Open Box. Item appears to be in unused, excellent condition. It appears there was an attempted installation of the window slider and the intake/exhaust hoses. Window slider has marks and scuffs. Intake filter is like new; carbon filter is unopened. Factory tape is still on unit. Remote and AC power on. When vent is turned to the OPEN position, cold air comes out front and warm air out back. Original box is somewhat damaged and retaped, especially on the bottom; this does not affect product. See images for item description. Everything included with the item can be seen in the images.
