3 To attach the elbow retainer, fit one side of the elbow retainer against the
groove of the elbow. While holding one wing of the elbow retainer down
(D-3a), press the other wing down until it clicks into place (D-3b).
4 Rotate the elbow retainer to its original position (D-4).
5 Check that you have fitted the elbow and elbow retainer correctly by firmly
pulling the elbow away from the frame. If the elbow is fitted correctly, it
should not separate from the frame.
If the elbow comes away from the frame, try refitting the elbow retainer as
described in Steps 3 and 4. If the elbow still comes away from the frame
when you pull on it, you may need to replace the elbow retainer.
6 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 and onto the mask frame,
ensuring it clicks into place in all locations (D-5).
7 Attach the forehead pads to the forehead support by inserting the pad plugs
into the two holes on the back of the forehead support (D-6). Push the pads
firmly against the forehead support to ensure that the pads fit securely into
the forehead support.
8 Connect the forehead support to the mask frame. Slide the pivots into the
pivot slot on the mask frame (D-7). Depress the forehead support tab and
move it into any of the tab positions.
9 Insert the headgear clips into the slots on the mask frame. The headgear
label should face outward and be near the patient’s neck when fitted.
Note: The Emergency Release Cord must be attached to one of the bottom
headgear straps in order to function correctly.
