Connection Procedure:

1. Connect the ground wire first as shown in Figure 4.
The ground wire must be a solid copper wire at least
as large as the power supply wires.
2. There must be a solid metal connection between the
pressure switch and the motor for motor grounding
protection. If the pressure switch is not connected to
the motor, connect the green ground screw in the
switch to the green ground screw under the motor
end cover. Use a solid copper wire at least as large as
the power supply wires.
3. Connect the ground wire to a grounded lead in a
service panel, to a metal underground water pipe, to
a metal well casing at least ten feet (3M) long, or to a
ground electrode provided by the power company or
the hydro authority.
4. Connect the power supply wires to the pressure
switch as shown in Figure 6.
Operation

Priming the Pump

NOTICE: To properly prime the pump, install a pipe tee in
the discharge piping (see Figure 1, Page 3).
To prevent damage to internal parts, do not start motor
until pump has been filled with water.
To prime pump:
1. Remove priming plug (Purchase separately; Figure 1,
Page 3).
2. Fill pump with water.
3. Replace priming plug, using PTFE pipe thread sealant
tape or a PTFE-based pipe joint compound on plug
threads; tighten plug.
4. Start the pump. Water should be pumped in 1-2
minutes. If not, repeat steps 1, 2 and 3.
On shallow depths to water (10 feet or less), the
pump will probably prime the first time after the
following steps 1 through 4 above.
From 10 to 20 foot depths, you might have to shut off
the pump and repeat steps 1, 2 and 3 several times.
