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: Mask-leak reported but mask fits
- Slide the humidifier chamber fully into the cradle until the unlocking handle clicks into place.
- Make sure the silicone air-outlet cover on the back of the device is fully inserted.
- Insert the gasket seal into the water chamber if missing.
- Re-check the therapy device's leak indication.
- If the enclosure is cracked or the device sounds harsh, stop use and contact the provider.
Symptom: Water in the tubing
- Lower the humidity / heat setting.
- Use a heated or insulated tube and keep the hose below the mask.
- Route the hose to drain back toward the chamber.
- Confirm the room is not unusually cold.
- Re-check after a night of therapy.
