4. Funzionalità del sistema
IL Webasto Air Top EVO 40 operates as a forced-air diesel heater. It draws in fresh air, heats it using a combustion process, and then circulates the warm air into the vehicle's interior. The system includes a glow plug for ignition, a fuel pump for precise fuel delivery, and a control unit to manage the heating process.
Figura 4.1: Sezione trasversale view of the air heating system, illustrating key internal components such as the glow plug, combustion chamber, heat exchanger, impellers, control unit, and various sensors.
Key functional components include:
- Heater Housing: Encloses all internal components.
- Combustion Air Blower: Fornisce aria per il processo di combustione.
- Tubular Combustion Chamber: Where fuel is ignited and burned.
- Scambiatore di calore: Transfers heat from the combustion gases to the circulating air without mixing.
- Hot Air Blower: Circulates the heated air into the vehicle.
- Unità di controllo: Manages all heater functions, including ignition, fuel delivery, and temperature regulation.
- Pompa del carburante: Delivers precise amounts of diesel fuel to the combustion chamber.
- Candeletta: Ignites the fuel-air mixture during startup.

5.2. Considerazioni generali sull'installazione
- Posizione di montaggio: Choose a dry, protected location, typically under the vehicle, in a storage compartment, or within the cabin, ensuring adequate clearance for air intake and exhaust.
- Rifornimento di carburante: Connect the fuel pump to the vehicle's diesel tank or a dedicated fuel tank. Ensure all fuel lines are securely fastened and free from leaks.
- Collegamento elettrico: Connect the heater to a 12V or 24V DC power source as specified for your model. Ensure proper fusing and wiring according to the provided wiring diagram.
- Condotti dell'aria: Install the warm air ducts to distribute heat effectively throughout the desired area. Ensure ducts are not kinked or obstructed.
- Sistema di scarico: Route the exhaust pipe safely away from flammable materials and passenger areas. Ensure proper sealing to prevent exhaust fumes from entering the vehicle.
- Presa d'aria di combustione: Ensure the combustion air intake is clear of obstructions and draws in fresh air from outside the vehicle.
6. Istruzioni per l'uso
Operare il Webasto Air Top EVO 40 is straightforward using the control unit. The specific control panel may vary, but general functions remain consistent.
Figura 6.1: Example di a Webasto control knob, typically used for turning the heater on/off and adjusting the desired temperature.
6.1. Avviamento del riscaldamento
- Assicurarsi che la batteria del veicolo sia adeguatamente carica e che ci sia carburante diesel a sufficienza.
- Turn the control knob or press the power button on your control panel to the 'ON' position or desired temperature setting.
- The heater will initiate a startup sequence, which includes a self-test, glow plug activation, and fuel pump priming. This process may take a few minutes.
- Once combustion is stable, warm air will begin to flow from the air outlets.
6.2. Regolazione della temperatura
Use the control knob or digital interface to set your desired temperature. The heater will automatically adjust its heat output to maintain the set temperature.
6.3. Spegnimento del riscaldamento
- Turn the control knob or press the power button to the 'OFF' position.
- The heater will enter a cool-down cycle to prevent overheating and clear the combustion chamber. Do not disconnect power during this cycle.
- Once the cool-down cycle is complete (indicated by the fan stopping), the heater is safely shut down.
