5. Setup
5.1 Pre-Installation Checks
- Verify that the oil pump model matches the requirements of your burner system.
- Ensure all necessary fittings and a compatible solenoid valve are available.
- Inspect the pump for any visible damage before installation.
5.2 Mounting
Mount the oil pump securely to the burner assembly or a stable surface, ensuring it is level and free from excessive vibration. Refer to your burner's specific mounting instructions for optimal placement.
5.3 Fuel Line Connection
The SUNTEC AN series pump supports both single-pipe and double-pipe oil supply systems:
- Single-Pipe System: Connect the fuel supply line to the 'V' (vacuum/suction) port. The return line port should be plugged or configured as per the burner manufacturer's instructions.
- Double-Pipe System: Connect the fuel supply line to the 'V' port and the return line to the designated return port. Ensure the bypass plug is correctly installed for a double-pipe system.
Connect the pressure line from the 'P' (pressure) port to the burner's nozzle assembly. All connections must be tight to prevent leaks.
5.4 Solenoid Valve Integration
An external solenoid valve is required to control the fuel flow to the burner. Install the solenoid valve in the fuel line between the pump's pressure port and the burner nozzle. Wire the solenoid valve according to the burner's electrical diagram and local electrical codes.
5.5 Priming the Pump
After installation, it is crucial to prime the oil pump to remove any air from the fuel lines. Follow the priming procedure outlined in your burner's instruction manual. This typically involves running the pump for a short period until a steady flow of fuel is observed at the nozzle or bleed port.
6. Operating Instructions
Once the SUNTEC oil pump is correctly installed and primed, its operation is integrated with the overall burner control system. The pump will activate when the burner calls for heat, drawing fuel from the tank and delivering it under pressure to the nozzle.
- Ensure the fuel tank has an adequate supply of the correct type of fuel (kerosene or diesel).
- The pressure cut-off regulating valve maintains a consistent fuel pressure for optimal burner performance.
- The external solenoid valve will open and close to control the start and stop of fuel delivery to the burner.
Monitor the burner's performance and fuel pressure regularly to ensure efficient and safe operation.
7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your SUNTEC oil pump.
- Annual Inspection: Have the pump inspected annually by a qualified technician.
- Filter Replacement: Check and replace the fuel filter(s) in your system as recommended by the burner manufacturer. A clogged filter can strain the pump and reduce performance.
- Leak Check: Periodically inspect all fuel lines and connections for any signs of leaks. Tighten connections as needed.
- Cleanliness: Keep the exterior of the pump clean and free from dust, dirt, and oil residue.
- Pressure Check: Verify the fuel pressure output using a pressure gauge to ensure it is within the recommended range for your burner.
8. Troubleshooting
This section provides general guidance for common issues. For complex problems, consult a qualified technician.
8.1 No Fuel Delivery
- Check Fuel Level: Ensure there is sufficient fuel in the tank.
- Check Power: Verify the pump is receiving power and the burner control system is functioning.
- Clogged Filter: Inspect and replace fuel filters if they are dirty or clogged.
- Air in Lines: Re-prime the pump to remove any trapped air.
- Solenoid Valve: Ensure the external solenoid valve is opening correctly when the burner calls for heat.
8.2 Low Fuel Pressure
- Clogged Filter: A partially clogged filter can restrict flow and reduce pressure.
- Air Leak: Check for air leaks in the suction line, which can cause cavitation and low pressure.
- Pump Wear: If the pump is old, internal wear can lead to reduced pressure. Professional inspection may be required.
8.3 Fuel Leaks
- Inspect Connections: Carefully check all fittings and connections for tightness.
- Damaged Seals: If leaks persist, internal seals or gaskets within the pump may be damaged and require professional repair or pump replacement.
9. User Tips
- For optimal performance and longevity, always use clean fuel free from contaminants.
- Consider installing a high-quality fuel filter upstream of the pump to protect it from particulates.
- If converting between single-pipe and double-pipe systems, ensure the bypass plug is correctly configured for the chosen setup.
