Ⅰ
. Important safety instructions
Please read all the instructions carefully before using the
machine
Do make sure the power supply is 380V/50Hz before
power up the machine
Don’t power on/off the machine by connecting/cutting the
power supply
Don’t roll or damage the power cord when install or remove
the machine
Don’t put finger or any other rodlike object into the machine
Do cut off the power cord before cleaning or maintain the
machine
Don’t use in arrow and sealed space, make sure to connect
the ground lead.
Don’t do any change of machine unless guiding by our
technicians
Attention: The machine hasloss and dislocation phase
protector,when the connected three phases outer power supply is not
correct as the machine setting , the protector will be disconnected, all
the indicator on control panel will be regularly display, but the machine
will not run. Please correct the power supply phase connection, and
restart the machine at this condition. This operation requires
professional electric technicians.

Ⅱ. 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.

-Key Function -
1. “Power”On/Off : press the key into open and close mode
2. “Time” Press the key into timed on/off setting mode.
3. “+”Press the key to set the humidity value up with 1%RH
scale in running mode. Press the key to set the hours up with 1
hour scale in timed on/off setting mode.
4. “-”Press the key to set the humidity value down with 1%RH
scale in running mode.Press the key to set the hours down with 1
hour scale in timed on/off setting mode.

5. “Humidity display”Current ambient humidity display when in
standby mode and running mode. Blinking when at humidity
setting mode.
6. “Running indicator light”Blinking when the machine running.
7. “Defrosting indicator light”
Blinking when the machine is automatic defrosting
8. “Timed on/off hours display”
Blinking when in timed on/off setting mode
9. “Ambient temperature display”
10. “Dehumidifying”
Light on when in standby mode and running mode
Blinking when in the 3 minutes delay protection mode
Ⅴ. Protection function
1、Automatic defrost protection function
The dehumidifier will defrost automatically when it frost on a
certain level on the evaporator, compressor shutdown. The
dehumidifier will start automatically when defrosting finished. We
set the machine defrost when ambient temperature is under 18℃.

2、Compressor delay start protection function
If you want to start the machine in 3 minutes after shutdown
dehumidifier, the compressor will start after 3 minutes for delay
protection.
Ⅵ. Caution in use
1、Do not tilte the machine more than 45 ° in moving or installation
to avoid damage to the compressor.
2、The working temperature scope of the machine is 5℃
~ 38 ℃.
3. The room temperature will go up 3℃from compressor heat
dissipation when dehumidifier running, it’s normal phenomenon,
please feel free to use.
4. It’s not necessary to use dehumidifier when the room
temperature is below 10℃, the absolute humidity is quite low at
this condition.
5. The air inlet and outlet must be at least 50cm away from the wall
spacing, so as not to affect the dehumidifying effect or cause a
malfunction.
6. Please try to sealenvironmentbetter to increase the effect of
dehumidifying

7. Do not place the machine in the area which may come into
contact with water or chemical.
8. Do not use any relay, extension line or adapter to connect the
power of machine.
9. Do not place the machine next to the stove, heater and other
equipment will dissipate heat, and area with direct sunlight or
wind and rain.
10. Do place the plug stably and clean the dust on power line.
11. Do not damage or modify the power line, do not repair by
yourself and disassemble or modify the machine.
12. Do place the drainage tube smoothly for continuously drain.
13. Please shutdown the machine and cut power when in
malfunction.
