24. Compare the unit to established bench marks and move the unit side to side to position it laterally to the required location. At the stacked mullions the
mullion width should be 3”.
25. Adjust the starter sill anchor so that it aligns with the vertical. The anchor can be slid from side to side on the insert. Ensure the anchor is pressed against
the back of the starter sill. Rotate the washers at the starter sill anchor so that the serrations align with the serrations in the starter sill anchor.
26. Secure the anchor bolts at the starter sill anchor, locking the anchor in place. See Figure 93
27. Adjust the unit for plumb, parallel to the plane of the wall, by sliding the slab anchor forward or backward until the unit is plumb. See Figure 94.
28. Rotate the serrated washers where the serrations align with the serrations in the slab anchor and secure the anchor bolts.
29. Tighten the jack bolts of the mullion anchors just tight enough so that the shims at the starter sill below can be removed and the unit stays in the nominal
position. See Figure 79 on page 37. Remove the shims between the sill and the starter sill that were applied in step 18.
