TROUBLESHOOTING
I Normal Operation
Is it okay?
I Call the Dealer Immediately
If the following conditions occur, turn off and unplug the
main power supply, and then call the dealer immediately.
This is the answer
•
Air conditioner has been restarted, but does not
operate for 3 minutes.
•
•
•
•
•
•
This is to protect the air conditioner. Wait until the air
conditioner begins to operate.
•
•
Abnormal noise is heard during operation.
This is the sound of refrigerant flowing inside the air
conditioner.
•
•
•
•
•
A sound like water flowing can be heard.
Water or foreign material gets into the remote
control by mistake.
Condensation occurs when the airflow from the air
conditioner cools the room.
It seems that fog is coming out from the air
conditioner.
•
•
•
•
Water leak from the indoor unit.
This may be a damp smell emitted by the wall,
carpet, furniture or clothing in the room.
The room has a peculiar odour.
Switches or buttons do not operate properly.
The circuit breaker switches off frequently.
This is to remove smell emitted by the surroundings.
During Automatic Vertical Airflow setting,
indoor fan stops occasionally.
Power supply cord and plug become unusually
warm.
In COOL/DRY operation, moisture in the air
condenses into water on the cool surface of outdoor
unit piping that causes dripping.
The outdoor unit emits water or steam.
•
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).
•
(For Heat Pump Model only)
Operation stops for about 12 minutes during
heating (The power indicator blinks).
(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.
•
(For Heat Pump Model only)
During heating operation, indoor fan may
run at on and off conditions.
I Abnormal Operation
Is it okay?
The air conditioner does not operate.
Please check
•
•
•
•
Has the circuit breaker been tripped?
Has the power plug been removed from the wall outlet?
Is the timer being used correctly?
•
•
Air conditioner produces loud noise during
operation.
•
•
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?
The air conditioner does not cool or warm
effectively.
•
Are all windows and doors closed?
•
Remote control / display doesn’t work
•
•
Batteries empty?

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 these important contents are related to safety. The meaning of each
indication used is as below. Incorrect installation due to ignoring of the instruction will cause harm or damage, and the
seriousness is classified by the 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 denotes item that is PROHIBITED 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. Wire routing 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. When carrying out piping connection, take care not to 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, cause abnormally high pressure in the refrigeration cycle, and
possibly result in explosion and injury. (Only for models: CS/CU-V7CK, V9CK, V12CK, W7CK, W9CK, W12CK)
10. • When connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same may cause
abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and 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 (Only for models: CS/CU-V7CK, V9CK,
V12CK, W7CK, W9CK, W12CK).
11. Do not modify the length of the power supply cord or use of the extension cord, and do not share the single outlet with
other electrical appliances. Otherwise, it will cause fire or electrical shock.
