Very disappointed with this unit. Purchased when house ac failed to cool a 225sq ' room. After running for 2 days room never cooled off even though unit was putting out cold air. Moved it to a 170 sq ' room with slightly better results. Currently it is mid day 85 degrees with 61% humidity out doors. Room temp is 78 degrees with 65% humidity. Temp of air comming out of the front  of the unit is around 69 degrees, measured vented outdoor is 125 dgrees as well as surface temp of exhaust duct. Manual is poorly documentated and does not agree with how the unit appears to be working. AC unit appears to dump removed moisture back into the room with a humidify cycle. Room temp and humity levels both increase.
