Solar panel: 7V/1.4WPump parameters: DC 4.5-12VLarge flow: 200L/hLarge lift: 90cmProduct size: diameter 160*45mmInstructions1) Assemble the product according to the schematic diagram.2) Place the solar panel in a suitable place to ensure that the light is not blocked by other objects. When the solar panel receives sufficient sunlight, the water pump will work normally.3) When the water pump is just put into the water, there is air in it, which may affect the water spraying effect. It is recommended to wait for the water pump to spray water normally before connecting the nozzle.4) The water pump can be disassembled and cleaned regularly to prolong the service life of the product.Precautions1) This product uses a direct-drive water pump, which can spray water continuously only when the sun is full; when the sun is not enough, it may not spray water or spray water intermittently. In addition, since the efficiency of solar panels is affected by the intensity of light, the water spray effect of the fountain is also affected by factors such as weather conditions, seasonal changes, and geographic location.2) The water pump should not be dehydrated for a long time, otherwise the service life of the water pump will be shortened.3) Please keep the water clean and clean the water pump regularly. If there is debris in the pump, it will affect the normal operation of the pump.
