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 / R32 or conventional 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.
