Cylinder color R410A is pink.
1. Reasons
R410A is a pseudo-azeotropic HFC blend (boiling point R32=-52°C[-62°F], R125=-49°C[-52°F]) and can almost be han-
dled the same way as a single refrigerant, such as R22. To be safe, however, draw out the refrigerant from the cylinder
in the liquid phase. If the refrigerant in the gaseous phase is drawn out, the composition of the remaining refrigerant will
change and become unsuitable for use.
2. Notes
When using a cylinder with a siphon, refrigerant is charged in the liquid state without the need for turning it upside down.
Check the type of the cylinder on the label before use.
