4-4-2-1 Preparations
To carry out the routine tests the following
steps have to be performed:
• Disconnect the analyzer and the
pressurization unit from power.
• Seal the purge medium outlet at the
pressurization unit (1“ opening at the left
side).
• Disconnect the containment system
gas connectors from the external gas
lines.
• Disconnect one of the containment
system gas connectors inside the
analyzer and seal the other one.
(Remark: Now it must be possible set
the enclosure under pressure by
applying an external gas (e.g.
compressed air) to the gas connector.)
• Connect an external source of
compressed air as described in the
drawing on the next page (fig. 4-2).
4-4-2 System with 90 mbar Operating Pressure
Required tools:
• Manometer with full scale between
150 and 200 mbar and resolution of
0.1 mbar.
• Flow meter with full scale between 5
and 10 l/min, resolution 0.1 l/min.
• Test gas: Compressd air or Nitrogen,
pressure reduced to max. 1,500 hPa.
• Pressure regulator to reduce the pressure
to values of 95 resp. 143 mbar.
• Equipment for flow regulation
• 1 plug to seal the purge gas outlet
(size 1“)
• 1 plug to seal gas outlet (size 6 mm)
