6. Setup and Installation
Proper installation is crucial for the pump's performance and longevity. Follow these steps:
- Mounting: Secure the pump in a dry, well-ventilated area, protected from direct sunlight and freezing temperatures. Ensure the mounting surface is stable.
- Inlet Connection: Connect the water source to the pump's inlet port. Use the provided 1/2" MNPS inlet fittings and barbed adapters as needed. Install the 50 mesh inlet strainer on the suction side to prevent debris from entering the pump.
- Outlet Connection: Connect the pump's outlet port to your water distribution system. The pump is equipped with 1/2" MNPS outlet fittings.
- Electrical Connection: Connect the pump to a 12V DC power source. Ensure correct polarity (red wire to positive, black wire to negative). Use appropriate gauge wiring and an inline fuse for protection.
- Leak Check: Once all connections are made, slowly introduce water into the system and check for any leaks before applying full power.

7. Operating Instructions
The Aquapro 21847 pump is designed for user-friendly operation:
- Initial Start-up: Ensure all connections are secure and the water source is open. Apply 12V DC power to the pump. The pump will self-prime and begin to build pressure.
- Automatic Operation: The pump features an automatic 'on demand' pressure switch. It will turn on when a faucet or fixture is opened and the system pressure drops, and turn off when the fixture is closed and pressure is restored.
- Run-Dry Protection: The pump is designed to be run-dry safe, meaning it can operate without water for short periods without damage. However, prolonged dry running should be avoided.
- Check Valve Function: The built-in check valve prevents water from flowing back into the supply line, maintaining system pressure and allowing for seamless integration with city water connections if applicable.

8. Maintenance
Regular maintenance ensures the longevity and efficiency of your Aquapro pump:
- Strainer Cleaning: Periodically inspect and clean the inlet strainer to remove any accumulated debris. A clogged strainer can reduce pump performance and potentially cause damage.
- Winterization: In climates where freezing temperatures occur, drain all water from the pump and plumbing system to prevent ice damage.
- Connection Checks: Regularly inspect all water and electrical connections for tightness and signs of wear or corrosion.
9. Troubleshooting
If you encounter issues with your pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump runs but no water flows | No water in supply, clogged inlet strainer, air in system, kinked hose. | Check water supply, clean strainer, bleed air from system, straighten hoses. |
| Pump cycles on and off frequently | Small leak in system, pressure switch setting too low, partially clogged outlet. | Check for leaks, adjust pressure switch (if adjustable), clear outlet obstruction. |
| Low flow or pressure | Clogged strainer, low voltage, worn pump head. | Clean strainer, verify 12V power supply, inspect pump head for wear. |
| Pump does not turn on | No power, blown fuse, faulty wiring, seized motor. | Check power connections, replace fuse, inspect wiring, contact support if motor is seized. |
