The 1st one is that the refrigerant should be drained by an aircon specialist!!
After that its simple enough, just unplug the electrics, take the belt off and unbolt/disconnect as you see fit!
Within the electrics you will see a wire that goes to a sensor on the top fron of the engine, leave this in place, as it is a backup for overheating! When the engine rises to a set temp (between half and 3 quarters on mine) the aircon fans kick in automatically!
