I have this model and another smaller model. Started this one with Auto setting and soon discovered that we had to attach the clear hose to let the unit drain water. No big deal. Bought the another smaller unit and started it only in cool mode and did not hook up hose and it does not need a waterdrain. It cools without having water drain. This unit still drains tons of water even after turning on only cool mode. I'm talking many gallons per day. It fills a 2 gallon bucket in 7 hours. It's going to ruin my floors! Don't understand why we can't get it to quit dry mode?
