S TDLAS Gas Analyzer BA02191C
B-26 Endress+Hauser
If analyzer has been installed and or operated (even for purposes of a
demonstration), the system should first be decontaminated (purged with an
inert gas) before powering down the analyzer.
To prepare the analyzer for shipment or storage
1. Shut off the process gas flow.
2. Allow all residual gas to dissipate from the lines.
3. Connect a purge supply (e.g., dry nitrogen), regulated to the
specified sample supply pressure (refer to drawings in Appendix A),
to the sample supply port.
4. Confirm that any valves controlling the sample flow effluent to the
low pressure flare or atmospheric vent are open.
5. Turn on the purge supply and purge the system to clear any residual
process gases. For differential systems, make sure to purge the
scrubber for several dry cycles.
If necessary, dry cycles can be initiated by pressing the # key
followed by the 2 key to enter Mode 2, and then pressing the # key
followed by the 1 key to return to Mode 1.
6. Turn off the purge supply.
7. Allow all residual gas to dissipate from the lines.
8. Close any valves controlling the sample flow effluent to the low
pressure flare or atmospheric vent.
9. Disconnect power to the system.
10. Disconnect all tubing and signal connections.
11. Cap all inlets, outlets, vents, conduit or gland openings (to prevent
foreign material such as dust or water from entering the system)
using the original fittings supplied as part of the packaging from the
factory.
12. Pack the equipment in the original packaging in which it was
shipped. If the original packaging material is no longer available, the
equipment should be adequately secured (to prevent excessive
shock or vibration) within a weather-proof enclosure. Refer to
“Service Repair Order” on page B-25 for any questions related to
packaging.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
of the sample and prescribed safety precautions before installing,
operating or maintaining the analyzer.
