** NOTE TO SPECIFIER ** Select one operation method below; delete others. Revise to suit specific requirements.
 
4.
Operation Method: Hand operation with push bars.
5.
Operation Method: Crank operation with removable-crank operator in sill or jamb.
6.
Operation Method: Motor operation, with two-position, spring-return application (with power on, motor opens louver; with power off, spring closes louver); 110-V, 50/60-Hz motor; and limit switch wired for grounding; equipped as follows:
 
** NOTE TO SPECIFIER ** Subparagraph below is an example of pneumatic operators available from one louver manufacturer. Coordinate with Mechanical Engineer and with manufacturers selected.
 
7.
Operation Method: Pneumatic piston operation for use with 80- to 100-psi (550- to 690-kPa) compressed air.
 
** NOTE TO SPECIFIER ** If retaining subparagraph above, select one of four subparagraphs below.
 
a.
Operation: Two position; power open, power close.

A.
Prepare substrates and openings using methods recommended by manufacturer for achieving best result for substrates under project conditions.
B.
Do not proceed with installation until substrates and nailers have been prepared using the methods recommended by the manufacturer and deviations from manufacturer's recommended tolerances are corrected. Commencement of installation constitutes acceptance of conditions.
C.
If preparation is the responsibility of another installer, notify Architect in writing of deviations from manufacturer's recommended installation tolerances and conditions.
3.2
INSTALLATION
A.
Install in accordance with manufacturer's instructions.
1.
Locate and place units level, plumb, and at indicated alignment with adjacent work.
2.
Use concealed anchorages where possible. Provide brass or lead washers fitted to screws where required to protect metal surfaces and to make a weathertight connection.
3.
Form closely fitted joints with exposed connections accurately located and secured.
4.
Provide perimeter reveals and openings of uniform width for sealants and joint fillers as indicated on Drawings.
5.
Repair finishes damaged by cutting, welding, soldering, and grinding. Restore finishes so no evidence remains of corrective work. Return items that cannot be refinished in the field to the factory, make required alterations, and refinish entire unit or provide new units.
6.
Protect galvanized and nonferrous-metal surfaces from corrosion or galvanic action by applying a heavy coating of bituminous paint on surfaces that will be in contact with concrete, masonry, or dissimilar metals.
 
** NOTE TO SPECIFIER ** Verify that Section title listed below is correct for this Project's Specifications because Section title may have changed since this Section was updated.
 
B.
Install concealed gaskets, flashings, joint fillers, and insulation, as installation progresses, where weathertight joints are required. Comply with Division 7 Section "Joint Sealants" for sealants applied during installation.
3.3
ADJUSTING, CLEANING AND PROTECTION
 
** NOTE TO SPECIFIER ** Paragraph below applies only to louvers, delete if only specifying grilles.
