#1 Venting the refrigerant from your system is a federal crime (a
violation of the clear air act) . Even if you don't care about the
environment it probably isn't the best idea to admit to a federal
crime on a world wide public newsgroup.


While you are trying to charge is the compressor turning? The
refrigerant carries the oil through the system. If the refrigerant
gets low the oil isn't distributed and the compressor dies. To
prevent this from happening the manufacturer puts a low pressure drop
out switch on the system that turns off the compressor under low
pressure situations.

Check to make sure the compressor is energized ( the front disk
spinning as well as the pulley). If it isn't energized locate the low
pressure switch and jump it out so the compressor will spin then
charge the system. If it still won't take more than half a can you
need to check the high and low side pressures and get back to us.

In all honesty you are probably in over your head on this one. After
venting the system the dryer really should be replaced and the system
vacuumed. Your also dealing with a $400 compressor that you can
easily ruin by adding an improper amount of refrigerant or oil.

Good luck. I hope that couch is comfortable ;-)
