Service and maintenance

7.2 Analyzer

7.2 Analyzer
Following maintenance or the retrofitting of parts associated with explosion protection, the
analyzer may only be started when an Ex specialist has ensured that the analyzer has the
essential features and meets the requirements for explosion protection and issues a certificate
to this effect and/or has attached a test symbol to the equipment.
Annual maintenance of the analyzer must be carried out to check the electrical safety and
reliable operation, in particular the tightness of the sample gas path within the analyzer.
Furthermore, a leak test must be carried out following each intervention in the gas path
(containment system). The leak test is described in Section → Leak testing of containment
system (Page 67).
The owner can extend maintenance intervals in individual cases if no negative effects can be
expected on wetted parts materials (gaskets in particular).
Further information on maintenance of the analyzer can be found in the associated Operating
Instructions.
