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. There is also a risk to the eyes if there is
a direct view of the UV-C lamp.
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 respiratory mask! We recommend: respiratory
protection half mask DIN EN 141/143 protection level P3. For all maintenance
work ensure a cautious handling of filter elements and components in order to
avoid whirling up dust.
Notes regarding SARS-CoV-2 (Coronavirus)
In relation with SARS-CoV-2, the german RKI (Robert-Koch-Institut) has
published a section on its website with information on the disposal of waste::
https://www.rki.de/DE/Content/InfAZ/N/Neuartiges_Coronavirus/Hygiene.html
Please note that the information provided there (e.g. on waste disposal) is
updated from time to time. So always take into account the current status of
waste disposal.
We recommend: Stow the changed (filter) elements in tear-resistant and tightly
closed plastic bags before disposal, so that contact is avoided in the further
disposal process. Disposal can take place via the mixed waste / residual waste.
The operator is obliged to store and dispose of the collected dust 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.
