MAINTENANCE

:
1. REPLACING THE VISOR
If the visor is damaged or the field of vision reduced, it must be replaced. The two
screws in the visor frame can be loosened with a screwdriver. The visor frame and
the visor can then be removed. The new original ICAN-visor should be secured in
the silikone frame so that the two centre markings on the visor are located exactly
opposite the centre markings on the silicone frame. The two-piece visor frame
should then be positioned correctly and screwed firmly in place. After replacement
of the visor, a leakage test must be carried out using a suitable leakage analyser.

2. REPLACING THE EXHALATION VALVE MEMBRANE
The exhalation valve cover can be removed by gently pulling it out. If the
membrane is deformed, split or otherwise damaged, it must be replaced. Remove
the membrane by taking hold of the edge and pulling outwards. Fit a new original
ICAN-membrane by pressing it down fully onto the valve seat's connection piece.
Check that the valve seat is clean and undamaged. If the valve seat is damaged,
the entire valve housing must be replaced. After replacing the exhalation valve
membrane, a leakage test must be carried out using a suitable leakage analyser.

3. REPLACING THE INHALATION VALVE MEMBRANE AND VALVE SEAT
If the inhalation valve membrane is deformed, split or otherwise damaged, it must
be replaced. The membrane can be replaced by removing the rubber valve seat,
which also acts as a packing. A new original ICAN-membrane should then be fitted
onto the inlet valve pin, and the valve seat pressed, with the inhalation valve
membrane first, through the valve housing's opening. The valve seat is pressed
through until it falls into place. Make sure that the membrane is not restricted in its
movement. After replacing the inhalation valve membrane and valve seat, a
leakage test must be carried out using a suitable leakage analyser.

4. REPLACING THE CONTROL VALVE MEMBRANE
If the control valve membrane is deformed, split or otherwise damaged, it must be
replaced. The membranes can be removed by taking hold of the edges and carefully
pulling them out of the valve seat. New original ICAN-membranes can
