Safety Information
Please read and adhere to the following safety guidelines to ensure proper operation and prevent injury or damage:
- Avoid direct skin contact with undiluted essential oils.
- Keep the device and essential oils out of reach of children and pets.
- Ensure proper ventilation in the area where the diffuser is used.
- Use only 100% pure essential oils.
- Dilute oils with carrier oils if necessary, especially for thicker oils.
- Do not use camphor tree or agarwood oils.
- Do not use resin or thick oils, as they may cause clogging.

Maintenance
Regular maintenance ensures optimal performance and longevity of your diffuser:
- Monthly Cleaning: Clean the diffuser monthly using 90% or greater ethanol, ethyl, or isopropyl alcohol. This helps prevent oil buildup and maintains mist output.
- Oil Selection: Always use 100% pure essential oils. While the diffuser is designed for undiluted oils, if an oil is particularly thick, it may be diluted with a carrier oil. Avoid camphor tree, agarwood, resin, or excessively thick oils as they can clog the nozzle. Do not dilute with water.
- Oil Storage: Essential oils can thicken when exposed to sunlight or cold temperatures, which may affect diffusion. Store oils properly.

Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Mist output decreases significantly after 1-2 months of use. | Oil residue buildup or clogging. | Clean the diffuser thoroughly according to the maintenance instructions. |
| No mist is coming out, but the mist indicator light is blinking green. | The diffuser is currently in a pause cycle according to its set mist intensity level. | This is normal operation. The diffuser will resume misting after the set pause time. |
| Diffuser powers off unexpectedly. | Device was inverted or tilted (Auto Spill-Protection activated) or battery is low. | Return the device to an upright position. If the issue persists, recharge the battery. |
