6. MAINTENANCE
After installation, the CleanWave
®
filter requires almost no maintenance.
We only recommend a periodic (e.g. annual) inspection.
This inspection must be done with no voltage by a qualified technician.
The working sequence is the following :
- Switch off the power of the CleanWave
®
filter.
- Open the housing in order to access the filter. In the case of the IP21 CleanWave
®
filter,
- Unscrew and remove the lower part of the front panel (see fig. 3 and 7).
- Check that there is no voltage on the terminals.
- Visually check the general aspect of the filter, especially that there is no excessive dust on
the Lo and Zo chokes.
- If necessary, clean the Lo and Zo with compressed air or with a vacuum-cleaner.
- Check the tightening of the power terminals.
- Close the housing.
- Power up the filter.
