WELL POINT INSTALLATION
1. Install the control valve and pressure gauge in the pump body.
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.
3. Drive the well, using "drive couplings" and a "drive cap". "Drive
fittings" are threaded all the way through and allow the pipe
ends to butt against each other so that the driving force of
the maul is carried by the pipe and not by the threads. The
ordinary fittings found in hardware stores are not threaded
all the way through the fitting and can collapse under impact.
"Drive fittings" are also smoother than standard plumbing
fittings, making ground penetration easier.
4. Mount the pump as close to the well as possible.
5. Use the fewest possible fittings (especially elbows) when
connecting the pipe from the well point to the pump suction
port. The suction 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 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 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, consider connecting two
or three well points to one suction pipe.
You have just completed the suction piping for your new shallow
well jet pump. Please go to Page 8 for discharge pipe and tank
connections.
CASED WELL INSTALLATION, 2" OR LARGER CASING
1. Install the control valve and pressure gauge in the pump body.
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.
3. Mount the pump as close to the well as possible.
4. Assemble the foot valve, strainer, and well pipe. Make sure
that the foot valve works freely.
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.
