20.  Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare may 

break and cause refrigerant gas leakage. 

21.  After completion of installation, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts with 

fire. 

22.  Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fire. 

23.  This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and telephone. 

Otherwise, it may cause electrical shock in case of equipment breakdown or insulation breakdown. 

 
 

 

1.  

Do not install the unit in a place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the 
unit, it may cause fire. 

 

2. 

Do not release refrigerant during piping work for installation, re-installation and during repairing refrigeration parts. Take care of the 
liquid refrigerant, it may cause frostbite. 

 

3.  Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc. 

4.  Do not touch the sharp aluminium fin, sharp parts may cause injury.  

 

5. 

Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the 
furniture. 

6.  Select an installation location which is easy for maintenance.

1)  Power supply connection to the receptacle using power plug. 
     Use an approved 15/16A (3/4~1.75HP), 16A (2.0HP), 20A (2.5HP) or 25A (3.0HP) power plug with earth pin for the connection to the 
     socket. 
2)  Power supply connection to a circuit breaker for the permanent connection. 
     Use an approved 16A (3/4~2.0HP), 20A (2.5HP) or 25A (3.0HP) circuit breaker for the permanent connection. It must be a double pole 
     switch with a minimum 3.0 mm contact gap.
