IMPORTANT
The exhaust-temperature sensor cable is designed as a high-
temperature-resistant line.
The material is resistant to continuous effects of tempera-
tures of up to 185 °C, however it is sensitive to external
mechanical influences.
Before the final decision about specification of the heater
installation location, we recommend conducting an analysis
for the possible risk of damage to the cable due to stone
impact. If stone impact is possible at the heater installation
location, then precautionary measures must be taken for
direct protection of the exhaust temperature sensor cable,
e.g. with suitable covers.
