WASH TROUGHS

Material: Fiberglass reinforced polyester resin, 1/4 inch thick, average; inside surface of smooth gel coat finish; outside surface resin sealed with no exposed glass fibers; molded-in color with ultraviolet inhibitor.

Tensile strength (ASTM D 638): 14,000 psi.

Flexural strength (ASTM D 790): 25,000 psi

Flexural modulus (ASTM D 790): 1,000,000 psi.

Color: White.

Construction: Comply with requirements of ANSI/AWWA F101 and ANSI/NSF 61; provide NSF labelled products and proof of certification.

Designed to support applied water loadings at each location.

Designed to resist deflection under full buoyant and gravity water loads with maximum upward and downward deflection less than or equal to L/1000 where L equals the unsupported trough length; maximum deflection at midpoint not greater than 3/16 inch.

Round bottom, vertical sides.

Top edges straight with not more than 1/8 inch deviation from true plane.

Longitudinal steel stiffening ribs integrally molded on the outside of troughs to ensure rigidity.

Plastic spacer rods to maintain uniform width over the length of trough.

2 inch wide, 1/2 inch thick wall, grouting rib molded to outside of each trough at the gullet end to act as a water stop when trough is grouted in place.

Slotted holes in closed end of trough to allow a minimum vertical level adjustment of 1 inch.

Stainless steel wall anchors and flat bars.

Saddle at blind end.

Straight edge weir plates, factory-installed.

PART	EXECUTION

EXAMINATION

Verify that dimensions are correct and project conditions are suitable for installation. Do not proceed with installation until unsatisfactory conditions have been corrected.

INSTALLATION

Install products in accordance with manufacturer's instructions.

Ensure that products are installed plumb and true, free of warp or twist, within tolerances specified by the manufacturer and as indicated in the contract documents.

Set in place with weir edges to elevations indicated.

Level weir edges to within 1/8 inch of level over entire length.

Grout in place after leveling.

ADJUST AND CLEAN

Clean surfaces in accordance with manufacturer's instructions.

Remove trash and debris, and leave the site in a clean condition.
