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
conventional flare tool, be sure to secure
"dimension A" by using a gauge for size
adjustment.
