Connect the Hoses
Inlet Hose – Keep the inlet hose lengths as short as possible. Do no use thin-wall hose or soft tubing on the pump's
intake, as it may collapse under suction and restrict the flow. Hose reinforced with steel braid is recommended. If
you elect to use polyethylene pipe (black flexible polypipe) be aware that it can be prone to slight leakage at the
fittings so ensure all connections are watertight.
The inlet must not be obstructed or restricted by undersized pipe, excessive suction lift, or a clogged filter.
Excessive suction at the pump inlet causes cavitation (formation of vapor bubbles). A cavitating SunCentric will not
pump any fluid.
Avoid humps in the intake line that can trap air pockets and block the flow. Ensure the inlet hose is free of leaks.
The supplied foot valve should be installed at the end of the inlet hose at the water intake source. This valve is
important to install because it allows water to flow in one direction only, helping to keep the pump primed when not
running. It is required in any case where the pump is located higher than the low-water level in the source.
Outlet Hose – The length of the outlet hose is not as critical as the inlet hose length, though the SunCentric pump is
not intended to pressurize the outlet side. Maximum performance is achieved when the SunCentric can open flow
to flood the intended irrigation area.
Mount the PV's to the Rack
Dankoff Solar recommends that you attached the PV's to the rack hardware first, then lift the entire unit onto the
Rack Mounting Pole.
To do so, lay each PV face down on a soft surface (cardboard works well), and align them together along their long
edge, with cables at the same end. This will be the 'bottom' of the solar array. The photo below is an illustration but
may not be the same PV's in your kit. The installation principle is the same, however.
