4.1 Intervals
Daily
Clean the mask in warm water to remove all
residues. To do this the mask can be
disassembled as described in section 3.12
" Disassembling/assembling the mask". Use
a mild cleaning agent (e.g. dishwasher
detergent). After cleaning, rinse all parts
carefully with clean water.
Caution!
• For patients with a weakened immune sys-
tem or a special medical history, daily dis-
infecting or sterilization of the mask
components may be necessary. In this case,
please consult your doctor.
• Please take great care when cleaning and
disinfecting the contact surfaces between
the mask frame and the retaining ring.
Residues on these surfaces can reduce the
