Refrigerant piping A CAUTION • Use the flare nut fixed to the main unit.(This is to prevent the flare nut from cracking as a result of deterioration over time.) • To prevent gas leakage,apply refrigeration oil only to the inner surface of the flare.(Use refrigeration oil for R410A.) • Use a torque wrench when tightening the flare nuts to prevent damage to the flare nuts and gas leakage. • Align the centers of both flares and tighten the flare nuts 3 or 4 turns by hand,then tighten them fully with a spanner and a torque wrench.
