5.5.4 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.
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.
CAUTION!
Damage to the sensor through incorrect cleaning
Overpressure in the console case can damage the sensor.
▶
No pressure should be applied at the connection hose.
4. Tighten the protective cap again.
6. Faults
CAUTION!
Physical injuries and damage to property and the environment
If faults cannot be eliminated by means of the listed measures, the
instrument must be taken out of operation immediately.
▶
Ensure that pressure or signal is no longer present and protect against
accidental commissioning.
▶
Contact the manufacturer.
▶
If a return is needed, please follow the instructions given in chapter 8.2
“Return”.
For contact details see chapter 1 “General information” or the back page
of the operating instructions.
