and Attachment

8.6.3.1 Installation Location

It is advantageous to mount the dosing pump in a cool

location. The ambient temperature must never exceed

+20 °C during operation.

Dosing pump and fuel lines must not be installed in loca-

tions exposed to heat radiated by hot vehicle compo-

nents. A heat shield is to be provided as required.

8.6.3.2 Installation and Attachment

The dosing pump is to be attached with anti-vibration

mounts. The installation location is limited according to

Fig. 806 to ensure sufficient self-venting capability. Due

to the danger of corrosion the plug connection between

dosing pump and dosing pump cable loom may only use

Webasto original parts.

vertically if possible, however at most horizontally (check

flow direction).
