SERVICE LIFE |
The service life of the F20 mask system is dependent on the intensity of usage, maintenance, and environmental conditions to which the mask is used or stored. As this mask system and its components are modular in nature, it is recommended that the user maintain and inspect it on a regular basis, and replace the mask system or any components if deemed necessary or according to the ‘visual criteria for product inspection’ in the ‘Cleaning your mask at home’ section of this guide. Refer to the ‘Mask components’ section of this guide for information of how to order replacement parts. |
MASK SETTING OPTION |
For AirSense, AirCurve or S9: Select 'Full Face'. For other devices: Select 'MIR FULL' (if available), otherwise select 'FULL FACE' as the mask option. |
