times with fresh water.
Inspection / Drying 1. Inspect and if required, repeat washing until visually clean.
2. Allow the mask components to air dry out of direct sunlight.
Disinfection 1. Using a hot water disinfection system, soak the disinfectable mask components using a temperature-time combination:
• AirFit F20 cushion/elbow/frame: 167°F (75°C) for 30 minutes; 176°F (80°C) for 10 minutes; 194°F (90°C) for 1 minute;
• Headgear:
2. On completion, remove the mask components from the hot water disinfection system.
3. Allow the mask components to air dry out of direct sunlight.
Inspection
Perform a visual inspection of each mask component. If any visible deterioration of a mask component is apparent (cracking, crazing, tears etc), the mask component should be discarded and replaced. Slight
discoloration of the silicone components may occur and is acceptable.
Reassembly Reassemble the mask according to the instructions in the User Guide.
Packaging and storage
