🔍 Key Concepts

• EPA Clean Air Act refrigerant recovery rules for systems with leaks • Difference between recovering all possible refrigerant versus just vapor or just liquid • What to do with leaking vs non‑leaking sections of a system when you cannot reach full evacuation

💭 Think About

• If a system has a leak and you cannot pull it down to the required evacuation level, what parts of the system can still be properly evacuated? • Which options would clearly violate the intent of the Clean Air Act by either adding more refrigerant to a leaking system or leaving recoverable refrigerant in place? • How could a technician legally minimize emissions while still complying with required evacuation levels wherever they can be met?

✅ Before You Answer

• Make sure you are not adding refrigerant to a known leaking system just to test it • Check which answer choice involves separating/isolating parts of the system rather than treating the system as one whole unit • Confirm that the option you select aims to recover as much refrigerant as practicable and reach mandated evacuation levels wherever possible
