Installation location and installation position

Body sections and any other components in the vicinity of the heater must
be protected from excessive heat and the possibility of fuel or oil
contamination.
(Requirement from ECE-R 122, Point 5.3.2.1.).
The heater shall not constitute a risk of fire, even in the case of overheating.
This requirement shall be deemed to be met if the installation ensures an
adequate distance to all parts and suitable ventilation, by the use of fire
resistant materials or by the use of heat shields.
(Requirement from ECE-R 122, Point 5.3.2.2.).
The heater must not be installed in the vehicle interior. The heater is
preferably installed in the engine compartment, i.e. in the area between the
wheel well and the front bumper.
Installation should be carried out as low as possible to ensure automatic
bleeding of the heater and circulation pump. This is particularly important as
the circulation pump is not self-priming.
The openings of the heat exchanger may not face downward in
any installation position.
Fig. 1 shows the permissible installation position of the heater.
For the position of the heat exchanger opening of the heater, see Fig. 2.
For dimensions of heater, see chapter 14, "Technical Data".
