General Safety Information

® Power-Flo  is a registered trademark of Power-Flo 

Technologies Inc. Alteration Rights Reserved. 1/16, 10/2020, 1/2021

Before installation, read the following 

instructions carefully. Failure to follow 

instruction and Safety information could cause 

serious bodily injury, death and/or property 

damage. Each Power-Flo pump is individually 

factory tested to insure proper performance. 

Closely following these instructions will 

eliminate potential operating problems, 

assuring years of trouble-free service.

 

 

 Installation, wiring,

 

 

 and junction 

connections must be in accordance with 

the National Electric Code and all applicable 

state and local codes. Requirements may vary 

depending on usage and location.

 

 

  Installation and

 

 

   servicing is to be 

conducted by qualified personnel only.

 

 

  This pump is 

not

 

 

   intended for use in 

 swimming pools, spa areas or water 

 installations where human contact 

 with pumped fluid. 

 

 

 Risk of electric shock. 

 

 

  To reduce risk of 

  electric shock, always disconnect 

  pump from power source before 

  handling. 

Lock out power & tag.

  In the event the 

  retaining screws have

  been pulled out of the

 housing, 

DO NOT

 replace them. Use

 of any other screw may short out 

 the stator windings, creating a risk of 

electrical shock.

  The addition of 

  petroleum based fluids 

or certain chemical additives to the system 

voids the warranty.

 Pumps build up heat 

 and pressure during

 operation. Allow time

 for pumps to cool 

 before handling or

 servicing.
