GENERAL DATA
R410A Refrigerant
• Piping wall thickness must comply with the applicable local, state, and federal codes for the 551 psi design
pressure of R410A.
• Do not use any piping that has not been approved for use in high-pressure refrigerant systems.
•
Do not heat refrigerant piping more than necessary during installation. Excessive heat can cause the pipe to soften.
• 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.
R410A Refrigerant - 0% Ozone Depleting
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.
•
Do not place the refrigerant cylinder in direct sunlight. Exposure to direct sunlight can cause the refrigerant cylinder to explode,
resulting in death or severe injury.
