7.6 Dust filter cartridge replacing
The dust filter cartridge filters smallest dust particles from the combustion gases. Its saturation
depends on the sample material and its combustion characteristics. The filtering material of a
new cartridge is white. Replace the dust filter cartridge when the filtering material shows
coloration, or at least every 500 analysis.
1. Lift the dust filter cartridge (1) upwards.
2. Tilt its low end to the front and pull downwards.
3. Install a new cartridge by acting in reverse order.
Take care for the cartridge body to have the smaller diameter up and the bigger down.
