
Unscrew the screws (crosshead Phillips), loosen the visor frames, and remove the visor (fig. A).

Place a new visor in the faceblank groove (see the marking "up/down" on the visor). Align the
check marks of the visor and faceblank with each other (fig. B).

Press the upper frame into place (fig. C).

Bend the mask at the connector to give space for the lower frame under the connector support
piece (fig. D). Tighten both screws.

Carry out the leak-tightness test (point 5.1).
5.3 Replacing the exhalation valve disc

Pull out the connector lid (fig. E).

Separate the disc (grey) from the valve body (grip on the edge of the disc) (fig. F).

Fit new disc (pass the tail through the central hole to the inside of the mask) (fig. G).
5.4 Replacing the inhalation valve discs

Remove the connector lid.

Remove the rubber valve seat by pulling it from the tip (fig. H).

Replace the disc (fig. J).

Put the valve seat back to the bottom of the valve body. Do not press too tight (the disc comes
immobilised) because the disc must be free to move.

The valve discs of the inner mask (fig. K) are replaced similarly. Make sure that the rubber edge
of the inner mask comes in the valve seat groove.
5.5 Replacing the speech diaphragm

Pull the head harness to the front of the mask (fig. L).

Fold the chin cup inside out, towards yourself (fig. M).

Remove the speech diaphragm (fig. N).

To make assembly easier, moisten the O-ring with water. Position the tip of the speech
diaphragm into the notch of the connector (fig. O–P) to prevent any leakage. Press the speech
diaphragm into place (fig. Q).

Fold the chin cup to its proper position (fig. R).
5.6 Cleaning

Remove the filter, valves, spectacle frame and speech diaphragm. Also eventual breathing hose.

Clean the facepiece and components with a damp cloth or sponge, using lukewarm water and
mild detergent (neutral, pH 6-8) (e.g. washing-up liquid). A brush can be used for stubborn dirt
(be careful not to scratch the visor).

Do not use solvents (e.g. alcohol, acetone, turpentine), hot water or bleaching agents
(perborate, percarbonate).
5.7 Disinfection
After cleaning, disinfect the inside/faceseal with a disinfection solution (e.g. Scott Trigene), rinse and
allow to dry. Finally, reassemble the mask.
