Maintenance intervals and work
Hazard due to a sudden release of pressure!
Never remove any parts of the filter, or manipulate the same in any way,
for as long as the filter is still pressurised! A sudden escape of pressure
may cause serious injuries.
Depressurise the filter before carrying out any work on the filter.
Danger due to release of a critical gas!
The release of a critical (explosive, flammable, poisonous) gas from the
network can constitute a considerable risk for man and environment.
Therefore heed the following before working on filters for critical gases
— flush the pipe section in question with inert gas
— have the notes on hazardous substances for the used gas ready
— take appropriate protection measures
— verify the absence of an explosive atmosphere
