POSITIONING THE UNIT
A dehumidifier operating in a basement will have little or no effect in drying an adjacent
enclosed storage area, such as a closet, unless there is adequate circulation of air in and
out of the area.
•Do not use outdoors.
•This dehumidifier is intended for indoor
residential applications only. This
dehumidifier is not recommended for
commercial or industrial applications.
