R410A Refrigerant
• Piping wall thickness must comply with the applicable local, state, and federal codes for the 551 psi design pressure of R410A.
• Because R410A is a combination of R32 and R125, the required additional refrigerant must be charged in its liquid state. If the refrig-
erant is charged in its gaseous state, its composition changes and the system will not work properly.
GENERAL DATA
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. Many countries have
approved of and encouraged R410A for use as an environment friendly refrigerant.
• To prevent the refrigerant cylinder from exploding, do not place it in direct sunlight.
• Do not use any piping that has not been approved for use in high-pressure refrigerant systems.
• To prevent the piping from softening, do not heat it more than necessary during installation.
