ELECTRICAL INFORMATION
7. Strainer should be attached to the inlet side.
4. Plumb the system using high pressure (2x pump rating), braided, flexible tubing to minimize vibration/noise.
12. This pump should be wired on its own dedicated circuit. Connect the positive lead (red) to the positive
terminal of your battery and the negative wire (black) to the negative terminal of your battery.
14. The electrical circuit should be protected with an over-current protection device (fuse) in the positive lead.
This pump requires a 15 amp fuse.
13. In an easily accessible location, install a switch to control electricity to the pump. Turn the pump off when
not used for extended periods or when the tank is empty.
5. Do not apply inlet pressure in excess of 30 psi. In general, try to avoid any inlet pressure completely.
6. Avoid any kinks or fittings which could cause excessive restrictions.
8. The fittings must be secured to avoid leakage.
10. If a check valve is installed in the plumbing, it must have a cracking pressure of no more than 2 psi.
9. Use clamps at both ends of hose to prevent air leaks into the water line.
11. If applying a sealer or plumbing tape, be careful to not overtighten, as they may be sucked into pump.
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
2. We do not recommend the use of metal fittings. When possible, use the provided plastic fittings.
3. Do not adjust the bypass personally without the help of technician.
4. Lack of sanitizing and maintenance is one of the main reasons of under performance of the pump. Please do
maintenance and winterize the pump at appropriate times, especially before and after a period of storage.
1. Flexible potable water hose or PEX tubing is recommended instead of rigid piping at pump. If you choose to
use rigid piping, provide a short length of hose between pipe and the pump to avoid noise and vibration.
