Reducing Ozone Odor Modification
WARNING
Electric Shock Hazard.
Can cause personal injury.
Disconnect power before opening 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. Normal use quickly dulls
these edges.
The average person can detect the odor of ozone in
concentrations as low as 0.0003 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 US 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 over 0.100 ppm.To reduce the ozone
generated by the air cleaner:
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 cab-
inet. First insert the bottom of the carbon filter into
the rear channel; then rotate the top of the carbon fil-
ter back to snap it into place under the upper clip.
d. Replace electronic cells and pre-filter.
WARNING

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 J5 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 J5 shorting bar on the power supply. See
Fig. 10. Remove the shorting bar and reinstall on
only one pin. Ozone will be reduced and the short-
ing bar will be available for reinstallation, 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.
