4-6 hours deals with most systems, including those that don't want to empty and/or fill.
It takes 6-8 hours when changing a cylinder that was previously installed by someone who "always" does it in 4 hours.
I shouldn't complain - most of my work involves putting right those things that some idle or incompetent f**ker did wrong in the first place.
