Safety Precautions
■Read the following warnings and cautions
carefully before operating the system and
use it correctly.
■This manual classifies the precautions to the
user into two categories on the right.
Be sure to follow all as they are all important
to ensure safety.
■After reading this manual, keep it in a place
easily accessible to the user for future
reference.
WARNING
●Do not expose your body to the cool air for a long time, do not cool the room too much.
It will affect your physical conditions and cause health problems.
●Do not put a finger, a rod or other objects into the air outlet or inlet.
As the fan is rotating at a high speed, it will cause injury.
●Do not attempt to repair, relocate, modify or reinstall the air conditioner by yourself.
Incorrect work will cause electric shocks, fire etc. For repairs and reinstallation, consult the dealer
where you bought the air conditioner.
●
If anything abnormal such as a burning smell occurs, stop the operation immediately and turn the breaker OFF.
Continued abnormal operation will cause troubles, electric shocks, fire etc. If anything is
abnormal, consult the dealer where you bought the air conditioner.
●If the air conditioner is not cooling or heating properly, the refrigerant may be leaking, so
see the dealer where the unit was purchased. Check with a qualified repairman before
attempting any repairs, which might accompany addition of refrigerant.
The refrigerant used in the air conditioner is safe. Although leaks should not occur, if for some reason any
refrigerant happens to leak into the room, make sure it does not come in contact with any flame, such as fan
heaters, kerosene heaters, or gas ranges, as this may result noxious substances being generated.
CAUTION
●Do not use the air conditioner for preservation purposes.
Do not use it for preserving precision instruments, foods, plants, animals, works of fine arts etc.
Performance or quality may deteriorate and animal or plant life may be shorter.
●Do not operate the air conditioner with a wet hand.
It may cause an electric shock.
●Ventilate the room from time to time.
Be careful especially when using a burning appliance in the same room. Insufficient ventilation
may cause shortage of oxygen.
●Before cleaning, be sure to stop the operation and turn the breaker OFF.
As a fan is rotating at a high speed, cleaning during operation may cause injury.
●After a long use, check the unit stand and fittings for damage.
The unit may drop and cause injury if damage is left unrepaired.
●Do not stand or sit on the outdoor unit. Do not place any object on the unit.
The object or the person may fall down or drop, causing injury.
●Do not pull at the conduit or hang anything on it.
Otherwise it will cause fire or electric shock.
WARNING
Failure to follow a warning is very likely
to result in such grave consequences as
death or serious injury.
CAUTION
Failure to follow a caution may result in
serious injury or property damage, and
in certain conditions, may result in a
grave consequence.

●These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue
using it.
Case
Operation does not start soon.
●When ON/OFF button was
pressed soon after operation
was stopped.
●When the mode was reselected.
The outdoor unit emits water or
steam.
Mists come out of the indoor unit.
The indoor unit gives out odour.
The outdoor fan rotates while the
air conditioner is not in operation.
The operation stopped suddenly.
(OPERATION lamp is on)
Explanation
●This is to protect the air conditioner.
You should wait for about 3 minutes.
■In COOL or DRY mode
•Moisture in the air condenses into water on the cool surface of
outdoor unit piping and drips.
■This happens when the air in the room is cooled into mist by the cold
air flow during cooling operation.
■This happens when smells of the room, furniture, or cigarettes are
absorbed into the unit and discharged with the air flow.
(If this happens, we recommend you to have the indoor unit washed
by a technician. Consult the dealer where you bought the air
conditioner.)
■After operation is stopped:
•The outdoor fan continues rotating for another 60 seconds for system
protection.
■While the air conditioner is not in operation:
•When the outdoor temperature is very high, the out door fan starts
rotating for system protection.
■For system protection, the air conditioner may stop operating on a
sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.

seasons of use, resulting in poor performance. It is recommended to have periodical
maintenance by a specialist aside from regular cleaning by the user. For specialist
maintenance, contact the dealer where you bought the air conditioner.
The maintenance cost must be born by the user.
Disposal requirements
Dismantling of the unit, treatment of the refrigerant, oil and eventual other parts, should
be done in accordance with the relevant local and national regulations.
