When flushing the system, you should:

• A. Disconnect the lines and flush through them separately
• B. Flush through a single pass
• C. Flush with the system under pressure
• D. Use Water to Flush

Answer: (A)

Flushing should be done so that each path is cleaned separately to prevent cross-contamination and ensure a thorough cleaning. Disconnecting the lines and flushing them one at a time allows you to isolate any debris, oil, or flushing agent in each line, observe the flow, and verify that both paths are clean before reassembly. This approach avoids pushing contaminants from one line into the other and ensures the suction and liquid lines are treated on their own routes, which is important because they may carry different residues. Flushing in a single pass can leave contaminants trapped in one branch, and trying to flush under pressure increases the risk of forcing debris into components or causing leaks. Using water as the flush introduces moisture into the system, which can lead to corrosion, freezing issues, or chemical reactions with oils and refrigerants, and it may not effectively remove oil or other residues.
