Lantern: Water Level Sensor Switch Suitable For: Homes, air-conditioned rooms, beauty salons, hotels, hospitals, offices, kindergartens, and karaoke rooms. How to Use: 1. Place the unit on a clean water container. Do not use purified or distilled water. Ensure the atomizing head is fully submerged and lying flat on the water surface. 2. The water depth should cover the atomizing head’s side sensor (marked with black text) by 1–2 cm. Excessive water depth will prevent mist generation. 3. Turn on the power to begin misting. Avoid exposing the power adapter to water. Notes: 1. The spray head requires a 24V 800mA power supply to operate. It cannot function without this power source. 2. The product housing is zinc alloy electroplated. The atomizing head is made of plastic. Avoid using abrasive cleaners or scrubbing the surface, as this may cause minor scratches—though functionality remains unaffected. 3. Atomization performance is affected by water temperature. Initial mist output may be low; after a few minutes of operation—or when using slightly warm water—performance improves significantly. 4. Fill the water container to a level between 2–7 cm. Overfilling reduces efficiency; levels below 2 cm result in weak or no mist output.
