To what level must MVAC systems be evacuated before being scrapped?

MVAC (Motor Vehicle Air Conditioning) systems must be evacuated to a level that ensures all refrigerant and moisture have been removed before being scrapped. This is crucial because residual refrigerant can contribute to environmental harm, and moisture can lead to system damage during the recycling process.

The correct evacuation level for scrapping involves achieving 4 inches of mercury (inHg), which ensures that the system is sufficiently evacuated. This level effectively removes refrigerants and minimizes the risk of any trapped moisture or remaining refrigerants that could escape into the atmosphere.

Following standard procedures and regulations is essential for protecting the environment and complying with EPA regulations. Therefore, achieving an evacuation level of 4 inches is both a practical and regulatory requirement when it comes to proper disposal of MVAC systems.
