When using a system-dependent recovery system with a non-operating compressor, what should the technician do?

• A. Use only the low side access fitting
• B. Use only the high side access fitting
• C. Place access fittings on both the low and high side of the system
• D. Seal off all access points

Answer: (C)

Using a system-dependent recovery system with a non-operating compressor necessitates accessing both the low and high side of the system to ensure effective refrigerant recovery. In this scenario, the compressor is not functioning, and thus it cannot assist in moving the refrigerant. By connecting to both access points, the technician can facilitate the recovery of refrigerant from the entire system, ensuring that all the refrigerant, which could be trapped in various parts of the system, is evacuated. This approach allows the technician to draw refrigerant from the high side, where refrigerant may still be present due to pressure differentials, and from the low side. Using only one access fitting would limit the recovery process and may leave remaining refrigerant in the system, which is not compliant with EPA regulations regarding the complete evacuation of refrigerants. Selecting this option demonstrates an understanding of how refrigerant recovery works in systems where the compressor is inoperative and emphasizes the importance of thorough and compliant practices in refrigerant management.
