
mounted in the return air duct (see Fig. 25), a dpdt fan  
relay (see Fig. 26), or furnace manufacturer supplied  
terminals. Connecting the air cleaner in parallel with  
one speed of a multispeed motor can create an auto-  
transformer effect. If connected with the high speed,  
voltage supplied to the air cleaner at low speed is too  
low, and the air cleaner may not operate at all. If con-  
nected with the low speed, voltage to the air cleaner at  
high speed is too high and the air cleaner will burn out.  
Connect Ductwork  
Connect the vertical duct section to the elbow. If the  
vertical drop of the duct is less than 7 in. (178 mm) from  
the side of the furnace, shorten the horizontal trunk or  
attach an offset fitting to the elbow.  
When ductwork is properly aligned, connect vertical duct  
to horizontal trunk. See Fig. 25.  
Seal Joints

Seal all joints in the return air system between the air  
cleaner and the furnace to prevent dust from entering the  
clean airstream.  
Disable Unused Prefilter Guide

Attach Cell Handles  
The cell handles are included in the packet of literature.  
They must be installed on the end of the cells that will be  
closest to the access door. To install:  
1. Orient the cells as they will be when installed. The red  
contact board must be up and the airflow arrow  
stamped into the cell must point downstream.  
2. Hold the handle sideways and insert the solid tab on  
the back of the handle into the slot in the cell. Turn the  
handle 90 degrees clockwise to align the divided tab  
with the square hole. See Fig. 28.  
ELECTRONIC AIR CLEANER  
3. Insert the divided tab into the square hole.  
4. Fold up the wedge and insert into the divided tab to lock  
the handle in place. When necessary, press with a blunt  
instrument like the end of a pliers.

The electronic cells must always be installed so the ionizer  
section is on the upstream side. A factory-installed cell key  
on the bottom of the cabinet allows the cells to be inserted  
in only one direction. As long as the arrow molded into the  
plastic key points the same direction as the airflow, the  
ionizer is always on the upstream side.

If the position of the key must be reversed, proceed as  
follows:  
1. Remove electronic cells.  
2. Loosen the screw holding the cell key in place. See  
Fig. 27.  
3. Turn the key around and place it over the opposite  
holes. The tab on the bottom fits into the larger hole,  
and the screw fits into the smaller hole. Make sure the  
arrow on the key points in the direction of air flow  
(downstream).  
Reassemble Air Cleaner  
Insert the electronic cells with the red contact board up  
and the airflow arrow pointing downstream. If the cells do  
not slide easily into the cabinet, check the orientation of  
the cell key.  
Insert the prefilters on the upstream side of the cabinet in  
the guides provided.  
Replace the access door. Insert the tab on the bottom of  
the door into the slot in the cabinet, then swing closed and  
press into place. See Fig. 29. The door must be firmly in  
place or the air cleaner will not operate.  
4. Tighten the screw.  
5. Insert the electronic cells. The ionizer section is now on  
the air-entering (upstream) side of the cabinet.  
If the cell washing schedule on the power box is not

F50E DUCT MOUNTED ELECTRONIC AIR CLEANER  
Check Air Cleaner Operation  
With all components in place, turn on the air cleaner switch  
and energize the system blower. Check the following points of  
operation:  
1. The neon light in the on-off switch is on. If a W8600E is  
part of the installation, also check the wall panel and  
make sure the ON LED is lit.  
2. Turn off the system blower. The neon light should go off.  
The neon light comes on to show that the air cleaner is  
energized and the high voltage power supply is working  
properly. If W8600E is used with air cleaner that has air  
flow switch, the neon light shows only that the air  
cleaner is energized. The CHECK LED will come on if  
there is a problem with the high voltage power supply.  
3. Turn the system blower back on. With the air cleaner  
energized, push the test button. A snapping sound  
indicates that collector voltage is present on the cells.  
On air cleaner with a W8600E, the CHECK LED will  
come on.  
4. With a multispeed blower, repeat steps 1 through 3 for  
each fan speed.  
5. With a meter, check the ionizer voltage between P3 (red  
lead) and ground, and the collector voltage between P4  
(black lead) and ground. The correct voltages are  
printed on the label inside the access door.  
6. If operation is not as described, refer to the Electrical  
Troubleshooting section.  
Fig. 29. Close access door to complete  
air cleaner installation.  
SERVICE  
CAUTION  
CHECKOUT  
Sharp Edges.  
Inspect the Installation  
Can cause personal injury.  
Handle the cells carefully or wear protective gloves to  
avoid cuts from the sharp metal edges.  
Make sure:  
Turning vanes and transitions, as needed, are  
properly installed.  
Sheet metal joints between air cleaner and furnace  
are sealed.  
Cleaning the Cells and Prefilters  
When enough lint accumulates to block the air flow, the  
prefilter can quickly become clogged. Inspect the prefilters  
monthly, and clean if necessary to prevent possible lint  
clogging. The cell washing can also be done at this time, or  
can wait until next inspection if cells still look clean.  
Regardless, clean the cells and prefilters regularly—every  
one to six months. Variables such as number of family  
members, pets, activities and whether anyone smokes  
indoors determine how often cleaning is required. Use the  
wash reminder schedule on top of the air cleaner to record  
dates of cell washings, to help establish and to maintain a  
regular cleaning schedule.  
All sheet metal connections are complete.  
Original furnace filter was removed and the blower  
compartment cleaned.  
If an atomizing humidifier is installed upstream of the air  
cleaner, that a disposable furnace filter is installed  
between the humidifier and the air cleaner.  
If the furnace has a multispeed or modulating blower (and  
an air cleaner without solid state air flow switch is used),  
that an interlock (sail switch or dpdt relay) provides  
electrical isolation.  
Outside air, if used, is mixed with return air or heated as  
necessary before it can reach the air cleaner.  
The high voltage contacts on the cell touch the spring  
contacts in the contact tray.  
The airflow arrows on the electronic cells point downstream.  
The prefilters are on the upstream side of the cells.  
The cell handles face outward.  
If the air cleaner has the optional W8600E Solid State  
Performance Indicator, the WASH LED will come on to remind  
you that a cell and prefilter washing is past due. If the WASH  
LED seems to light soon after a cell washing, thorough wiping  
of the ionizer wires may be all that is needed. Cells should be  
washed and ionizer wires wiped frequently enough to prevent  
WASH LED from coming on. The WASH LED will not come on  
when the prefilters get clogged; clean the prefilters every time  
the cells are cleaned.  
The electronic cells and prefilters are clean and dry.  
The wiring connections inside the junction box or power  
box are properly made. See Fig. 24.  
That W8600E (if included) wiring connections are  
properly made.  
NOTE: If an ultrasonic room humidifier is used often,  
especially when filled with tap (undistilled) water, the  
cells will require more frequent washing. A white  
residue will accumulate on the cells from the  
minerals in the water.

F50E DUCT MOUNTED ELECTRONIC AIR CLEANER  
The cells can be washed in many home dishwashers, by  
soaking in a tub or at a do-it-yourself, coin-operated car wash.  
The prefilters can be vacuumed, brushed, sprayed with a  
garden hose, or washed with the electronic cells  
NOTE: Always wash the cells first, then the prefilters to keep  
heavy lint from getting caught in the cells.  
1. Use a container such as a laundry tub or trash  
container that is large enough to hold one or both cells.  
Automatic Dishwasher  
NOTE: Sharp corners on the cells can scratch the  
surface of a bathtub.  
CAUTION  
Burn Hazard.  
2. Dissolve about 3/4 cup of automatic dishwasher  
detergent in enough very hot water to cover the cells. 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 is completely dissolved, place the  
electronic cells in the container and let soak for 15 to  
20 minutes. Agitate the cells up and down a few times  
and then remove.  
4. Next, wash the prefilters the same way. Empty and rinse  
the wash container.  
5. Rinse the cells and prefilters 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 cells and prefilters no longer  
feels slippery.  
Can cause personal injury.  
Allow the cells 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 cells so these  
tubes 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, carefully  
position the cells to allow good water circulation.  
Use care to avoid damaging the cells when placing  
them in the dishwasher.  
Very dirty cells, especially from tobacco or cooking  
smoke, can discolor the plastic parts of the  
dishwasher. This discoloration is not harmful. To  
minimize it, wash the cells more frequently or try a  
different brand of detergent.  
6. Wipe the ionizer wires and red contact board on the  
end of cell with a clean cloth.  
Car Wash  
Use the hand sprayer at a coin-operated car wash to wash  
the cells and prefilters. 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 cells or the  
prefilters. Rinse until the water draining from the cells and  
prefilters no longer feels slippery.  
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 cells 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.  
2. If you are washing the prefilters with the cells, place  
them where they will not block the water flow to the  
electronic cells.  
3. 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 cells cool completely  
before removing, or wear protective gloves when  
removing the cells. Remember that water may be  
trapped in the tubes that support the collector plates; tip  
the cells so these tubes can drain.  
4. Wipe each ionizer wire and red contact board on top of  
the cell with a clean cloth.  
5. 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 cells. If dirt or residue  
seems excessive, wash the cells more often or try a  
different detergent.  
Reinstall the Cells and Prefilters  
1. Inspect the cells for broken ionizer wires and bent  
collector plates. Repair as necessary.  
2. Slide the prefilters into the upstream prefilter guides.  
3. Slide in the air cleaner cells so the air flow arrow points  
downstream and the handles face outward.  
4. Firmly close the access door.  
5. Turn on the air cleaner. If the cells and prefilters 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 two to three hours, or until dry.  
Ionizer Wire Replacement  
Broken or bent ionizer wires can cause a short to ground,  
often resulting in visible arcing or sparking. On air cleaners  
without a W8600E, any short in the ionizer section causes the  
neon light to go out. On air cleaners with a W8600E, any  
short in the ionizer or collector section lights the CHECK LED  
on the wall panel. The cell should not be used until the pieces  
of broken wire are removed. It can be used temporarily with  
one wire missing, although the wire should be replaced as  
soon as possible. See the Parts List section for order number.  
Soaking in Tub  
CAUTION  
Replacement wires come cut to length with eyelets on both  
ends for easy installation. To install:  
Hazardous Chemical.  
Can cause personal injury.  
1. Hook the eyelet on one end of the wire over the spring  
connector on one end of the cell. See Fig. 30. Be  
careful to avoid damaging the spring connector or other  
parts of the cell.  
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.

opposite spring connector and hook the eyelet over it.  
Reducing Ozone Odor  
CAUTION  
Electric Shock Hazard.  
Can cause personal injury.  
Always disconnect power and open the access door to  
discharge the high voltage power supply before  
opening the power supply cover.  
The electronic air cleaner generates a small amount of ozone  
in normal operation. During the first week or two of operation,  
the amount may be higher because of sharp edges on some  
of the new high voltage metal parts. However, normal use  
dulls these edges in a short time.  
SPRING  
CONNECTORS  
PRESS  
DOWN  
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 0.100 ppm. However, if  
desired, the ozone generated by the air cleaner can be  
reduced in one of two ways:

2. Clip out the J2 jumper 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.  
a. Turn off power to the air cleaner.

Test Button  
Power Supply Problem  
The TEST BUTTON is near the bottom of the access door.  
When pushed, it shorts from a hot collector plate to ground.  
See internal schematic, Fig. 36. The resulting arcing sound  
indicates that high voltage is being supplied to the collector.  
The solid state power supply controls current flow to the  
collector, so the arcing sound is only about half as loud as the  
sound on air cleaners with W919-style power supplies. On air  
cleaners with a W8600E, the CHECK LED comes on when  
the test button is pushed.  
CAUTION  
Can cause personal injury.  
Always turn off power and remove access door before  
removing power box or its cover.  
Electric Shock Hazard.

F50E DUCT MOUNTED ELECTRONIC AIR CLEANER  
The solid state power supply provided in this air cleaner has  
no field-serviceable components. If troubleshooting indicates  
a power supply problem, replace the entire power supply. See  
Parts List section for order number.  
4. Take out the two screws holding on the cover. Remove  
the cover.  
5. Replace the power box by resting it on the cabinet,  
lifting slightly to clear two screws, and pushing it  
straight toward the junction box. Do not bend the spring  
contacts sideways. The power plug must slide straight  
into the receptacle.  
To Access Power Supply  
1. Turn off power.  
6. Replace the access door and restore power.  
2. Remove the access door and loosen the two screws  
holding the power box. See Fig. 32.  
3. To pull the plug connector out of the receptacle in the  
junction box, lift slightly to clear screws, then pull the  
power box straight toward you.
