Prior to introducing recovered refrigerant to a motor vehicle, you should:

A. Add oil to the system
B. Leak test the system
C. Recycle the refrigerant to SAE standards (1991 or J2099)
D. Evacuate the system



Answer :

Final answer:

Evacuate the system is crucial before introducing recovered refrigerant to a motor vehicle to maintain system effectiveness and longevity.


Explanation:

Evacuate the system is the correct answer. Before introducing recovered refrigerant to a motor vehicle, it is essential to remove all air and moisture from the system through vacuum evacuation. This process ensures the effectiveness and longevity of the refrigeration system.

Evacuating the system helps prevent issues like reduced cooling efficiency, potential damage to components, and contamination of the refrigerant. By creating a vacuum, any remaining air, moisture, or impurities are removed, allowing the refrigerant to function optimally.

Proper evacuation is a critical step in refrigeration system maintenance, ensuring it operates efficiently and effectively without any hindrances.
