Really confusing question! Try again. I suppose that language is not issue.

First, you must find out (from serial number on the compressor) the weighted charge of refrigerant for the compressor. Pull a deep ( microns) vacuum and check to see if the gage moves. Be patient and hold the vacuum for 30min or more.

pressure test to see if there is some leakage in the refrigeration system.
Evacuate the refrigeration to required micro value
charge refrigerants
