R410A REFRIGERANT

WARNING

Note:

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.

• 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.

• 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 refrigerant is charged in its gaseous state, its composition changes and the system will not work properly.
