9. Close the nitrogen bottle.
10. Allow the sample to flow until all residual gas has been dissipated
from the lines as indicated by no flow on the sample flowmeter.
11. Unscrew the compression nuts on the both ends of the scrubber and
scrubber efficiency indicator, as shown in Figure 3–2 and Figure 3–3.
12. Gently pull the scrubber and scrubber efficiency indicator free from
the connections.
13. Cap the inlet and outlet ends of the used scrubber and scrubber
efficiency indicator.
14. Insert the inlet, outlet connections of a new scrubber and scrubber
efficiency indicator into the compression fittings making sure that
each are oriented correctly according to the flow pattern shown in
Figure 3–2.
15. Tighten all new fittings 1-1/4 turns with a wrench from finger tight.
For connections with previously swaged ferrules, thread the nut to
the previously pulled up position, then tighten slightly with a wrench.
16. Open the nitrogen bottle once again and check all connections for
gas leaks. SpectraSensors recommends using a liquid leak detector.
17. Disconnect the bottle of nitrogen and connect the process gas line to
the sample supply port (at the specified supply pressure).
18. Turn on the process gas.
19. Open the sample flowmeter metering valve to approximately the
specified flow for the measurement cell.
20. If required, open and/or adjust the sample pressure regulator to the
specified setpoint for the measurement cell.
21. Adjust the sample flowmeter metering valve to the specified flow for
the measurement cell.
22. Confirm the sample flow and pressure setpoints and readjust the
flowmeter metering valves and pressure regulators to the specified
setpoints, if necessary.
23. Power up the analyzer according to the procedure under “Powering
Down the Analyzer” in the Firmware Manual.
The adjustment setpoints of the analyzer flowmeters and
pressure regulators will be interactive and may require
readjustment multiple times until the final setpoints are obtained.
The analyzer system is designed for the sample flow rate
specified. A lower than specified sample flow rate may adversely
affect analyzer performance. If you are unable to attain the
specified sample flow rate, refer to “Service Contact” on page
B-11.
