Chapter 7 Maintenance and
WARNING
Slipping, tripping and falling when changing the upper filters.
Lock casters, use safe ladders/ steps (see also DGUV Information 208-016 -
Handlungsanleitung für den Umgang mit Ladern und Trittern (BGI 694).
Always ensure a secure footing during filter replacement.
CAUTION
Risk of crushing and impact.
The dedusting unit can unintentionally roll away if it is standing on uneven ground
and/or on level ground with unlocked rollers.
Place the dedusting unit on a firm, flat and horizontal surface.
Lock the rollers.
Requirements for changing the filter
The air filter inserts must be replaced at the latest when the permissible final
pressure difference is reached or in the event of technical or hygienic functional
defects.
Only air filters tested according to DIN EN 779 or DIN EN 1822 may be used. These
are individually and clearly visibly marked.
The coarse dust prefilter is at least class G4, the second filter stage (main filter) at
least F7, better F8 or F9.
For hygienic reasons, the maximum service life should be limited:
•
12 months for the 1st filter stage
•
24 months for the 2nd filter stage
If the intervals are not observed, there is a danger that particles that have already
been filtered will be "carried away" again by the increasing system pressure, thus
contaminating the air again.
Gas filters (e.g. activated carbon) do not influence the pressure loss during normal
operation.
NOTE
When changing a Hepa or ULPA filter, the inside of the filter material must not
be touched under any circumstances.
