Going to copy exactly what you should do ...
) Refill through the LOW pressure tap under the power steering reservoir.
2) Displace the reservoirs first to make access to the tap easier and reduce the risk of rubbing against the moving belts. Leave the reservoirs attached to their hoses and just lift them up and out of the way.
3) Use a kit with a gauge on it. Fill to between 25 and 45 psi as per the instructions.
Takes five minutes.
Other good info posted right above me .
The high pressure port is the one up front protruding up through the hood striker plate...This port is to be use ONLY when the system is under a vacuum and the engine is NOT RUNNING!!!...Compressor pressures close to 250 pounds exist at this port and could burst the can causing serious injury...In short, this port is for the pros...The insructions for using an electrically heated container, etc. is intended for the pro with the proper equipment...
The low pressure port is down under the power steering reservoir near the serpentine belt...This is where topping-up is done with Walmart/Auto Barn kits...When charging, loosen the hose connection at the gauge a bit and allow a small amout of refrigerant to escape before puncturing the can...This purges the air from the hose which could contain moisture...If moisture gets in, it can form acids that eat up the plumbing, and if there is enough, it can freeze in the expansion valve and stop operation...
= acutally the acids build up and destroy the compressor =
