Nøkkelkomponenter:

• Innløpsport: For fuel supply from the tank.
• Uttaksport: For fuel delivery to the burner nozzle.
• Returport: For unused fuel to return to the tank.
• Pressure Gauge Port: For connecting a pressure gauge to monitor operating pressure.
• Pressure Regulating Valve: Adjusts the fuel pressure.
• Solenoid Valve Connection: For electrical control of fuel flow.
• Aksel: Connects to the burner motor for pump operation.

4. Oppsett og installasjon

Riktig installasjon er avgjørende for pumpens ytelse og levetid. Følg disse trinnene nøye:

1. Montering: Securely mount the pump to the burner motor flange using appropriate fasteners. Ensure the pump shaft aligns correctly with the motor coupling.
2. Drivstoffledningstilkoblinger:
   • Connect the fuel supply line from the tank to the pump's inlet port (marked 'P' or 'IN').
   • Connect the fuel line to the burner nozzle to the pump's outlet port (marked 'V' or 'OUT').
   • Connect the return line from the pump's return port to the fuel tank. Ensure the return line is submerged below the fuel level in the tank to prevent air ingress.
3. Montering av trykkmåler: Install a suitable pressure gauge into the designated port to monitor the operating pressure.
4. Solenoid Valve Wiring: Connect the solenoid valve according to the burner manufacturer's wiring diagram. Ensure correct polarity if specified.
5. Lekkasjekontroll: After all connections are made, visually inspect for any potential leaks.

5. Bruksanvisning

Once installed, follow these steps for initial startup and operation:

1. Grunning av pumpen:
   • Ensure the fuel tank has sufficient oil.
   • Open any shut-off valves in the fuel supply line.
   • Start the burner motor. The pump will begin to draw oil. It may take a few seconds for the pump to prime and for the pressure to stabilize.
   • If the pump does not prime within 30-60 seconds, check for air leaks in the suction line or ensure the tank has fuel.
2. Justering av trykk:
   • The pump features an adjustable pressure regulating valve. Use a suitable tool to turn the adjustment screw.
   • Turn clockwise to increase pressure, counter-clockwise to decrease pressure.
   • Monitor the pressure gauge while adjusting to achieve the desired operating pressure as specified by the burner manufacturer (typically between 7 and 25 bar for this model).
3. Solenoid Valve Operation: The integrated solenoid valve controls the immediate cut-off of fuel flow to the nozzle when the burner shuts down, preventing after-drip. Ensure it is functioning correctly during burner cycles.

6. Vedlikehold

Regular maintenance ensures optimal performance and extends the life of your SUNTEC oil pump. Always disconnect power to the burner before performing any maintenance.

• Rengjøring/utskifting av filter: The pump may contain an internal filter. Check the burner manufacturer's recommendations for filter maintenance. Clean or replace the filter periodically (e.g., annually or as needed based on fuel quality).
• Lekkasje inspeksjon: Regularly inspect all fuel lines and connections for signs of leaks. Tighten any loose connections.
• Generell rengjøring: Hold pumpens utside ren og fri for støv og rusk.
• Inspeksjon av aksel: Periodically check the pump shaft for any signs of wear or damage.
