Modification To Reduce Ozone Odor - Honeywell F300 Product Data

F300 ELECTRONIC AIR CLEANER
Replacing Ionizer Wires
Broken or bent ionizer wires can cause an electrical short to
ground, often resulting in visible arcing or sparking. Do not use
cells until broken wires are removed. Cells can be used
temporarily with one wire missing, but replace the wire as soon
as possible.
Replacement wires are supplied cut to length with eyelets on
both ends for easy installation. See Parts and Accessories Not
Illustrated section. To install:
1. Hook the eyelet on one end of the wire over the spring
connector on one end of the cell. See Fig. 15. Be careful
to avoid damaging spring connectors or other parts of
the cells.
2. Hold the opposite eyelet with a needle nose pliers and
stretch the wire the length of the cell. Depress the
opposite spring connector and hook the eyelet over it.
3. Check the cell for short circuits using an ohmmeter; see
Fig. 16. Check the resistance between the frame of the
cell and both the ionizer and the collector contacts. In
each case, the resistance should be infinite.

Modification to Reduce Ozone Odor

CAUTION
Electric Shock Hazard.
Can cause personal injury.
Always disconnect power and open access door 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 0.003 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.
