CAUTION
• If any visible deterioration of a mask component is apparent (cracking,
crazing, tears etc.), the mask component should be discarded and
replaced.
• Avoid connecting flexible PVC products (eg, PVC tubing) directly
to any part of this mask. Flexible PVC contains elements that can
be detrimental to the materials of the mask, and may cause the
components to crack or break.
Reprocessing the Mask between Patients
Only Sleep Lab Mask (SLM) variants of the mask are intended for
multi-patient re-use. When using between patients, these masks must be
reprocessed according to cleaning and disinfection instructions available on
ResMed.com/downloads/masks.

into the cushion, and that the cushion is
correctly clipped to the frame.
Check the the ports cap and elbow are correctly
inserted.
