1. Inspect the motors internal wiring to ensure voltage supply is matched between the motor and the
power source. If voltage does not match, it will damage the motor and void the warranty.
Example: If connecting your pump to a 115V circuit, make sure the motor connections match
the 115V wiring diagram listed on your particular motor.
2. Supply voltage must be /- 10% of nameplate voltage indicated on the motor. Incorrect
voltage supply may result in fire or damaged motor and voids the warranty. If you are not certain,
please consult with a licensed electrician.
3. Use designated supply wire size specified in the chart below. Correct wire size is necessary to
avoid electrical insufficiencies, allowing the motor to run cooler, more efficiently and eliminating line
voltage loss. It is important to connect your pump to a ground fault circuit interrupter (GFCI) for safety.
4. Wire motor following the connection diagram located on the motor. Note differences in high and low
voltage arrangements. If a cord has been preinstalled the connection was completed at the factory.
5. Be sure all connections are clean and tight. Ensure the motor is properly grounded. Typically a green
ground terminal is located inside the motor connection box. The ground wire must be properly
connected to an electrical service ground to safely operate.
6. The pump must be connected to an adequately sized circuit. It is recommended to have a dedicated
circuit that will prevent voltage drop from other loads as occurs on shared circuits.
7. When using 3 phase power the motor leads must be energized in the correct sequence to provide
the correct motor rotation. When viewed from the back end (opposite drive end), the motor must
rotate clockwise. Incorrect rotation could destroy the pump and void the warranty.
If sequence of the incoming electrical supply lines is not known, briefly connect the power for a
second or two to determine the rotation while looking at the fan through the motor end plate on
the back end (opposite drive end) of the motor. If you are unable to see the fan you will need to
remove the drip cover (solid plate) on the back end of the motor (opposite drive end) in order to see
the motor shaft as this unit type will not have a visable fan. If the rotation is incorrect, exchange any
two of the connected leads and retest.
* Risk of shock! Connect only to a ground fault circuit interrupter (GFCI). Contact an electrician if uncertain.
* Do not bury electrical cord unless installed in certified conduit. Locate the cord safely to minimize accidental damage.
* Replace damaged cords immediately to minimize risk of electric shock.
* Do not use extension cords to supply electricity to the pump.
WARNING
Before wiring any part of the motor be sure the power is disconnected.
It is recommended that wiring be performed be a licensed electrician or professional service person.
If pump has a factory preinstalled cord, wiring has already been set and this step is not needed; unless
voltage change is required in which case the cord will need to be removed and steps followed below.
