Flushing the ENTIRE system is NOT the same as evacuation. After a catastrophic compressor failure, debris is strewn throughout the entire system. All connections must be disconnected and flushing agent put in each line, then blown out with compressed air. If ALL debris is not removed from the system, the debris will be sucked into the new compressor and destroy it.

Once all lines are flushed, the correct amount of oil needs to be distributed among the components and a new filter drier installed as last thing immediately followed by a thorough evacuation.

It is best to also install a suction side filter in the line leading to the compressor.
