Cautions for use:
The spray head should be flat (upright), the water surface should keep more 5-10MM higher than the prominent water level probe, which can not be too high. Otherwise it can not have fog or less fog than what is should have. When the water level is below the probe, the atomizer will automatically go into protection mode and stop to spray.
The atomizing film should be often washed and and kept clean, otherwise it will not spray or the fog will be small. If the fog is still limited / small after you cleaned the atomizer film, it should be replaced.
Do not put the spray in the water with high concentration acid and high alkali to avoid the spray head being corroded.
