L7 <br />0 <br />r <br />Join frame members to one another and to stationary louver <br />blades by welding, except where indicated otherwise or where <br />field bolted connections between frame members are made <br />necessary by size of louvers. Maintain equal blade spacing, <br />r including separation between blades and frames at head and <br />sill, to produce uniform appearance. <br />STATIONARY EXTRUDEDALUMI WALL LQWERS : <br />Horizontal Drainable Blade Lovers; Dual drain recessed <br />mullion type. Units designed to collect and drain water to <br />exterior at sill by means of gutters in front edges of <br />blades, and channels in jambs and mullions. Furnish units <br />with extrusions not less than 0.08111 thick, of depth, and <br />sizes indicated, equal to AIROLITE Models K611 and T608. <br />Free Area: Not less than 50% for a 4811 x 4811 size. <br />Static Pressure Loss: Not more than 0.1511 of water gage <br />at an airflow of 1050 fpm free area velocity in intake <br />direction. <br />Water Penetration: Not more than 0.05 oz. per sq. ft. of <br />free area at an airflow of 1000 fpm free area velocity. <br />AMCA Certification: Furnish units bearing AMCA Certified <br />Ratings Seal. <br />continuous Horizontal Blades: Conceal supporting <br />framework from vision on outside face of louver by <br />placing braces, mullions and brackets on inside face; <br />with close fitting, field -made splice joints in blades <br />sdesigoed to permit expansion and contraction without <br />deforming blades or framework. <br />LOUVER SCREENS <br />Provide removable bird and insect screens for exterior <br />louvers. <br />Fabricate extruded aluminum screen frames of same finish as <br />louver units to which secured. <br />Use bird screens made of 1/211 sq. mesh, 0.06311 aluminum wire, <br />and insect -screens Of yxey fAsJ-_.E las€i screening in an <br />aluminum frame. <br />Locate screens can inside face of louvers. Secure screens to <br />louver frames with machine screws, spaced at each corner and <br />at 1211 o.c. between. - <br />METAL FINISHES: <br />General; Comply with NAAMM "Metal Finishes Manual" for finish <br />designations and application recommendations, except <br />as otherwise indicated. Apply finishes in factory after <br />products are assembled. Protect finishes on exposed surfaces <br />with protective covering, prior to shipment.
