A/C compressor install

I've installed my new compressor, O-Rings and have my drier ready (have not disturbed the factory dust/seal caps on the drier)

I need to take the car to a shop to complete the job couple of questions

1, At what point do I or the shop connect the drier? Can I fit it if I quickly secure it, or should this be done at the shop?

2, How does the Compressor oil charge work? Do I add it before the gas refill, or do the gas and oil get added at the same time?

Here are your answers:

You add the respective oil amount into the component before you install the component in the car. You would add oil to each component you replace. There should be info on the amount each component takes.

Your compressor probably came with oil in it. You would pour it all out and then add the specific amount based on what was in the old one or a factory chart for correct oil.

You can add your drier as the last component and make sure your system is all buttoned up. They will pull a vacuum first thing to test for leaks, and it boils off the little moisture your system has.

Put it all together yourself and ask them to evacuate, and charge.
