Operating Condition
Power requirement
DRY mode operation
Water pipe
Rated voltage :230V~
The electric components could get damaged if the voltage is too high.
If the voltage is too low, the compressor will vibrate violently
damaging
the refrigerant system and easily causing the compressor
and electrical
components to stop working.
The ground must be connected.
Special socket must be used. Furthermore, the socket and wiring
must conform to the local wiring regulations. And the earthing
must be reliable.
In fixed circuit, there must be electricity leakage protection switch
of enough power capacity and air switch with enough space.
Earth wire To ensure the reliable earthing, please do not connect earth wire to the following places:
Please operate air conditioner in the correct conditions as following.
COOL mode operation
In this mode, the air conditioner operates
efficiently when the ambient temperature
is between 18 and 43 oC.
Humidity inside the room has to be below
90 oC or else the air conditioner condensates
and there could be excessive water running
through the drains of the unit.
In this mode, the air conditioner operates
efficiently when the ambient temperature
is between 18 and 43 oC.

Installation procedure:
1) Remove the sticker from the front panel.
2) Put the unit into the installation hole.
When installing the unit, it should be slanted
down to the back to avoid the enlargement of
noise or vibration. (Slant between 6-10mm.)
(As shown in the illustration.)
The installation place should be strong enough
to avoid any vibrational noises.
3) Fill up gaps in the cabinet with sponge or foam.
Installation assistance:
Use iron support
The installation hole should be strong enough to
support the air conditioner. If it cannot, iron sup-
port has to be used outdoors.
Iron support should be fixed on the building (Shown
at right figure.)
Use sunshade board
To avoid any accidental damage to the unit from
things falling from above, it is recommended to
install a sunshade board and this can be installed
by the installer.
To get the maximum cooling efficiency, the air conditioner is designed to splash the condensation
water on the condenser coil.To the cooling only unit,If the splashing sound annoys you, you can
provide an outside drain by using the following procedure, which may however cause a small loss
of performance.
1. Slide out the chassis from the cabinet.
2. Remove the rubber plug from the body base plate.
3. Install the drain pan to the corner of the cabinet with 2 screws.
4. Connect the drain hose to the outlet on the drain pan bottom.

Operation Tips
Operation for comfort and economy
Do not overcool the room.
This is not good for health and
wastes electricity.
Keep blind or curtains closed.
Do not let sunshine enter the
room directly when the air con-
ditioning is on operation.
Keep the room temp. uniform.
Adjust the vertical and horizon-
tal airflow direction to ensure a
uniform temperature is maintained
in the room. Air can’t be discharged
to the direction of air-in.
Make sure that the doors and win-
dows are tightly closed. Avoid open-
ing doors and windows as much as
possible to maintain indoor
temperatures.
Clean the air filter regularly .
Blockages in the air filter re-
duces dehumidifying effects.
Clean the air filter at least once
every two weeks.
Ventilate the room occasionally.
Since windows are kept closed, it
is a good idea to open them and
ventilate the room now and then.
When starting the unit, curtains or
windows should be closed to pre-
vent the heat/cool leakage.

Caution
Operations for safety and health
1) The plug must be accessible after the appliance is positioned.
2) Do not use this appliance in the laundry.
3) If the power cord is damaged, it must be replaced.
Do not pull out the power cord.

Are air filters dirty?
Is indoor fan speed set at LOW?
Maybe the room is too hot/cool when the unit is
started.
At COOL mode operation, sometimes there is foggy
air flowing out of indoor unit, this is because the room
humid air has been cooling rapidly.
The unit is normal while the indoor outlet is sending
out some odor, because the inlet air may be mixed
with the smell of furniture and smoke.
For a noise that sounds like water flowing:
This is the sound of freon flowing inside the air con-
ditioner unit.
For a noise that sounds like a shower:
This is the sound of the dehumidifying water being
processed inside the air conditioner unit. If there
