Liquid line ( small line )
Suction Line ( large line )

You close the service valve at liquid line.....and pump down until you get 0 psig on the gauges. After that close the service valve at suction line.

if you have a total vacuum on the entire system dump into the LL let it equalize flip the can again remove the guage hose and start the system let it run and then add gas only to the insulated larger line at the compressor...should be a shradder valve on those servcie valves both full CCW open to the system running you don't need to work the valves just the shradder taps
