1.6.1 HOW 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 front grille into the room.
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.
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 rear coil or out the front grille.
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.
Humidity Control
When you first use the dehumidifier, turn the humidity control to 5 or 6. If you still have moisture, turn the humidity control to a higher setting. MAX is the highest setting.
When excess moisture and dampness odors are gone, adjust the control to a lower setting. Use the dehumidifier as long as excess moisture is present.
Fan Speed
The fan control adjusts the fan speed. Set the fan control to HIGH for maximum moisture removal. When the humidity has been reduced and quiet operation is preferred, set the fan control to LOW.

1.6 HOW TO OPERATE DEHUMIDIFIER
1.5 CONTROL
Glows when the bucket is ready to be emptied, or when the bucket is removed or not replaced in the proper position.
The Water Level Control Switch shuts off the dehumidifier when the bucket is full, or when the bucket is removed or not replaced in the proper position.
Auto Shut-Off
1.6.5 HUMIDISTAT
Humidistat controls constant relative humidity in the room automatically.
When the relative humidity in the room increases to the selected level, the dehumidifier starts automatically. And the relative humidity drops to the selected level, the dehumidifier stops automatically.
When the first using the dehumidifier, it is recommended, for the first three or four days, to operate the unit with the humidistat control set to MAX. At this setting, the unit will run continuously.
When the sweating has stopped and the dampness odors have gone, it is preferable to select the humidistat position that will best suit local conditions.
The relative humidity range it can control is from 20 % to 80%. (See Figure 3)
NOTE: The relative humidity at the number is the
approximate value.
1.6.6 DRIER (For some models)
Dryer is used to prevent capillary blockage from moisture in the refrigerant system and H/E, condenser and evaporator. Also, dryer is used to remove corrosion of the components.
NOTE: When dryer is replaced, proper injection to
capillary is needed. On opening the dryer, it should be welded instantly. The oxidization of dryer inside and all tubes inside after welding can be prevented.

1.6.3 MICRO SWITCH
The micro switch assembly, which is located on the barrier 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 compressor will cycle off until the frost disappears. The fan continues to run.
NOTE: This unit is designed to be operated at temperatures above 65°F(18°C). 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.
