11 Installation Instruction

11.1. Select The Best Location

• There should not be any heat source or steam near the unit.
• There should not be any obstacles blocking the air

circulation.

• A place where air circulation in the room is good.
• A place where drainage can be easily done.
• A place where noise prevention is taken into consideration.
• Do not install the unit near the door way.
• Ensure the spaces indicated by arrows from the wall, ceiling,

fence or other obstacles.

• Recommended installation height for indoor unit shall be at

least 2.5 m.

• If an awning is built over the unit to prevent direct sunlight or

rain, be careful that heat radiation from the condenser is not
obstructed.

• There should not be any animal or plant which could be

affected by hot air discharged.

• Keep the spaces indicated by arrows from wall, ceiling,

fence or other obstacles.

• Do not place any obstacles which may cause a short circuit

of the discharged air.

• If piping length is over the rated length, additional refrigerant

should be added as shown in the table.

• This illustration is for explanation purposes only.

The indoor unit will actually face a different way.
