Just check your oil level at the seperator and adjust accordingly. To check this is is in the IOM. I use my clear branded hose and hook up to the lowest point of seperator and the other side to the discharge line. Then open valves and see how high my oil rises and mark the seperator. Check your measurement and add if needed.
All from the human interface settings. This particular exv I would open then have to shut power to the chiller once open. This kept it open. Be aware some exv models can break if you do this. This particular valve was ok to do so. Newer chillers will stay open till you close it again.
No because you are pushing the vapor through the condenser back to the barrel. This is to ensure you push all the liquid out. If I push the vapor from the suction side ill just get the barrel. It dosnt flow through the compressor fast unloaded. What you said would work good,(especially if the barrel is nice and cold) I believe, but I like pushing everything through the condenser to ensure I get all liquid.
Sorry I don't monitor the channel much. I'd be there all day and possibly some over time. I always push pull if possible. I started this recovery at 8:00a.m., and done with everything unhooked and tools in truck by 10:00a.m. after lunch I started changing fittings, had it charged and running by 10 the next morning.
