AC compressors need to be running before the system will pull in refrigerant. Find the pressure switch and jumper the wires with the engine running and the AC turned on, that should engage the AC clutch, pulling in the refrigerant. Keep an eye on the pressure gauge though. Don't overfill or you can destroy the compressor seals.
