A:AnswerThere is nothing that needs to be emptied unless you put the unit in Dry mode. Dry mode is a dehumidifier mode and a hose needs to be attached and routed out a window. The condensation from the AC cooling is self evaporating.
A:AnswerYes, but it must be noted you have to vent the unit to the outside with about an 8" hose and ducting provided or make one for your application. The unit will cool down a 20x30 Sq Ft. room ins short order depending on the temp and humidity levels.
