Key tips
- ·Never disable a low-pressure/circuit-disconnect alarm while troubleshooting - silence it, don't disable it.
- ·Verify the O2 supply source and pressure before assuming an internal fault.
- ·Circuit type must match the patient population (adult/pediatric/neonatal) - a mismatched circuit invalidates delivered volumes.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Does not reach or hold set pressure
HighSymptoms: Therapy pressure low or unstable, cannot titrate, pressure-error alarm.
Root cause: Worn blower, an internal leak, a pressure-sensor fault, or a large mask / circuit leak.
Blower noisy / failing
MediumSymptoms: Loud or rattling blower, cannot meet flow demand, blower-error code.
Root cause: Worn blower bearings / motor.
Humidifier fault
MediumSymptoms: No or excessive humidity, water in the tubing, humidifier not heating, leak at the chamber.
Root cause: Humidifier heater plate, a chamber-seal fault, or a heated-tube fault.
Flow / pressure sensor drift
MediumSymptoms: Reported pressure or leak / AHI data implausible, fails verification.
Root cause: Sensor drift or a blocked sensing line.
Data / compliance download fault
LowSymptoms: SD card or modem data will not read, therapy data missing.
Root cause: SD card / slot fault or the wireless module.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily pre-use check: self-test, circuit integrity, alarm function
- ·Scheduled circuit and inspiratory filter replacement per manufacturer interval
- ·Flow and pressure sensor calibration verification
- ·Battery load test and runtime check
- ·Annual full PM and electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not hold set pressure
- Run the device's pressure-verification against a calibrated manometer with a test lung / cap.
- Check for internal leaks and a blocked sensing line.
- Confirm the mask / circuit is not the leak source.
- Replace the pressure sensor if it fails verification.
- Replace the blower if it cannot meet flow demand.
Symptom: Humidifier not working
- Confirm the heater plate warms and the chamber seats fully.
- Inspect the chamber seal and the heated-tube connector.
- Check the humidity setting and ambient conditions.
- Replace the chamber seal or heated tube.
- Replace the humidifier heater assembly if it will not heat.
