CAUTION—Gas Filter Rupture upon Excessive Gas Supply Pressure
An excessive supply gas pressure can lead to an overpressure in the
detector and cause the gas filters to rupture. This can pose a health and
safety risk.
•
Turn on the gas supply only when the gas filters are properly
connected to the detector and the protective cover is properly
installed.
•
Observe the gas supply pressure range that is specified for the
detector. Do not exceed the maximum gas supply pressure.
•
Before you start the replacement of the gas filter assembly, make
sure that the gas supply and the detector gas flow are turned off.
CAUTION—Escaping Gas
Gas can escape from open gas connections when the detector gas flow
and/or the gas supply is turned on. The escaping gas can pose a health
and safety risk.
Make sure that the detector gas flow and the gas supply are turned off
before you remove the nebulizer, disconnect the gas tubes or remove
the gas filter assembly from the detector.
Turn on the gas supply and detector gas flow only when the nebulizer is
installed, the components in the gas flow path are properly connected,
and the protective cover of the gas filter assembly is installed.
