Operation
ALARM LAMPS
H.V. Alarm (High voltage alarm lamp)
The lamp lights in green when the high voltage transformer emits
properly the high voltage. If the piezoelectric transformer detects
an overload and shuts down the operation, the high-voltage alarm
lamp will light up in red.
When the H.V. lamp lights in red,
1) Immediately unplug the power cable or pull out the wires from
terminals.
2) Remove the fan cover and visually inspect around the electrode needles. If foreign particles are
adhered to the needles, refer to Cleaning Procedure and clean the needles.
Fan Alarm (Fan lock alarm lamp)

servicing to avoid accidents.
* Immediately after turning on the power, there is a moment that the fan lamp glows red.
This is not a malfunction.
