Consult your local dealer regarding 

relocation and reinstallation of the air 

conditioner. 

Improper installation work may result in leakage, 

electric shocks or a fire. 

Be sure to earth the air conditioner. 

Do not earth the air conditioner to a utility piping, 

lightning conductor or telephone earth lead. 

Imperfect earthing may result in electric shocks 

or a fire. 

A high surge current from lightning or other 

sources may cause damage to the air 

conditioner. 

Be sure to install an earth leakage breaker. 

Failure to install an earth leakage breaker may 

result in electric shocks or a fire. 

Be sure to use a dedicated power supply for 

the air conditioner. 

The use of any other power supply may cause 

heat generation, a fire, or air conditioner failure 

Consult your local dealer regarding what to 

do in case of refrigerant leakage. 

When the air conditioner is installed in a small 

room, it is necessary to take proper measures 

so that the amount of any leaked refrigerant 

does not exceed the concentration limit in the 

event of a leakage. Otherwise, this may lead to 

an accident due to oxygen depletion. 

-�CAUTION--------­

Children should be watched so that they do

not play with the indoor unit or its remote

controller.

Accidental operation by a child may result in

injury or electric shocks.

Do not allow a child to mount on the outdoor

unit or avoid placing any object on it.

Falling or tumbling may result in injury.

Do not let children play on or around the

outdoor unit.

If they touch the unit carelessly, injury may be

caused.

Be sure that children, plants or animals

are not exposed directly to airflow from the

indoor unit, as adverse effects may ensue.

Do not place flammable sprays or operate

spray containers near the air conditioner as

this may result in a fire.

Do not wash the air conditioner or the

remote controller with water, as this may

result in electric shocks or fire.

Do not place water containers (flower vases, 

etc.) on the indoor unit, as this may result in 

electric shocks or a fire. 

Do not put flammable containers, such as 

spray cans, within 1 m from the air outlet. 

The containers may explode because the warm 

air from the indoor or outdoor unit will affect 

them. 

Turn off the main power switch when the 

air conditioner is not to be used for prolonged 

periods. 

When the main power switch is left on, some 

electrical power (watts) is still consumed even if 

the air conditioner is not operating. Therefore, 

switch off the main power switch to save energy. 

When resuming operation, to ensure smooth 

running, turn on the main power switch 6 hours 

before operating the air conditioner again. 

Do not place objects in direct proximity of 

the outdoor unit and do not let leaves and 

other debris accumulate around the unit. 

Leaves are a hotbed for small animals which can 

enter the unit. Once in the unit, such animals 

can cause malfunctions, smoke or a fire when 

making contact with electrical parts. 

Before cleaning, be sure to stop the air 

conditioner operation, turn the power circuit 

breaker off. 

Otherwise, an electric shocks and injury may 

result. 

To avoid electric shocks, do not operate with 

wet hands. 
Never touch the internal parts of the remote 

controller. 

Touching certain internal parts will cause electric 

shocks and damage to the remote controller. 

Consult your local dealer about checking and 

adjustment of internal parts. 

To avoid oxygen deficiency, ensure that the 

room is adequately ventilated if equipment 

such as a burner is used together with the air 

conditioner. 

Do not leave the remote controller wherever 

there is a risk of wetting. 

If water gets into the remote controller there 

is a risk of electrical leakage and damage to 

electronic components. 

Watch your steps at the time of air filter 

cleaning or inspection. 

High-place work is required, to which utmost 

attention must be paid. 

If the scaffold is unstable, you may fall or topple 

down, thus causing injury.
