Webasto will take you step by step through the installation process to ensure successful operation for years to come.
The installation must be performed in accordance with the installation instructions provided in this manual.
IMPORTANT! The proposed heater installation must be approved by Webasto Thermosystems.
5.2 Installation Location
The heater and circulation pump are to be integrated into the coolant system (or into a separate heating circuit, if
applicable) of the vehicle. The heater should be installed as low as possible in the coolant system to assure static
bleeding of the heater and the circulating pump.

typically towards the rear of the vehicle. The heater may also be located in the engine compartment. The
installation enclosure must provide adequate ventilation for combustion air requirements [4 in² (20 cm²)]. When
installing the heater, make certain that the clearances required for accessing the unit for servicing are observed (e.g.
removal of the combustion chamber). See figure 4-1, page 4-2.
