WARNINGS

1. This pump and motor unit should be installed by a qualified electrician or serviceman in accordance with all applicable 
state and local codes and ordinances, and in accordance with the National Electrical Code. Improper installation may 
create a mechanical or electrical hazard which could cause damage to property and which could result in serious injury or 
death. Always follow the schematic on the motor for all electrical connections!

2. In order to avoid serious injury or death, always disconnect power to the motor before servicing the pump.

3. Never run the pump dry.

4. Never start the pump when the motor shaft is turning. To prevent unwanted reverse motor rotation, install a swing type check valve.

5. If you aren’t competent to install the pump, get help from a qualified source.

6. Maintain a minimum flow rate of at least two gallons per minute.

7. Visually inspect the pump and motor at least once a month. If there is any leakage from the shaft seal, replace it at once. The seal faces 

wear (just like car tires) and must be replaced periodically. For critical applications, replace the shaft seal yearly.

8. The motor leads must be energized in the correct order. If you are not sure of the sequence 

of your incoming supply line, remove the volute from the pump, connect the power and check 
rotation. When the rotation is correct, reinstall the volute. Do not test with volute in place! 
Never test rotation by bumping a switch!!! This will destroy the pump and void the warranty!!!! 
If it is incorrect, exchange any two of the connected leads and retest.
