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

• A. Run the compressor and recover from the high side only
• B. Turn off the compressor and recover from the low side only
• C. Remove refrigerant through both high and low sides
• D. Perform a vacuum before recovery

Answer: (A)

When using a system-dependent recovery system on an appliance with an operating compressor, the technician should recover refrigerant from the high side while the compressor is running. This is because a system-dependent recovery process relies on the operation of the compressor to facilitate the movement of refrigerant during recovery. In a functioning system, the compressor creates a pressure differential that helps push the refrigerant into the recovery unit. By running the compressor, the refrigerant on the high side can flow into the recovery system more effectively, ensuring a more complete and efficient recovery process. This method takes advantage of the existing pressure and flow dynamics within the system to maximize the amount of refrigerant extracted. It is essential to note that recovery from the low side only would limit the amount of refrigerant recovered, as it would not use the compressor’s capability to move refrigerant under pressure. Performing a vacuum before recovery is unnecessary in this case, as the aim is to recover the refrigerant, not remove air and moisture. Removing refrigerant through both sides when the compressor is operational may not be compatible with the guidelines for a system-dependent recovery system, as it could lead to system imbalances and incomplete recovery.
