22. 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”.
23. 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 110.
24. Rotate the serrated washers where the serrations align with the serrations in the slab anchor and secure the anchor bolts.
25. Tighten the jack bolts of the mullion anchors just tight enough so that the shims at the stack joint below can be removed and the unit stays in the nominal
position. See Figure 103 on page 47. Remove the shims between the sill and the starter sill that were applied in step 16.
