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

When using a system-dependent recovery system, recovering from the high side only is crucial for the proper and efficient recovery of refrigerant. In system-dependent recovery systems, the refrigerant flows depending on the conditions in the system, and they often do not have a built-in method for recovering refrigerant from the low side reliably. By recovering from the high side, technicians can take advantage of the pressures within the system, allowing for a more effective transfer of refrigerant back into the recovery machine.

This method ensures that as much refrigerant as possible is removed during the recovery process. It is common practice to engage the high side because it allows the recovery device to extract refrigerant that might otherwise remain trapped within the system, especially when dealing with factors like heat and pressure differences.

The other choices present misunderstandings about the operation of system-dependent recovery systems and best practices for recovering refrigerant effectively. For instance, recovering from the low side only would not allow for maximizing refrigerant recovery, especially in scenarios where refrigerant is vaporizing. Installing access fittings on both sides could be unnecessary depending on the design of the recovery system. Lastly, stating that refrigerant should never go to the high side is unworkable since it can prevent essential recovery from high-pressure areas in
