1. IMPORTANT SAFETY INFORMATION
To prevent injury to the user or other persons, as well as
property damage, the following instructions must be followed.
Incorrect operation due to ingnorance of instructions may
cause product damage or personal harm.
Consult your dealer for installation of the air conditioner.
Incomplete installation performed by yourself may result in a
water leakage, electric shock, or fire.
Ask your dealer for methods of improvement, repair, and
maintenance.
Improper 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 fire odors, turn off the
power supply and call your dealer for more instructions.
Never let the indoor unit or the remote controller get
wet.
It may cause an electric shock or a fire.
Do not use the air conditioner for abnormal purposes.
In order to avoid any quality degredation, do not use the unit
for cooling of precision instruments, food, plants, animals, or
works of art.
Before cleaning, be sure to cease operation and turn the
breaker off or pull out the supply cord.
Otherwise, an electrical shock and possible injury may result.
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 an incorrectly rated
current, or other wires, when a fuse blows out.
Use of wire or copper fuses 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 prolonged period of time.
Do not insert fingers, rods, or other objects into the air
inlet or outlet.
When the fan is rotating at a high speed, it can cause injury.
Never use a flammable spray, such as hair spray,
lacqueror, 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 within, or the unit may break.
Never put any objects into the air inlet or outlet.
Objects coming into contact with the high speed fan can
become dangerous.
Never inspect or service the unit by yourself.
Ask a qualified service person to perform this work.
Do not dispose of this product as unsorted municipal
waste. Separate collection of such waste for special
treatment is necessary.
Do not dispose of electrical appliances as unsorted
municipal waste. Use separate collection facilities.
Contact your local government for information regarding the
collection systems available.
If electrical appliances are disposed of in landfills or
dumps, hazardous substances can eventually leak into
the groundwater 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 it leaks, below the limit. Otherwise, oxygen in the
room may be affected, resulting in a serious hazard.
The refrigerant in the air conditioner is safe and normally
does not leak.
If the refrigerant leaks inside the room, contact with fire from a
burner, heater, or cooker may result in harmful gas. Turn off
any combustible heating devices, ventilate the room, and
contact the dealer from where you purchased the unit. Do not
use the air conditioner until a service person confirms that the
segment from where the refrigerant leaks is repaired.

8. THE FOLLOWING SYMPTOMS ARE NOT
AIR CONDITIONER TROUBLES:
Symptom 1: System does not operate
Symptom 2: System switches to Fan
Mode during Cooling Mode
Symptom 3: White mist comes out of the Unit
Symptom 4: Noise of Air Conditioners cooling
The air conditioner fails to start immediately after the ON/OFF
button on the remote controller is pressed. If the operation lamp
lights up, then the system is in normal condition. To prevent
overloading of the compressor motor, the air conditioner starts 3
minutes after it is turned ON.
If the operation lamp and the "
PRE-DEF” indicator (cooling and
heating type) or “Fan-Only” indicator (cooling-only type)
lights
up, it means that you chose heating mode. When just booting, if
the compressor has not started, the indoor unit appears as
"anti cold wind" protection, due to overflow outlet temperature.
In order to prevent indoor evaporator frosting, the system will
switch to fan mode automatically, and will restore back to
cooling mode shortly after.
When the room temperature drops to the set temperature, the
compressor goes off, and the indoor unit changes to fan mode.
When the temperature rises up, the compressor starts again. It
works the same way in heating mode.
Symptom 3.1: Indoor Unit
Symptom 3.2: Indoor Unit, Outdoor Unit
Symptom 4.1: Indoor Unit
When humidity is high during a cooling operation, and if the
interior of an indoor unit is extremely dirtied, the temperature
distribution inside a room becomes uneven. It is necessary to
clean the interior of the indoor unit. Ask your dealer for details
on cleaning the unit. This operation requires qualified service
personnel.
When the system is switched over to a heating operation after a
defrosting operation, any moisture generated by defrosting
becomes steam, and is emitted outward.
A continuous and low hissing sound is heard when the system
is in a cooling operation, or at a stop.
When the drain pump (optional accessory) is in operation, this
noise is also heard.
A "pss-pss" squeaking sound is heard when the system stops
after completion of a heating operation.
Expansion and contraction of plastic parts caused by
temperature changes also make this noise.
Symptom 4.2: Indoor Unit, Outdoor Unit
A continuous low hissing noise is heard when the system is in
operation.
This is the sound of refrigerant gas flowing through both the
indoor and outdoor units.
A hissing sound is heard at the start, or immediately after,
stopping operation, or beginning a defrosting operation.
This is the noise of refrigerant, caused by flow stoppage or flow
change.
Symptom 4.3: Outdoor Unit
When the tone of operating noise changes.
This noise is caused by a change of frequency.
Symptom 5: Dust comes out of the Unit
Symptom 6: The Unit gives off strange odors
When the unit is used for the first time in a long time.
This is most likely due to dust having gotten inside the unit.
The unit can absorb the smell of rooms, furniture, cigarettes,
etc., and then emit it again.
Symptom 7: The Outdoor Unit fan does not
spin.
During operation, the speed of the fan is controlled in order to
optimize product operation.
The operation lamp is flashing rapidly (~5Hz) and the lamp
continues flashing rapidly after turning off the power and turning
it on again. (Refer to Table 9-1)
Remote controller starts malfunctioingn or the buttons do not
work well.
A safety device, such as a fuse or breaker, frequently actuates.
Obstacles and/or water enter the unit.
Water leaks out of the indoor unit.
Any other strange, concerning malfunctions.
9. TROUBLESHOOTING
If one of the following malfunctions occur, cease operation,
shut off the power, and contact your dealer.
If the system does not properly operate, except when the above
mentioned cases or the above mentioned malfunctions is
evident, investigate the system according to the following
procedures (Refer to Table 9-2).
