GENERAL DATA
R410A Refrigerant
R410A Refrigerant
R410A refrigerant has a higher operating pressure in comparison to R22 refrigerant. 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.
WARNING
• 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 will become soft and fail when pressurized.
•
Do not use any piping that has not been approved for use in high-pressure refrigerant systems. Piping wall thickness must comply with
the applicable local, state, and federal codes for the 551 psi design pressure of R410A. Inadequate piping will fail when pressurized.
