Checking

WARNING
• Discontinue use and contact an appropriate care professional if any of the following occur:
• device does not perform as usual
• device is making unusual sounds
• device is damaged
• If using a bacterial/viral filter, regularly check it for signs of moisture or other contaminants,
particularly during nebulization or humidification. Failure to do so could result in increased
breathing resistance or affect the delivery of the therapeutic pressure.
CAUTION
If any visible deterioration of a system component is apparent (cracking, discoloration, tears etc.),
the component should be discarded and replaced.
Regularly check the humidifier tub, air tubing, and air filter for any damage.
1. Check the humidifier tub:
• Replace it if it is leaking or has become cracked, cloudy, or pitted.
• Replace it if the seal is cracked or torn.
• Remove any white powder deposits using a solution of 1 part household vinegar to 9 parts water.
Rinse with clean water.
2. Check the air tubing and replace it if there are any holes, tears, or cracks.
3. Check the air filter and replace it every six months. Replace it more often if there are any holes or
blockages by dirt or dust.

Replacing the air filter

1. Open the air filter cover and remove the old air filter.
2. Place a new air filter onto the air filter cover and then close the cover. Make sure the air filter and air
filter cover are fitted at all times to prevent water and dust from entering the device.
Note: The air filter is not washable or reusable.

Reassembling

When the components are dry, you can reassemble the parts.
To reassemble the AirSense 11 system:
1. Hold the outlet connector with the seal pointing to the left and the clip pointing forward.

3. Check the outlet connector is inserted correctly.
4. Connect the air tubing firmly to the air outlet located on the rear of the device.
5. Open the humidifier tub and fill it with drinking quality water (potable) under room temperature up to
the maximum water level mark.
6. Close the humidifier tub and insert it into the side of the device.
7. Connect the free end of the air tubing firmly onto the assembled mask.
