5.9 Cleaning
Remove the filter/filters, valves, spectacle frame, speech diaphragm and inner mask. 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).
5.10 Disinfection
After cleaning, disinfect the inside/faceseal with a disinfection solution (e.g. Scott Trigene), rinse and
allow to dry. Finally, reassemble the mask.
5.11 Storage
Do not keep the straps in constant strain (neck straps, temple straps, upper strap). The material
will deteriorate.
Store protected from direct sunlight, at -10...+50 °C and relative humidity (RH) under 75 %
(sealed filters RH max. 95 %). A properly stored, unused mask stays in good condition for a long
storage period.
After use, an opened filter must be sealed tightly if it is to be reused, but it must be replaced (at
the latest) within 6 months from the date of first use.
The components should not be more than 12 years old.
Before use, the mask must undergo a function test, see Table.
5.12 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).
5.13 Transport
Promask should be placed into its original packaging or a similar cardboard carton.
