Pipe System

Check the pipe system and the air sampling openings for obstruction in areas susceptible to
dust particles or icing. If necessary, blow out the pipe system and air sampling openings with
blast air. Use a mobile cylinder of compressed air (blowing-out system) or activate the manual
blowing-out system located on site. The components (compressors, compressed air
containers, dryers) required to supply the compressed air can be obtained directly from the
relevant compressed air system suppliers.
Caution!
Before blowing out the pipe system, disconnect the FCS-320-TM from the pipe system;
!
otherwise, the airflow sensor will be damaged.
