Instructions: 1) Install the product according to the diagram. 2) Place the solar panel in a suitable place to ensure that it is not blocked by other objects. When the solar panel receives enough sunlight, the water pump will work normally. Precautions: 1. This product is a solar-powered water pump without an external battery. The height of the water spray depends entirely on the strength of the sun. When the sun is weak, the water pump will not work continuously, but will automatically start repeatedly until the sun reaches a certain intensity. After that, the water pump will return to continuous working mode. Place the product under free sunlight when using, because shadows will affect the normal operation of the pump. 2. The water pump must be fully immersed in water and cannot be dried for a long time. When the water pump is just immersed in water, because there is air in the water pump, it is recommended to wait until the water pump sprays water normally before inserting the nozzle. 3. Keep the water source clean and clean the water pump regularly to prevent foreign objects from being sucked into the water pump and causing the water pump to malfunction.
