Installation and Operation Precautions —

1.  The pump is equipped with a pressure sensing demand switch that 

     controls the maximum operating pressure.

2.  In addition, never subject the pump to pressures above 125 PSI 

     (8.5 bars).

3.  As long as there is inlet water pressure, the pump will not stop 

     forward flow of water even if the motor is turned off. Be sure the  

     system has positive means of shutting off water supply.

4.  Do not operate pump in an explosive environment. Arcing from the 

     motor brushes, switch or excessive heat from an improperly cycled 

     motor may cause an explosion.

5.  Do not locate the pump motor near low temperature plastics or 

     combustible material. The surface temperature of the motor may 

     exceed 250°F (120°C).

6.  Do not pump gasoline or other flammable liquids. Pump head 

     materials are designed for use with water only. Do not use with 

     petroleum products.

7.  Do not assume fluid compatibility. If the fluid is improperly 

     matched to the pumps’ elastomers, a leak may occur.

8.  To prevent electrical shock, disconnect power before initiating any 

     work. In the case of pump failure, the motor housing and/or pump 

     fluid may carry high voltage to components normally considered 

     safe. Therefore, always consider electrical shock hazard when 

     working with and handling electrical equipment. If uncertain, 

     consult an electrician. Electrical wiring should only be done by a 

     qualified electrician per local and state electrical codes.

Recommendations —

Electrical:

1.  

The PowerFlo™ series pumps are designed for intermittent duty.        

     Make sure that “OFF” periods are sufficient. Refer to Rapid 

     ON/OFF Operation. Consult the factory for particular data and 

     design criteria.

2.  

Be sure power supply used is adequate for the application.

3.  Pump and motor specifictions are based on an alternator

     charged battery (13.7 VDC)

4.  Use sufficient battery supply power. UTV and lawn tractor batteries 

     may affect pump performance due to low voltage and amp ratings.

Servicing —

Every Year: Check system against operating standards.

Every 2-3 Years: We recommend replacing the diaphragm and

checking against operating standards.

* Important return safety instructions:

When you return your pump for warranty or repair, you must always do the following:

1. Flush chemical residue from the pump (best done in the field).

2. Tag pump with type of chemicals having been sprayed.

3. Include complete description of operation problem, such as how pump was used, 

    symptoms of malfunction, etc. Since pumps can contain residues of toxic chemicals 

    these steps are necessary to protect all the people who handle return shipments, and 

    to help pinpoint the reason for the breakdown.
