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.
