Electrical Connections
Employ a licensed electrician or water systems contractor to ensure installation is done properly. All
wiring must be done in accordance with national and local electrical codes. Follow the cable splicing kit
instructions.
1. Make sure the power supply corresponds with the electrical rating of the motor.
• For 3-wire, single phase pumps, check electrical rating of the control box.
2. Install a fused disconnect switch or circuit breaker.
3. Ground the pump and the distribution panel with the motor’s green conductor.
4. For two-wire pumps, make wiring con
-
nections.
5. For three-wire, single-phase pumps,
make wiring connections and install the
control box.
• Mount in an area protected from
rain, snow, high temperatures, and
temperatures below 14 °F (-10 °C).
• Refer to the control box’s wiring dia -
gram.
• Install a magnetic contac -
tor if the pressure switch is
not sufficient to handle the
motor’s electrical rating.
The pressure switch is then
used as a pilot circuit to
control the contactor.
6. Install a separate lightning
arrestor close to the wellhead.
7. Test the unit. Brace pump shell
and apply power momentarily.
8. Ensure pump rotation is clock -
wise when viewed from pump
discharge.
9. Place the motor and pump
labels in the circuit breaker
box for future reference.
Physical Installation
Refer to “Typical Installation” on page 2 .
1. Confirm that the motor’s lead wires are secure under the pump’s lead guard.
2. Install a pressure tank per manufacturer’s recommendations.
3. Attach a 3/16” diameter to 1/4” diameter steel safety cable to pump.
IMPORTANT: If using a different type of cable, confirm the system weight does not exceed the
limit.
4. Attach schedule 40 galvanized pipes to pump for installations up to 600 ft (180m).
• For deeper settings, use schedule 40 pipe for the bottom 600 feet (180m) and schedule 80 for
the remainder.
