Cutting or extending the pipe

5. Check if you flared the pipe correctly (see examples of incorrectly flared pipes below).

Correct	Inclined	Damaged	Cracked	Uneven
		Surface		Thickness

6.Align the pipes to connect them easily. Tighten the flare nuts first with your hands, and then with a torque wrench, applying the following torque:

Flare nut

Indoor outlet	pipe
		Connecting pipe

Outer Diameter	Torque (kgf•cm)
ø6.35 mm	140~170
ø9.52 mm	250~280
ø12.70 mm	380~420
ø15.88 mm	440~480
ø19.05 mm	990~1210
ø22.23 mm	990~1210

• Excessive torque can be cause of gas leakage. In case brazing the pipe, the nitrogen gas must be blown into the

pipe (50 Pa). The joint must be accessible and serviceable.

7. For further details on how to connect to the outdoor unit and purge the air, refer to page 34~36.

• Tighten the flare nut with torque wrench according to specified method.

If the flare nut is over-tightened, the flare may break and cause refrigerant gas leakage.
