The scroll is now correctly installed with a scroll and trimmed. From experience,
we suggest that you:
i
Run the colour changers end to end a few times. This allows the filter to find

confirm alignment of all units. Retrim where necessary ;
iii
Check the scroll tension at 50% control input; (Mode=E, Addr.=050).
