1.2. The product surface features zinc alloy electroplating, and the spray head is made of plastic. Rinse sealants when cleaning to avoid surface scratches, though this will not affect functionality. Thank you for your understanding. 2. Lantern: No light water level sensor switch. Suitable for: family rooms, airconditioned spaces, beauty salons, hotels, hospitals, offices, nurseries, OK rooms, and other living areas. Usage: 1. Find a container and fill it with clean water (pure water). Place the atomizer head flat on the container filled with water. 2. Ensure the water depth covers the atomizer head's side door (marked with black font) by 12 cm, corresponding to the water level sensor. If the water is too , it will not produce mist. 3. Turn on the power to start spraying. Note: Avoid splashing water near electrical components. Note: A single spray head cannot be used alone; it must be paired with a 24V 800mA power supply. 3. The atomizer head's performance is closely related to water temperature. Initially, the results may not be ideal, but after a few minutes or by adding slightly hot water, the effect will improve significantly. 4. Avoid using containers with too much water, as it may render the device ineffective. The water depth is 27 cm; exceeding this range will reduce mist output.
