Get all the cooling performance you expect from LG in a more compact size. The smaller profile lets you install it in a window opening as small as 12” in height—and makes it easier to carry and install. Enjoy the view outside without a big bulky air conditioner getting in the way. Keep small children from randomly pressing buttons that can affect performance or cause possible damage. When Child Lock is enabled, “CL” appears on the display and adjustments cannot be made on the control panel, only through the remote control or ThinQ® app. The Child Lock setting is retained even if the unit is unplugged or loses power so you can be comfortable—and confident.
