Disassembly steps
1.
Remove the headgear by slightly twisting each headgear arm
and pulling away from the node on the mask cushion.

Peel the mask cushion away from the swivel ring.
Note:
The headgear straps are not intended to be disassembled and can
be washed together.
Reassembly
Refer to the reassembly illustrations in this user guide. A diagram
showing the names of parts can be found in the Mask Components
diagram near the beginning of this guide.
Reassembly steps
1.
Using your forefinger and thumb to stretch the inside of the
mask cushion, insert the swivel ring into the mask cushion.
2.
Allow the mask cushion to sit in the groove on the swivel ring.
The mask cushion is correctly positioned when it is located in the
swivel ring groove with no gaps. Ensure that the swivel ring is
not pushed all the way into the mask cushion.
3.
Rotate the elbow to ensure it moves freely in the swivel ring.
4.
Thread the top strap through the top buckle with the notches
facing up.
5.
Hold the headgear arm with the opening facing you. Latch the
headgear arm onto the node on the mask cushion. Make sure
that the text on the headgear lines up with the text on the mask
cushion.
6.
Repeat the previous step with the other headgear arm. Ensure
that the headgear straps are not twisted.
7.
Thread the fabric back strap through each side of the headgear,
then fold over to secure. Ensure that the fastener is on the
outside with the ResMed logo facing out.
