Please contact your equipment provider if you're having any problems with your CPAP machine.
Distilled water is recommended in your humidifier tub.
The machine will work without water in the tub but you'll need to insert the tub into the machine and turn humidification off in the My Options menu on your AirSenseTM 10 or AirCurveTM 10 machine. If you don't want to use the humidifier, you'll need to insert a side cover into the device.
Icons are displayed on the machine screen to indicate when the humidifier is heating up or cooling down. The Sleep Report option on your AirSenseTM 10 or AirCurveTM 10 machine indicates that your humidifier is working properly with a smiley face icon. See your user guide for a detailed list of icons and their descriptions.
