PRECAUTIONS: 1) This product is a direct drive solar powered water pump. There is no external battery. The height of the water jet depends solely on the strength of the sun. When the sun is weak, the pump will not work continuously but will repeat automatically until the sunlight reaches a certain intensity. The pump resumes continuous operation. When using the product, expose it to unobstructed sunlight. Blocking shadows affects the normal operation of the pump. 2) The pump should be completely submerged in water and should not leave the water for a long time. When the pump is just immersed in water, there is air in the pump. It is recommended to place the pump in the nozzle after normal spraying. 3) Please keep the water clean and clean the pump regularly. This will prevent the pump from getting into dirt and not working properly.
