We bought the unit as "open box" with NO manual. Can't figure out how to drain the water which leaks out overnight and pools under the unit. Exhaust hose is attached and a clear plastic small hose also, which runs from the rear of the unit inside the exhaust hose. Is there a "well" or water tray inside which we cannot find? Model is MF8000E.Azny helpful advice would be most apprciated, thanks!
