4.2 Raccordements des conduites de carburant
Connect the fuel lines as follows:
- Inlet (Suction) Line: Connect the fuel supply line to the designated inlet port. Ensure a tight, leak-free connection.
- Nozzle Line (Pressure): Connect the line leading to the burner nozzle to the pressure port (marked 'P' on some models).
- Ligne de retour : If applicable, connect the return line to the return port (marked 'V' on some models) to send excess fuel back to the tank. For single-pipe systems, the return port must be plugged.
4.3 Connexions électriques
Connect the pump's electrical terminals to the burner control system according to the burner manufacturer's wiring diagram. Ensure correct voltage and polarity. All electrical work must comply with local codes and regulations.
4.4 Amorçage de la pompe
After installation, the pump must be primed to remove air from the fuel lines. This is typically done by running the burner for a short period until a steady flame is established. Some pumps may have a bleed screw for manual air removal.
5. Mode d'emploi
Once installed and primed, the DANFOSS BFP 21R3 pump operates automatically in conjunction with the burner control system. The pump maintains the required fuel pressure for efficient combustion.
5.1 Réglage de la pression
The pump's pressure can be adjusted via a pressure regulating screw, typically located on the pump body. Use a pressure gauge to set the desired operating pressure as specified by the burner manufacturer. Turn the screw clockwise to increase pressure and counter-clockwise to decrease pressure.
6. Entretien
Regular maintenance ensures optimal performance and extends the life of the pump.
6.1 Contrôles de routine
- Inspect fuel lines for leaks, cracks, or damage.
- Vérifiez le serrage et l'absence de corrosion des connexions électriques.
- Soyez attentif aux bruits inhabituels pendant le fonctionnement, car ils peuvent indiquer un problème.
6.2 Remplacement du filtre
The pump typically contains an internal filter that should be inspected and replaced periodically, usually annually or as recommended by the burner manufacturer. A clogged filter can restrict fuel flow and reduce pump performance.
