8.13 Packing and storage
Endress+Hauser’s OXY5500 analyzers and auxiliary equipment are shipped from the factory in appropriate
packaging. Depending on the size and weight, the packaging may consist of a cardboard-skinned container or a
wooden crate. All inlets and vents are capped and protected when packaged for shipment.
If the equipment is to be shipped or stored for any length of time, it should be packed in the original packaging when
shipped from the factory. If the 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.
8.13.1 Preparing 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, regulated to the specified sample supply pressure, 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.
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 and outlets to prevent foreign material such as dust or water from entering the system).
12. Pack the equipment in the original packaging in which it was shipped, if available. If the original packaging
material is no longer available, the equipment should be adequately secured to prevent excessive shock or
vibration.
13. If returning the analyzer to the factory, complete the Decontamination Form provided by Endress+Hauser (refer
to "Service repair order") and attach to the outside of the shipping package as instructed before shipping.
