Warning 

Be sure to use an exclusive power circuit for the equipment, and follow the technical standards related to 
the electrical equipment, the internal wiring regulations and the instruction manual for installation when 
conducting electrical work. 
Insufficient power circuit capacity and improper electrical work can cause an electrical shock or fire. 

 

Be sure to use the specified cable to connect between the indoor and outdoor units. Make the 
connections securely and route the cable properly so that there is no force pulling the cable at the 
connection terminals. 
Improper connections can cause excessive heat generation or fire. 

 

When connecting the cable between the indoor and outdoor units, make sure that the terminal cover 
does 
not lift off or dismount because of the cable. 
If the cover is not mounted properly, the terminal connection section can cause an electrical shock, 
excessive heat generation or fire. 

 

Do not damage or modify the power cable. 
Damaged or modified power cable can cause an electrical shock or fire. Placing heavy items on the 
power cable, and heating or pulling the power cable can damage the cable. 

 

Do not mix air or gas other than the specified refrigerant (R-410A / R22) in the refrigerant system. 
If air enters the refrigerating system, an excessively high pressure results, causing equipment damage 
and injury. 

 

If the refrigerant gas leaks, be sure to locate the leak and repair it before charging the refrigerant. After 
charging refrigerant, make sure that there is no refrigerant leak. 
If the leak cannot be located and the repair work must be stopped, be sure to perform pump-down and 
close the service valve, to prevent the refrigerant gas from leaking into the room. The refrigerant gas 
itself 
is harmless, but it can generate toxic gases when it contacts flames, such as fan and other heaters, 
stoves and ranges. 

.

 

 

When replacing the coin battery in the remote controller, be sure to disposed of the old battery to prevent 
children from swallowing it. 
If a child swallows the coin battery, see a doctor immediately.
