4. Setup and Installation
Follow these steps for proper installation:
- Placement: Position the pump on a stable, level surface in a well-ventilated area, protected from direct sunlight and freezing temperatures.
- Inlet Connection: Install the provided check valve at the inlet. Ensure at least two interface gaskets are placed. It is recommended to wrap adapters with raw tape (Teflon tape) before installation to prevent water leakage. The pump has a 1-inch inlet.
- Outlet Connection: The pump comes with a pre-installed adapter at the outlet. Connect your water system or garden hose to the 1-inch outlet.
- Electrical Connection: Plug the pump into a standard 110V AC outlet. The 20 ft power cord provides ample reach.
- Priming (if necessary): For initial use or after extended periods of non-use, ensure the pump is properly primed by filling the pump casing with water before starting.

5. Operating Instructions
The pump is designed for automatic operation based on water demand.
- Automatic ON/OFF: The intelligent pressure switch automatically turns the pump on when water is drawn (e.g., opening a faucet) and turns it off when water flow stops.
- Pressure Adjustment: The cut-in pressure can be adjusted using the pressure screw behind the pressure tank. This allows you to set the desired starting pressure for the pump.
- Pressure Monitoring: The built-in pressure gauge provides a visual indication of the current water pressure in the system.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your pump:
- Regular Inspection: Periodically check for any leaks, loose connections, or unusual noises.
- Cleanliness: Keep the pump exterior clean and free from debris. Ensure the cooling fan is not obstructed.
- Winterization: In cold climates, drain the pump completely and store it in a frost-free environment to prevent damage from freezing water.
- Check Valve: Periodically inspect the check valve for proper function and clear any blockages.
7. Troubleshooting
If you encounter issues with your pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; Clogged inlet/outlet; Motor overload. | Check power connection; Clear obstructions; Allow motor to cool and reset. |
| Low water pressure | Insufficient water supply; Air in the system; Clogged filter/pipes. | Ensure adequate water source; Re-prime the pump; Check and clear any blockages. |
| Pump runs continuously / Does not shut off | Leak in the system; Pressure switch malfunction; Incorrect pressure setting. | Check for leaks in plumbing; Inspect pressure switch; Adjust cut-in pressure setting. |
| Pump stops unexpectedly | Water shortage; Overheating. | Check water supply; Allow pump to cool down. The pump has automatic protection features. |
