5. REPLACING THE SPEECH MEMBRANE:
The mask's inner mask can be removed by pulling gently. The screw ring can be
screwed out and the speech membrane's cover removed. Then take out the membrane
and the O-ring. A new O-ring and membrane can then be fitted. The cover and screw
ring are mounted once again and the inner mask refitted. After replacement of the
speech membrane, a leakage test must be carried out using a suitable leakage analyser.
6. REPLACING THE VALVE HOUSING (COMPLETE):
The mask's inner mask can be removed by pulling it gently. The closing band can be
loosened with a screwdriver and removed. "Support for valve housing" can be removed
from the visor frame and the complete valve housing can be pulled out of the body of
the mask. A new original valve housing can be put in place, "support for valve housing"
fitted onto the visor frame, and finally the closing band can be refitted and tightened
properly. After replacement of the complete valve housing, a leakage test must be
carried out using a suitable leakage analyser
