Promask + Pro
Turn the filter clockwise ¼ turn  The filter is tight only when the aligning marks (◄) are
opposite each other and the openings of the splash guards face backwards.
4.2 When needed, connect the spectacles to the inner mask and adjust their position.
4.3 A sweat band is recommended to control excessive hair.
4.4 Loosen the head harness straps.
4.5 Locate the chin pocket of the mask properly on the chin and pull the head harness over the
head.
4.6 Check that the chin is in the chin pocket. Tighten the straps. Start with neck straps, pull
backwards (not outwards). Then adjust the temple straps and finally the upper strap. The cradle/net
lies centered on the back of the head.
Note! Check that the faceseal touches the skin all around, especially under the chin pocket. Try
moving the mask sideways to verify that there is no slippage.
4.7 Check tightness of the mask (two alternative methods):
1) Cover the exhalation opening of the mask with your hand. Exhale gently to create overpressure.
There must be no leakage between the face and the faceseal.
2) 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 and filter, or use another
size of the mask.
5. Maintenance and storage
Inspect the product regularly for damage and replace where necessary.
5.1 Test for function and leak-tightness
If components have been replaced (visor, valve discs or speech diaphragm), a test for function and
leak-tightness must be carried out with an appropriate test device (e.g. Pro-Tester, code 5141080).
The test is also done in case of a mask stored unused for a longer period.
Check also that the faceblank has maintained its shape, the head harness is reasonably elastic, the
visor and the faceseal are undamaged, and that the valve discs and the speech diaphragm's O-ring
are good and well in position. Damage must be repaired.
5.2 Replacing the visor
The visor is available in polycarbonate or polycarbonate with a chemical-resistant and scratch-proof
coating. The material code is found at the left edge of the visor. Replace visor if damaged, dirty or
scratched.
Material code is shown by an arrow:
1 (not in use)
2 (not in use)
3 hard coated polycarbonate (HC)
F polycarbonate (PC)
