Specification:<br />Monocrystalline silicon solar panels: 7 v / 1.4 W<br />Solar panel size: 160 mm in diameter.<br />Lotus leaf size (material: EVA) : 280 mm in diameter<br />Water pump parameters: DC 3-12 v<br />Maximum flow: 180 l/h<br />Maximum head: 80 cm                         <br /><br />The pump will start automatically in 3 seconds when bright sunlight shines on the solar panel directly without any shadow.<br />Method of Operation<br />1. Assemble the product according to the sketch map. <br />2. Put it on the water and make sure that the solar panel is not sheltered from the sun. Then it will work normally as soon as the sunshine is enough.<br />3. There's some air in the pump at the moment that it's put in the water. You'd better not connect the spray head to the pump until it sprays normally.<br />Notes<br />1. The pump will work continuously only when the sunlight is enough since it's directly driven by the sunlight. Due to the efficiency of solar panel is influenced by sunlight intensity， the water spray is also affected by weather， season， place， etc. <br />2. Don't make the pump work without water for a long time， otherwise its lifespan will be shortened.<br />3. Clean the pump regularly. If it's dirty， it will stop working.<br />4. Be careful when using it. And don't let children play with it.<br /><img src="http://img6.eachbuyer.com/x9/p100/eb02555_1.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb02555_2.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb02555_3.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb02555_4.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb02555_5.jpg" />
