Dumb AC question

[gold10go4]

I want to evacuate my AC unit on the 2000 S10 I have. I want to save the freon in a recovery cylinder. I have a vacuum pump with the inlet port mounted in an obvious fashion.

I don't see an outlet port, other than what appears to be a blow-by type port which doesn't have any fittings which could be hooked up to a recovery tank.

How do you use the vacuum pump to allow for freon recovery?
