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 the following two categories.
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 (heat) air for a long time, do not cool (heat) 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 shop
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 shop 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.

NOTE
<Note on HEAT mode operation>
●Since this air conditioner heats the room by
taking heat from outdoor air to indoors, the
heating capacity becomes smaller in lower
outdoor temperatures. If the heating effect is
insufficient, it is recommended to use another
heating appliance in combination with the air
conditioner.
●The heat pump system heats the room by
circulating hot air around all parts of the room.
After the start of heating operation, it takes
some time before the room gets warmer.
●In heating operation, frost may occur on the
outdoor unit and lower the heating capacity. In
that case, the system switches into defrosting
operation to take away the frost.
●During defrosting operation, hot air does not
flow out of indoor unit.
<Note on AUTO operation>
●In AUTO operation, the system selects a
temperature setting and an appropriate mode
(COOL or HEAT) based on the room
temperature at the start of the operation.
●The system automatically reselects setting at a
regular interval to bring the room temperature
to user-seetting level.

Trouble Shooting
●●
●●
●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.
Hot air does not flow out soon
after the start of heating
operation.
The heating operation stops
suddenly and a flowing sound is
heard.
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.
●The air conditioner is warming up.You should wait for 1 to 4 minutes.
(The system is designed to start discharging air only after it has reached
a certain temperature.)
●The system is taking away the frost on the outdoor unit.
You should wait for about 3 to 10 minutes.
■In HEAT mode
•The frost on the outdoor unit melts into water or steam when the air
conditioner is in defrost operation.
■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 service shop 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.
