Installation method
Pipe bending
1.Perform bending of the pipe using the bender which has a specified bending radius.
2.Be sure to take full care to perform bending of the pipe successfully at one time. Bending and unbending the pipe more than twice makes the bending work increasingly difficult.
3.You may use the spring inserted into the gas pipe instead of the bender to bend the pipe.
4.When you bend the pipe using the spring, hold the pipe with both hands to prevent any distortion, and secure a minimum bending radius of more than 100mm.

Tightening of connection parts
ffAlign the pipes to be connected and tighten the flare nuts first manually and then with a torque wrench, applying the following torque.
Outer diameter (mm) | Tightening torque (kgf·cm) |

ø 19.05 | 990~1210 |

ffYou can avoid of gas leakage by applying refrigerant oil on the flare connection part.

Drilling a hole in the wall
ffDrill a hole at a slightly downward slant (15˚) with a diameter of 60~65 mm.
ffThe drilling should be done at a distance of less than 150 mm from the floor facing the indoor unit.
❋❋If a hole on the wall is above 150 mm from the floor, use a hole for drain hose (ø 35 mm) for connecting drain hose.
