c)Insertion of Flare Nut

d)Flare Processing

Make certain that a clamp bar and copper pipe have been cleaned.

By means of the clamp bar, perform the flare processing correctly.

Use either a flare tool for R410A or conven- tional flare tool.

Flare processing dimensions differ according to the type of flare tool. When using a con- ventional flare tool, be sure to secure “dimen- sion A” by using a gauge for size adjustment.
