The flare machining dimensions for units that use R410A is larger than those for units that use R22 in order to
increase air tightness.
If a clutch type flare tool is used to machine flares on units that use R410A, make the protruding part of the
pipe between 1.0 and 1.5mm. Copper pipe gauge for adjusting the length of pipe protrusion is useful.
