PART	EXECUTION

PREPARATION

Degrease and clean surfaces to receive adhesive for identification materials.

Prepare surfaces in accordance with Section 09900 for stencil painting.

INSTALLATION

Install plastic nameplates with corrosive-resistant mechanical fasteners, or adhesive. Apply with sufficient adhesive to ensure permanent adhesion and seal with clear lacquer.

Install tags with corrosion resistant chain.

Apply stencil painting in accordance with Section 09900.

Install plastic pipe markers in accordance with manufacturer's instructions.

Install plastic tape pipe markers complete around pipe in accordance with manufacturer's instructions.

Install underground plastic pipe markers 6 to 8 inches (150 to 200 mm) below finished grade, directly above buried pipe.

Identify air handling units, pumps, heat transfer equipment, tanks, and water treatment devices with [plastic nameplates.] [stencil painting.] Small devices, such as in-line pumps, may be identified with tags.

Identify control panels and major control components outside panels with plastic nameplates.

Identify thermostats relating to terminal boxes or valves with nameplates.

Identify valves in main and branch piping with tags.

Identify air terminal units and radiator valves with numbered tags.

Tag automatic controls, instruments, and relays. Key to control schematic.

Identify piping, concealed or exposed, with [plastic pipe markers.] [plastic tape pipe markers.] [stencilled painting.] [Use tags on piping 3/4 inch (20 mm) diameter and smaller.] Identify service, flow direction, and pressure. Install in clear view and align with axis of piping. Locate identification not to exceed 20 feet (6 m) on straight runs including risers and drops, adjacent to each valve and Tee, at each side of penetration of structure or enclosure, and at each obstruction.

Identify ductwork with [plastic nameplates.] [stencilled painting.] 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.

Provide ceiling tacks to locate valves or dampers above T-bar type panel ceilings. Locate in corner of panel closest to equipment.
