Safety precautions
Before starting to use the system, please read these “Safety precautions” carefully.
When you have read this instruction manual, please keep it without missing.
Symbols which appear frequently in the text have the following meaning:
Strictly prohibited Observe instructions with
great care Provide positive earthing
WARNING Improper handling could lead to drastic result
like death, serious injury, etc. CAUTION Might pose a serious problem, depending on the circumstances.
Please observe these precautions with great care, since they are essential to your safety.
❚INSTALLATION PRECAUTIONS
WARNING
The system is for domestic, residential etc. use.
If used in severer environments, such as an engineering workplace, the equipment may function poorly.
The system must be installed by your dealer or a qualified professional.
It is not advisable to install the system by yourself, as faulty handling may cause leakage of water, electric shock or fire.
CAUTION
Do not install it where flammable gas may leak.
Gas leaks may cause fire.
Depending on the place of installation, an earth leakage breaker may be necessary.
If you do not install an earth leakage breaker, you may get an electric shock.
Make sure to install the drain hose properly so that all the water is drained out.
Improper installation may lead to water drop in the room resulting in wet furniture.
Make sure that the system has been properly earthed.
Earth cables should never be connected to a gas pipe, water pipe, lightning conductor or telephone earth cable. Incorrect installation of the
earth cable may produce an electric shock.
❚PRECAUTIONS FOR RELOCATION OR REPAIRS
WARNING
Do not perform any repairs or modifications by yourself. Consult the dealer if the unit requires
repair.
If you repair or modify the unit, it can cause water leaks, electric shocks or fire.
Consult your dealer for repairs.
Wrong repairs could cause an electric shock, fire, etc.
In case the air-conditioner is relocated elsewhere, contact your dealer or a professional fitter.
Faulty installation may cause water leakage, electric shock, fire, etc.
If you notice anything abnormal (smell of burning, etc.), stop the system, turn off the power source
and consult your dealer.
Continued use of the system in abnormal circumstances may result in malfunctioning, electric shock, fire, etc.
If the air-conditioner fails to cool or warm the room, it may have a refrigerant leakage. Contact
your dealer.
If refrigerant needs to be added, check with your dealer for proper instructions.
If the refrigerant comes in contact with the bare skin, it may cause cold injury.
If the refrigerant gas is inhaled excessively, it may cause deterioration of nerve function like dizziness and headache, or deterioration of heart
function like irregular heartbeat and heart palpitation temporarily. If refrigerant unexpectedly leaks from the unit onto a fan heater, stove,
hotplate or other heat source, harmful gases could be generated.

❚OPERATION PRECAUTIONS
WARNING
Do not expose yourself to the cooling air for a long period.
This could affect your physical condition and cause health problems.
Do not insert anything into the air inlet.
This may cause injury, as the internal fan rotates at high speed.
The appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a person responsible for their
safety.
Children should be supervised to ensure that they do not play with the appliance.
Store the remote control out of reach of infants.
Failure to observe this may result in the batteries being swallowed or other accidents.
CAUTION
Only use approved fuses.
Use of steel or copper wire instead of an approved fuse is strictly prohibited, as it may cause a breakdown or fire.
Do not handle the switches with wet hands.
This may cause an electric shock.
Do not swing from the indoor unit.
If the indoor unit falls down,you may get injured.
Do not place a flammable insecticide or paint spray near the blower, nor spray it directly on the
system.
This may result in a fire.
You should not expose any combustion appliance directly to the air stream of the air-conditioner.
The appliance may then work inadequately.
Do not wash the air-conditioner with water.
This could cause an electric shock.
The system should only be used for its original purpose and not for anything else like, for
instance, preservation of food, plants or animals, precision devices or works of art.
The system is only intended for use in ordinary domestic rooms. Any other use of the system may damage the quality of food, etc.
Do not place anything containing water, like vases, on top of the unit.
Water entering the unit could damage the insulation and therefore cause an electric shock.
Do not install the system where the airflow direction is aimed directly at plants or animals.
This will damage their health.
Do not sit on the outdoor unit nor put anything on it.
If the unit falls down or things drop off it, people could get hurt.
After a long period of use, check the unit’s support structure from time to time.
If you do not repair any damage right away, the unit may fall down and cause personal injury.
Do not touch the aluminum fins on the air heat exchanger.
It may result in injury.
Do not place household electrical appliances or household items under neath the indoor or
outdoor units.
Condensation falling from the unit may stain objects and cause accidents or electrical shock.
Do not operate the system without the air filter.
It can cause malfunction of the system due to clogging of the heat exchanger.
Do not shut off the power source immediately after stopping the operation.
Wait at least 5 minutes, otherwise there is a risk of water leakage or breakdown.
Do not control the system with main power switch.
It can cause fire or water leakage. In addition, the fan can start unexpectedly, which can cause personal injury.
If you operate the system together with a combustion appliance, you must regularly ventilate the indoor air.
Insufficient ventilation may cause accidents due to oxygen deficiency.
Stand firmly on a stepladder or other stable object when removing the inlet panel and filters.
Failure to observe this may result in injury through insecure objects toppling over.
When you clean the system, stop the unit and turn off the power source.
Never open the panel while the internal fan is rotating.
Do not place objects near the outdoor unit or allow leaves to gather around the unit.
If there are objects or leaves around the outdoor unit, small animals may enter unit and contact electrical parts and may cause a break-down,
smoke or fire.
Contact your dealer to clean inside the indoor unit, do not attempt to do by yourself.
The use of a non-approved detergent or improper washing method may damage the unit’s plastic components and cause leaks. Damage,
smoke, or fire may also happen if the detergent comes in contact with electrical parts or the unit’s motor.
Stop the unit and turn off the power if you hear thunder or there is a danger of lightning.
It may damage the unit.
