ResMed AirFit N20 User Manual page 8

Fitting your mask
1. Twist and pull both magnetic clips away from the frame.
2. With both lower headgear straps released, hold the mask
against your face and pull the headgear over your head.
Headgear check:
Ensure that the ResMed logo on the headgear is facing
outwards and is upright when the headgear is put on.
3. Bring the lower straps below your ears, and attach the
magnetic clip to the frame.
4. Undo the fastening tabs on the upper headgear straps.
Adjust the straps evenly until the mask sits comfortably
just over the nose. Reattach the fastening tabs.
5. Undo the fastening tabs on the lower headgear straps.
Adjust the straps evenly until the mask is stable. Reattach
the fastening tabs.
6. Connect the device air tubing to the short tube. Attach the
elbow to the mask by pressing the side buttons and
pushing the elbow into the mask, ensuring it clicks in on
both sides.
7. Your mask and headgear should be positioned as shown in
the illustration.
Adjusting your mask
If necessary, slightly adjust the position of the mask for the
most comfortable fit. Ensure that the headgear is not twisted
and for the AirFit N20 the cushion is not creased.
1. Turn on your device so that it is blowing air.
Adjustment tips:
−
To resolve any leaks at the upper part of the mask,
adjust the upper headgear straps. For the lower part,
adjust the lower headgear straps. Adjust only enough
for a comfortable seal.
−
The upper strap adjustment is the key to seal and
comfort.
−
Do not overtighten the lower straps because they
mainly serve to keep the cushion in position.
Removing your mask
1. Twist and pull both magnetic clips away from the frame.
2. Pull the mask away from your face and back over your
head.
Disassembling your mask for cleaning
If the mask is connected to your device, disconnect the device
air tubing from the short tube.
1. Undo the fastening tabs on the upper headgear straps and
pull them from the frame. Keep the magnetic clips
attached to the lower headgear straps.
2. Remove the elbow from the mask by pressing the side
button and pulling the elbow away.
3. Hold the frame by placing your thumb over the side slot.
Pull the cushion away from the frame.
Reassembling your mask
1. Push the cushion into the frame. The frame has a shape
that allows you to insert the cushion only one way.
2. With the ResMed logo on the headgear facing outside and
upright, thread the upper headgear straps into the frame
slots from the inside. Fold them over to secure.
