FABRICATION AND OPERATION

Prior to fabrication, verify actual opening dimensions by accurate site measurements. Adjust dimensions for proper fit at openings.

Coordinate with other trades for securing tracks to substrates and other finished surfaces.

Fabricate window treatment components from non-corrosive, non-staining, non-fading materials that are completely compatible and do not require lubrication during normal expected life.

Fabricate blind units to fill openings from head to horizontal mullion and jamb to jamb.

Space slats to provide overlap for light exclusion when fully closed.

Equip horizontal blind units for the following operation:

Full-tilting operation with slats rotating approximately 180 degrees. Place tilt operating controls on left hand side of blind units unless otherwise directed.

Full-height raising, to minimum stacking dimension, with lifting cord locks for stopping blind at any point of ascending or descending travel. Place pull cords on right-hand side of blind units unless otherwise indicated.

PART 3 - EXECUTION

EXAMINATION

FLOOR MATS AND FRAMES 12690 - 4

Examine openings where horizontal louver blinds will be installed prior to beginning installation. Verify that critical dimensions are correct and surface conditions acceptable.

Complete all finishing operations, including painting, before beginning installation.

Do not proceed with installation until unsatisfactory conditions have been corrected.

INSTALLATION

General: Install window treatment units to comply with manufacturer's instructions. Position units level, plumb, secure, and at proper height and location relative to adjoining window units and other related work.

Securely anchor units with clips, brackets, and anchorages suited to type of substrate.

Provide clearance between sash and blinds to permit unencumbered operation of sash hardware.

CLEANING AND PROTECTION

After completing the installation, clean blind surfaces according to the manufacturer's instructions.

Protect installed units to ensure their being in operating condition, without damage, blemishes, or indication of use at substantial completion of project. Correct nonconforming damaged units. Replace units that cannot be field corrected.
