Note: Please reference EFCO's "Understanding Condensation" brochure which can be obtained through your EFCO
representative.
Condensation will form on any surface when unfavorable conditions (interior temperature and relative
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 possible installation methods. Please contact your EFCO representative for information on EFCO's Thermal
Analysis Services.
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 likel y to occur:
1. Bridging system thermal break with non-thermally bro ken metal fla shing 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
Minimizing Condensation
Note: These installation instructions are a supplement to the approved shop drawings
and are to be used in conjunction with those drawings.

E-Lite Fabrication, Assembly and Installation Instructions
Section I: General Notes and Guidelines
A. HANDLING / STORING / PROTECTING ALUMINUM - The following
precautions are recommended to assure early acceptance of your products and
workmanship.
1. HANDLE CAREFULLY- Store with adequate separation between
components so the material will not rub together. Store material off the
ground. Protect materials against weather elements and other construction
trades.
2. KEEP MATERIAL AWAY FROM WATER, MUD, AND SPRAY - Prevent
cement, plaster, and other materials from contacting and damaging the
finish. Do not allow moisture to be trapped between the finished surface and
the wrapping material.
3. PROTECT MATERIALS AFTER ERECTION - Wrap or erect screens of
plastic sheeting over material. Cement, plaster, terrazzo, and other alkaline
materials are very harmful to the finish and are to be removed with soap and
water before hardening. Under no circumstances should these materials be
allowed to dry or permanent staining will occur.
B. GENERAL GUIDELINES - The following practices are recommended for all
installations:
1. REVIEW APPROVED SHOP DRAWINGS – Become thoroughly familiar
with the project. Shop drawings govern when conflicting information exists in
these installation instructions.
2. INSTALL ALL FRAMING MATERIAL PLUMB, LEVEL, AND TRUE –
Proper alignment and relationships to benchmarks and column centerlines, as
established by the architectural drawings and the general contractor, must be
maintained.
3. THE SEQUENCE OF ERECTION SHOULD BE COORDINATED WITH THE
PROJECT SUPERINTENDENT TO PREVENT DELAYS AND MINIMIZE THE RISK
OF MATERIAL DAMAGE. NOTE: IF ADDITIONAL ANCHORS ARE
REQUIRED, COORDINATE AND SUPERVISE ANCHOR PLACEMENT
WITH THE GENERAL CONTRACTOR.
4. Verify that all job site conditions and accompanying substrates receiving the
installation are in accordance with the contract documents. If deviations
occur, notification must be given IN WRITING to the general contractor and
differences resolved before proceeding further with the installation in the
questionable area.

Section I: General Notes and Guidelines
5. Prevent all aluminum from coming in direct contact with masonry or dissimilar
materials by means of an appropriate primer.
6. Follow EFCO framing installation instructions.
Verify contents of all material shipments received upon their arrival. Verify quantity
and correct finishes. NOTIFY EFCO IMMEDIATELY OF ANY DISCREPANCIES OR
DAMAGE, WHICH MAY HAVE OCCURRED
Basic Design Guidelines
E–Lite is to be used for maximizing daylight potential in Southern Exposed Glazed Framing
Products.
E-Lite should be located at a height above the floor that does not interrupt flow of foot
traffic.
E-Lite projection must not exceed 36” from the mounting wall product or substrate.
E-Lite nonexposed internal structural components are typically mill finish; however, they
may be painted or anodized per preference. Aluminum panels will be painted as specified.
It is suggested that a nonspecular light colored finish be used for the upper surface of the
shelf to maximize the reflection of daylight into the space.
[It is advised that local building and fire code officials be consulted for applications with E Lite and fire sprinkler systems.]
E-Lite is designed to be a self supporting sun control device. It is not intended to be used
for storage of potted plants, books, etc. Do not place any objects on the E - Lite System or
use as a support handle or step.
[Additional loads (potted plants, books, etc.) may be possible to accommodate on a per
project basis.]
E-Lite System is designed as an accessory for EFCO Corporation Curtain Wall and
Storefront Products. Contact your local representative for product specific attachment
details.
E-Lite System CANNOT be installed on any INSIDE GLAZED Curtain Wall or Storefront
horizontals. Contact your local representative for specific product details.
E-Lite System MUST NOT
“bridge” any expansion joint or expansion mullion.

Section III: E-Lite “Stick Built” Internal Support Channel Assembly
1. Fabricate and Install Internal Support Channel.
A.) The internal support channel must be cut to length (nominally 4” less than strut centerline to centerline dimension).
Locate and drill all attachment holes in the support channel. (Typically the same anchor screw is used at the
internal channel support as used to anchor the channel base.)

#13D8
B.) Align drill a clear hole in the channel base and a pilot hole in the horizontal mullion. (This is recommended even if
self drilling screws are used to avoid binding or breaking of the screw.)
C.) Install internal support channel equally spaced between the support struts. Tighten attachment screws firmly.
