WELL POINT INSTALLATION (Figure 5)
Step 1. Install the control valve and pressure gauge in the pump body (see
Figure 1).
Step 2. Install ejector kit FP4855 with a Series 4200 pump, or kit FP4875
with a Series 4300 pump (kits are sold separately). Follow the
Suction Pipe
From Well instructions provided with the kit. Align the venturi with the top
hole on the front of the pump (see Figure 4).
Step 3. Drive the well, using "drive couplings" and a "drive cap". "Drive
fittings" are threaded all the way through and allow the pipe ends
Priming to butt against each other so that the driving force of the maul is

tion easier.
Step 4. Mount the pump as close to the well as possible.

Step 5. Use the fewest possible fittings (especially elbows) when connect-
ing the pipe from the well point to the pump suction port. The suc-
tion pipe should be at least as large as the suction port on the pump
(include a check valve – see Figure 5). Support the pipe so that

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 teflon tape or pipe joint
compound approved for use on PVC. Joints must be air- and water-
tight. If the suction pipe can suck air, the pump cannot pull water
from the well. If one well point does not supply enough water, con-
sider connecting two or three well points to one suction pipe.

CASING (Figure 6)
Step 1. Install the control valve and pressure gauge in the pump body (see
Figure 1).
Step 2. Install ejector kit FP4855 with a Series 4200 pump, or kit FP4875
with a Series 4300 pump (kits are sold separately). Follow the
instructions provided with the kit. Align the venturi with the top
hole on the front of the pump (see Figure 4).
Step 3. Mount the pump as close to the well as possible.
Step 4. Assemble the foot valve, strainer, and well pipe (see Figure 6).
Make sure that the foot valve works freely.
Step 5. Lower the pipe into the well until the strainer is five feet above the
bottom of the well. 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. Install a sanitary well seal.

Valve Step 6. Install a priming tee, priming plug, and suction pipe to the pump
(see Figure 6). Connect the pipe from the well to the pump suction
port, using the fewest possible fittings – especially elbows – as fit-
tings increase friction in the pipe. The suction pipe should be at
least as large as the suction port on the pump. Use teflon tape or a
