Cooling in summer
In hot summer, Air conditioner can cool down
the room air by transferring heat out.
Without reducing the room temp., air conditioner
can dehumidify and make the room air dry and
comfortable.

Operating Condition
Please operate air conditioner in the correct conditions as following.
Power requirement
COOL mode operation
DRY mode operation
Outdoor temperature should be in range of 18 to 43 ,
otherwise it is possible for air conditioner to breakdown.
Outdoor temperature should be in range of 18
to 43 , otherwise it is possible for air conditioner
to breakdown.
Room humidity should be lower than 90%.
Otherwise, it is possible for air conditioner to dew
at air conditioner surface and even drop water af-
ter running for so much time. But this is normal.
Water pipe
Rated voltage and voltage range: 230V 10%
The electric components will be damaged when the voltage is too high.
If the voltage is too low, the compressor will vibrate violently to dam-
age the refrigerant system and easily cause the compressor and elec-
tric components not work.
The ground must be connected.
Special socket must be used. Furthermore, the socket and wiring
must conform to the wiring regulations. And the earthing method
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:

The distance of obstructions from window unit
inside should be upper 300mm, lower 1500mm,
left 500mm,right 500mm, front1500mm.

Installation
Installation precaution:
Window type conditioner is so valuable and the improper installa-
tion of it will cause a lot of damage! Please associate the profes-
sional technician to install the unit and don’t install it by yourself.
Otherwise, we are not responsible for the damage like this.
Location:
The condensation water must be drained away conveniently.
Install air conditioner unit far away from TV set or radio
etc. to avoid disturbing video or voice.
In salt and coastal area or place where is near thermal springs
and polluted by sulphurous gas, or other special areas, please
contact the seller before use.
Avoid a place where is possible for inflammable gas to leak out.
Avoid other heat sources or direct sun light.
Avoid a place where is easy for children to touch.
For window type air conditioner with remote
control, install in a location where is strong elec-
tromagnetic disturbance, you should contact the
seller in advance to avoid the malfunction in use.
How to install:
Choose a location where there are no any obstacle surrounding
the unit, and the plug is accessible.
Prepare the installation hole slightly bigger than unit size.
Choose the installation space according to the following diagram.
Don't use the unit in the immediate surrondings of
a laundry,a bath,a shower or a swimming pool.

Drain water:
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 follo
-wing procedure, whichmay 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.
5. Slide the chassis into its original place in the cabinet.
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.)
(Shown at right figure.)
The installation place should be strong enough
to avoid the enlargement of noise or vibration.
3) Fill up sews 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
Air conditioner should avoid anything to be dropped
into it and avoid direct sunshine. If there is no cover
on it, you should contact the seller for installing
the sunshade board. When installing the sunshade
board, don’t let it block the air inlet at the side grille.

contact the seller firstly.
Then it must be done under the direction of the professional
technician. In addition, the charge of this must be paid.
Noise
Electric wiring
Install in a location where is firm enough to avoid the enlargement of noise
and vibration.
Don’t put anything in front of the outlet of outdoor unit to avoid increasing
noise.
Be sure that hot air ornoise will not inconvenience neighbors.
Please contact the seller as soon as there is strange noise during operation.
Please use the safety support.
Must connect with ground reliably.
The exclusive circuit must be used. But removable socket can’t be used because poor
contact of it can cause over heat or fire.
If the supply cord is damaged,it must be replaced by the manufacturer or your dealer
In fixed circuit, there must be electricity leakage protection switch and leakage current
is less than 30mA.
Air switch (thermal-magnetic breaker) should be installed in the circuit.
Note:
Drain pan and drain hose must be installed before using reverse cycle models.
Drain hose or tubing can be purchased locally to satisfy your particular needs.
Don’t pull the power cord strongly.
or a qualified person to avoid a hazard.
All The dectrical work must be done according to the local wiring regulations.
An all-pole disconnection switch having a contact separation of at least 3mm in all poles
should be connected in fixed wiring
Connecting method between air conditioners and power cord and interconnecting method
of each individual element with one another should accord with wiring diagram on the unit.
The air conditioner should be installed in accordance with national wiring regulation.
