I bought a used Bosch and I am having the most difficult time trying to find out what happens with the air vent hose on the right side of the cabinet. I have looked at installation guides and the instructions state you do not to hook up the air vent. I don't know what do you do with the air vent if you don't hook it up I'm just not sure what to do with hose. If you don't hook it up, what happens to all the moisture from the air vent. I have had two appliance installation companies say they have never seen a air vent and do not have any idea what to do. :confused: Thank you. Annie
