3.1 PREPARATION

Preparation, unless otherwise specified or approved, must conform to applicable recommendations in the GANA Glazing Manual , GANA Sealant Manual , IGMA TB-3001 , IGMA TM-3000 , and manufacturer's recommendations. Verify wiring is in place for connection. Determine the sizes to provide the required edge clearances by measuring the actual opening to receive the glass. Leave labels in place until the installation is approved, except remove applied labels on insulating glass units as soon as glass is installed. Securely fix movable items or keep in a closed and locked position until glazing compound has thoroughly set.

3.2 GLASS SETTING

Shop glaze or field glaze items to be glazed using glass of the quality and thickness specified or indicated. Glazing, unless otherwise specified or approved, must conform to applicable recommendations in the GANA Glazing Manual , GANA Sealant Manual , IGMA TB-3001 , IGMA TM-3000 , and manufacturer's recommendations. Aluminum windows, may be glazed in conformance with one of the glazing methods described in the standards under which they are produced, except that face puttying with no bedding will not be permitted. Handle and install glazing materials in accordance with manufacturer's instructions. Use beads or stops which are furnished with items to be glazed to secure the glass in place. Verify products are properly installed, connected, and adjusted.

a. Use grommets during installation to protect wire when routing IGU pigtail through frame.

b. If IGU pigtail connector is damaged during installation, notify manufacturer and repair connector using manufacturer's approved method.

3.2.1 Sheet Glass

Cut and set with the visible lines or waves horizontal.

3.2.2 Insulating Glass Units

Do not grind, nip, or cut edges or corners of units after the units have left the factory. Springing, forcing, or twisting of units during setting will not be permitted. Handle units so as not to strike frames or other objects. Installation must conform to applicable recommendations of IGMA TB-3001 and IGMA TM-3000 .

3.3 CLEANING

Clean glass surfaces and remove labels, paint spots, putty, and other defacement as required to prevent staining. Glass must be clean at the time the work is accepted.

3.4 PROTECTION

Protect glass work immediately after installation. Identify glazed

SECTION 08 88 36.02 00 Page 7 openings with suitable warning tapes, cloth or paper flags, attached with non-staining adhesives. Place protective material far enough away from the coated glass to allow air to circulate to reduce heat buildup and moisture accumulation on the glass. Remove and replace glass units which are broken, chipped, cracked, abraded, or otherwise damaged during construction activities with new units.

a. Protection during testing: Comply with the following:

1) Do not use a high-voltage spark gas analyzer such as the

Sparklike Gasglass to evaluate gas content of View Dynamic Glass products.

2) Use of such device may damage film and controls, potentially voiding View Inc. product warranty.

3.5 COMMISSIONING

As part of the work of this section, perform the following:
