tion device (fuse) in the positive lead. This pump requires a 10 amp 

fuse (12V) or a 5 amp fuse (24V).

15.  The pump circuit should not include any other electrical loads.
16.  As the water supply pump is non-essential, reference the wire chart 

under the electrical information. Be sure to have the correct wire 
sizing for the length of wire you are using.

17.  After installation, check the voltage at the pump motor. Voltage 

should be checked when pump is operating. Full voltage must be 
available at the pump motor at all times. 

Notes

:

1.  Flexible potable water hose or PEX tubing is recommended instead 

of rigid piping at pump. If using rigid piping, provide a short length of 
hose between pipe and the pump to avoid noise and vibration.

2. 

Metal fittings are not recommended. When possible, use the provid

-

ed plastic fittings. 

3.  Do not adjust the bypass without the help of a technician.
4.  Lack of sanitizing and maintenance is one of the main reasons of 

under performance of the pump. Please perform maintenance and 
winterize the pump at appropriate times, especially before and after 
a period of storage.

About the Bypass

Please consult a professional technician in the case that the bypass 
needs adjustment. Improper adjustment of the bypass may damage the 
pump.
The bypass comes preset for optimal operation of the pump. If your 

application calls for a different setting for the bypass, you may change it 

yourself. Carefully tighten the screw to increase or loosen the screw to 
decrease the minimum operational pressure of the bypass.

 

CAUTION

Please follow the instruction manual to install the product. Any action 
outside what is recommended in this manual may bring damage to the 
pump. Any inappropriate installation or operation that causes the pump 
damage is not covered by warranty.
