Final Answer:

Technicians must evacuate an appliance or component containing more than 200 pounds of R410A to a level of 15 psig.Thus,the correct option is 4.

Explanation:

When dealing with the evacuation of appliances or components containing refrigerants, it is crucial to follow industry guidelines for safety and environmental considerations. In the case of R410A, which is a commonly used refrigerant, the recommended evacuation level is 15 psig.

This pressure specification ensures that a thorough evacuation process is carried out to remove the refrigerant effectively. The value of 15 psig indicates the pressure in pounds per square inch gauge, which is a measure of pressure relative to atmospheric pressure.

To comprehend the significance of this pressure level, it's essential to recognize that psig accounts for the pressure above atmospheric pressure. Atmospheric pressure at sea level is approximately 14.7 psi.

Therefore, when evacuating a system to 15 psig, it means creating a pressure slightly above atmospheric pressure. This ensures that the refrigerant is adequately removed from the system, minimizing the risk of leaks or residual refrigerant, which could be harmful to both the environment and individuals involved in the repair process.

In practical terms, achieving an evacuation level of 15 psig involves using vacuum pumps to reduce the pressure within the system. Technicians employ these pumps to lower the pressure below atmospheric pressure, ensuring a complete and safe removal of the refrigerant. Adhering to the recommended evacuation level is not only a regulatory requirement but also a critical step in maintaining the efficiency and safety of the refrigeration system being serviced.

Thus,the correct option is 4.
