Beware of a fire in case of refrigerant leakage. 

If the air conditioner is not operating correctly, i.e. not 

generating cool or warm air,  refrigerant leakage could be 

the cause. Consult your local dealer for assistance. The 

refrigerant used for the air conditioner is safe and normally 

does not leak. However, if the refrigerant leaks and gets in 

contact with a naked burner, heater or cooker, it may 

generate hazardous compounds. Turn off the air 

conditioner and call your local dealer. Turn on the air 

conditioner after the qualified service person makes sure 

to confirm that the leakage is repaired. 

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. 

Contact professional personnel about attachment 

of assessories and be sure to use only accessories 

specified by the manufacturer. 

If a defect results from your own workmanship, it may 

result in water leakage, electric shocks or a fire. 

Consult your local dealer regarding relocation and 

installation of the air conditioner.(Do not do installation 

of the air conditioner by yourself) 

Improper installation work may result in leakage, electric 

shocks or a fire. 

Be sure to use fuses with the correct ampere reading. 

Do not use improper fuses, copper or other wiring as 

a substitute, as this may result in electric shocks, a fire 

injury or damage to the air conditioner. 

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. 

Consult your local dealer if the air conditioner 

submerges owing to a natural disaster,such as a flood 

or typhoon. 

Do not operate the air conditioner in that case, or otherwise 

malfunction, electric shocks, or a fire may result. 

Start or stop the air conditioner with the remote 

controller. Never use the power circuit breaker for this 

purpose. 

Otherwise, it may cause a fire or water leakage. 

Furthermore, if an automatic restart control is provided 

against power failure and the power is recovered, the fan will 

rotate suddenly and may cause injury. 

Do not use the air conditioner in the atmosphere 

contaminated with oil vapor, such as cooking oil or machine 

oil vapor. 

Oil vapor may cause crack damage to the air conditioner, 

electric shocks, or a fire. 

Do not use the air conditioner in places with excessive 

oily smoke, such as cooking rooms, or in places with 

flammable gas, corrosive gas, or metal dust. 

Using the air conditioner in such places may cause a fire 

or air conditioner failures. 

Do not relocation and reinstallation of the air 

conditioner by yourself. 

Improper installation work may result in leakage, electric 

shocks or a fire. 

Please consult your local dealer. 

Do not use flammable materials (e.g., hairspray or 

insecticide) near the air conditioner. 

Do not clean the air conditioner with organic solvents 

such as paint thinner. 

The use of organic solvents may cause crack damage to 

the air conditioner, electric shocks, or a fire. 

Do not place burners or heaters in places exposed 

to the air flow from the unit as this may impair 

combustion of the burner or heater. 

Do not wipe the controller panel with benzene or other 

organic solvent. 

This will cause discoloration and/or peeling. If the panel 

needs cleaning, use a damp cloth with some water-diluted 

neutral detergent. Wipe with a dry cloth afterwards. 

Do not operate with the control panel lid open. 

If water gets inside the panel, it may result in equipment 

failure or electric shock. 

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 failures. 

Consult your local dealer regarding cleaning the inside 

of the air conditioner. 

Improper cleaning may cause breakage of plastic parts, 

water leakage and other damage as well as electric shocks. 

-& 

CAUTION----------­

Do not use the air conditioner for purposes other than 

those for which it is intended. 

Do not use the air conditioner for cooling precision 

instruments, food, plants, animals or works of art as this 

may adversely affect the performance, quality and/or 

longevity of the object concerned. 

Do not remove the outdoor unit's outlet side grille. 

The guard protects against the unit's high-speed fan, 

which may cause injury. 

To avoid oxygen deficiency, ensure that the room is 

adequately ventilated if equipment such as a burner 

is used together with the air conditioner. 
After prolonged use, check the unit stand and its mounts 

for damage. 

If left in a damaged condition, the unit may fall and cause 

injury. 

Do not place flammable sprays or operate spray 

containers near the air conditioner as this may result 

in 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. 

When maintenance, 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. 

Do not place objects that are susceptible to moisture 

directly beneath the indoor or outdoor units. 

Under certain conditions, condensation on the unit or 

refrigerant piping, air filter dirt or drain blockage may 

cause dripping, resulting in fouling or failure of the object 

concerned.
