EFCO 525 Series - Manual (Page 3)

SECTION I - GENERAL NOTES
DPS 1/2004
PAGE 1
The "Series 525" is a framing system that is designed for impact
resistance of windborne debris. It can be used as a single-span
storefront window wall, a punched opening system, or as a ribbon
window system. The system can be fabricated for both screw
spline and shear block construction.
The Series 525 system contains primarily stock length material
with in-the-field fabrication, or it may be fabricated in the shop for
delivery to the job site. Entrance doors are also an integrated
part of this system, utilizing frame members and hardware
support systems that accommodate doors and door hardware
that will withstand impact from windborne debris.
1.) Check the shop drawings, installation instructions, and glazing instructions to
become thoroughly familiar with the project. The shop drawings take precedence and
include specific details for the project. The installation instructions are of a general
nature and cover the most common conditions encountered.
2.) Check all materials on arrival and be sure you have everything required to begin
installation. See Section II "PARTS IDENTIFICATION" for parts cross reference.
3.) All work should start from bench marks and/or column center lines as established
by the architectural drawings and the general contractor. Installers should check
building construction for compliance with architectural documents to ensure the proper
window system foundation is available before installation.
4.) The term "sealant" as used in these instructions is defined as: A weather resistant,
gunable liquid filler, when dry, provides a resilient, flexible air and water seal between
similar and dissimilar materials. In these instructions Dow Corning 795 or equivalent is
used when silicone sealant is required and PTI 707 or equivalent is used when butyl
type sealant is required. Dow Corning 995 or equivalent structural silicone is used
where glazing sealant is required.
All sealant must be compatible with all surfaces on which adhesion is required,
including other sealant surfaces. All frame surfaces should be clean and dry. All
perimeter substrate shall be cleaned and properly treated to receive sealant.
5.) All materials are to be installed plumb, level, and true.
6.) Protect materials after erection. Cement, plaster, alkaline solutions, and acid based
materials can be harmful to the finish. Clean exposed finished surfaces with a mild
detergent and water. No abrasive cleaning agent should be used.
