Important Safe Guards
1） Please be sure your electricity is
correct.
2) To protect against electrical
shock, do not place it in near
window or in bathroom.
3） Please ensure the unit is not
placed closely to the high
temperature appliance, in case of
plastic destroying and fire.
4） Never operate this unit in an
explosive or corrosive
atmosphere.
5） Always guide if children operate.
Never disassemble the unit, and
never try to carry out repairs or
adjust the unit yourself.
6) Operate this unit on a horizontal
surface to avoid vibration and
noise.

7） Do not use the unit when slanted.
If toppled over, please pull out
the plug at once.
8） Ensure there is 30 cm of clear
space on all sides of the unit.
9） Make sure the inlet and outlet
ventilation is not blocked at all
times.
10） Do not spray water on the unit,
spraying water may cause
malfunctioning and electric
shock.
11） Never pull the socket by using
damp hands.
12） Always switch off at the socket
before unplugging to avoid
electric shock or arcing.

13） Switch off and unplug the unit,
empty the water reservoir when
not using the unit for a long time.
14） Do not pull power wire by force
because it will cause damage to
power wire.
15） Never put fingers or other objects
in any openings of the unit.
16） When moving this machine, please
remove the water tank and empty the
water in order to avoid water leakage.

Room Environment For Operating
1. Suitable environment temperature is between 5°C to 35°C
2. Operate the unit indoors, e.g. living room, bedroom, etc. Never use it in wet
environment or outdoors.
3. Make sure the door and window are closed before turning on the unit.
4. Ensure that the unit is placed on a stable and flat floor surface. If the floor
surface is not even there is a risk that the unit may be unstable and topple
over. Also excessive vibration and noise may be result.

2. Operation Of Key Pads:
When plug into power socket,all the LED indicator lamp on control panel and
digit-display lighting 1s then crushing out,the buzzer warning 2 times.
2.1 On/Off: (control turn on/off)
(water tank full switch is on closed condition)
• Pressing On/Off button to start up the machine,the buzzer warning
3times, fan and compressor will start up, high level speed lamp will
light and digit-display tube indicate Room humidity value,
continuing dehumidifying indicator lamp lighting and machine is
going to continuing dehumidifying, stepping motor will turn up
95°(anticlockwise).
• Pressing On/Off button to switch off, the buzzer will warn 3 times,
then it will switch off all the output and indication, stepping motor
will turn down 100°(clockwise), then stop.
2.2 Fan: (Pressing 1st time, machine will operate in low level, pressing
2nd time to operate in high speed; and circularly like this.
 Remark:
  ①If the machine is setted on the low speed level and compressor is operating, when the
Room temperature is ≥32℃ , the fan motor will turn to high-level automatically, the fan
motor’s high-speed level’s indicator’s lamp is lighting and wind speed’s button is
functioning, but the output won’t be changed and the high-speed level indicator lamp will
light and keep it; when Room temperature ≤30℃,machine will turn back original setting
mode automatically.
  ②When the machine is defrosting,fan motor will operate in high speed level all the time, and
corresponding indicator is lighting.
1. On/Off: Switch on/off the power.
2. Fan: Pressing the button to set high or low level
3. Set: Pressing the button to set target Room humidity, you can set: 40%RH, 45%RH, 50%RH,
55%RH, 60%RH, 65%RH, 70%RH, 75%RH, 80%RH and continuing operation.
4. Swing: Pressing the button to set swing.

Remark: The humidity just can be set when humdity setting indicator is lighting.
• Pressing 1st to make the machine from continuing dehumidifying mode to
the 40%RH(target humidity), continuing dehumidifying indicator lamp
crushing out and setting indicator lamp lighting up. When the Room
humidity is lower 1%RH than setted humidity,compressor stop working
and fan operating in low level. Then if the Room humidity is higher
5%RH than set humidity, compressor recover working and fan start
working in high or low speed level.
• Pressing settting button 2nd time to make the machine’s target humidity
from 40%RH turn to 45%RH. When temperature and humidity sensor test
Room humidity ≤1%RH than set humidity(45%RH), the compressor
doesn’t work and fan turn to low-speed level to operate. When product test
Room humidity ≥5%RH,compressor does work and fan operate in high
or low speed level. When the set humidity is in 50%RH, 55%RH, 60%RH,
65%RH, 70%RH, 75%RH, 80%RH, its operation procedure is same with above.

3. Automatic Defrosting:
When machine is working under low-temperature, the evaporator’s surface
will defrost, to guarantee machine’s normal operating, the product has
defrosting-automatically function.
4. Water full protection function:
When machine is operating, if the water tank is full,
the buzzer will warn 10 times, full indicator
lamp will light and machine stop working
at the same time. Please fectch out water tank
and empty water, then put back and it
will work as per the previous model
(dehumidifying function will start after 3 minutes).
Remark:
① When water full switch is cut off and then close,machine will
recover the previous working mode and stepping motor will
turn up(anticlockwise) 95°, if the water full switch is closed
within buzzer warn 10 times, the buzzer will stop warning;
② Water ful switch cut off, the stepping motor will turn down(clockwise) move 100°;
③ Except ON/OFF button,the other button is not useable, and also no buzzer
Operating introduction
P12
• If the temperature sensor test temperature of evaporator’s copper tube ≤-1℃,
compressor will continue working 30 minutes and then it will stop working
(product will defrost), the indicator lamp of fan’s high level and defrosting are
lighting, other indication keep original condition, after temperature sensor test
the temperarure of evaporator’s copper tube ≥2℃ and machine’s defrosting time
must be ≥10 minutes at same time, then compressor can start working and
defrosting indicator lamp going out,the other indication keep original condition.
• Pressing On/Off button to switch off, the buzzer will warn 3 times, then it will
switch off all the output and indication, stepping motor will turn down
100°(clockwise), then stop.

5. Compressor stop/start working function:
When the machine is operating,any operation can cause compressor stop
working.And machine will turn to protection funtion of compressor stop
working 3 minutes and then start up,the other function is normal.
6. Low&High temperature protection function:
When temperature and humdity sensor test Room temperature≤0℃ or ≥40℃
and the sensor’s NTC disconnection or short circuit, compressor and fan motor
haven’t output, buzzer warning all the time and there is no reflection when
pressing any button, and it just will be effective after switch ON anew.
7. Failures Of Humidity&Temperature Sensor:
When the connect wire of humidity and temperature sensor breaks off, the
symbol of continuous dehumidification ”Cont” will wink. It doesn’t work
when pressing humidity setting button, but other function is well.
The appliance comes into continuous dehumidifying mode.
8. Refrigerent leakage test function:
The compressor will test the temperature of temperature and humdity sensor
and NTC of evaporator’s copper tube in every 8 minutes; If compressor test the
temperature different value is ≤3℃ between temperature and humidity sensor
and evaporator’s NTC successive 2 times, then it indicates abnormal, digit tube
blink (lightening 1s and extinguishing 1s)
