1. IMPORTANT SAFETY INFORMATION
To prevent injury to the user or other people and property
damage, the following instructions must be followed. Incorrect
operation due to ignoring of instructions may cause harm or
damage.
Ask your dealer for installation of the air conditioner.
Incomplete installation performed by yourself may result in a
water leakage, electric shock, and fire.
Ask your dealer for improvement, repair, and
maintenance.
Incomplete improvement, repair, and maintenance may result
in a water leakage, electric shock, and fire.
In order to avoid electric shock, fire or injury, or if you
detect any abnormality such as smell of fire, turn off the
power supply and call your dealer for instructions.
Never let the indoor unit or the remote controller get wet.
It may cause an electric shock or a fire.
Never press the button of the remote controller with a
hard, pointed object.
The remote controller may be damaged.
Never replace a fuse with that of wrong rated current or
other wires when a fuse blows out.
Use of wire or copper wire may cause the unit to break down
or cause a fire.
It is not good for your health to expose your body to the
air flow for a long time.
Do not insert fingers, rods or other objects into the air
inlet or outlet.
When the fan is rotating at high speed, it will cause injury.
Never use a flammable spray such as hair spray, lacquer
or paint near the unit.
It may cause a fire.
Never touch the air outlet or the horizontal blades while
the swing flap is in operation.
Fingers may become caught or the unit may break down.
Never put any objects into the air inlet or outlet.
Objects touching the fan at high speed can be dangerous.
Never inspect or service the unit by yourself.
Ask a qualified service person to perform this work.
Do not dispose this product as unsorted municipal
waste. Collection of such waste separately for special
treatment is necessary.
Do not dispose of electrical appliances as unsorted
municipal waste, use separate collection facilities.
Contact you local government for information regarding the
connection systems available.
If electrical appliances are disposed of in landfills or
dumps, hazardous substances can leak into the
groundeater and get into the food chain, damaging your
health and well-being.
To prevent refrigerant leak, contact your dealer.
When the system is installed and runs in a small room, it is
required to keep the concentration of the refrigerant, if by any
chance coming out, below the limit. Otherwise, oxygen in the
room may be affected, resulting in a serious accident.
The refrigerant in the air conditioner is safe and normally
does not leak.
If the refrigerant leaks in the room, contact with a fire of a
burner, a heater or a cooker may result in a harmful gas.
Turn off any combustible heating devices, ventilate the
room, and contact the dealer where you purchased the
unit.
Do not use the air conditioner until a service person confirms
that the portion where the refrigerant leaks is repaired.
Do not use the air conditioner for other purposes.
In order to avoid any quality deterioration, do not use the unit
for cooling precision instruments, food, plants, animals or
works of art.
Before cleaning, be sure to stop the operation, turn the
breaker off or pull out the supply cord.
Otherwise, an electric shock and injury may result.
In order to avoid electric shock or fire, make sure that an
earth leak detector is installed.
Be sure the air conditioner is grounded.
In order to avoid electric shock, make sure that the unit is
grounded and that the earth wire is not connected to gas or
water pipe, lightning conductor or telephone earth wire.
In order to avoid injury, do not remove the fan guard of
the outdoor unit.
WARNING
The safety precautions listed are divided into two categories. In either
case, important safety information is listed which must be read.
CAUTION
Failure to observe a caution may result in injury or damage
to the equipment.
Failure to observe a warning may result in death. The
appliance shall be installed in accordance with national
wiring regulations.

Do not operate the air conditioner with a wet hand.
An electric shock may happen.
Do not touch the heat exchanger fins.
These fins are sharp and could result in cutting injuries.
Do not place items which might be damaged by moisture
under the indoor unit.
Condensation may form if the humidity is above 80%, the
drain outlet is blocked or the filter is polluted.
After a long use, check the unit stand and fitting for
damage.
If damaged, the unit may fall and result in injury.
To avoid oxygen deficiency, ventilate the room
sufficiently if equipment with burner is used together
with the air conditioner.
Arrange the drain hose to ensure smooth drainage.
Incomplete drainage may cause wetting of the building,
furniture etc.
Never touch the internal parts of the controller.
Do not remove the front panel. Some parts inside are
dangerous to touch, and a machine trouble may happen.
Never expose little children, plants or animals directly to
the air flow.
Adverse influence to little children, animals and plants may
result.
Do not allow a child to mount on the outdoor unit or
avoid placing any object on it.
Falling or tumbling may result in injury.
Do not operate the air conditioner when using a room
fumigation - type insecticide.
Failure to observe could cause the chemicals to become
deposited in the unit, which could endanger the health of
those who are hypersensitive to chemicals.
Do not place appliances which produce open fire in
places exposed to the air flow from the unit or under the
indoor unit.
It may cause incomplete combustion or deformation of the
unit due to the heat.
Do not install the air conditioner at any place where
flammable gas may leak out.
If the gas leaks out and stays around the air conditioner, a
fire may break out.
The appliance is not intended for use by young children
or infirm persons without supervision.

for at least 12 hours before using the air conditioner. Besides
that, please be keep in mind that do not cut off the power supply
immediately, for the unit completely shut down needs to spend a
day-night.( In order to prevent the compressor drive-up by
forced, then heating the crankcase.)
Do not block the air inlet and outlet, if that so the performance
would reduce and the unit couldn’t be start for which protect
device is on service.

6. OPERATION PRECAUTIONS
NOTE
The cooling capacity of the air conditioner is measured in a
standard environment where the indoor dry/wet bulb tempera-
ture is 27°C/19°C and the outdoor dry/wet bulb temperature is
35°C/24°C; the heating capacity is measured in a standard
environment where the indoor dry/wet bulb temperature is
20°C/15°C and the outdoor dry/wet bulb temperature is
7°C/6°C; and the actual cooling/heating capacity changes with
the rise/fall of the indoor/outdoor environment temperature and
relative humidity.
The noise of the unit is measured in the semi noise suppression
lab according to the national standards, and the accuracy extent
is ±3dB(A).
During the actual service, the noise will be changed according
by ducts, and the practical noise value is
about 45dB(A) or lower.(after be installed the mute device.)
External static pressure range of the air conditioner under
experiment is 0 Pa.
Read this operation manual carefully before operating the unit.
Grasp the key points in the manual, and seek help from the con
distributor for any question.
This air conditioner is designed to provide a comfortable room
environment, and is applicable to the purposes described in the
manual only.
