Cover the exhalation opening with your hand. Exhale gently to create overpressure.
There must be no leakage between the face and the face seal.

Cover the filter openings with your hand. Inhale to make the mask press onto your
face.
If you fail to get a tight fit (=potential leakage), adjust the head harness or use another
size of the mask.
5. Maintenance and storage
Use only original spare parts. After use the mask must be checked, cleaned and disinfected.
Replace damaged parts. Valve discs must be replaced every other year at the latest.
D
Replacing the exhalation valve disc

Close the cover.
E
Replacing the inhalation valve discs

Check that the discs remain flat.
Replacing the head harness

place.
Cleaning
Remove
the filters, cover and valves.
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.
Do not use
solvents (e.g. alcohol, acetone, turpentine), hot water or bleaching agents
(perborate, percarbonate).
Disinfection
After cleaning, disinfect the the inside/face seal with a disinfection solution (e.g. Scott Trigene),
rinse and let it dry (max +50 ºC). Finally, reassemble the mask.
Storage
Storage protected from direct sunlight, at -10...+50 °C and relative humidity (RH) under 75
% (sealed filters RH max. 95 %).
The components should not be more than 5 years old.
After use, an opened filter must be sealed tightly if it is to be reused, but it must be
replaced within 6 months at the latest.
Disposal
Masks (without filters) are coarse waste. A very contaminated mask as well as used filters
are special refuse and shall be disposed of according to the filtered substances (gases or
particles).
