Pulled a vacuum on it after I replaced the valve and gasket. Hardest part was getting my big mitts in there. Vacuum held so I pulled a vacuum on the gauges, lines, sight glass, etc. and then pulled the Freon from the storage tank. Put it in some warm water to bring the pressure up. Ended up adding about 12Oz to get close to the 1.09Kg required. I ended up letting a little out, system was down to about 22lbs (pressure @32 for R134a). Need dry ice or a machine to pull it down any further. Basic P=VT from high school.
Not so mysterious now... Don't open the high side to the gauges unless the system is empty and you are pulling a vacuum. Wear gloves and goggles just in case.

You should charge the system with nitrogen to the top pressure the system is made and make sure it holds that pressure for at least an hour before adding new refrigerant to the system.
