They should be factory charged with enough refrigerant for ~25ft lines. Braze the lines, evac and pressure drop test, then open the valves to the compressor and charge should be good. Can tweak for different length lines etc.
When brazing the lines should be flushed with nitrogen to prevent oxide scaling/flaking. Also nitrogen evac and purge cycle.
Fan speed setting on furnace control board need to be set to match BTU/tonnage of the condenser.
