Servicing
Your SULLIVAN ® Comfort™ is designed to give years of trouble-free operation.
It is not necessary to send your unit away for regular servicing provided you
follow the recommendations in section 9, Cleaning and maintenance.
Should you feel that your unit is not performing properly, check section 11,
Troubleshooting. If there is still a problem, contact your equipment supplier or
sleep clinic.
Inspection and repair should only be performed by an authorized service agent.
Make sure you return your mask and air tubing with your flow generator and
advise your prescribed pressures.
