(2)Holding the pipe downward so that cuttings cannot enter the pipe, remove the burrs.
(3)Remove the flare nut from the indoor unit pipe and outdoor unit and assemble as shown in (Table1) and insert the flare nut onto the pipe, and flare with a flaring tool.
(4)Check if the flared part "L" (Fig.20)is spread uniformly and that there are no cracks.
