1.
Install 202614 Carbon Filters (sold separately).
a. Turn the air cleaner power switch to the OFF posi-
tion.
b. Remove the pre-filter and two electronic cells.
c. Install carbon filters in the rear of the air cleaner
cabinet. First insert the bottom of the carbon filter
into the rear channel; then rotate the top of the
carbon filter back to snap it into place under the
upper clip.
d. Replace electronic cells and pre-filter.
WARNING
Electric Shock Hazard.
Can cause personal injury.
Only a trained service technician should perform
the following procedure.
2.
Ozone production may be reduced by about 20 to
25 percent by moving the EFFY Jumper on the power
supply. Particle collection efficiency can also be
reduced by about seven to ten percent.
a. Disconnect power to the air cleaner.
b. Remove the pre-filter and two electronic cells.
c. Remove three screws from the power supply tray
along the top of the air cleaner.
d. Lower the front edge of the power supply tray to
expose the power supply.
e. Locate the EFFY shorting bar on the power sup-
ply. See Fig. 14. Remove the shorting bar and
reinstall on only one pin. Ozone will be reduced
and the shorting bar will be available for reinstal-
lation, if needed.
f.
Raise the front edge of the power supply tray and
reinstall the three screws.
g. Replace electronic cells and pre-filter.
h. Turn on the power and repeat the Check Air
Cleaner Operation procedure in the Checkout
section.

ELECTRICAL
TROUBLESHOOTING
WARNING
Electric Shock Hazard.
Can cause personal injury or equipment damage.
The following procedures expose hazardous live
parts and are for use only by qualified personnel.
Disconnect power between checks and proceed
carefully.
Tools and Equipment
Troubleshooting the electronic air cleaner requires:
• Needlenose pliers for stringing ionizer wires and
inserting edge connectors.
• Ohmmeter.
Test Button
When pushed, the Test button shorts from collector voltage
to ground. 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. The
CHECK indicator activates when the Test button is held
down.
CHECK Indicator
The CHECK indicator activates to indicate the following
problems:
• Excessive dirt loading.
• Partial shorting of collector.
• Continuous ionizer or collector arcing.
• Power supply failure.
• Excessive ionizer current.
• Any condition causing a major reduction in high voltage.
Power Supply
WARNING
Electric Shock Hazard.
Can cause personal injury.
Turn off power before accessing the power supply.
The solid state power supply can be replaced when
troubleshooting indicates a problem.
Troubleshooting Procedure
The electronic air cleaner troubleshooting diagram shows
how to quickly isolate a problem in the air cleaner.
Although an ohmmeter is needed in some steps, the
primary diagnostic tools are the status indicators and the
Test button. See Fig. 15.
