Filter replacement

The buzzer emits an acoustic signal when the airflow is too
low.
Make sure that:
- the shut-off damper is open
- the extraction arm is not fully folded
When the buzzer still continues, you must replace the filter
cassette(s).
As the pre filter is smaller and becomes more quickly saturated
than the HEPA filter, you can replace the pre filter cassette
several times before you finally need to replace the HEPA filter
cassette.
Personal protective equipment (PPE)
Wear respiratory protection and protective
gloves when you replace the filter
cassettes.
WaRNiNG
Do not replace the filter cassettes while the fan is
running.
WaRNiNG
Do not shake out or (vacuum) clean the used filter
