1
REMOVE OLD EXHALATION VALVES
While firmly holding onto the exhalation valve, pull the facepiece away from the exhalation valve until a
portion of the valve becomes unseated. Continue to pull the facepiece and push the valve until the valve is
free. Dispose of the exhalation valve according to the same rules and regulations as the SOTR filter.
NOTE:
Always replace both exhalation valves at the same time to ensure your mask will function properly.
2
INSTALL NEW EXHALATION VALVES
Push a portion of the valve seat retention groove partially over the facepiece opening. Stretch the remainder
of the facepiece into the retention groove. Ensure that the valve seat is flush and the facepiece is fully inserted
within the valve seat retention groove so that it is sealed.
NOTE:
Always install the valves so that the valve openings are facing downwards, away from the user’s eyes.
