The pressure for this product is 601 psi (4.15MPa). The pressure required for refrigerant R410A is
1.4 times higher than that of the refrigerant R22. That means that the refrigerant piping for R410A

refrigerant piping may rupture due to an excessive refrigerant pressure. Pay close attention to the
piping thickness when using copper refrigerant piping. The thickness of copper refrigerant piping
differs depending on its material.
