EASSEMBLING THE
ATTENTION
It is important to follow the instructions
detailed in this section. Any deviation
from the specified order of assembly
could affect the functioning of your mask.
Reassembling the entire mask involves two
stages:
1. Valve Reassembly
2. Mask Reassembly
V R
ALVE EASSEMBLY
See section E on the illustrations sheet.
Note:
This stage must be completed before
Mask Reassembly.
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).
4 Set the assembled valve (Fig. E-4) aside
for use in the following stage.

ASK EASSEMBLY
See section F on the illustrations sheet.

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).
CAUTION
The exhaust vent must be correctly
inserted into the mask frame to
prevent leakage. Poor sealing may
reduce pressure and affect therapy.
2 Twist the luer lock port caps onto the
mask ports (Fig. F-2).
3 Insert the assembled valve into the mask
frame (Fig. F-3).
Note:
The valve must be assembled
(as depicted in Figure E-4), before it is
inserted into the mask frame.
4 Hold the mask frame and the inserted
valve firmly together.
5 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-4a), press the other wing down
until the elbow retainer clicks into place
(Fig. F-4b).
6 Rotate the elbow retainer to its original
position (Fig. F-5).
7 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.
