Series 8750XD Unitized Curtain Wall Installation Instructions

1. Before installing the units, follow this checklist to ensure they are ready for installation:

a. Inspect the units to ensure that each unit has all external gaskets and screws. The WA02 and WC21 gaskets will be shop crimped in place.

Verify these gaskets have been crimped securely to the frame. Always check for proper crimping and for missing gaskets.

b. Using an approved solvent or cleaner, clean the vertical and horizontal stack gaskets of all oils and other contaminants ( LC23, LC54,

WC21 and WA02).

c. Mullion plugs are required at the head. Also plugs are required at the head end of the captured system at the end of the Duracast verticals. The

mullion plugs are shop applied and sealed in place. Check to ensure the mullion plugs have been properly applied.

d. All front screw spline screws head should be sealed. See figure 49.
