Principle of dehumidifier
The dehumidifier use the refrigeration circuit to change the damp air warm dry air.
When the damp air passes the condenser, the air water will be condensed and the air
will become dry.

Operation Guide
Press "Mode" button to select the required working mode, which is
changed in the following sequence when pressed once:
Heating mode is available only on cooling-heating type air conditioner.
Automatic operation will be explained in detail on next page.
When Automatic FAN is selected, the air-conditioner will automatically select the suit-
able amount of air flow according to room temperature.
When Dehumidifying is selected, the amount of air flow is set by the machine and fan
setting is not functional.
o o
Range of adjustable temperature settings : 16 C ~ 31 C.
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.
Press "FAN" button to select the required amount of air flow,
which is changed in the following sequence when pressed once :
Press "Temperature Adjustment Button " to set temperature 1
degree higher.
Press "Temperature Adjustment Button " to set temperature 1
degree lower.
Hold down the Button to increase of decrease the temperature
settings progressively.
Press "On/Off" button, and when the unit receives the signal, it gives

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.
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.

Defrost system
Sequences of the defrosting:
1- Start
The defrosting is engaged if the following conditions are at the same time fulfiled:
- the compressor and the fan motor run without stopping;
- the defrosting sensor temperature lower than 3 , and the duration of time more
oC
than 45 minutes;
- the defrosting sensor temperature goes down to -7 .
oC
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 fulfiled:
- the defrosting operates 20 seconds and the detected temperature by the defrost
sensor goes up to 12 ;
oC
- 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 mins,
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 .

Do not use the following for cleaning
Gasoline,benzine, thinner or cleanser may
damage the coating of the unit.Hot water over 40
o o
C (104 C ) may cause
discoloring or deformation.
Body
Before maintenance,be sure to turn off the system and the circuit breaker.
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.
Maintenance
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

Trouble shooting
Before asking for service, check the following first.
Is the air filter dirty? Normally it should be
cleaned every 15 days.
Are there any obstacles before inlet and outlet?
Is temperature set correctly?
Are there some doors or windows left open?
Cause or check points
Phenomenon
The system does not restart
immediately.
Noise is heard:
Smells are generated.
Does not work at all.
Multiple
check
Normal
Performance
inspection
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.
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.
This is because the system circulates smells
from the interior air such as the smell of
furniture, cigarettes.
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
