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.  
Weekly

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.
