Assembling the Cushion and Flap
Remove the Gel cushion by detaching the comfort flap with its
integrated retaining ring from the faceplate. Do this by pressing on the
faceplate tabs at the bottom of the mask. Clean or discard the cushion
as necessary.
First, place the Gel cushion onto the faceplate (Figure 13). Then, put
the Comfort Flap over the Gel cushion and push the retaining ring
onto the faceplate until the connection tabs click into place. Gently tug
on the cushion to make sure all of the parts are securely in place.
