EFCO S5500 Outside Glazed - Manual (Page 27)

EFCO CORPORATION 6/2012 PART NO. Y550
Series 5500 Outside Glazed Installation Instructions
NOTE: The typical glass bite for the captured system is ½”.
Glass sizes are based on D.L.O. plus 1”.
Section V: Glazing Installation
IMPORTANT NOTE: EFCO recommends using conventional tubular spacers
only for insulated glass units with the S-5500. This is due to the possible
collapse of the spacer when used with drive-in wedge glazing gaskets.
STEP #1 INSTALL GLAZING MATERIALS
A. Using suction cups, gently insert a glass edge (or other glazing infill) into the deep pocket
of the vertical mullion.
B. Swing the opposite edge of the glazing in plane with the shallow pocket of the adjacent
vertical mullion, and lower the glazing onto the setting blocks.
C. Position the glazing in the center of the opening maintaining a ½” glass bite around the
entire perimeter.
D. Lift the infill slightly off the setting blocks, and press the glass firmly against the interior
glazing gaskets at the sill horizontal.
STEP #2 INSTALL TEMPORARY RETAINER GASKETS
A. Use 2” long pieces of the exterior wedge gasket to temporarily compress and hold the
glass in the glazing pocket of the verticals. The gaskets should be placed at the corners of
the glazing and then periodically up the vertical. Remove any excess sealant at the cor-
ners of the glazing on the interior side that may ooze out where the gaskets were butt
sealed.
NOTE: Clean all glazing pockets prior to glazing. This is
necessary to avoid clogging the weep system as well as to
prevent staining of the exterior metal and glass surfaces.
