Webasto Thermo Top Evo - B Operating Instructions

Dear Webasto Customer,

Thank you for choosing the Webasto Thermo Top Evo Water Heater. 

We hope you will enjoy many years of additional comfort during your travels with it.

The Thermo Top Evo heater is used in conjunction with the original vehicle heating system 

– to heat the passenger compartment, 

– to defrost the vehicle windows and 

– to preheat water-cooled engines. 

We presume that the principle and mode of operation of your new heater has been explained 

to your complete satisfaction by the workshop/service centre which installed the heater. In 

these operating instructions we would like to once again provide you with an overview of the 

safe use of the Thermo Top Evo heater. 

To become familiar with and understand all functions of the heater, you must 

read these operating instructions carefully. 

Then you can be sure that you can use all functions to your satisfaction and 

feel completely comfortable and safe. 

If you should loose these instructions, please contact an authorised Webasto
