This symbol indicates the possibility of death or serious injury.

This symbol indicates the possibility of injury or damage to property.

1)  This equipment must be grounded and installed with ground leakage current breaker. It may cause 

electrical shock if grounding is not perfect.

      

 

   

   

 

2)  Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and 
       accumulates at surrounding of the unit, it may cause fire.
3)  Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water 
        may enter the room and damage the furniture.

1)  Install according to this installation instructions strictly. If installation is defective, it will cause water

leakage, electrical shock,or fire.

      

 

 

 

2) Use the included accessories parts and specified parts for installation. otherwise, it will cause the set 

to fall, water leakage, electrical shock fire.

        

 

  

 

 

 

3)  Install at a strong and firm location which is able to withstand the set s weight. If the strength is not 

enough or installation is not properly done, the set will drop and cause injury.

     

   

   

 

 

 

 

 

 

 

 

 

4)  For electrical work, follow the local national wiring standard, regulation and this installation instructions. 

An independent circuit and single outlet must be used. If electrical circuit capacity is not enough or

      

 

 

 

 

 

 

 

 

   

 

 

   

 

   

defect found in electrical work, it will cause electrical shock fire.

     

 

   

 

   

 

 

 

 

5)  Use the specified cable and connect tightly and clamp the cable so that no external force will be acted 

on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.

     

 

 

   

   

   

 

   

 

 

   

   

 

6)  Wiring routing must be properly arranged so that control board cover is fixed properly. If control board

cover is not fixed perfectly, it will overheat at connection point of terminal, fire or electrical shock.

     

   

 

 

   

 

   

 

   

 

7)  When carrying out piping connection, take care not to let air substances other than the specified 

refrigerant go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure

     

 

 

 

 

 

   

 

 

 

 

 

 

 

in the refrigeration cycle, explosion and injury.

        

 

 

 

 

 

8)  Do not modify the length of the power supply cord or use of extension cord, and do not share the 

single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.
