Adjust the power supply high voltage output
Electronic cell generates a small amount of ozone, about 0.005 to 0.010 parts per million (ppm). The average person can detect
the odor of ozone in concentrations as low as 0.003 to 0.010 ppm. 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 higher than 0.100 ppm. If desired, the ozone generated by the air purifier can be
reduced by cleaning the cell, replacing the carbon filter or adjusting the high voltage power supply to produce a lower high
voltage output. However, the adjustment of the power supply will reduce ozone production but will also reduce air cleaning
efficiency.
Adjust the high voltage output by
rotating the adjustor with plastic
screwdriver.
( - ) Counter clockwise to
decrease high voltage
( + ) Clockwise to
increase high
1. Open the bottom plate.
2. Rotate the bolt on the blue color adjustor with flat screwdriver. To avoid electrical shock, you can unplug the power cord.
3. To decrease the high voltage output to the cell, rotate the bolt in counter clockwise direction. To increase the high voltage output,
rotate it in clock wise direction.
Replace the power supply
When you replace the power supply follow the below steps and do the reverse operation for installing.
1. Pull out the low voltage wire plug.
4. Unplug the transformer
connection.
5. Unscrew the ground wire
connection .
6. Remove other 3 screws on the
power supply circuit board.
2. Remove the high voltage wire
plug.
3. Unplug the check wire
connection.
Disassemble the power supply
