Question about ecofort ecoQ CoolAir 7

The text says: Benefit from the top value for money and save an additional CHF 50 because the required window seal is already included in the scope of delivery.

Is that true? Or do I have to buy something extra?

Hello! Yes, you have to use both because the self evaporating system (which evacuates through the exhaust hose) is not switched off in dehumidifying mode, Don't forget to turn the unit off before installing the drain hose😉!

Then connect the plastic hose (supplied) at the back and the other end to a large water container. You also need to use the air exhaust hose.
