Cleaning or replacing the particle filter
In the event that the suction capacity of the gas presence detector is reduced through
particles or dust, it is recommended that the particle filter is cleaned or replaced. Due to
the transparent covering, the saturation level of the filter is directly visible.
EN
1. Unscrew the transparent protective cap of the particle filter.
2. Screw off the particle filter.
3. Clean the particle filter with compressed air.
If a cleaning of the filter is not possible (no compressed air pistol available or too
heavily contaminated), screw out the filter and replace it.
4. Tighten the protective cap again.
