Long press this button for four times, it exit the setting mode.
3
Press this button directly to increase the set humidity. Buzzer buzzes
once for each pressing and the set humidity increases by 1% RH.
Press this button to increase the presetting time, each pressing and
the time il by 1 hour
4
Press this button directly to decrease the set humidity. Buzzer
buzzes
once for each pressing and the set humidity decreases by
1%RH.
Press this button to decrease the presetting time, each pressing and
the time d by 1 hour.
1. Display range for humidity is 5 % -98 %.
2. Auto detection of temperature/humidity failure.
a. When the system detects that temperature sensor exceeds the limited range,
the system enters mode of temperature sensor failure. Under this mode, LCD displays
temperature failure code “E1”, the system works in circle of dehumidification for 30
minutes and defrosting for 10 minutes;
b. When the system detects that humidity sensor exceeds the limited range, the
system enters mode of humidity sensor failure. Under this mode, LCD displays
humidity failure code “E2” and stop working
c. After temperature/humidity sensor failure is eliminated, the system works

hours decrease to be 0, then it shutdown automatically.
d. After setting the mode of preset time, if the dehumidifier is shut off, it will
operate the whole mode of preset time; if it is in operation, it will operate the mode of
“preset stop time'". The setting hours range is 0-24hours.
e. Press "Time’" button for 10s, it display ‘F1", it‘s humidity correction; Press
“Time” button for successively twice, it displays "F2”, it’s defrost interval time (default:
30 minutes). Press “Time” button for successively three times. Is displays “F3”. it’s
defrost time (default: 8 minutes); Press ‘Time” button for successively four times, is
displays “F4”, it can choose the defrost mode, when displays "1
F4”. it enters intelligent
defrosting mode, suitable for ambient temperature is above 10oC; when displays "2
F4”, it enters fixed defrosting mode, suitable for ambient temperature is below 10oC.
VI.Notices
1. If the set humidity is higher than the actual humidity, the dehumidifier stops
working;
2. During dehumidification, after the compressor starts working, the fan and
compressor can only be stopped after working for at least 3 minutes; the compressor
can only be re-started 3 minutes after it stops;
3. If works under low temperature, the dehumidifier may judge the system
temperature automatically and defrost automatically; when defrosting, the indicator
of
defrosting is light, the fan works and compressor stops working.
4. The system has auto memory. When all the mode setting has been finished, if
there is sudden power cut during operation or the power jack slips out, the system may
store the current status before the power is cut and enter the operation mode before
power cut automatically after power is supplied;

If the machine is spared for a long time, please unload the power cord.
When clearing the machine, stop it first and unload the power cord.
Otherwise, human injury may be caused.
During continuous drainage, please place the drain pipe appropriately for smooth
drainage.
If there is any possibility that temperature around pipe may result in icing,
continuous water drain is not allowed.
Do not repair, disassemble or alternate the machine without authorization so as
to avoid fire or electric shock accidents;
Please place the machine in firm places;
If the machine falls down, the water in water tank may leak out and damages stuff
around and results in creepage and cause fire or electric shock accidents;
Knacks to extend the service life of air purification filter mesh: .
If to be spared for a long time, keep the air purification filter mesh in plastic bag
and save hermetically.
Do not use dehumidifier in places that may be exposed to water.
There may be creepage if there is water and result in fire or electric shock.

X. Operation Notices
1. When moving the machine. do not incline the machine for over 45° to avoid
damaging the compressor.
2. Temperature for operation of this machine is 5-38oC
3. When it is operating, the compressor gives off heat when it works, and
ambient temperature may raise by 1-3oC . Such phenomenon is normal and is safe to
use. When ambient temperature is below 10°C and absolute humidity is relatively
low, there is no need to use dehumidifier.
4.The air inlet and outlet must be away from the wall for at least 10 cm in order
not to impair the dehumidification effect.
5. Working environment shall be as airproof as possible to maximize
dehumidification effect.
6. Dust on the air purification filter mesh may impair its effect or even cause
failure. Please clear regularly for at least once a month. If there is much dust in the
environment, it must be cleared once a week or once a day. Pull does the front panel,
clear the filter mesh. Tap the filter mesh slightly or eliminate the dust by vacuum
cleaner or place the mesh in warm water (<40oC and add
appropriate neutral scour)
and brush and then wash with clear water and dry it.
Direct sunlight or baking shall be avoided to prevent deformation.
XI. Instruction on Code Failure
This dehumidifier is able to automatically judge failure. If there is any lailure,
there will be failure code displayed on the humidity display window.
