60 psi sounds close to me to there is only the low pressure side that is measured. Most recharge kits come with basic instructions and so do Haynes/Chiltons books..

Get a real set of manifold gauges.

Trying to charge an AC system accurately with only a low-side gauge is like trying to watch a 3-D movie with only one eye.

You really need a set of guages so you can check hi side as well. But about some where between 35-45 low side and around 250-300 high side will be nice and cold

Take it to a pro - it doesn't cost that much and you know it will be done right.

There are to many variables possible for that statement to cover all possibilities.
