CHOOSING A PROPER LOCATION

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.

 Place the dehumidifier on a

smooth, level floor strong

enough to support the unit with

a full bucket of water.

 Allow at least 12-18 inches of air

space on all sides of the unit for

good air circulation.

 Place the dehumidifier in an

area where the temperature will

not fall below 41°F (5°C). The

coils can frost over at

temperatures below 41°F, which

may reduce performance.

 Use the dehumidifier in cooking,

laundry, bathing and

dishwashing areas that have

excessive moisture. NOTE:

Place the dehumidifier away

from the clothes dryer.

 Use the dehumidifier to reduce moisture where books and/or valuables are stored.

 Use the dehumidifier in a basement to help prevent moisture damage.

 The dehumidifier must be operated in an enclosed area to be most effective.

 Close all doors, windows and other outside openings to the room.

 NOTE: The dehumidifier has rollers to aid in placement, but it should only be rolled on

smooth, flat surfaces. Do not attempt to roll the dehumidifier on carpet or over objects.
