Use, and Donning
See Instructions for Use of the filter and blower device to be used.
Check before use
intactness of facepiece, rubber parts and visor
head harness condition and elasticity
that speech diaphragm is in place
that exhalation valve is in place and that its cover is properly fastened
that inh. and exh. valves function properly
that the filter is correct for the intended use (filter type and class)
that storage period of the filter has not been exceeded
filter condition and intactness. Shake the filter to ensure that there are no loose components/
contents. The filter shall be replaced if it has been exposed to strong press or impact. It may be
damaged, also by a fall on a hard surface, also when attached to a mask / blower device.
With a blower device
Check adequate air flow (see Instructions for Use of the blower unit).
Fitting of the filter

:
Align the bayonets on the mask with the slots on the filter and locate the filter.
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.
When needed, connect the spectacles to the inner mask and adjust their position.
A sweat band is recommended to control excessive hair.
Loosen the head harness straps.
Locate the chin pocket of the mask properly on the chin and pull the head harness over the head.
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.
Check tightness of the mask (two alternative methods): 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.
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.
Maintenance and storage
Inspect the product regularly for damage and replace where necessary.
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.
