1.  SAFETY PRECAUTIONS

To gain full advantage of the air conditioner’s functions and to 
avoid malfunction due to mishandling, please read this oper-
ation manual carefully before use.
This air conditioner comes under the term “appliances not 
accessible to the general public”.

•  This manual classifies the precautions into WARN­

INGS and CAUTIONS.  

Be sure to follow all the precautions below: They are 

all important for ensuring safety.

 WARNING .........Indicates a potentially hazardous situa-

tion which, if not avoided, could result in 

death or serious injury.

 

CAUTION ..........Indicates a potentially hazardous situa-

tion which, if not avoided, may result in 

minor or moderate injury. 
It may also be used to alert against 
unsafe practices.

•  After reading, keep this manual in a convenient place 

so that you can refer to it whenever necessary. If the 

equipment is transferred to a new user, be sure also to 

hand over the manual. 

 WARNING

Be aware that prolonged, direct exposure to cool or 

warm air from the air conditioner, or to air that is too 

cool or too warm can be harmful to your physical con­

dition and health.
When the air conditioner is malfunctioning (giving 

off a burning odor, etc.), turn off the power to the air 

conditioner and contact your local dealer.
Continued operation under such circumstances may 
result in a failure, electric shocks or a fire.
Consult your local dealer about installation work. 

Doing the work yourself may result in water leakage, 

electric shocks or a fire.
Consult your local dealer regarding modification, 

repair and maintenance of the air conditioner. 

Improper workmanship may result in water leakage, 

electric shocks or a fire.
Do not place objects, including rods, your fingers, 

etc., in the air inlet or outlet.

Injury may result due to contact with the air conditioner’s 

high-speed fan blades.

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 nor-

mally 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 accessories 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 

reinstallation of the air conditioner.

Improper installation work may result in leakage, electric 

shocks or a fire.
Be sure to use fuses with the correct ampere read­

ing.

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 unit to a utility piping, lightning conduc-
tor 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 sub­

merges owing to a natural disaster, such as a flood 

or typhoon.
Do not operate the air conditioner in that case, or other-

wise malfunction, electric shocks, or a fire may result.

Start or stop the air conditioner with the remote con­

troller. Never use the power circuit breaker for this 

purpose. 

Otherwise, it may cause a fire or water leakage. Further­

more, 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 exces­

sive 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.
