4. Setup and Installation
Proper installation is crucial for pump performance and longevity.
4.1 Mounting
- Mount the pump in a dry, well-ventilated area.
- Secure the pump to a solid surface using the integrated mounting tabs.
- Ensure the pump is mounted in a position that allows for easy access for maintenance and inspection.
4.2 Plumbing
- Use appropriate fittings (2 fittings included) for your application.
- Connect the inlet hose to the pump's inlet port (indicated by 'FLOW' arrow).
- Connect the outlet hose to the pump's outlet port.
- Ensure all plumbing connections are tight to prevent leaks and air ingress.
- Install a filter on the inlet side to protect the pump from debris.
4.3 Electrical Connection
- This pump operates on Corded Electric power. Refer to the pump label for specific voltage requirements.
- Connect the pump to a fused power supply.
- Ensure correct polarity for DC models.
- All electrical connections should be made by a qualified professional and comply with local codes.
5. Operating Instructions
The 23A Series is an automatic demand pump, meaning it will turn on and off based on system pressure.
- Priming: Once plumbing and electrical connections are complete, open a faucet or valve on the discharge side to allow air to escape. Turn on the power to the pump. The pump will begin to self-prime. Once a steady stream of water flows from the open faucet, close it. The pump will build pressure and shut off.
- Automatic Operation: The pump will automatically turn on when a demand for water is detected (e.g., opening a faucet) and turn off when the demand ceases and system pressure is restored.
- Dry Run: The pump is capable of dry running without damage, but continuous dry running is not recommended.
6. Maintenance
Regular maintenance ensures optimal performance and extends the pump's lifespan.
- Inspect Connections: Periodically check all plumbing and electrical connections for tightness and signs of wear.
- Clean Inlet Filter: If an inlet filter is installed, clean it regularly to prevent debris from entering the pump.
- Winterization: In freezing conditions, drain all water from the pump and plumbing system to prevent damage. Run non-toxic RV antifreeze through the system if necessary.
- General Cleaning: Keep the exterior of the pump clean and free from dirt and debris.
7. Troubleshooting
Refer to the following table for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on | No power; Blown fuse; Loose wiring; Faulty pressure switch | Check power supply; Replace fuse; Secure wiring; Contact support if switch is faulty. |
| Low flow or no pressure | Clogged inlet filter; Air leak in suction line; Restricted discharge line; Low voltage | Clean filter; Check all suction connections; Clear discharge line; Verify voltage. |
| Pump runs continuously | Water leak in system; Air leak in suction line; Faulty pressure switch | Check for leaks in plumbing; Check suction connections; Contact support if switch is faulty. |
| Noisy operation | Air in system; Loose mounting; Debris in pump head | Bleed air from system; Tighten mounting screws; Inspect pump head for foreign objects. |
