R410A REFRIGERANT
R410A Refrigerant
R410A refrigerant has a higher operating pressure in comparison to R22 refrigerant and, therefore, all piping system materials installed must
have a higher resisting pressure than the materials traditionally used in R22 systems.
R410A refrigerant is an azeotrope of R32 and R125, mixed at 50:50, so the ozone depletion potential (ODP) is 0.

Note
• Because R410A is a combination of R32 and R125, the required additional refrigerant must be charged in its liquid state. If the refrigerant is
charged in its gaseous state, its composition changes and the system will not work properly.
• Do not heat piping more than necessary during installation. Piping may become soft and fail when pressurized.
