General Safety Information

1.    Know the pump application, limitations and potential hazards.

  -  Always install a pressure relief valve to match the system pressure rating and the maximum flow rate.

  -  Disconnect power and relieve all pressure from the system before attempting to install, service, relocate or perform 

any maintenance. Lock the power disconnect in the open position. Tag the power disconnect to prevent unexpected 

application of power. Install a screen around the inlet pipe to prevent entrapment of swimmers (if applicable).

2.  Drain all liquids from the system before servicing.

3.   Secure the discharge line before starting the pump. An unsecured discharge line will whip and possibly cause personal 

injury and/or property damage.

4.  Check hoses for weak or worn conditions before each use. Make certain all connections are secure.

5.  Periodically inspect pump and system components. Perform maintenance as required.

6.  Personal Safety:

   

a. Wear safety glasses at all times when working with pumps.

   

b. Keep work area clean, uncluttered and properly lighted – replace all unused tools and equipment.

   

c. Keep visitors at a safe distance from work area.

7.   When installing pump, cover the well to prevent foreign matter from falling into well and contaminating the water and 

damaging internal mechanical pumping components.

8.  Always test the water from the well for purity before use. Check with local health department for test procedure.

9.   Complete pump and piping system MUST be protected against freezing temperatures. Freezing temperatures could 

cause severe damage and void the warranty.

10. Do not run the pump dry or damage will occur.

11. The unit should be connected to a grounded circuit equipped with a ground fault interrupter device.

12.  Before installing the pump, have the electrical outlet checked by a licensed or certified electrician to make sure the outlet 

is properly grounded.

13. Make sure the line voltage and frequency of electrical current supply agrees with the motor wiring.

14.  Do not attempt repairs to the electric motor. All repairs to the motor must be completed at a licensed or certified electrical 

motor repair shop.

   

Do not touch an operating motor. Modern motors are designed to operate at high temperatures.

15.  Avoid kinking the electrical cord and protect from sharp objects, hot surfaces, oil and chemicals. Replace or repair 

damaged or worn cords immediately.

16. Keep fingers and foreign objects away from ventilation and other openings. Do not insert any objects into the motor.

   

Risk of electrical shock! Never connect the green (or green and yellow) wire to a line terminal!

17. Use wire of adequate size to minimize voltage drop at the motor.

   

-  Do not handle a pump or pump motor with wet hands, when standing on a wet or damp surface or when 

standing in water. Fatal electrical shock could occur.

   

-  Pump motor is equipped with an automatic resetting thermal overload protector and may restart 

unexpectedly. The overload protector tripping is an indication of motor overloading because of operating 

pump at low heads (low discharge restriction), excessively high or low voltage, inadequate wiring, 

incorrect motor connections.

18. This pump has been evaluated for use with water only. 

   

 Do not use to pump flammable or explosive fluids such as gasoline, fuel, oil, kerosene, etc. Do not use in 

explosive atmosphere.
