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.

Charging Refrigerant
R410A must be in a liquid state when charging.
Reasons :
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.
When refrigerant leaks, additional refrigerant may be charged. (Add the refrigerant from the
liquid side)
Remedies to be taken in case of a refrigerant leak
* 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.
