Fidas24 – Shutting down the gas analyzer
In the case of a temporary shutdown:
1. Shut off the sample gas supply at the sampling point.
2. Purge the sample gas line with nitrogen for at least
5 minutes, from the sampling point.
3. Set the gas analyzer to standby mode, refer to
In case of corrosive and combustion gases set the gas
analyzer to standby operation with detector purging.
4. Shut off combustion air supply and combustion gas
supply.
In the case of a long-term shutdown, carry out the following in
addition:
5. Shut off instrument air supply.
6. Switch off the gas analyzer power supply.
7. Remove the gas lines from the gas analyzer ports. Tightly
seal the gas ports.
8. Disconnect the electrical leads from the gas analyzer.
Packing the Gas Analyzer
1. Remove adapters from the gas ports and tightly seal the gas
ports.
2. If the original packaging is not available, wrap the gas
analyzer in bubble wrap or corrugated cardboard. For
overseas shipment, always add a desiccant (e.g., silica gel)
and hermetically seal the gas analyzer plus desiccant in a
layer of polythene that is 0.2 mm thick. The amount of drying
agent should be appropriate for the package volume and the
expected shipping duration (at least 3 months).
3. Pack the gas analyzer in an adequately sized box lined with
shock-absorbing material (foam or similar). The thickness of
the shock-absorbing material should be adequate for the
weight of the gas analyzer and the mode of dispatch. When
shipping overseas, additionally line the box with a double
layer of bitumen paper.
4. Mark the box as "Fragile Goods".
