Setting up your device
WARNING
Do not use any additives in the humidifier tub (eg, scented oils or perfumes). These may reduce
humidification output and/or cause deterioration of the tub materials.
CAUTION
Use only ResMed parts (eg air inlet filter, power supplies), masks and accessories with the machine.
Non ResMed parts may reduce the effectiveness of the treatment, may result in excess carbon
dioxide rebreathing and/or damage the machine. For compatibility information, refer to
ResMed.com for more information.
When using the humidifier tub:
•Always place the device on a level surface, lower than your head, to prevent the mask and air
tubing from filling with water.
•Do not overfill the humidifier tub as water may enter the device and air tubing.
•Do not fill the humidifier tub with hot water as this could lead to excessive air temperature at the
mask. Ensure the water is cooled to room temperature before filling the humidifier tub.
•Do not place the device on its side while the humidifier is attached as water might get into the
device and reduce motor life.
When setting up the AirSense system:
•Do not place the power supply where it can be bumped, stepped on, or where someone is likely
to trip over the power cord.
•Do not block the air tubing and/or air inlet of the device while in operation as this could lead to
overheating of the device.
•Keep the area around the device dry, clean and clear of anything (eg, clothes or bedding) that
could block the air inlet or cover the power supply unit.
•Ensure the system is correctly setup. Incorrect system setup may result in incorrect mask
pressure reading.
When using a mask:
•Use only vented masks recommended by ResMed or by the prescribing doctor with this device.
•Fitting the mask without the device blowing air can result in rebreathing of exhaled air.
•Make sure that the mask vent holes are kept clear and unblocked to maintain the flow of fresh air
into the mask.

6
To set up the device:
1. Place the device on a stable level surface.
2. Connect the power cord into the power inlet at the rear of the device. Connect one end of the power
cord into the AC adaptor and the other end into the power outlet.
3. Connect the air tubing firmly to the outlet connector at the rear of the device.
4. Open the humidifier tub and fill it with distilled water under room temperature up to the maximum
water level mark. The humidifier tub must be removed from the device before adding water. The
humidifier tub has a maximum capacity of 380 mL.
5. Close the humidifier tub and insert it into the side of the device.
6. Connect the free end of the air tubing firmly onto the assembled mask.
See the mask user guide for detailed information.
Recommended masks for use with this device are listed on Resmed.com
Notes:
•Do not insert any USB cable into the AirSense 11 device or attempt to plug the AC adaptor into a USB
device. This may cause damage to the AirSense 11 device or USB device.
•The electrical connector end of the heated air tubing is only compatible with the air outlet at the device
end and should not be fitted to the mask.
•Do not use electrically conductive or anti-static air tubing.

About the heated tubing
The ClimateLineAir 11 is a heated breathing tube that delivers air to a compatible mask. When used with
the device humidifier tub, ClimateLineAir 11 heated air tubing allows you to use the Climate Control
feature.
Note: Not all types of air tubing are available in all regions.
Climate Control
Climate Control is designed to make therapy more comfortable by enabling constant temperature and
maintaining humidity.
This feature:
•delivers comfortable humidity level and temperature during therapy
•maintains the set temperature and relative humidity during sleep to prevent dryness in the nose and
mouth
•can be set to either Auto or Manual
•is only available when both the ClimateLineAir 11 and HumidAir tub are attached.
Climate Control - Auto setting
Auto is the recommended and default setting. It is designed to make therapy as easy as possible so there
is no need to change the temperature or humidity settings.
•Sets the tube temperature to Auto (80ºF/27ºC). If the air in the mask is too warm or too cold, you can
adjust the tube temperature to anywhere from 60 to 86ºF (16 to 30ºC) or turn it off completely
•Adjusts the humidifier output to maintain a constant, comfortable humidity level of 85% relative
humidity
•Protects against rainout (water droplets in the heated air tubing and mask).
Climate Control - Manual setting
Manual is designed to offer more flexibility and control over settings and offers the following:
•Temperature and humidity can be adjusted to find the most comfortable setting
•Temperature and humidity level can be set independently
•Rainout protection is not guaranteed. If rainout does occur, first try increasing the tube temperature
•If the air temperature becomes too warm and rainout continues, try decreasing the humidity.
Note: If Climate Control is set to Manual, the Auto Tube Temperature setting is not available.
Humidity Level
The humidifier moistens the air and is designed to make therapy more comfortable.
•If you are getting a dry nose or mouth, turn up the humidity
•If you are getting any moisture in your mask, turn down the humidity.
•You can set the Humidity Level to Off or between 1 and 8, where 1 is the lowest humidity setting, and
8 is the highest humidity setting.
To update the setting for Tube Temperature, Climate Control, or Humidity Level, tap MY OPTIONS
from the Home screen, go down the list of options, and select the setting.
Note: Tube Temp Auto setting is only relevant when using the Climate Control Auto setting. If Climate
Control is set to Manual, Auto set temperature is not a valid selection.
