Product Performance:
1. The pump is driven directly by the sunlight. So it will work continuously only when the sunlight is enough. As the power of the solar panel is depended on the sunlight, the pump is also affected by weather, seasons, places, etc.
2. Don’t make the pump work without water for a long time, or its lifespan will be shortened.
3. Don’t put the solar panel and the control box in water, or it will be damaged.
4. Clean the pump regularly.
5. The solar panel is made up of glass and metal. You must be careful when using it. And don’t let children play with it.
6. The moment that the pump starts to work, its spray height will be higher than the normal range and it will return to normal after 3-5 seconds.

Method of Operation:
1. Assemble the product according to the sketch map of the instruction. Then set it on the places where the solar panel is not sheltered from the sun.
2. The pump will work normally as soon as the sunshine is enough.
3. There is some air in the pump at the moment when it is put in the water. You'd better not concentrate the spray head to the pump until it sprays normally.

Dynamic Head

The effect of the Earths gravity on the "lift" or head pressure is fairly simple; for every vertical foot of distance the pump moves the water you are adding one foot of head pressure so the ratio is a 1:1 ratio. The effects of the friction, caused by water as it travels through your hose or pipes, on the total head pressure is a little more difficult to calculate especially as there are slight variations in pipe friction in different hose materials and the smoothness of the inner bore. Basically. for every ten feet of pipe through which the water has to travel travel horizontally will contribute 1 foot of head height; the ratio of the pipe friction loss is a 10:1 ratio.

Plumbing fixtures and bends and corners in your hose also increase the total head you must calculate to ensure the proper final volume from your pump. Every corner with a 90 degree elbow in your plumbing will add 1 foot of head pressure  with a 1:1 ratio. 45 degree elbows, tees and even insert couplers can all have an impact on the final flow.

If you install a pump 40 feet away from the top of your waterfall which is 6 feet above the pump and the tubing is a single run of 40 feet horizontally then you add 4 feet of head for the tubing length (the 10:1 ratio) to the 6 foot differnetial between the pump location and the final height of the waterfall so your final total dynamic head calculation would be 10 feet. This means your final volume of water flow in this water feature or application would be the volume of flow on the performance curve that equaled the gallons per hour at 16 feet. This volume will certainly be much less than the initial volume the pump can move at an open flow or a zero head.

If in the above example your 40 feet of horizontal tubing run also required 3 elbows of 90 degrees then an additional 3 feet of theoretical head would be added and your final flow result would be at 19 feet on the performance curve of the pump. In this example you would want to choose a pump that has the desired GPH rating at 9 feet of head pressure.  Tubing size is also an important factor in accounting for head pressure loss, in general you should never reduce the diameter of the tubing below what the output size of the pump is, this will drastically increase head pressure, and reduce pump performance.  For maximum pump performance, using the largest tubing that is practical is the best choice. A best practice is to use a hose with an inner diameter that is the same as your pumps outlet fitting.
