Do not expose any part of the mask
•
system or tubing to direct sunlight as it
may cause the product to deteriorate.
The valve membrane must be replaced
•
with a new valve membrane when the
mask is reused on another patient. This
part cannot be disinfected or sterilised.
If any visible deterioration of a mask
•
component is apparent (cracking,
crazing, tears etc), the mask
component should be discarded and
replaced.

EASSEMBLING THE
Make sure all parts of the mask system,
especially the valve membrane, are clean
and dry before reassembling. If the valve
membrane is damaged, distorted or torn,
replace it with a new valve membrane.
1 Insert the valve membrane into the
valve frame and gently push it into place
(Fig. E-1). Make sure it is seated evenly
and flatly around the rim of the valve
frame, as the membrane may produce a
noise while you are breathing out, if it is
fitted incorrectly.
2 Push the valve frame over the tabs of
the valve elbow until they lock together
(Fig. E-2). Make sure the valve frame
and valve elbow are securely connected
to each other.
3 Insert the swivel into the end of the
valve elbow and secure it with the
swivel clip (Fig. E-3).

EASSEMBLING THE
1 Check that the holes in the exhaust vent
are not obstructed. If they are
obstructed, replace the exhaust vent.
Push the exhaust vent onto the mask
frame so the small round bump on the
exhaust vent is on the outside of the
mask frame (Fig. F-1).
2 Twist the luer lock port caps onto the
mask ports (Fig. F-2).
3 Insert the valve into the mask frame.
Hold the mask frame and the inserted
valve firmly together.
4 To attach the elbow retainer, fit one
side of the elbow retainer against the
groove of the valve. While holding one
wing of the elbow retainer down
(Fig. F-3a), press the other wing down
until the elbow retainer clicks into place
(Fig. F-3b).
5 Rotate the elbow retainer to its original
V
ALVE
position (Fig. F-4).
6 Check that you have fitted the valve and
elbow retainer correctly by firmly pulling
the valve away from the frame. If the
valve is fitted correctly, it should not
separate from the frame.
If the valve comes away from the frame,
try refitting the elbow retainer as
described in Steps 4 and 5. If the valve
still comes away from the frame when
you pull on it, you may need to replace
the elbow retainer with a new one.
7 Fit the grooved edge of the mask
cushion to the mask frame. Fit the top
section first, then work your way around
the mask, pushing the cushion onto the
frame, ensuring a good seal has been
achieved.
Then push the cushion clip over the
cushion onto the mask frame, ensuring it
clicks into place in all locations (Fig. F-5).
8 Attach the forehead pads to the
forehead support by inserting the pad
M
ASK
plugs into the two holes on the back of
the forehead support (Fig F-6). Push the
pads firmly against the forehead support
to ensure that the pads fit securely into
the forehead support.
9 Connect the forehead support to the
mask frame. Slide the pivots into the
pivot slot on the mask frame (Fig. F-7).
