Use
Handle the respiratory filter with care: do not knock or drop the fil-
ter!
Air from the filter can be warm and the filter housing may become
very hot during use. This shows that the filter is functioning correct-
ly.
 Only open the bag immediately before use. Do not bore into
the respiratory filter with sharp objects.
 The respiratory filter must be tightly connected to the fa-
cepiece.
Filters and facepieces are only to be used according to the
combinations listed (see Table 1).
Inserting two respiratory filters (unencapsulated particle filters
in combination with the gas filter, particle filters, gas filters or
combination filters)
(see Figure A)
 Position respiratory filter (1) – line markings opposite! – and
lock to the stop (2) by screwing the respiratory filter downward
until the stop is noticeable.
The respiratory filter is removed in the reverse way.
WARNING
!
Do not insert bayonet connector on one side only! Do not
jam respiratory filter when locking!
Attaching pad particle filter (to the gas filter)
(see Figure B)
 Insert pad particle filter into the pad cap (labelling visible from
outside) and snap into place on all sides (1).
 Click pad cap with inserted pad particle filter to the gas filter (2).
Make sure that the fit of the pad particle filter remains un-
changed.
Service life
A general guide to service life cannot be given, as the service life
depends very strongly on the ambient conditions, e.g. nature and
concentration of the contaminant, air requirement of the user, hu-
midity and temperature.
– Gas filters must be replaced at the latest when the user notices
penetration of the filter (odour, taste or irritations).
– Particle filters must be replaced if the breathing resistance in-
creases significantly.
– Combination filters must be replaced when the apparatus has
been penetrated and/or when breathing resistance is in-
creased.
