| Install | The permanently attached hose-in-hose duct telescopes from 13 to 48 inches, and the five-panel window kit spans roughly 20 to 48 inches without cutting, with generous weather stripping included. It works in hung and sliding windows; sliding glass doors need a third-party tall panel. In cooling mode the unit is self-evaporative and exhausts moisture automatically — you only break out the included drain hose in very humid climates or dehumidify mode. Budget help for stairs: it's a bulky 75-pound tower. | A single wide exhaust hose connects to De'Longhi's slider-style window bracket, which fits most hung and sliding windows and installs in minutes; it's one of the simpler kits in the class, though sealing wide openings takes extra foam. Condensate is recycled and exhausted automatically in cooling mode, with a drain plug for dehumidify duty. The catch is mass: at 83 pounds this is the heaviest unit here, and the recessed handles and casters only help on one level — treat it as semi-permanent. |
