Modification To Reduce Ozone
Odor
WARNING
Electric Shock Hazard.
Can cause personal injury.
Always disconnect power before opening the
power supply cover.
The electronic air cleaner generates a small amount of
ozone in normal operation. During the first or second
week 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 does not
exceed 0.050 ppm. As a comparison, the outdoor ozone
level in major cities is sometimes as high as 0.100 ppm.
However, if desired, the ozone generated by the air
cleaner can be reduced in one of three 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. On F57 and F90 models, make sure the perfor-
mance switch is in the low position.
3. On all models, the procedure explained below will
reduce ozone production about 20 to 25 percent,
and efficiency about 7 to 10 percent.
a. Turn off power to the air cleaner.
b. Open the access door or grille to discharge the
high-voltage power supply.
c. If power supply is remotely mounted, make sure
access door or grille is open. Remove the power
M33490
box cover.
d. Locate J8 shorting bar on the power supply. See
Fig. 24. Remove the shorting bar and reinstall
on only one pin.
NOTE: This reduces to ozone, but the shorting bar
e. Replace power supply cover and access door or
grille. Turn on power.
f. Repeat checkout procedure before leaving the
job.
