4.2 Exhalation system
The sleeve at the end of the creased hose has
a diameter of 19.5 mm and fits over a 22 mm
standard cone. Place the sleeve on the exha-
lation system.
The exhalation system allows you to breathe
through the nose or mouth if the unit malfunc-
tions. Full facial masks must also be equipped
with a safety valve. Remove the mask as soon
as possible. First check whether a power fail-
ure has occurred.
Please observe the operating instructions for
your exhalation system
4.3 Fitting mask

(if provided).
2. Connect the headgear to the mask.

the mask only results in low pressure to
prevent causing pressure points on the
face.
Please refer to the operating instructions for
the relevant mask for further procedure.
