NOTE: Please reference EFCO's "Understanding Condensation" brochure which can be obtained through your EFCO representative.
Condensation wil l form on any surface wh en unfavorable con di ti on s (i nt er ior temperature an d re lative humidity and exterior
temperature) are present. When the formation of excessive condensation is a concern, it is highly recommended that a design
professional is utilized to perform an analysis of the shop drawings to recommend the best installation methods. Please contact
EFCO representat i ve for information on EFCO's Thermal Analysis Servi ces.
Many current installation practices lead to an increase in the possibility of the formation of condensation. Though not all
inclusive, the list of examples below illustrates conditions under which condensation is likely to occur:
1. Bridging system thermal break with non-thermally broken metal flashing or lintels that are exposed to the
exterior.
2. System exposure to cold air cavities.
3. Interior relative humidity levels not maintained at recommended levels, see EFCO's "Understanding
Condensation" brochure.
4. Inadequate separation between system and surrounding condition at perimeter.
5. Product combinations during the shop drawing stage that result in bridging thermal breaks of one or all products
involved.

SECTION I - GENERAL NOTES
The "QUICK SET" storefront family is a ribbon window system,
having many advantages over other systems due to the minimum
fabrication and installation steps.
The Quick Set family contains primarily stock length systems with
in-the-field fabrication. Entrance doors are also a designed part of
these systems, utilizing frames that can accommodate many types
of doors and hardware combinations.
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,
gunnable, liquid filler which when dry provides a resilient, flexible air and water seal
between similar and dissimilar materials. Use Dow Corning 795 or equivalent when
silicone sealant is required, and PTI 707 or equivalent when butyl type 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.

STEP 1) GENERAL NOTES
A. Ensure that all tooling is correct before assembly. For each D.L.O. there
should be a deep pocket and a shallow pocket. If only one D.L.O. is required,
both pockets will be deep. The glass will not be able to be loaded with two
shallow pockets. Also, keep all deep pockets on center D.L.O.'s on the same
side of the D.L.O. See Fig. 1 below.

Install anchors into the head. Fasten the opposite vertical member to all horizontal members.
Make sure that butyl type sealant has been applied to that end of the horizontal members.
Wipe off all excess sealant.
To ensure that the unit will assemble correctly, verify that the intermediate verticals and the
fillers are fabricated opposite of each other.
If strap anchors are to be used, slide them into the head before assembling the ladder.
NOTE: For inside glazed systems, install exterior glazing gasket (WC12) prior to assembly.
For outside glazed systems, install interior glazing gasket (WNE0) prior to assembly of units.
