I believe Jobo's 1000 ml maximum is to prevent strain on the motor of the rotary units. Your best bet for information is Jobo USA. The folks there do respond promptly to emailed or telephoned technical questions. In the last three months they've been very helpful to me in exorcising a rash of processing demons that suddenly possessed my darkroom (film reticulation, magenta cast on slides, chemistry temperature control).
