7. Maintenance
In accordance with national regulations, the operator is obliged to carry out repeat and functional tests.
Unless otherwise specified by national regulations, we recommend regular visual inspections and
functional tests of the device as described in the chapter “Maintenance intervals”.
You find the chapter “Maintenance intervals” at the end of the document. The general
maintenance (visual inspection, etc.) is also explained there.
In the chapter “Maintenance intervals” there is information on the maintenance intervals of the filter
elements. But these are only recommendations. Depending on the application (multi-shift operation,
dust generation, ...) it may be necessary for the operator to change the maintenance intervals.
In this chapter the maintenance work which is caused by wear caused during operation is described.
WARNING
Work on the open system entails the risk of electrical shock or accidental restart the
system. Both pose a danger to life and limb.
When cleaning and servicing equipment during the replacement of parts or when changing
to another function, set the device to maintenance condition first (see chapter “Reset to
maintenance state”).
A recommissioning of the device must only occur if it is ensured that the device is
functionally equivalent to the original state.
CAUTION
Hazards to the respiratory tracts are possible.
All maintenance work must only be carried out in well-ventilated rooms and while wearing an
appropriate protective equipment ! For all maintenance work ensure a cautious handling of
filter elements and components in order to avoid whirling up dust.
The operator is obliged to store and dispose of the collected dust and mud in accordance with
national or regional regulations. For all maintenance or cleaning work please refer to the applying
environmental regulations. Pollutants and filter elements must be disposed of or stored according
to the regulations as well. If you have any doubts, we recommend contacting a disposal
contractor in your area.
