C. Duct Installation: Install ducts in accordance with approved shop drawings.

1. Install ducts in accordance with SMACNA's "HVAC Duct Construction

Standards - Metal and Flexible" unless otherwise indicated.

2. Install ducts in maximum practical lengths with fewest possible joints.

3. Install factory- or shop-fabricated fittings for changes in direction, size, and shape and for branch connections.

4. Unless otherwise indicated, install ducts vertically and horizontally, and parallel and perpendicular to building lines.

5. Install ducts close to walls, overhead construction, columns, and other structural and permanent enclosure elements of building.

6. Install ducts with a clearance of 1 inch, plus allowance for insulation thickness.

7. Route ducts to avoid passing through transformer vaults and electrical equipment rooms and enclosures.

8. Where ducts pass through non-fire-rated interior partitions and exterior walls and are exposed to view, cover the opening between the partition and duct or duct insulation with sheet metal flanges of same metal thickness as the duct. Overlap openings on four sides by at least 1-1/2 inches.

9. Protect duct interiors from moisture, construction debris and dust, and other foreign materials both before and after installation

237300-5

D. Duct Insulation: Install insulation materials, accessories, and finishes with smooth, straight, and even surfaces; free of voids throughout the length of ducts and fittings.

1. Install insulation materials, vapor barriers or retarders, jackets, and thicknesses required for each item of duct system as specified in insulation system schedules.

2. Install accessories compatible with insulation materials and suitable for the service. Install accessories that do not corrode, compress, or otherwise damage insulation or jacket.

3. Install insulation with longitudinal seams at top and bottom of horizontal runs.

4. Install multiple layers of insulation with longitudinal and end seams staggered.

5. Keep insulation materials dry during application and finishing. Replace insulation materials that get wet during storage or in the installation process.

6. Install insulation with tight longitudinal seams and end joints. Bond seams and joints with adhesive recommended by insulation material manufacturer.

7. Install insulation with least number of joints practical.

8. Apply adhesives, mastics, and sealants at manufacturer's recommended coverage rate and wet and dry film thicknesses.

9. Install insulation with factory-applied jackets as follows:

a. Draw jacket tight and smooth, but not to the extent of creating wrinkles or areas of compression in the insulation.

b. Cover circumferential joints with 3-inch-wide strips, of same material as insulation jacket. Secure strips with adhesive and outward clinching staples along both edges of strip, spaced 4 inches o.c.

c. Overlap jacket longitudinal seams at least 1-1/2 inches. Clean and dry surface to receive self-sealing lap. Staple laps with outward clinching staples along edge at 4 inches o.c.

4. Verify that bearings, pulleys, belts, and other moving parts are lubricated with factory-recommended lubricants.

5. Verify that proper thermal-overload protection is installed for electric coils.

6. Check refrigerant pressures and adjust in accordance with manufacturer’s installation instructions.

7. Install new, clean filters.

3.3 CLEANING

A. After completing system installation and startup tests and checks, of air-handling unit and air-distribution systems, and after completing startup service, clean air-handling units internally to remove foreign material and construction dirt and dust.
