interfere with the measurement in some other way. Although the analyzer is designed to withstand some
contamination, it is recommended to always keep the sampling lines as contamination free as possible.
6.4.1 To keep the sampling lines clean
1. Make sure that a membrane separator filter (included with most systems) is installed ahead of the analyzer and
operating normally. Replace the membrane if necessary. If liquid enters the cell and accumulates on the internal
optics, a Laser Power Low Alrm fault will result.
2. If mirror contamination is suspected, see Cleaning the mirrors → .
3. Turn off the sample valve at the tap in accordance with site lockout, tagout rules.
4. Disconnect the gas sampling line from the sample supply port of the analyzer.
5. Wash the sampling line with alcohol or acetone and blow dry with mild pressure from a dry air or nitrogen
source.
6. Once the sampling line is completely free of solvent, reconnect the gas sampling line to the sample supply port of
the analyzer.
7. Check all connections for gas leaks. Endress+Hauser recommends using a liquid leak detector.
6.4.2 Mirror contamination
If contamination makes its way into the cell and accumulates on the internal optics, a Laser Power Low Alrm fault
will result.
