NOTES:
2.5   The rods are not symmetric end-to-end and have not been installed in a systematic way.
I (RJM) just realized that that these should have the end with the shorter threads at the non-ITC end.  The nuts should be put on this end first, then pushed into the counter-bored hole and finially the nuts put on the other end and tightened.

NOTES: 1. Measure Tile Slot 1 at the bottom of the slot and Tile Slot 11 at the top

(where the widths are assumed to be minimum)

    1. Required shims make the minimum slot width in the range 4:4.5 mm
    2. Gaps are numbered starting at the ITC end.

NOTE: Tiles are numbered from the beginning of the cell, starting at the tile closest to the ITC end of the module. Count every other profile to count the tiles. Odd tile layers start at the cell boundary (count from the first profile), even tile layers start with a spacer plate (count from the second profile). The tile counting stick makes it easier to locate the tiles.
