Precautions For User

• Use the machine on flat firm floor inside room. Don't put objects in front of air inlet for better efficiency.
• Don't use the machine in the environment with combustible, explosive, corrosive air or dusty. Do keep at least 50cm space for ventilation around the machine.
• Please use the machine away from heat for less power consumption.
• The working temperature range of machine is 5 ℃ ~ 38 ℃. The protection of compressor will be acted if use it in the environment temperature higher than 38 ℃ and stop running automatically, it will reduce the working life of the machine. Below 5 ℃, absolute humidity of the environment is quite low, do not use the machine if not necessary.
• Do make sure to leave at least 50 cm from wall to air inlet and at least 50 cm from wall to air outlet when the machine used against a wall, otherwise it will affect the dehumidifying effect or cause machine failure.
• Do not incline the machine exceed 45 degrees in moving or installation. Do correctly assemble the drain pipe for drainage.
• In the low temperature condition, the defrosted water will be frozen gradually at the outlet, please don’t open the machine until all the ice melted to avoid water overflow to room from water collector.
• Please clean the filter net regularly in using machine, make necessary isolation measure when use in the dusty environment to avoid malfunction and raise the working life.
• Don’t cut off the power or pull out plug when machine running. Don’t damage the power line or make any change.
• Don’t put fingers or sticks into the air outlet.
• Don’t do any change of machine unless guiding by our technicians.

Control Panel

1. “On/Off”
   On: press the key into opening mode. Off: press the key into closing mode.
2. “Humidity Hours +”
   Press the key “set” first then press the humidity value up with 1%RH scale in running mode. Press the key “set” first then press hours up with 1 hour scale in timed on/offsetting mode. During operation, each press will increase the required humidity level by 1%. In timer mode, each press will increase the on / off time of the device by 1 hour.
3. “Humidity Hours-”
   Press the key “set” first then press the humidity value down with 1%RH scale in running mode.Press the key “set” first then press the hours down with 1 hour scale in timed on/offsetting mode. During operation, each press will decrease the required humidity level by 1%.
4. “Room RH”
   Current ambient humidity display when in standby mode and running mode. Blinking when at humidity setting mode.
5. “Set RH”
   Display when in the humidity setting mode
6. “Coil ℉”
   Display the temperature of coil
7. “Room ℉”
   Display the temperature of ambient
8. “Dehumidifying”
   Blinking when compressor is working.
9. “Water drop icon”
   Blinking when the fan is working.
10. “Defrost”
    Blinking when the machine frosting
11. “Tankfull”
    Blinking when tank is full or pull out the tank.
12. “Timed On / Timed Off”
    Blinking when in the timed on/offsetting mode

Fault Code Indication

Common Faults Removing

1. When the malfunction can not be removed and recognized, please contact the supplier for maintenance service, do not attempt to disassemble the machine to repair without guide.
2. When dehumidifier is running or stopping, you will hear the sound of refrigeration cycle, it is a normal phenomenon, not a fault.
3. Discharge hot air from outlet is a normal phenomenon.

Schematic & Circuit Diagram

Dehumidification principle
Under the condition of normal startup → through the operation of the fan → moist air is sucked in from the air inlet → through the evaporator → the evaporator absorbs the moisture in the air on the aluminum sheet → becomes dry air → dissipates heat through the condenser → blows out from the air outlet.

Refrigeration principle
The high temperature and high pressure gas is discharged through the operation of the compressor → the exhaust port → enters the condenser for cooling → becomes a low temperature and high pressure gas → intercepts the flow through the capillary → becomes a low temperature and low pressure liquid → evaporates and absorbs heat through the evaporator → returns to the compressor and becomes a low temperature and low pressure gas.

Protection Function

A. When the dehumidifier is automatically frost, the compressor stops running, the fan continues to run, the frost lights are on, and the running lights are on.
B. After the compressor delays the protection function, the compressor is automatically delayed after 3 minutes.
C. When the temperature and humidity sensor is abnormal, the compressor and fan are turned off, the running lights are flickering, and other indicator lights are extinguished. At this time, all keys cannot work. After the sensor failure is eliminated, the key should be re -opened to work normally.

Maintenance Of Machine

Do shutdown the machine and cut power before maintenance.

General maintenance
Wipe the body with soft cloth in daily use. Use a wet hard cloth to wipe dirty body, or use a soft cloth moistened with a little diluted neutral detergent.

Regular maintenance
Filter Cleaning: it will affect the dehumidifying effect or cause malfunction if accumulate dust on filter , it needs to be cleaned regularly, clean it at least once a month. Use dust catcher to remove dust or put filter into clean water (<40 ℃ ) to wash, then place filter back after cleaning.

Attention:
1.The filter cannot be put in sunlight directly or roasted to avoid distortion.
2.The filter must be placed before power up machine.
3.Long time of non-use ，cut the power or unplug power line to put it in dry and shady place.
4.Do not put down the machine to avoid damage and malfunction.
