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 R32 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.
