It has not been installed yet to be put into operation, so the comment is about the contents of the packaging.

You are purchasing an extractor with a 150mm outlet at the top. The accessories are inside the device and you need to remove the filters to find them (screws for installation, non-return flap, instruction manual). You can find the manual here: https://heinner.com/appliances/wp-content/uploads/sites/5/2023/12/manual_de_utilizare_HTCH-F660IX_614996020529a.pdf

The surrounding sheet metal is not very thick, there is no reinforcement at the points where the installation is done. However, when it was placed on a wall with 2 screws (I used my own stronger 6mm screws in D10 holes), it was fine. Initially, I was thinking of putting 2 brackets to support it from below, but I saw in more expensive models that they provided a supporting bracket from below, apart from the reinforced hanging mechanism, but it probably won't be necessary.

It seems to absorb just fine, I will update once it has been tested.
