WARNING
Risk of unexpected occurring overpressure
A soiled or non-functioning overpressure
safety valve is not able to compensate for
suddenly occurring overpressure in the
breathing system.
Perform the leakage test before start-up of
the device. Observe the test results of the
overpressure safety valve.
