How to Clean the Casing
Remove the dirt over the casing with dry, soft cloth.
Never apply alcohol / thinner solvent / detergent, because the surface-active agent included in the
detergent etc., may deteriorate the ionizing performance.
How to Clean the Needle Electrode
Power supply to the N-3 should be shut off before cleaning the needle electrode.
Please follow the instructions below:
1) Remove the Nozzle.
Loosen the nozzle covering the
needle electrode.
2) Clean the needle electrode
Clean the tip of the needle with a
cotton stick. If it is especially dirty,
use a few drops of alcohol-wet cloth.
3) Place the Nozzle back in place.
Attach the Nozzle firmly. If it is
fastened too tightly, it may be
damaged or break, but if it is fastened
too lightly,
the nozzle may come off while in use
How to Replace the Needle Electrode
Replacement Needle Electrode is available as option: Model code GN-H
1) Remove the Nozzle.
Loosen the nozzle covering the needle electrode.
2) Replace the needle electrode
Remove the needle electrode with a dedicated screwdriver separately available. Attach
the new needle electrode on the terminal. Be careful not to pick your fingers with the
needle electrode.
3) Place the Nozzle back in place.
Attach the Nozzle firmly. If it is fastened too tightly, it may be damaged or break, but if it is
fastened too lightly, the nozzle may come off while in use.
Checking Ionizer’s Performance
Measure ion balance and decay time regularly by a charge plate monitor.
Reference: IEC61340-5-1, 2 ANSI EOS/ESD S3.1
Adjustment
The N-3 does not have an ion balance adjustment function. The ionizer is designed to maintain the
ion balance with a circuit board. If the ion balance is out of the specified range, please contact us.
