– Control diode turns green:
air flow sufficient and therefore filter OK
– Control diode turns red:
air flow too low, change filters.
Operating instructions
When working with renovation machines
separate safety exhaust systems are
required to exhaust the high volume of dust
directly into the machine. The remaining fine
dust in the room air is extracted and filtered
out by the air purifier. This prevents dust
from entering other areas.
The continuing collection of dust clogs the
filters more and more over time and the air
flow rate is continuously reduced until the red
warning light comes on. At this point the filters
must be replaced.
The product is fitted with a LED display
(green/red), which warns of a blocked filter.
– When the LED turns red, the G3 and G4
filters or must be replaced.
– If the warning light shows red again
immediately after replacing the filters, the
H14 filter must also be replaced
