During the R-12 freezing-risk charging process, the next step after achieving the initial vapor stage is to perform a liquid charge.

In this charging method, the refrigerant is added in stages to control how it fills the system and to avoid problems like liquid flooding of the compressor. You begin by introducing refrigerant as vapor so it can circulate and begin filling the evaporator and lines without delivering liquid that could slug the compressor. Once the initial vapor portion has been established and readings indicate the system has taken that vapor stage, the next step is to top off with liquid refrigerant to reach the full charge. This sequencing helps ensure the system ends up with the correct total amount of refrigerant while maintaining proper oil return and avoiding freezing issues in the evaporator. So, the statement is true.
