Fig. 23. Use ohmmeter to check electronic cells
for short circuits.
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. Normal
use quickly dulls these edges.
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:
1. Install an activated carbon filter downstream from the
air cleaner. Make sure particles from the air filter
cannot fall into the air cleaner.
WARNING
Electric Shock Hazard.
Can cause personal injury.
Only a trained service technician should perform the
following procedure.
2. This will reduce ozone production about 20 to 25
percent and reduce efficiency about seven to ten
percent, depending on actual airflow delivered by the
furnace blower.
a. Unplug or disconnect power supply to the air
cleaner.
b. Open the access door.
c. Remove the power box cover. See Fig. 24.
d. Locate J5 shorting bar on the power supply. See
Fig. 25. Remove the shorting bar and reinstall on
only one pin.
NOTE: The ozone will be reduced, but the shorting
bar is available for reinstallation if needed.
e. Replace the power supply cover and access the
door. Turn on the power.
f. Repeat the checkout procedure before leaving
the job.
