This model is ideal for ceiling installation when there is insufficient above ceiling clearance (less than 9 1/4) for a flush-mounted ceiling cassette, or if you prefer not to have a wall-mounted model for structural or aesthetic reasons. The indoor air handler measures 65 3/8" wide x 9 1/2"high x 27 1/2" deep and can be positioned anywhere on the ceiling for maximum effectiveness. Operate the unit with the included remote or wired optional wall controller.
