4. Operating Instructions
Once installed, the Suntec A2VA-7116 pump requires proper priming and pressure adjustment for optimal performance.
4.1 Priming the Pump
- Restore Power: Turn on the main power supply to the oil burner system.
- Bleed Air: Open the bleed valve on the pump. Start the oil burner motor. Allow the pump to run until a steady stream of air-free fuel flows from the bleed valve.
- Close Bleed Valve: Once fuel flows without air bubbles, close the bleed valve securely.
4.2 Pressure Adjustment
- The pump is factory set at 100 PSI.
- The pressure can be adjusted between 100 and 150 PSI using the pressure regulating screw.
- Use a pressure gauge connected to the designated port to monitor the pressure during adjustment.
- Turn the adjustment screw clockwise to increase pressure and counter-clockwise to decrease pressure.
- Always refer to your oil burner manufacturer's specifications for the recommended operating pressure.
5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your Suntec oil burner pump.
- Fuel Quality: Ensure that clean fuel is consistently supplied to the pump. Contaminants can significantly reduce pump life and performance.
- Filter Replacement: Regularly check and replace the fuel filter in your system as recommended by the oil burner manufacturer. A clogged filter can strain the pump.
- Leak Inspection: Periodically inspect all fuel lines and connections for any signs of leaks. Address any leaks immediately.
- Professional Inspection: It is recommended to have the entire oil burner system, including the pump, inspected annually by a qualified technician.
6. Troubleshooting
This section provides guidance for common issues. For complex problems, contact a qualified service technician.
| Problem | Possible Cause | Solution |
|---|---|---|
