I am pretty green in the handling of the r410 refrigerant. I know that you are suppose to add it to the system as a liquid. But my question is to which line do you add it liquid(small) or gas (large). And do you have the unit running at the time your adding.
I have a feeling that with the high pressures that the lack of pressure differential could be an issue.
I was told to weight it in and that I should turn the bottle over and add it as a liquid in the gas line (suction or larger line) when adding only crack the line and watch the sight glass and make sure the 410 is only trickling in. Is this right?
And if it is do I run the unit to keep the pressure diferential large enough to cause the refrigerant to flow higher pressure to lower pressure?
Any advise would be appreciated
