A:Answer Hello Mif11,
During air conditioning mode, most of the water created by humidity will be recycled and sprinkled over the evaporator coils to cool the unit down. Most of this water will be evaporated. Only during high humidity periods where condensate water will be created faster than it can evaporate, the excess will run into the internal bucket and the unit will turn off and the red light will turn on to let you know that it is required to drain it.
