MVAC systems must be evacuated to how many inches of mercury before being scrapped?

2 inches
4 inches
6 inches
8 inches

The correct answer is: 4 inches

The correct evacuation measurement for MVAC systems before they can be scrapped is 4 inches of mercury. This requirement is based on EPA regulations to ensure that any refrigerants within the system are properly removed to prevent environmental harm. Achieving this level of vacuum helps to ensure that virtually all refrigerant is eliminated from the system, mitigating the potential for refrigerant leakage into the atmosphere, which can contribute to ozone depletion and global warming. The 4 inches of mercury standard reflects a necessary safety measure to protect the environment while handling refrigerants in MVAC systems.
