3.2 Disinfection
Masks should be disinfected after having been
cleaned as described above.
The disinfectant MSA AUER 90 or MSA Cleaner
Sanitizer is recommended. Information about the
concentration and time is contained in the
Instructions for Use of disinfectant. After disin-
fecting thoroughly, flush all components with
water, dry and reassemble (see table 5 for disin-
fection intervals).
4 Maintenance
Maintenance of the full face mask must be
performed by the maintenance technician (if there
is none, by the user). It includes the visual check,
the functioning and leak tests, as well as replacing
components.
4.1 Visual and Function Test
The visual and function test serves to identify
damaged components and functional disorders,
especially at the valves and harness. In case of
doubt about the functioning of a component, it
must be replaced immediately or the MSA AUER
customer service must be contacted.
Part of the visual test is to ensure adherence to the
test intervals according to Sect. 5.
4.2 Leak Test
The leak test is performed with the MSA AUER
leak test kit; its operation is described in the kit's
Instruction Manual.
The MSA AUER Customer Service should be con-
sulted prior to using leak test kits of other manu-
facturers.
4.3 Replacement of Components
Only MSA AUER spare parts must be used for
repair. After the replacement of components a
complete test must be done.

4.3.1 Replacing the Exhalation Valve Disc

To replace the exhalation valve disc, remove the
cover from the connector and unbutton the exha-
lation valve. After fitting a new exhalation valve,
the cover is reassembled. Make sure the cover

Unbutton the buckles of the neck strap. Turn the
flexible plastic harness that is in the hinge on the
lens ring way downward (faceblank will deform)
