d) Flare Processing
Make certain that a clamp bar and copper
pipe have been cleaned.
By means of the clamp bar, perform the fl are
processing correctly.
Use either a fl are tool for R410A or
conventional fl are tool.
Flare processing dimensions differ according
to the type of fl are tool. When using a
conventional fl are tool, be sure to secure
"dimension A" by using a gauge for size
adjustment.
