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).
