User Manual Haier QPHD10AXLB Portable Air Conditioner

Part of the cooling process is removing humidity from the room. When first installed or after the unit has not been used in awhile, it is normal for the tank to fill up quickly and require more frequent emptying. Even once an hour can be normal.

Portable AC units must be ventilated. They produce hot air that needs to be exhausted through a hose, so they should be placed near a window.
