2. Hold the opposite eyelet with a needlenose pliers and
stretch the wire the length of the cell. Depress the
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.
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 of the air
cleaner. Make sure particles from the air filter cannot fall
into the air cleaner.
CAUTION
Only a trained service technician should perform the
following procedure.
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.
b. Open the access door to discharge the high
voltage power supply.
c. If power supply is remotely mounted, make sure
the access door is left open. Remove the power
box cover. See Fig. 32.
d. Find the J2 jumper and clip it out. See Fig. 31.
e. Replace power supply cover and access door.
Turn on power.
