Introduction
Thank you for choosing the URPOWER 500ml Aromatherapy Essential Oil Diffuser Humidifier. This versatile device combines three functions in one: an aromatherapy diffuser, a humidifier, and a night light. Utilizing advanced ultrasonic diffusing technology, it breaks down water and essential oils into fine micro-particles without heat, preserving the beneficial properties of essential oils. With a large 500ml water capacity, it can operate for up to 10 hours and features an automatic shut-off when water levels are low. This manual provides detailed instructions for safe and effective use of your new diffuser.
Safety Instructions
- Always ensure the water tank is filled below the Max line before operating the diffuser.
- Do not use undiluted essential oils.
- Keep the diffuser and essential oils out of reach of children and pets.
- Avoid direct skin contact with essential oils.
- Use the diffuser in a well-ventilated area.
- Do not place the diffuser on carpet or a towel, as this can block air intake and cause overheating. Place on a smooth, flat surface.
- Ensure the power plug is fully inserted into the device and the outlet.
- Clean the diffuser regularly, at least once a week, to prevent mineral buildup.

Maintenance
Regular cleaning is essential for optimal performance and longevity of your diffuser.

- Clean the ultrasonic disc (the small metal disc at the bottom of the tank) with a cotton swab dipped in white vinegar. Do not use harsh chemicals or abrasive materials.
- Wipe the exterior of the diffuser with a soft, dry cloth.
- Ensure all parts are completely dry before reassembling and storing or reusing the diffuser.
