2009 V50 2.4i Flush A/C Lines

[SSaxman]

I'm replacing the compressor in my wife's '09 V50 and will need to flush the system first. I have shop air and a flush kit and the new compressor/drier/orifice tube are not installed yet. I just want to know which lines to flush and can't seem to find any info. I'm certain I can't be the only one to have done this on a V50 or similar Volvo. After the flush, I'll get everything installed and take it to a shop and have them pull a vacuum and charge it up. Any help or insight is much appreciated! Thanks in advance for any help!!
