7.0.6 Procedure for Connecting the Sample Lines
Refer to Figure 16
WARNING
Electrical Hazard, Personal Injury and Equipment Damage: Do NOT
perform any internal service on an energized or gas supplied analyzer. When
performing maintenance on the unit, it is necessary to disconnect the power
source from the unit, and turn off the gas supply lines (sample gas and zero
gas).
1. Turn off the main power disconnect and turn off all gas supply lines.
2. Remove the port caps and any other obstructions from the sample path (inlet and exhaust
ports).
3. Install the appropriate fittings on the sample supply and exhaust lines (see Preparing
Sample Gas Lines on page 50).
4. Install a pressure relief mechanism if necessary (if sampling from a pressure other than
ambient).
5. Ensure a clean sample stream – install a 10 micron particulate filter on the inlet side of the
sample plumbing if necessary.
6. Install/connect stream switching lines and solenoids if applicable.
7. Connect sample supply and exhaust lines to the Servomex SpectraScan sample inlet and
exhaust ports.
8. Ensure proper sample gas and zero gas temperature and conditioning. In general, sample
conditioning is application dependent, see the Application data for more specific
information. However, samples entering the Servomex SpectraScan Gas Analyzer must
be “clean and dry” free of liquids and particulates. Sample cell is heated to 60°C. Any
sample above 50°C may have condensation or overheating risks.
CAUTION
Equipment Damage: The sample stream must be clean of particles that could block the
light path and potentially accumulate on the windows, and potentially damage the unit. It is
ultimately the user’s responsibility to ensure a clean sample stream. We recommend an
inline 10 micron particulate filter for most applications. Contact Servomex for more
information.
9. Check sample path (lines and connections) and zero gas path for leaks, by alternately
turning one on and the other off. Repair or replace to resolve any leaks that are found; the
Servomex SpectraScan Gas Analyzer must be operated in a leak-free environment.
10. Turn on the main power (at the disconnect).
11. Set supply and exhaust valves in the proper configuration for remote operation.
