Series 8700 / 8800 Unitized Curtain Wall Installation Instructions
1. Dynamic starter sills are used with installations that require provisions for vertical movements at the beginning floor of the curtain wall.
2. Units are typically installed from left to right as seen from the exterior of the building. Install each frame unit in sequence, starting at the left jamb unit.
3. Units are lifted by the splice bars attached at the head of each unit. These bars are also used to align the units when stacked vertically.
4. Ensure the HC07 caulk backer has been inserted into the sill as shown in Figures 62 and 64 on page 31. Note that jamb units will receive HC07 on both
ends of the sill. Subsequent units will require HC07 on the right end only of the unit sill as viewed from the exterior.
5. Place a temporary 9/16” shim between the unit sill and the back of the gutter at the dynamic starter sill. The shims are used to maintain the correct spacing
at the stack joint area of the starter sill. See Figures 78 and 79.
6. Lower the jamb unit down into position while inserting the anchor bar (FM03 or FM04) and stacking the unit onto the starter sill. The hook anchors should
also be hooked onto the slab anchors. The unit should now be setting hard on the shims. See Figures 79 and 80.
7. Place a shim pack between the jamb mullion and the condition to prevent the jamb unit from shifting when setting adjacent units. See Figures 78 and 79.
