"****" will stop flashing and turn to show the actual room humidity instead.
-When the humidity level exceeds the set humidity, the dehumidifier will automatically stop
working, while the humidity level falls below the set humidity, it will automatically start
working again.

3.Instruction for Clothes-Dryer Mode
The dehumidifier can be used for drying clothes in rainy weather.
Step 1.
Hang the washed clothes in a small space such as a cloakroom, bathroom,
or storage room.
Notice: Keep the unit away from the water drip from the washed clothes.
Step 2.
Open the dehumidifier and set the humidity level at 30% RH. It is suggested to let
the air outlet of the dehumidifier blow air to the clothes directly.
1. The drying effect will vary from the thickness of clothes, the number of clothes,
and the size of the drying room. Theoretically, the effect will be better when
clothes are few, thin and the room is small.
2.The drying process would take 3 - 8 hours, thus, setting the machine to the
continuous drainage mode is more suggested when drying clothes.

4. Error&Protection Code
Fault phenomenon
The humidity always shows "25%RH" (there is a big difference from the actual humidity)
The humidity always shows "99%RH" (there is a big difference from the actual humidity)
Analysis of causes
The humidity sensor failure?
1. There is water on the surface of the humidity sensor?
2. The humidity sensor failure?
Processing Method
Set the humidity to 30%RH, if the dehumidifier can still continue to work, the
machine can be used normally.
Repair and replace the humidity sensor.
If the dehumidifier is not affected and can continue to work, the machine can be
used normally.
please let the dehumidifier keeps working for a period of time, after the water on
the surface of the humidity sensor is removed, it will return to work normally.
Repair and replace the humidity sensor.
Notice:
When an error happened, there will be an error code flashes on the display. If
there is more than one error, each error code will be displayed in turn, if there is
only one error, the error code and the current humidity value will be displayed
alternately.

5. Empty the Water Tank
08
There are two ways to remove collected water.
Use the water tank
When the water tank is already full, the Full Tank Alert indicator light will turn on,

Ways to Empty the Water Tank

Float
Water tank cover
09
Notices:
Do not remove the float from the water tank. If the float in the water tank is remov
ed, the sensor may not be able to determine the water level stored in the tank
properly which may lead to a water overflow leak from the water tank.
If the water tank is dirty, just use cold water or warm water to clean it. Do not use
detergent, steel wool, chemically treated dust cloth, gasoline, benzene, thinner,
or other solvents. Otherwise, it may damage the water tank and cause it to leak.
When placing back the water tank, use your hands to press the tank back in its
place. If the water tank is not placed properly, sensors or protections from water
overflow may not operate as expected.
