Key tips
- ·Don't extend filter/tubing replacement intervals to save cost - this is an infection-control issue, not just a performance one.
- ·Flow accuracy drift is often the earliest sign of a failing sensor, well before an outright alarm.
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.
Low O2 concentration alarm
HighSymptoms: Oxygen-concentration alarm, delivered O2 below spec at flow.
Root cause: Aged sieve beds (molecular sieve), a compressor / valve fault, an air leak, or an inlet-filter blockage.
Compressor fault / will not build pressure
MediumSymptoms: Weak or no flow, compressor noisy or hot, thermal cut-out.
Root cause: Worn compressor / valve heads, or a cooling-fan fault.
Flow-control / flowmeter fault
MediumSymptoms: Flow will not adjust or does not match the setting.
Root cause: Worn flow-control valve or flowmeter.
Filter blockage
MediumSymptoms: Reduced performance, compressor working hard.
Root cause: Dirty gross-particle / cabinet / final bacteria filter.
Excessive noise / vibration
LowSymptoms: Loud operation, rattling.
Root cause: Worn compressor mounts or a loose panel.

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: Does not reach or hold the set pressure
- Run the device's pressure-verification against a calibrated manometer with a test lung / cap.
- Check for internal leaks and a blocked pressure-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: Blower noisy / failing / cannot meet flow
- Listen for bearing rumble or rattle from the blower.
- Check the inlet air filter is clean.
- Confirm no internal air leak.
- Replace the blower / motor assembly.
- Re-verify pressure and flow after replacement.
Symptom: Humidifier fault (no / excessive humidity, water in the tubing)
- Confirm the heater plate warms and the chamber seats fully.
- Inspect the chamber seal and the heated-tube connector.
- Check the humidity setting against ambient conditions.
- Replace the chamber seal or the heated tube.
- Replace the humidifier heater assembly if it will not heat.
Symptom: Therapy / compliance data will not download
- Try a known-good SD card in the correct slot.
- Check the card is not write-protected or corrupt.
- Confirm the wireless module / modem where fitted.
- Read the card on a PC to confirm data is being written.
- Replace the SD card / slot or the wireless module as isolated.
