Proper installation is crucial for the safe and efficient operation of your diesel air heater. It is recommended that installation be performed by a qualified professional if you are unsure about any steps.

Orientacions generals:

• Ubicació: Choose a dry, well-ventilated area for installation. Ensure sufficient clearance around the heater for air intake and exhaust.
• Muntatge: Securely mount the heater using the provided fixture accessories. Ensure it is stable and cannot vibrate excessively during operation.
• Connexió de combustible: Connect the fuel line from the fuel tank (for split types) or ensure the internal tank (for all-in-one types) is accessible for filling. Use only diesel fuel.
• Connexió elèctrica: Connect the heater to a 12V or 24V DC power source, depending on your model and vehicle's electrical system. Ensure correct polarity and secure connections to prevent short circuits. Some all-in-one models may support 240V AC with an appropriate adapter (not included).
• Air Intake & Exhaust: Install the intake and exhaust pipes. The exhaust pipe must be routed safely away from flammable materials and living spaces, ensuring no exhaust gases can enter the vehicle or cabin. A silencer is included with some models to reduce noise.

Specific Model Considerations:

• All-in-One Type (W1-S, L1-S): These units are self-contained. Ensure the internal fuel tank is filled and the DC battery power cable is connected.
• Split Type (F1-S, F1-N): These units require external connection of the oil pump, fuel tank, and separate air intake/outlet pipes. Follow the diagrams provided in your user manual for correct assembly.
