An electric shock may happen. 

Do not touch the heat exchanger fins. 

These fins are sharp and could result in cutting injuries.

Do not place items which might be damaged by moisture 
under the indoor unit. 

Condensation may form if the humidity is above 80%, the 
drain outlet is blocked or the filter is polluted. 

After a long use, check the unit stand and fitting for 
damage.

 

If damaged, the unit may fall and result in injury.

To avoid oxygen deficiency, ventilate the room 
sufficiently if equipment with burner is used together 
with the air conditioner.

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 operate the air conditioner when using a room 
fumigation - type insecticide.

those who are hypersensitive to chemicals.

Do not place appliances which produce open fire in 
places exposed to the air flow from the unit or under the 
indoor unit.

 

It may cause incomplete combustion or deformation of the 
unit due to the heat.

Do not install the air conditioner at any place where 
flammable gas may leak out.

or infirm persons without supervision.
