Initial startup of the analyzer system should be performed by trained personnel of the
manufacturer or the supplier.
WARNING!
The analyzer system must stand in its operating position for about 24 hours prior to
start-up.
Purge the combustion gas line before analyzer system start-up. This should ensure that
the combustion gas line is free of impurities – especially containing hydrocarbons –
that could lead to erroneous measurement values. Purge the combustion gas line for
approx. 20 seconds with a nitrogen flow of approx. 100 l/h.
