6. Verify that framing system is appropriately sized for IGU thickness and that precautions are taken to not over compress the edge seals of the IGU when the glass is installed.

B. Do not proceed with glazing until unsatisfactory conditions have been corrected.

3.2 PREPARATION

A. Surface Preparation:

1. Clean and prepare glazing channels and other framing members to receive glass and wire.

2. Remove coatings and other harmful materials that will prevent glass and glazing installation required to comply with performance criteria specified.

3. Install grommets at all locations where Frame Cable will penetrate metal framing or structure.

3.3 INSTALLATION

A. Install products using recommendations of manufacturers of glass, sealants, gaskets, and other glazing materials, except where more stringent requirements are indicated, including those in the "GANA Glazing

Manual".

B. Verify that IGU secondary seal is compatible with glazing sealants.

C. Install glass in prepared glazing channels and other framing members.

D. Install glass per framing manufacturer’s wiring diagram showing IGU orientation and wire exit point into building. Comply with glass manufacturer’s labels and instructions for glass orientation.

E. Protect IGU pigtail and Frame Cable from any damage during installation. Use grommets during installation to protect wire when routing through frame. If Frame Cable or the connector is damaged during installation the Frame Cable must be replaced. If the IGU pigtail connector is damaged during installation manufacturer must be notified and the connector must be repaired with a manufacturer approved method.

F. PVC jacketed plenum cables (Bus, IGU Pigtails, 12 Conductor Cable, Frame Cables, Sensor Cables) should be conditioned for 24 hours at room temperature prior to installation and never installed below 0°C (32° F) ambient temperature. Once installed these wires must not be exposed to sunlight even through glass. If they are installed in an exposed location they must be covered or painted (latex / water based paint only).

G. Verify glazing pocket where IGU Pigtail and Frame Cable connection is made is a dry location.

H. Install silicone setting blocks in rabbets as recommended by referenced glazing standards in GANA Glazing

Manual and IGMA Glazing Guidelines and manufacturer’s Glazing Guidelines.

I. Use silicone edge blocks for all installed panes to prevent glass from walking post installation.

J. Provide bite on glass, minimum edge and face clearances, and glazing material tolerances recommended by

GANA Glazing Manual and as approved by glass manufacturer.

Setting and edge blocks must be made from silicone.

The use of setting blocks made from other materials than as approved by manufacture is not permitted, as material has been known to alter the chemical makeup of plastics and rubbers they come in contact with, resulting in seal failure.

N. Protect glass from edge damage during handling and installation.

O. Install per IGMA North American Glazing Guidelines for Sealed Insulated Glass Units, for Commercial and

Residential Use TM-3000-90(04) states “For dry glazed systems, an adequate seal should consist of a minimum of 0.70 N/mm (4 lb/in) and not exceeding 1.75 N/mm (10 lb/in) applied to the edges of the insulated glass unit by gaskets or other fastening systems.”

P. Prevent glass from contact with contaminating substances that result from construction operations, such as weld spatter, fireproofing, or plaster.

3.4 ADJUSTING

A. Remove glass that is broken, chipped, cracked, or damaged in any way, and replace with new materials.

Damaged glass is glass with edge damage or other imperfections that, when installed, could weaken glass and impair performance and appearance.

3.5 CLEANING

A. Clean glass inside and outside, immediately after installation and sealants have cured, per manufacturer

Electrochromics’ written recommendations.

B. Remove labels and markings from glass.

C. Clean glass per:

1. GANA Glass Informational Bulletin GANA 01-0300 - Proper Procedures for Cleaning Architectural

Glass Products.

D. Do not use scrapers or other metal tools to clean glass.

3.6 TESTING

A. Do not use ‘high voltage spark’ gas analyzers such as Sparklike’s Gasglass on this product. Film and controls damage may occur and potentially void the warranty.
