One thing I forgot was the exhaust tube. DH does sheetmetal for a living, the intricate pieces. We took out a screen in the kitchen window, DH made a sheet of metal that size to fit with the hole and slides that the hose slips into with a tight fit. Looks great! Have a screen attached to hole so no bugs can get in. When not in use we close the slat windows. Never had problems with water coming in or cool air escaping. Condensation hose to the sink.
