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 WC19, WC20 and WC21 gaskets will be shop crimped in place.
Verify these gaskets have been crimped securely to the frame. WC16 is a push-in type gasket. 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 (WC19, LC23,
WC21 and WC20).
c. The 17D9 stack joint caulk backer is shop applied to the frame. Ensure the 17D9 in intact and properly applied. See Figure 58. The 17D9 will be
shop attached with sealant. Make sure the caulk backer aligns with the notch in the vertical.
d. Mullion plugs are required at the head and sill of the captured system in the ends of the verticals. The mullion plugs will be shop applied and sealed
in place. Check to ensure the mullion plugs have been properly applied.
