SECTION 2—FITTING THE MASK
6
3.
Check that the valve functions properly by sealing off the cushion 
facial opening. The valve flap should cover and seal the large opening 
in the mask swivel. 
4.
Turn the flow generator Off. The flap should return to a straight 
position and not be blocking the large opening in the mask swivel.
 
WARNING
DO NOT place the mask on your face unless the PAP machine is 
turned On. Otherwise, injury may occur.
Fitting the Mask
NOTE: For this procedure, refer to SECTION D in the supplemental sheet.
1.
Before fitting the mask, unfasten one or both of the headgear clips 
from the mask frame (D-1).
2.
Place the mask on the face with the headgear straps behind the head 
(D-2).
3.
Fit the mask loosely over the nose and mouth with minimal pressure.
4.
Reattach both headgear clips to the mask frame (D-2).
5.
Adjust the mask as follows:
A. Lift the forehead lever to the unlocked position (D-3).
B. Slide the forehead support up or down until it contacts the 
forehead and the upper portion of the cushion lightly touches the 
bridge of the nose (D-3).
C. Lower the forehead lever to lock the forehead support in the 
desired position (D-4).
 
WARNING
DO NOT pull the straps too tight. This can cause skin irritation and 
may deform the cushion causing a leak. If the mask and headgear are 
adjusted correctly and a problem persists, contact your health care 
professional.
6.
Adjust the strap length as needed using the hook and loop fasteners 
(D-5 and D-6).
NOTE: If a leak occurs, adjust the forehead support. If this does not work, tighten 
or loosen the headgear straps by readjusting the hook-and-loop fasteners.
NOTE: Proper mask fit should allow full contact of the cushion without excessive 
pressure on the face.
