User Manual GE AEM24DQL1 230 Volt Electronic Room Air Conditioner

he window air conditioners no longer have a drain hole or drain plug. You will not see condensate water dripping like you may have been used to seeing in the past. Currently, all room air conditioners have a "slinger ring" around the rear fan blade. This ring is designed to pick water up off the bottom of the pan and sling it on to the condenser coils, helping in the cooling process and cutting down on the chance of the air conditioner dripping.
During very hot and humid days, the air conditioner may permit excess water to pass through the rear and overflow from the back of the base pan outdoors. This is considered normal. It is correct to have the unit slightly tilted to the outside when installed in the window.

Yes, this unit is designed to be installed either in a window or through the wall. There are no additional accessories needed to install this unit through the wall.
