Connecting the gas lines

NOTICE
Damage to the gas analyzer
Damage to the gas analyzer due to condensing sample gas
during commissioning.
• Observe the condition of the sample gas inlet of the
analyzer modules.
• Purge the sample gas path before commissioning, see
Purge sample gas path and analyzer housing on page 103.
• Do not connect the sample gas until the gas analyzer has
reached room temperature and after the warm-up phase
has elapsed, see Duration of the Warm-up Phase on
page 103.
Connecting the hose lines
Slide the hoses with an inside diameter of 4 mm onto the hose
nozzles and fasten with hose clamps.
Connecting the piping
Connect stainless steel pipes professionally to the screwed
connection, taking into account the tightness requirements.
Installing the fine filter
A preinstalled fine filter is Included in the scope of delivery (see
Scope of delivery on page 15) of the gas analyzer (one-way filter,
order number 769144 – not for Fidas24).
When installing the fine filter, attach the short hose piece to the
sample gas inlet; connect the sample gas line to the long hose
piece with the hose nozzle.
Installing the flowmeter
Install a flowmeter or flow monitor with needle valve before the
sample gas inlet and if necessary before the purge gas inlet to
be able to adjust and monitor the gas flow.
Provide for sample gas line purging
Install a shut-off valve in the sample gas line (highly
recommended for pressurized sample gas) and provide the
option of introducing an inert gas, such as nitrogen, from the
gas sampling point, for purging of the sample gas line.
Exhaust gas lines
The exhaust gases of the gas analyzers are dissipated via the
sample gas outlets. The exhaust gases can be discharged into
the atmosphere via a common exhaust gas line.
Note
Dispose of corrosive, toxic or combustion exhaust gases
according to the regulations!
Observe the following points when connecting the exhaust gas
lines:
• Guide the exhaust gases from the gas analyzer directly
into the atmosphere or in depressurized state through
the shortest possible line with a large inside diameter, or
into an exhaust pipe.
• Do not install any throttle sections or shut-off valves in
the exhaust gas line!
For Fidas24, also observe the information in Connecting
•
the exhaust air line on page 88!
