What information must be recorded on the label of A2L equipment after a system installation is completed?

• A. Date the refrigerant grade used.
• B. The serial number of the installer.
• C. Date the pressure test and evacuation were completed.
• D. The ambient temperature at installation.

Answer: (C)

Recording the date the pressure test and evacuation were completed is necessary because it shows that the system was leak-tested and dried before charging. This protects against leaks, moisture-related issues, and potential safety problems with A2L refrigerants, and it provides a traceable service record for future maintenance. The other details (refrigerant grade, installer serial, ambient installation temperature) aren’t required to be on the equipment label in this context.
