1. Install the pressure regulator and pressure gauge in the pump body. See

Figure 1.

2. Assemble the ejector kit. See Figure 6. Follow the instructions

included with the kit in order to match the nozzle and venturi to your
well conditions.

3. Mount the pump as close to the well as possible.
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.

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.

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 suction pipe joints with PTFE pipe thread
sealant 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.

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.

Electrical for electrical connections.

2” Well

1. Install the pressure regulator and pressure gauge in the pump body. See

Figure 1.

2. Mount the pump as close to the well as possible.
3. Assemble ejector kit, well piping, and well head adapter according

to the instructions provided with the ejector package. See Figure 7.
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.

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 suction pipe joints with
PTFE pipe thread sealant 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.

5. Run piping from the discharge tee in the tank flange to the household

NOTICE The ejector kit supplied with your pump tank system will not work
with a 2” well. You must purchase kit part number FPAP2-P2 and well case
adapter J216-16A separately.
