							TROUBLESHOOTING
■Normal Operation
Is it okay?
• Air conditioner has been restarted, but does not
operate for 3 minutes.
• A sound like water flowing can be heard.
• It seems that fog is coming out from the air
conditioner.
• The room has a peculiar odour.
• During Automatic Vertical Airflow setting,
indoor fan stops occasionally.
• The outdoor unit emits water or steam.
• (For Heat Pump Model only)
Operation stops for about 12 minutes during
heating (The power indicator blinks).
• (For Heat Pump Model only)
During heating operation, indoor fan may
run at on and off conditions.
■Abnormal Operation
Is it okay?
• The air conditioner does not operate.
• Air conditioner produces loud noise during
operation.
• The air conditioner does not cool or warm
effectively.This is the answer
• This is to protect the air conditioner. Wait until the air
conditioner begins to operate.
• This is the sound of refrigerant flowing inside the air
conditioner.
• Condensation occurs when the airflow from the air
conditioner cools the room.
• This may be a damp smell emitted by the wall,
carpet, furniture or clothing in the room.
• This is to remove smell emitted by the surroundings.
• In COOL/DRY operation, moisture in the air
condenses into water on the cool surface of outdoor
unit piping that causes dripping.
• This is to melt the frost which has accumulated on
the outdoor unit (defrosting operating). This will take
no longer than about 12 minutes. Water drips from
the outdoor unit. Wait until this operation ends. (the
power indicator will light up).
(Frost will accumulates on the outdoor unit when the
outdoor temperature is low and humidity is high.)
• This is to prevent undesired cooling effect during
heating operation.
Please check
• Has the circuit breaker been tripped?
• Has the power plug been removed from the wall
outlet?
• Is the timer being used correctly?
• Is the installation work slanted?
• Is the front grille closed properly?
• Has the temperature been set incorrectly?
• Are the filters dirty?
• Are the intake or outlet vents of the outdoor unit
obstructed?
• Are all windows and doors closed?
■Call the Dealer Immediately
If the following conditions occur, turn off and unplug the
main power supply, and then call the dealer immediately.
• Abnormal noise is heard during operation.
• Water or foreign material gets into the remote
control by mistake.
• Water leak from the indoor unit.
• Switches or buttons do not operate properly.
• The circuit breaker switches off frequently.
• Power supply cord and plug become unusually
warm.

10.1. Safety Precautions
 • Read the following “SAFETY PRECAUTIONS” carefully before installation.
 • Electrical work must be installed by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit
for the model to be installed.
 • The caution items stated here must be followed because theseimportant contents are related tosafety. The meaningof each
indication used is as below. Incorrect installation due to ignoring of the instruction will cause harm or damage, and the
seriousness is classified bythe following indications.
This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to properties only.
The items to be followed are classified by the symbols:
Symbol with background white denotesitem that is PROHBITED from doing.
 • Carry out test running to confirm that no abnormality occurs after the installation. Then, explain to user the operation, care and
maintenance as stated in instructions. Please remind the customer to keep the operating instructions for future reference.
1.Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or fire.
2.Install according to this installation instruction strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
3.Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, fire or
electrical shock.
4.Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not properly
done, the set will drop and cause injury.
5.For electrical work, follow the local national wiring standard, regulation and this installation instruction. An independent circuit and single
outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.
6.Use the specified cable (1.5 mm2) and connect tightly for indoor/outdoor connection. Connect tightly and clamp the cable so that no
external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.
7.Wirerouting must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will
cause heat-up at connection point of terminal, fire or electrical shock.
8.Whencarrying out piping connection, take care notto let air substances other than the specified refrigerant go into refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.
9.When connecting the piping, do not allow air or any substances other than the specified refrigerant (R410A) to enter the
refrigeration cycle. Otherwise, this may lower the capacity, causeabnormally high pressure inthe refrigeration cycle, and
possibly result in explosion and injury.
10. • W hen connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same may cause
abnormally high pressure inthe refrigeration cycle (piping), and possiblyresult in explosionand injury. Use only
R410A materials.
 • Thickness of copper pipes used with R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8
mm.
 • It is desirable that the amount of residual oil is less than 40 mg/10 m.
11.Do not modify the length of thepower supply cord oruse of the extension cord, and do not share the single outlet with
other electrical applian ces. Otherwise, it will cause fire or electrical shock.

							1.The equipment must be earthed. It may cause electrical shock if grounding is not perfect.
2.Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at
surrounding of the unit, it may cause fire.
3.Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the
furniture.
1.Selection of the installation location.
Select a installation location which is rigid and strong enough to support or hold the unit, and select alocation for easy maintenance.
2.Power supply connectionto the room air conditioner.
Connect the power supply cordof the room air conditioner to the mains using one of the following method.
Power supply point shall be theplace where there is ease for access for the power disconnection in case of emergency.
In some countries, permanent connection of this roomair conditioner to thepower supply is prohibited.
 1. Power supply connection to the receptacle using a power plug.
Use an approved 15A/16A power plug with earth pin for the connection to the socket.
 2. Power supply connection to a circuit breaker for the permanent connection. Use an approved 16A circuit breaker for the permanent
connection. It must be a double pole switch with a minimum 3 mm contact gap.
3.Do not release refrigerant.
Do not release refrigerant during piping work for installation, reinstallation and during repairing a refrigeration parts. Take care of the
liquid refrigerant, it may cause frostbite.
4.Installation work.
It may need two people to carry out the installation work.
5.Do not install this applian ce in a laundry room or other location where water may drip from the ceiling, etc.

OUTDOOR UNIT
 • If an awning is built over the unit to prevent direct
sunlight or rain, be careful that heat radiation from the
condenser is not obstructed.
 • There should not be any animal or plant which could be
affected by hot air discharged.
 • Keep the spaces indicated by arrows from wall, ceiling,
fence or other obstacles.
 • Do not place any obstacles which may cause a short
circuit of the discharged air.
