Replacing filter mats

When your converter is equipped with filter mats, check the filter mats for accumulated dirt at
regular intervals. You must replace the filter mats if the amount of accumulated dirt means that
an insufficient amount of air is entering the converter.
Note
Replacing the filter mats
If you do not replace dirty filter mats, this can cause a premature thermal shutdown of the drive.
Make sure that no dirt can enter the cabinet.
When disposing the filter mats comply with the applicable legal stipulations.
The ordering data for the filter mats is provided in the spare parts list.
