| Install | TechGearLab rated this one of the easiest portables to install thanks to a clever window kit with a built-in lock mechanism that snaps together without tools — most people are running in ten minutes. The single exhaust hose and slider panel fit standard double-hung and sliding windows, but no foam weather stripping is included, so buy a roll of foam tape to seal the gaps. Condensate mostly self-evaporates out the hose in cool mode; a bottom drain plug handles dehumidifier mode or very humid days. At 52 lbs with smooth casters it's one of the easier units to move seasonally. | Comes with a basic slider window kit (two panel pieces, fewer than most competitors) and a single 5.5-inch exhaust hose that extends to about 61 inches, so plan on a window within five feet of where the unit sits. Auto-evaporation handles most condensate in cool mode, exhausting moisture out the hose, so you rarely empty a tank in normal use. In dehumidifier mode or very humid climates you'll want to attach the included drain hose to a floor drain or bucket. The minimal weather stripping means you should buy extra foam tape to seal the window panel properly. |
