Part 3 - Execution

3.01    ERECTION

A. Because of the large dimensions involved and the weight and movement of the panels,verify the structural integrity of the header such that the maximum deflection with live and dead loads is limited to be the lesser of L/720 of the span and 1/4”. Structural support for lateral loads (both wind load and eccentric load when the panels are stacked open) must be provided. It is recommended that all building dead loads be applied to the header prior to installing the NanaWall. If so and if a reasonable amount of time has been allowed for the effect of this dead load on the header, then only the building’s live load can be used to meet the above requirements of L/720 or 1/4”. If not, both the dead and live loads need to be considered.

B. Examine surfaces of openings and verify dimensions; verify rough openings are level, plumb, and square, with no unevenness, bowing, or bumps on the floor.

C. Installation of units constitutes acceptance of existing conditions.

3.02    INSTALLATION

A. Install frame in accordance with manufacturer’s recommendations and installation instructions. Properly flash and waterproof around the perimeter of the opening.

B. Installer to provide appropriate anchorage devices and to securely and rigidly fit frame in place, absolutely level, straight, plumb and square. Install frame in proper elevation, plane and location, and in proper alignment with other work.

C. If necessary, provide drain connections from lower track.

D. Install panels, handles and lock set in accordance with manufacturer’s recommendations and installation instructions.

E. If necessary, adjust hardware for proper operation.

F. Finishing: Field finish under Section 09900 - Painting; seal and finish promptly after installation and prior to exposure to weather in accordance with manufacturer recommendations.

G. Accessories: Screens; install in accordance with screen manufacturer’s recommendations and installation instructions.
