Has a kit with it. Exactly as illustrated in the video and manual. This means that for bottom hung windows you have to order a separate kit (somewhere). The kit supplied is only designed for sliding windows (horizontal or vertical).

Something like that is included, but it's a real mess with all monobloc air conditioners. You would actually have to put a window seal on the hose so that warm air can't flow directly into the room through the hose. But then you have to open a window slightly in another part of the flat, because blowing the hot exhaust air out of the flat creates a negative pressure. Super not efficient, only a split air conditioner would offer a better solution, but as a tenant you can't usually install them.
