R410A is a pseudo-azeotropic refrigerant (boiling point R32 = -52˚C, R125 = -49˚C) and can roughly be handled
in the same way as R22; however, be sure to fill the refrigerant from the liquid side, for doing so from the gas
side will somewhat change the composition of the refrigerant in the cylinder.
When refrigerant leaks, additional refrigerant may be charged. (Add the refrigerant from the liquid side.)
