Charging Refrigerant

R410A must be in a liquid state when charging.

Reasons :

1.R410A is a pseudo-azeotropic refrigerant (boiling point R32= -52*, R125= -49*) 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.

Note :

*In the case of a cylinder with a syphon, liquid R410A is charged without turning the cylinder up side down. Check the type of cylinder before charging.

Remedies to be taken in case of a refrigerant leak

When refrigerant leaks, additional refrigerant may be charged. (Add the refrigerant from the liquid side)

Characteristics of the Conventional and the New Refrigerants

*Because R410A is a simulated azeotropic refrigerant, it can be handled in almost the same mammer as a single refrigerant such as R22. Howerver,if the refrigerant is removed in the vapor phase , the composition of the refrigerant in the cylinder will somewhat change.

*Remove the refrigerant in the liquid phase. Additional refrigerant may be added in case of a refrigerant leak.
