The Amcor PLM portable air conditioners are designed to condition average-sized rooms ranging from 300 to 500 sq. ft. Patented Evaporative Booster Technology: During the cooling process, water is extracted from the air as it passes through the unit. Most of this water is used to cool the unit and make it run more efficiently. This unit has a built-in water tank (not removable) with a drain outlet. When the tank fills, the compressor stops running. This indicates that the tank should be emptied. Included with the unit is a window mounted exhaust kit. AC must be vented via exhaust hose and window kit (included).
