WARNING

Be sure to use fuses with the correct ampere 

reading.

Do not use improper fuses, copper or other wires as a 

substitute, as this may result in electric shock, fire, injury 
or damage to the unit.

Be sure to earth the unit.

Do not earth the unit to a utility pipe, lightning conductor 

or telephone earth lead. Imperfect earthing may result in 
electric shocks or 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 fire.

Consult the 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 a malfunction, electric shock, or fire may 
result.

Do not start or stop operating the air conditioner 

with the power supply breaker turned ON or OFF.

Otherwise, fire or water leakage may result. 

Furthermore, the fan will rotate abruptly if power failure 
compensation is enabled, which may result in injury.

Do not use the product in the atmosphere 

contaminated with oil vapor, such as cooking oil or 
machine oil vapor.

Oil vapor may cause crack damage, electric shocks, or 

fire.

Do not use the product in places with excessive oily 

smoke, such as cooking rooms, or in places with 
flammable gas, corrosive gas, or metal dust.

Using the product in such places may cause fire or 

product failures.

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

insecticide) near the product.

Do not clean the product with organic solvents such 

as paint thinner.

The use of organic solvents may cause crack damage to 

the product, electric shocks, or fire.

Be sure to use a dedicated power supply for the air 

conditioner.

The use of any other power supply may cause heat 

generation, fire, or product failures.

Consult your 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 indoor/outdoor unit’s fan guard. 

The guard protects against the unit’s high speed fan, 

which may cause injury. 

Do not place objects that are susceptible to 

moisture directly beneath the indoor or outdoor 
units. 

Under certain conditions, condensation on the main unit 

or refrigerant pipes, air filter dirt or drain blockage may 
cause dripping, resulting in fouling or failure of the object 
concerned. 

To avoid oxygen depletion, 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 unit as this may result in fire.

Before cleaning, be sure to stop unit operation, turn 

the breaker off or remove the power cord.

Otherwise, an electric shock and injury may result.

To avoid electric shocks, do not operate with wet 

hands. 

Do not place appliances that produce naked flames 

in places exposed to the air flow from the unit as 
this may impair combustion of the burner.  

Do not place heaters directly below the unit, as 

resulting heat can cause deformation. 

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 heather
