Preconditions for use with respiratory filters
Together with a respiratory filter, the full face mask forms a filtering
device. Observe the following preconditions if the full face mask is
used as a filtering device:
– The ambient conditions (particularly the types and concentrations
of contaminants) must be known. Use corresponding respiratory
filters. If used for an unknown contaminant, only use self-
contained or air line breathing apparatuses.
– Only use filtering devices if the air does not directly endanger the
health or life of the user.
– It must be ensured that the ambient atmosphere cannot change to
the worse.
– Do not use filtering devices if there is suspicion of contaminants
with low warning properties (low-odour, tasteless, no irritation of
eyes and airways). A decreasing protective effect of the filtering
device cannot be determined in this case.
– Do not use filtering devices for entering unventilated tanks, mines,
canals, etc.
– Do not use filtering devices in oxygen-enriched atmospheres.
– The oxygen content of the ambient air must not fall below the
following limit values:
 at least 17 Vol% oxygen in all European countries except the
Netherlands, Belgium and the UK
 at least 19 Vol% oxygen in the Netherlands, Belgium, the UK,
Australia and New Zealand
 In other countries, observe the applicable national
regulations.

 Remove the carrying strap.
 Pull the harness apart, then put your
chin into the chin cup of the mask body.

draw it backwards.
 Adjust the full face mask.
 Pull the straps until evenly tightened;
first the neck straps (1), then the
temple straps (2), finally the front strap
(3).
 Don the helmet, close the chin strap
and check that the helmet fits firmly on
the head. Tighten the chin strap if
necessary.
 Seal the connector with your hand and inhale until a negative
pressure is created.
 Hold your breath for a moment.
The negative pressure should remain. Otherwise, adjust the
straps.
 Repeat the last 2 steps twice.
 Seal the connector and exhale vigorously. The exhaled air must
be able to escape without obstruction. If not, see "Visual
inspection of the exhalation valve" on Page 17.
