Step 1. Install the pressure regulator and pressure gauge in the pump body.
See Figure 4, Page 6.
Step 2. Assemble the ejector kit. See Figure 9. Follow the instructions
included with the kit in order to match the nozzle and venturi to
your well conditions.
Step 3. Mount the pump as close to the well as possible.
Step 4. 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 10 feet below the well’s water level while
the pump is running in order to prevent the pump from sucking air.
Step 5. 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.
Step 6. 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 pipe joints with Teflon™ tape or a
Teflon™-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.
Step 7. Run piping from the discharge tee in the tank flange to the household
piping. The discharge piping must be at least as large as the tank
tee. Install a relief valve in the discharge pipe capable of passing the
entire pump flow at 75 psi. Run a pipe from the relief valve to a floor
drain or some other convenient place to carry off the water.

Well (Figure 10)
Step 1. Install the pressure regulator and pressure gauge in the pump body.
See Figure 4, Page 6.
Step 2. Mount the pump as close to the well as possible.
Step 3. Assemble ejector kit, well piping, and well head adapter according
to the instructions provided with the ejector package. See Figure 10.
Use galvanized drop pipe with turned couplings to allow proper
flow. Follow the instructions included with the kit in order to match
the nozzle and venturi to your well conditions.
Step 4. Run two pipes (one smaller drive pipe, one larger suction pipe)
from the well to the pump. 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 pipe
joints with Teflon™ tape or a Teflon™-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.
Step 5. Run piping from the discharge tee in the tank flange to the household
piping. The discharge piping must be at least as large as the tank
tee. Install a relief valve in the discharge pipe capable of passing the
entire pump flow at 75 psi. Run a pipe from the relief valve to a floor
drain or some other convenient place to carry off the water.

NOTE:
The ejector kit supplied with your pump tank system will not work
with a 2” well. You must purchase kit part number FPAP2-P2 separately.
