Internal purge air filter
To protect the laser optics against dirt and for the device self-test, an integrated fine particle filter pro-
duces particle-free air. Its service life is several years, even with continuous operation. Should the mes-
sage
“CHECK NOZZLE
AND AIR INLET”
appear several times even though the sample intake is clear and there is no unallowable overpressure
on the sample intake, this indicates a problem with the purge air supply. The problem can usually be
corrected by replacing the filter, but this has to be carried out by trained service personnel. Please con-
tact the nearest customer service department in this case or ask your dealer.
