Thermal disinfection procedure
1. Disassembly
1. Disassemble the mask according to the instructions in the User Guide.
2. Additionally:
• Firmly pull the elbow clip away from the elbow body. (Fig a.)
• Pull the elbow ring out of the frame. (Fig b.)
• Firmly slide the frame magnetic clip from the frame connector. Repeat on the other side. (Fig c.)
2. Cleaning
1. Make a solution of a mild alkaline, anionic detergent and water1as per manufacturer’s instructions. ResMed has validated the following:
• Alconox 1% concentration (10 g/L) 86-131°F (30-55°C)
2. Soak all mask components for 5 to 10 minutes. Ensure there are no air bubbles.
3. After the soaking time, while keeping the components in the solution, clean the inside and outside with a soft bristle brush as follows. Pay particular attention to the crevices and cavities.
• Elbow body 30 seconds brushing
• Elbow clip / elbow ring / frame magnetic clips 10 seconds brushing
• Cushion / frame2/ headgear 1 minute brushing
4. Rinse the components as follows under running water1at 68-140°F (20-60°C) directly contacting all surfaces.
• Cushion / frame / frame magnetic clips /
elbow body / elbow clip / elbow ring 30-60 seconds rinsing
• Headgear 1 minute rinsing, while squeezing repeatedly
3. Inspection and drying
1. Inspect and if required, repeat all steps in section [2. Cleaning] until visually clean.3
2. Squeeze the headgear to remove excess water.
3. Allow the mask components to air dry out of direct sunlight.4
4. Disinfection
1. Soak the mask components in a hot water1bath using one of the following temperature-time combinations. Ensure there are no air bubbles.
• 167°F (75°C) for 30 minutes OR
• 194-199°F (90-93°C) for 1 to 10 minutes
2. Squeeze the headgear to remove excess water.
3. Allow the components to air dry out of direct sunlight.
5. 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.
6. Reassembly
1. Push the elbow clip onto the elbow body until it clicks into place.
2. Insert the elbow ring into the top of the frame.
3. Firmly slide the frame magnetic clip onto the frame connector. Repeat on the other side.
4. Reassemble the mask according to the instructions in the User Guide.
7. Storage and transportation For storage and transportation details, check the User Guide.
1For all cleaning, rinsing and disinfection steps, use drinking quality water.
2A soft bristle tube/bottle brush is required to clean the inside of the frame.
3Failure to clean the mask component as indicated may result in inadequate disinfection.
4Drying is not required if thermal disinfection is continued immediately.
