Possible leakages on gas path
Tighten the threaded joints in accordance with the mounting specifications of the
manufacturer using a suitable open-ended wrench. In the process, make sure that you
counter properly. Otherwise, there is a danger that the gas path will leak.
Danger of poisoning by escaping gas
Components which come into contact with the sample gas must be resistant to it.
Otherwise, there is a danger that the gas path will leak and that sample gas will accumulate
in the analyzer.
Take appropriate precautions to prevent gas from escaping, e.g. by monitoring the flow
outside the analyzer.
