Note: If the control console becomes unresponsive after initial operation, unplug the unit and plug it back in to reset. This is a design characteristic for certain models.
Maintenance
Cleaning the Diffuser
Regular cleaning ensures optimal performance and longevity of your AromaPro diffuser:
- Disconnect the power adaptor from the electrical outlet.
- Remove the oil bottle from the compartment.
- Wipe the exterior of the diffuser with a soft, dry cloth. Do not use abrasive cleaners or allow liquids to enter the internal components.
- If changing oil types, it is recommended to clean the nebulizer nozzle. Fill a small amount of rubbing alcohol into an empty oil bottle and run the diffuser for 15-30 minutes in a well-ventilated area. This helps clear any residue from the previous oil.
- Ensure all parts are dry before reassembling and reconnecting power.
Replacing Oil Bottles
When the oil bottle is empty, follow the steps for "Filling the Oil Bottle" in the Setup section to replace it with a new or refilled bottle.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No fragrance detected | Oil bottle empty or improperly installed; Nebulizer nozzle clogged; Intensity setting too low. | Check oil level and ensure bottle is correctly seated. Clean the nebulizer nozzle as per maintenance instructions. Increase fragrance intensity setting. |
| Unit not powering on | Power adaptor not connected; Power outlet not functional. | Ensure power adaptor is securely connected to both the unit and a working electrical outlet. Test the outlet with another device. |
| Control panel unresponsive after initial setup | Normal operational characteristic for certain models. | Unplug the unit from the power source, wait 10 seconds, then plug it back in. This will reset the control panel for further adjustments. |
