PART 3 EXECUTION
3.1 PREPARATION
A. Degrease and clean surfaces to receive adhesive for identification materials.
3.2 INSTALLATION
A. Pipe Labeling:
1. Banding:
a. Apply banding at all connections to equipment, valves, or branch fittings, at wall boundaries and at intervals along the piping not greater than 30 inches on center, with at least one band applied to each exposed run of pipe.
2. Pipe Markers and Directional Arrows:
a. Locate labels at all connections to equipment, valves, or branching fittings, at wall boundaries, and at intervals along the piping not greater than 18 feet on center.
b. Each pipe shall be adequately labeled with a minimum of 2 labels in each room, crawl space or compartment.
c. Locate separate flow directional arrows on each side of pipe marker indicating direction of flow.
d. If flow is bi-directional, use double headed arrows.
B. Equipment Labeling:
1. Install plastic nameplates with corrosive-resistant mechanical fasteners, or adhesive. Apply with sufficient adhesive to ensure permanent adhesion and seal with clear lacquer.
2. Identify air handling units, pumps, heat transfer equipment, tanks, and water treatment devices with plastic nameplates. Small devices, such as in-line pumps, may be identified with tags.
3. Identify ductwork with plastic nameplates. Identify with air handling unit identification number and area served. Locate identification at air handling unit, at each side of penetration of structure or enclosure, and at each obstruction.
