Power Supply
CAUTION
Electric Shock Hazard
Can cause personal injury
Before opening the power supply cover, always
disconnect power and open the access door or
grille to discharge the high voltage power supply.
The solid state Power supply has no field-serviceable
components. If troubleshooting indicates a power supply
problem, replace the entire power supply. See Table 1.

Modification to Reduce Ozone
Odor
In normal operation, the electronic air cleaner generates a
small amount of ozone. 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 as 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 filter
cannot fall into the air cleaner.
2. On F57, make sure performance switch is in the
low position.
CAUTION
Only a trained service technician should
perform the following procedure.
On all other 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 remote mounted, make sure
access door or grille is open. Remove the power
box cover.
d. Locate J8 Shorting Bar on the power supply.
See Fig. 18. Remove the shorting bar and rein-
stall on only one pin.
NOTE: The ozone will be reduced, but the shorting bar
is available for reinstallation if needed.
e. Replace power supply cover and access door or
grille. Turn on power.
