Hello people, the work does not want to give me any information: how to remove the roof hood of the Truma Aventa roof climate? Guggenheim da: https://www.truma.com/…/ I would have set the picture here, but I have concerns about legal things. So: I want to remove the lid at this climate to clean the heat exchangers. The work does not give out any spare parts catalogues or other information….;o(Thank you in advance Hans
