3 Operation
Fig. A-E: see enclosed leaflet.
3.1 Adjust forehead support (Fig. A)
Fine adjustment
Squeeze the upper side tabs of the coarse
adjustment component inwards. Fit the fine
adjustment component into one of the three
notches.
To change the height of the forehead
cushion, i.e. the fine adjustment (by approx.
1 cm), turn the fine adjustment component
through 180°. Then position it as described
above.
Coarse adjustment
Squeeze the lower side tabs of the coarse
adjustment component inwards. Place it in
one of the slots in the mask frame.
3.2 Putting on the mask
1. Unhook one of the lower headgear clips
from the mask.
2. Guide the headgear over your head and
hook the headgear clips back onto the
strap.
3. Adjust the upper and lower headgear
straps so that the mask sits firmly, but not
too tightly, on your face.
HEADstrap only:
The HEADstrap headgear provides the
following options for you to do this (see
also "Overview" on the attached leaf-
let):
– coarse adjustments: slot "a" or "b" of the
headgear.
– fine adjustments: four hook-and-loop
straps."
4. If necessary, re-adjust the forehead
support.
3.3 Exhaled air system (Fig. E)
vented variants
vented variants (all mask components are
transparent) have a so-called integrated
exhaled air system: the retaining ring and
mask frame are shaped in such a way that a
gap is formed between these parts. Through
this gap the exhaled air can escape. The
special geometry of the parts guarantees that
when putting on the retaining ring the gap
cannot be closed. Do not connect an
external exhaled air system, otherwise the
therapy pressure will not be reached.
non vented variants
non vented variants (retaining ring, elbow and
rotating sleeve in blue) have no exhaled air
system. It is essential to connect an external
exhaled air system. Otherwise there is a risk of
reinhaling CO and of asphyxia.
2
Follow the instructions for use of your
exhaled air system.
3.4 Connecting the mask to the
therapy device (Fig. E)
Push the hose of your therapy device onto the
rotating sleeve (vented variants) or onto your
external exhaled air system (non vented
variants). Ensure that the connection to the
hose is secure and airtight. The connection
must not be loosened by the therapy pressure.
If you want to detach the mask temporarily
from the hose, pull the rotating sleeve off the
elbow.
3.5 Gel-filled mask components
On JOYCE GEL vented and JOYCE GEL
non vented, the forehead cushion and the
mask cushion are gel-filled as standard. Gel
forehead cushions and gel mask cushions are
also available as replacement parts for other
JOYCE variants.
Caution!
Gel-filled mask components are highly sensi-
tive components. Always handle them with
care to prevent deformation and damage.
