Default AC compressor install

Hey everyone

Hoping someone is familiar with AC systems to answer a question. Bought a 2004 Audi A4 1.8T with no working AC. Well, being a complete moron, I recharged the system to proper pressure before realizing that the AC compressor was bypassed by the belt and not in operation. Here is the question:

Will hooking up the compressor now to a previously fully charged AC system damage it? Do I need to evacuate, hook up the AC compressor, THEN charge it - or will I be okay hooking it up as is?

Thanks!

How was it recharged?

The refill can gets sucked in to the system by the compressor cycling itself.

The compressor was probably bypassed with a shorter belt because it was not working..just a guess.
First, make sure the ac pulley is not seized.
