the sampling lines as free from contamination as possible. If mirror
contamination is suspected, see “Cleaning the Mirrors” on page B-3.

1. Make sure that a filter or membrane separator is installed ahead of
the analyzer and is operating normally. Replace the membrane or
filter, if necessary (refer to “Replacing the membrane
separators” on page B-15 or “Replacing the filter” on page
B-15).
2. If mirror contamination is suspected, refer to “Cleaning the
Mirrors” on page B-3.
3. Turn off the sample valve at the tap in accordance with site lock-out,
tag-out rules.
4. Disconnect the gas sampling line from the sample supply port of the
analyzer.
5. Wash the sampling line with a suitable solvent 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. SpectraSensors recommends
using a liquid leak detector.
Excessive Sampling Gas Temperatures and
Pressures
The embedded software is designed to produce accurate measurements only
within the allowable cell operating range (refer to the system drawings in
Appendix A and/or calibration report).
Pressures and temperatures outside this range will trigger a Pressure Low
Alarm, Pressure High Alarm, Temp Low Alarm, or Temp High Alarm
fault.
If liquid enters the cell and accumulates on the internal optics, a
Laser Power too Low fault will result.
The cell temperature operating range for analyzers that are
equipped with heated enclosures is equal to the enclosure
temperature setpoint ±5 ° C.
