This button controls the humidity in the room e Press button to raise the humidity setting Press gt button to lower the humidity setting The humidity setting can be set to a permanent On setting or to a specific humidity setting between 3596 and 7096 in 596 increments e On setting Dehumidifier runs continuously regardless of humidity condition 3596 7096 setting Dehumidifier runs on and off according to surrounding humidity conditions SE Auto Restart Once power is restored after a power outage the unit returns to its previous operation setting after a 2 minute delay The fan runs immediately when the power is restored 1 5 HOW TO OPERATE DEHUMIDIFIER 1 5 1 HOW DOES THE DEHUMIDIFIER WORK Condenser Moist humid air is drawn over a cold refrigerated Motor Evaporator dehumidifying coil Moisture in the air condenses on this Fan 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 front grille into the room See Figure 3 B t 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 Figure 3 1 5 2 LOCATION FOR THE DEHUMIDIFIER connection Allow at least 12 inches of space on all sides of the unit for good air circulation

8. See Figure 4 The dehumidifier must be operated in an enclosed area to be most effective E 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 rear coil or out the front 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 Figure 4 1 5 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 5 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 is designed to be operated at temperature above 65 F 18 C in normal condition If the dehumidifier is operated in low temperature conditions the temperature and humidity conditions of room are low some frost can be formed in its evaporator coil and the unit will be operated ON OFF repeatedly In this case please check on your room temperature condition and stop the unit 1 5 5 HUNIDITY CONTROLLER The humidity control can be set On or 35 70 RH Relative Humidity for normal operation
