Cleaning the Mask at Home
The mask and headgear should be cleaned by handwashing.•
The headgear may be washed without removing the headgear clips.•
WARNING
Do not use aromatic-based solutions or scented oils (eg, eucalyptus
or essential oils), bleach, alcohol or products that smell strongly (eg,
citrus) to clean any of the mask components. Residual vapors from these
solutions can be inhaled if not rinsed thoroughly.They may also damage
the mask, causing cracks.
CAUTION
If any visible deterioration of a mask component is apparent (cracking,•
crazing, tears etc.), the mask component should be discarded and
replaced.
Avoid connecting flexible PVC products (eg, PVC tubing) directly•
to any part of this mask. Flexible PVC contains elements that can
be detrimental to the materials of the mask, and may cause the
components to crack or break.
Daily/After Each Use
To optimize the mask seal, facial oils should be removed from the cushion
after use.
Handwash the mask by gently rubbing in warm (86°F/30°C) water using mild
soap.
If the vent requires cleaning use a soft bristle brush.
Rinse all components well with drinking quality water and allow them to air
dry out of direct sunlight. Do not soak the mask.

Troubleshooting
Possible reason Solution
Mask is uncomfortable
Headgear straps are too tight. Adjust the straps evenly. The forehead support
“anchors” your mask and should sit firmly on
your forehead.
Cushion incorrectly inflated. With the air turned off, adjust the straps so that
you can insert two fingers between your cheek
and the lower headgear strap.
Mask is too noisy
Cushion clip is not inserted
correctly.
Check that the cushion clip is correctly inserted
into the cushion, and that the cushion is
correctly clipped to the frame.
Ports cap or elbow incorrectly
inserted.
Check the the ports cap and elbow are correctly
inserted.
Vents are blocked or partially
blocked.
Clean vents according to instructions in
“Cleaning the Mask at Home”.
Air leaking around the face
Mask not positioned correctly. Reposition the mask upon the face.
Air leaking around the bridge of the
nose.
Wind the dial in.
Air leaking around the top of the lip. Wind the dial out.
The mask does not fit properly
Cushion could be the wrong size. Talk to your clinician.
Mask is incorrectly assembled. Reassemble the mask according to the
instructions in “Reassembly”.
Cushion may be dirty. Clean cushion according to instructions in
“Cleaning the Mask at Home”.

Before Using the Mask
WARNINGS
The vent holes must be kept clear.•
Follow all precautions when using supplemental oxygen.•
Oxygen flow must be turned off when the flow generator is not operating,•
so that unused oxygen does not accumulate within the flow generator
enclosure and create a risk of fire.
At a fixed flow rate of supplemental oxygen flow, the inhaled oxygen•
concentration varies, depending on the pressure settings, patient breathing
pattern, mask, point of application and leak rate.
The technical specifications of the mask are provided for your clinician to•
check that they are compatible with the flow generator. If used outside
specification or if used with incompatible devices, the seal and comfort of
the mask may not be effective, optimum therapy may not be achieved, and
leak, or variation in the rate of leak, may affect the flow generator function.
Discontinue using the mask if you have ANY adverse reaction to the use of•
the mask, and consult your physician or sleep therapist.
Using a mask may cause tooth, gum or jaw soreness or aggravate an•
existing dental condition. If symptoms occur, consult your physician or
dentist.
As with all masks, some rebreathing may occur at low CPAP pressures.•
Refer to your flow generator manual for details on settings and operational•
information.
Remove all packaging before using the mask.•
