Screw the cartridge into the facepiece inhalation port. This port is found on the right hand side, as you
are looking at the front of the facepiece.
2.
When the cartridge first contacts the inlet port gasket, tighten the cartridge up to an extra 1/4 turn to
insure a tight, leak free seal.

Remove cartridge from the facepiece by unscrewing counter clockwise.
2.
Grasp the inhalation valve body seat at the two tabs that stick out away from the facepiece, and pull
straight away until it is unseated from the side port.
CAUTION
Do not pull on the spokes of the inhalation valve body seat as this may break the spokes and require
replacement of the inhalation valve kit
3.
Set aside the inhalation valve assembly on a clean surface for later installation.
