VAV Box Number VAV - 1, 2, 3...
Fan Coil Unit Number FCU - 1, 2, 3...
Energy Recovery Ventilator ERV - 1, 2, 3...
Identify similar services with different temperatures or pressures. Where pressures could exceed 860 kilopascal, include the maximum system pressure in the label. Label and arrow piping in accordance with the following:
a. Each point of entry and exit of pipe passing through walls.
b. Each change in direction, i.e., elbows, tees.
c. In congested or hidden areas and at all access panels at each point required to clarify service or indicated hazard.
d. In long straight runs, locate labels at distances within eyesight of each other not to exceed 22 meter. All labels shall be visible and legible from the primary service and operating area.
For Bare or Insulated Pipes for Outside Diameters of Lettering
13 thru 35 mm 13 mm
40 thru 50 mm 20 mm
65 mm and larger 20 mm
1.3 SUBMITTALS
Government approval is required for submittals with a "G" designation;
submittals not having a "G" designation are for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government. Submit the following in accordance with Section 01 33 00 SUBMITTAL PROCEDURES:

1.4 QUALITY ASSURANCE
Except as otherwise specified, approval of materials and equipment is based on manufacturer's published data.
a. Where materials and equipment are specified to conform to the standards of the Underwriters Laboratories, the label of or listing with reexamination in UL Bld Mat Dir , and UL 6 is acceptable as sufficient evidence that the items conform to Underwriters Laboratories requirements. In lieu of such label or listing, submit a written certificate from any nationally recognized testing agency, SECTION 23 00 00 Page 10 adequately equipped and competent to perform such services, stating that the items have been tested and that the units conform to the specified requirements. Outline methods of testing used by the specified agencies.
b. Where materials or equipment are specified to be constructed or tested, or both, in accordance with the standards of the ASTM International (ASTM), the ASME International (ASME), or other standards, a manufacturer's certificate of compliance of each item is acceptable as proof of compliance.
c. Conformance to such agency requirements does not relieve the item from compliance with other requirements of these specifications.
1.4.1 Prevention of Corrosion
Protect metallic materials against corrosion. Manufacturer shall provide rust-inhibiting treatment and standard finish for the equipment enclosures. Do not use aluminum in contact with earth, and where connected to dissimilar metal. Protect aluminum by approved fittings, barrier material, or treatment. Ferrous parts such as anchors, bolts, braces, boxes, bodies, clamps, fittings, guards, nuts, pins, rods, shims, thimbles, washers, and miscellaneous parts not of corrosion-resistant steel or nonferrous materials shall be hot-dip galvanized in accordance with ASTM A123/A123M for exterior locations and cadmium-plated in conformance with ASTM B766 for interior locations.
