SAFETY DEVICES

In order to avoid tripping the safety devices during normal service (when the user has no faults), no purging of the down-
stream line should be carried out with the reducer installed.

4.6.1 - SAFETY DIAPHRAGM

NOTICE!
Tripping of the safety diaphragm (A) leads to replacement of the regulator.
The safety diaphragm (A) is a device that limits the dispersion of gas into the atmosphere in the event of a rupture of the
working diaphragm (B).
The tripping of the safety diaphragm (A) ensures a gas dispersion to the atmosphere of a maximum value of 30 l/h. The
micro-dispersion of gas into the atmosphere will allow the rupture of the working diaphragm (B) to be detected.
