1.6HOW TO OPERATE DEHUMIDIFIER
1.6.1HOW DOES THE DEHUMIDIFIER WORK?
Moist, humid air is drawn over a cold refrigerated dehumidifying coil. Moisture in the air condenses on this coil and drains into a bucket (or through the bucket into a hose and drain).
Dry, clean air is drawn over the condenser where it is actually heated several degrees and discharged out the rear grill into the room. (See Figure 4)
■It is normal for the surrounding air to become
slightly warmer as the dehumidifier operates.
This warming effect further reduces the relative humidity of the surrounding air.
1.6.2 LOCATION FOR THE DEHUMIDIFIER
Allow at least 12 inches of space on all sides of the unit for good air circulation. (See Figure 5)
■The dehumidifier must be operated in an enclosed area to be most effective.
■Close all doors, windows and other outside
openings to the room.
Place the dehumidifier in a location that does not restrict air flow into the front grille or out the rear grille.
The operation of dehumidifier 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.

1.6.3 MICRO SWITCH
The micro switch assembly, which is located on the drain pan of inside unit, automatically shuts off the dehumidifier when the bucket is full (note, the Auto Shut Off lights, to indicate bucket must be emptied). The bucket replaces in its place, the unit again turns itself on.
1.6.4 AUTO DEFROST
When frost builds up on the cooling coils, the unit will automatically cycle off until the frost disappears. The fan continues to run.
NOTE: The unit will not operate satisfactorily if the room temperature is below 65˚F(18˚C). If the dehumidifier is operated in low temperature conditions frost can form in the evaporator coil and the unit will cycle ON/OFF repeatedly. In this case, please check your room temperature conditions and stop the unit.
NOTE: The low temperature operation feature in the DH504EL, DH50EL and DH65EL models will continuously cycle up to a temperature of 42°F(6°C).
