6. Using tire pressure gauge, check air pressure in tank at valve stem located on the back of the tank (B).
Air pressure in the tank (B) must be 2 psi lower than the "cut-in" of the pressure switch.
NOTE: The pump (A) has a 30/50 psi pressure switch, which means the "cut-in" is 30 psi; therefore, the tank (B) needs to be
set to 28 psi. To check the pressure in the tank (B), use a tire pressure gauge (not included). If more air is needed, add air to
the tank with a tire pump or air compressor. If less is needed, bleed out some air.
7. Mount the pump as close to the well as possible.
8. Connect two pipes (1" drive, 1-1/4" suction) to the ejector and lower the ejector into the well until it is five feet from the
bottom. It should also be at least 9 feet below the well's water level while the pump is running in order to prevent the pump
from sucking air.
10. Install a sanitary well seal and connect the ejector piping to the pump. Use steel nipples through the well seal with flexible
poly pipe to avoid crushing the plastic pipe when tightening the seal.
11. Support the pipe so that there are no dips or sags in the pipe, so it doesn't strain the pump body, and so that it slopes
slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction
pipe joints with PTFE pipe thread seal ant tape or a PTFE-based pipe joint compound. Joints must be air and water-tight. If
the suction pipe can suck air, the pump cannot pull water from the well.
You have just completed the plumbing for your new double pipe deep well jet pump. Please go to priming.
