I had a condenser leak (replaced it) so I need to pull a vacuum and add R134 again.

So I don't burn up my compressor what are the correct steps for adding ester oil? (I have a Nippondenso compressor)

Pull a vacuum then add the esther oil via the low side? Do I start the motor or will the vacuum just pull in the oil?

or

Do none of the above and add the oil to a fill port? pior to pulling vaccum?
