SINGLE PIPE SYSTEM
1. Check the foot valve to see that it seats properly. Be sure
Venturi is wrench tight in the ejector body.
2. After the foot valve has been attached to the ejector assembly
and is being lowered into the well on the first section of the
suction pipe, it may be necessary to turn it. It should only be
turned clockwise to avoid loosening the packer leathers and foot
valves.
3. Fill the pipe and well casing with water. If water recedes,
there might be a leak. If no leak occurs, continue the procedure
with each length of the pipe until the ejector-packer assembly is
lowered to its final position, 10 feet below the drawdown level
of the well. If the pump is being installed in a 2" well, use only
special turned couplings on the suction pipe (steel pipe only) to
provide for better flow.
4. Connect the suction pipe to the well seal and the well seal to
the well casing and adjust the bolts tightly.

5. Connect the drive pipe to the lower opening of the pump.
Connect the suction pipe to the upper opening of the pump.
6. After the piping is completed, and the motor is properly wired
to electric service, it is now ready to operate. Remove the priming
plug on top of the pump and fill it with clean water. Allow time
for the air to escape and refill, if necessary, before replacing the
priming plug.
7. An external regulating valve is recommended with deep well
installations. Follow the instructions included with the regulating
valve in order to correctly set the regulating valve for your
installation.
8. When the unit has built up to maximum pressure and has
automatically stopped, check all piping for leaks, as they will be
under pressure.
