Align the top edge of the liner with the top of the memory foam. The lower Quick Stick tabs of the liner will be able to reach the hard plastic on the bottom side of the mask. Even a small amount of adhesive contact to the hard plastic is adequate to hold the liner in place. Separating the Mask Cushion from the Headgear Frame may ease liner attachment*.
*Follow the manufacturer’s instructions if you choose to separate the Mask Cushion from the Headgear Frame. Be careful to not damage your mask. Although these parts are designed to be separated and reconnected, improper or repeated disassembly and reassembly could cause the parts to wear out or break.
