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 5or 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.
