When pressing the “Air cleaning button” by remote controller,high voltage output(pin 18 of microcomputer)
supply voltage 5V to the high voltage generator.In other words,the high voltage generator is activated
to produce a high-voltage supplied for the electrode.

·

When having the overload current,ICP1 will be open to forcibly stop the supply of power supply voltage
12V of the high-voltage generator.

High voltage output

High-Voltage
generator

Electrode

The High-Voltage generator(electric dust collector)causes the electrode to discharge so that dirt in the
air flowing into air conditioner can be electrified,resulting in the aie being purified by mesh filters.The
high-voltage discharge electrode applies a voltage of about 6KV.
