How to use
- Remove the atomizer head and take out the included 60 ml oil reservoir.
- Fill with compatible waterless fragrance oil only. Do not add water.
- Secure the oil reservoir and atomizer, then plug the diffuser upright into a dry wall outlet.
- Use the top buttons for G1-G3 or the repeating 3H/6H routine, or connect through Bluetooth for a custom schedule.
Care and placement
Keep the diffuser upright and away from sinks, showers, steam and splash zones. Clean at scent changes or every 1-2 months. Remove the oil reservoir and atomizer head, soak them in alcohol for 5-10 minutes, then allow all parts to dry before refilling. The box includes the diffuser, empty 60 ml oil reservoir, cap and user manual. Waterless fragrance oil is sold separately.
