    Split system charging

    I have a couple questions about charging split residential systems. If all the refrigerent is recovered and the compressor is off can you charge from both high and low sides? Once you turn on the system to add more charge which side is best to charge from, liquid or vapor side? If the system is running can you just flip the bottle and add charge to the liquid side until you hit your mark? or is it best to charge slowly through the vapor side? Also do these methods change between r-22 and 410-A?
