    5:10 – You say "check your superheat and subcooling levels" to achieve the correct charge.
    I assume this particular HSXA16-036 did NOT recommend using the approach method for charging? If that's true, can you share the tables you used to determine your targets? I can't seem to find them anywhere. Thank you!
