Installing the Gas Analyzer

Installing the Gas Connections
NOTES
We strongly recommend that you install the gas connections before the
gas analyzer is installed, since the gas ports are now easily accessible.
The fittings must be clean and free of residue! Contaminants can enter
the analyzer and damage it or lead to false measurement results!
Do not use sealing compound to seal the gas connections! Constituents
of the sealing compound can lead to false measurement results! Use
PTFE sealing tape!
Follow the manufacturer's installation instructions for the fittings!

Requisite Material
Screwed fittings with nozzles (supplied) or threaded connections with 1/8
NPT threads and PTFE sealing tape
Installing the Gas Connections
Screw out the yellow plastic screwing caps (5 mm hexagon socket) from
the connectors. Tightly wind two layers of PTFE sealing tape around the
thread of the screwed fittings or threaded connections in a clockwise
direction and screw into the gas ports. Approx. 2 threads usually remain
visible after the assembly.
NOTE
Screw in the fittings carefully and not too tightly!
Checking the Seal Integrity of the Sample Gas Feed Path
The tightness of the sample gas feed path was checked in the factory.
However since it may have been affected during transport of the gas
analyzer (e.g. by strong vibrations), we recommend that it is checked
(see page 119) before the instrument is commissioned at the installation
site.
NOTE
We strongly recommend that the tightness of the sample gas feed path is
checked before the gas analyzer is mounted, since the housing must be
opened in the event of a leak.
