install stabilizing post2

The stabilizing post prevents the pump from tipping over, especially during high winds.

Note: The top of the post can become deformed from pounding it into the ground. This can be avoided by placing a piece of wood between the hammer and the post.

To maximize pump performance, ensure the following criteria are considered in the following order.

1 identify pump installation location

install panel in full sunlight

install near water source

install near irrigated plot

3 attach pump to post

Lift the pump and align the stabilizing post with the square tube of the pump frame, and then lower the pump onto the post. Use the bolt located on the lower portion of the frame to hand tighten.

Measure the total lift required that the sunflower pump will need to lift the water at the installation location. Total lift includes both the depth the pump needs to lift and the the height the pump needs to push the water.

adjust piston stroke length

To maximize the efficiency of the pump, the piston stroke length needs to be set to match the estimated total lift. This is adjusted by changing the piston bearing position on the cam. Use the chart above to determine correct piston stroke length, depending on the intended total lift at the pump site.

5 adjust piston position

Loosen the bolt securing the piston rod until the rod moves independently of the yoke. Slowly rotate the flywheel until the yoke is at the lowest position. Once it’s at the lowest point, tighten the bolt to secure the piston rod to the yoke.

Warning: a spring is located in the yoke sleeve, if the piston rod is removed from the yoke sleeve the spring might fall out. Ensure the spring is replaced back into the sleeve before connecting the piston rod.

add elastic bands

Elastic bands are added to the pump to balance the load between the upstroke and the downstroke. The number of bands correlated to the total lift requirement of the pump, with 1 band for 1 meter of lift. Use the chart above to determine how many elastic bands you’ll need.

Slide the motor onto the motor support on the pump frame. Ensure the motor wheel aligns with the rubber on the flywheel.

9 ensure proper pump operation

Manually run the pump by slowly moving the flywheel clockwise. Observe operation of the pump to ensure proper alignment and function.

10 mount panel

Align the panel support with the holes located on the sides of the solar panel frame. Secure the solar panel to the panel support using the provided “L” bolt. Align the bottom of the panel support with the round hole on the solar pump frame and lower the panel support until the collar rests on the pump frame. Secure the support to frame by hand tightening the “L” bolt on the pump frame.

11 adjust panel angle

The angle of the panel can be adjusted by loosening the L bolts connecting the solar panel frame to the panel support. Adjust the panel to the desired angle and tighten L bolts to secure in place. The panel can also be rotated by loosening the L bolt securing the panel frame to the pump frame. To do this, Rotate and tilt the panel to the desired orientation and secure by tightening the L bolts.

12 prime pump

Using the outlet hose or a short hose, fill the pump chamber with water.

18 19

13 connect hoses

Connect the inlet and outlet hoses to the pump union, ensure a secure fit by using the provided hose clamps. Tighten the union by hand to ensure an air tight fit. The inlet and outlet hoses should be removed from the pump using the unions, this will ensure an airtight seal.
