5. Operating the Parking Heater
This installation kit provides the necessary components to integrate the Webasto Thermo Top Evo 4 parking heater. The operation of the heater itself is controlled via its dedicated control unit (e.g., MultiControl, Telestart, ThermoCall), which is typically purchased separately or included with the main heater unit.
Please refer to the separate operating manual provided with your Webasto Thermo Top Evo 4 parking heater control unit for detailed instructions on how to:
- Start and stop the heater manually.
- Program heating times.
- Adjust heating duration and temperature settings.
- Utilize remote control or smartphone app functions (if applicable).
Ensure the vehicle's fuel tank has sufficient fuel for heater operation. The heater draws a small amount of fuel directly from the vehicle's tank.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Webasto parking heater system. While this kit itself requires minimal maintenance, the integrated heater unit does.
- Annual Inspection: It is recommended to have the entire parking heater system, including the components from this installation kit, inspected annually by an authorized Webasto service center. This inspection should cover:
- Checking all fuel and coolant connections for leaks.
- Inspecting the exhaust system for damage or blockages.
- Verifying the integrity of electrical connections and wiring.
- Checking the combustion air intake for obstructions.
- System Operation: Operate the parking heater for approximately 10-15 minutes once a month, even during warmer periods, to prevent components from seizing and to ensure proper function.
- Cleaning: Keep the area around the heater and its air intake/exhaust free from dirt, leaves, and other debris.
Do not attempt to repair or modify the heater or its components yourself. Always consult an authorized Webasto service partner for any repairs or servicing.
