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.
