Starting Operation ( 4 )
Press "On/Off" button, and when the unit receives the signal, it gives out two "beep" tones,
the operation light is on and the dehumidifier starts operation.
NOTE:
If it is desired to run the machine at the same settings for mode, air flow and temperature as the last operation
skip Steps 1~3 and start the machine directly. If the interval is shorter than 3 minutes from last shut down to
the present switch-on, the compressor only re-starts after 3 minutes to protect the system. After switching on
and if the mode is changed, the system may delay for 3 minutes before starting operation.
When heating mode is selected, the internal fan will delay operation for a while when the machine is switched
on to prevent cool air circulation at the beginning. After switching on, air flow amount and temperature may be
separately adjusted as desired.

NOTE:
To stop the up-down air louver in a desired position, set the louver to automatic swinging and when it reaches
the desired position, stop the louver from swinging. It is necessary to adjust the louver angle by means of the
remote controller, Setting of the louver with the hand may affect its normal operation, in which event, switch
off the unit temporarily and re-start operation.
To get the best effect, the up-down air flow is usually set in the following manner : Dehumidifying - Horizontal
air direction or upward air direction. Heating -Downward air direction
Changing Left-Right Air Direction
NOTE: Don’t move the Left-Right van directly.

Timer Operations
Timer Switch On
1. Press "Timer On" button to set time for timer-on switching.
Press the button once to change the time interval of 1 hour in
a cyclic manner of 6, 7, 8 ...12 ..1, 2..5, 6 (The display is
showing the previous time as the starting time of the present
setting). If the button is held down, the time interval will
increase progressively by 1 hour unit.
2. Point the remote controller towards the receiver on the unit,
Press "Timer Confirm" button to send the timer setting to the
dehumidifier. Then the timer light on the unit lights up,
indicating that the unit is in the timer mode. When it reaches
the switch-on time, the dehumidifier will operate in the pre-set
modes.
NOTE:
Before timer operation, please set the operation mode,
temperature, air flow etc. on the remote controller, With timer being
set to switch-on mode. the Dehumidifier will operate according to
the last setting.
Usually, timer-on setting is made while the dehumidifier is not
in operation. If timer-on is set while the dehumidifier is running,
then the unit will shut down immediately and re-start at the pre-set
time.
If the "On-Off" button is pressed while the unit is under timer-on
setting, then the unit will start immediately, the timer setting is cancelled and the timer light will be off.
Timer Switch Off
1. Press "Timer Off" button to set time for timer-off switching. Press the button once to change the time interval
of 1 hour in a cyclic manner of 6, 7, 8 ...12 ..1, 2..5, 6 (The display is showing the
previous time as the starting time of the present setting). If the button is held down, the time interval will
increase progressively by 1 hour unit.
2. Press "Timer Confirm" button to send the timer setting to the Dehumidifier. Then the timer light on the unit
lights up, indicating that the unit is in the timer mode. When it reaches the switch-off time, the air-conditioner
will automatically shut down.
NOTE:
Timer-Off can only be set when the Dehumidifier is running.
Timer-On and Timer-Off cannot be set at the same time.
Timer display on the remote controller : While time passes, the display shows the remaining time.
If the "On-Off" button is pressed while the unit is under timer-off setting, then the unit will shut down
immediately, the timer setting is cancelled and the timer light will be off.

Defrost system
Sequences of the defrosting:
1. Start
The defrosting is engaged if the following conditions are at the same time fulfilled:
- the compressor and the fan motor run without stopping;
- the defrosting sensor temperature lower than 3 , and the duration of time more than 45 minutes;
- the defrosting sensor temperature goes down to -7 .
2. After 15 seconds, the 4 way valve shifts.
3. Five seconds after its stop, the compressor starts alone ; And the accumulated freeze on the gills becomes
melting, what is generally with a steam cloud .
4. Stop:
The defrosting stops if one of the following conditions is fulfilled:
- the defrosting operates 20 seconds and the detected temperature by the defrost sensor goes up to 12 ;
- the compressor had run totally 8 minutes.
5. The compressor runs.
6. After 15 seconds the 4 way valve shifts
7. Five seconds after its stop the compressor and the fan start for restarting in heating mode.
8. The running light is blinking during defrosting.
Water drainage system
During the dehumidify mode, the condenser water will be drained into the internal water tank .When the water
reaches the certain level, the water drain pump will work. If the water can be drained out in 8 minutes, the
dehumidifier will keep working. If not, the compressor and the motor will stop working. Mean while an error
message “ E4 “ will appear in the control panel to inform you to empty the water.
In this instance, you should cut the power off, and then restart the dehumidifier ,and the operation
will continue .
Error Codes
E1 : Room temperature sensor error;
E2 : Defrost temperature sensor error;
E3 : Humidity sensor error;
E4 : Drain error;
P1 : Electrical heater error;

WARNING
!
Before maintenance, be sure to turn off the system and the circuit breaker.
Remote Controller Body
Do not use water, wipe the
controller with a dry cloth.
Do not use glass cleaner or
chemical cloth.
Wipe the air conditioner by
using a soft and dry cloth.
For serious stains, use a neutral
detergent diluted with water.
Wring the water out of the cloth
before wiping. then wipe off the
detergent completely.
Do not use the following for cleaning
Gasoline, benzine, thinner or cleanser Hot water over 40 (104 )
may damage the coating of the unit. may cause discoloring or deformation.
Air Filter cleaning
Press the clasp on the top of the grill and pull the grill out, and then
the filter will be taken out along a gradient way.
Clean the filter.
Use a vacuum cleaner to remove dust, or wash the filter with water.
After washing, dry the filter completely in the shade. Then, reinstall
it onto the unit.
To keep your Dehumidifier in good condition after season:
1. Operate in FAN mode for about half a day.
On a fine day, unit shall be started and operate in FAN
mode for about half a day until the inside of the unit
becomes thoroughly dry.
2. Turn off the power supply main switch.
3. Cleaning the body. 4. Take out the batteries from the wireless remote

Trouble shooting
Before asking for service, check the following first.
The system does not
restart immediately.
l When unit is stopped, it won' t restart immediately until 3
minutes have elapsed to protect the system.
When the electric plug is pulled out and reinserted, the
protection circuit will work for 3 minutes to protect the
dehumidifier.
Noise is heard:During unit operation or at stop, a swishing or gurgling
noise may be heard. At first 2-3 minutes after unit start,
this noise is more noticeable. (This noise is generated by
refrigerant flowing in the system.)
During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or
shrinking because of temperature changes.
Should there be a big noise from air flow in unit operation,
air filter may be too dirty.
Smells are generated.This is because the system circulates smells from the
interior air such as the smell of furniture, cigarettes.
Does not work at all.
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
