EXECUTION
3.1
INSTALLATION
3.1.1
Method of Installation
Install in accordance with the window manufacturer's printed instructions
and details. Build in windows as the work progresses or install without
forcing into prepared window openings. Set windows at proper elevation,
location, and reveal; plumb, square, level, and in alignment; and brace,
strut, and stay properly to prevent distortion and misalignment. Protect
ventilators and operating parts against accumulation of dirt and building
materials by keeping ventilators tightly closed and locked to frame. Bed
screws or bolts in sill members, joints at mullions, contacts of windows
with sills, built-in fins, and subframes in mastic sealant of a type
recommended by the window manufacturer. Install windows in a manner that
will prevent entrance of water and wind. Fasten insect screens securely in
place.
3.1.2
Dissimilar Materials
Where aluminum surfaces are in contact with, or fastened to masonry,
concrete, wood, or dissimilar metals, except stainless steel or zinc, the
aluminum surface shall be protected from dissimilar materials as
recommended in the Appendix to AAMA 101. Surfaces in contact with sealants
after installation shall not be coated with any type of protective material.
3.1.3
Anchors and Fastenings
Make provision for securing units to each other, to masonry, and to other
adjoining construction. Windows installed in masonry walls shall have head
and jamb members designed to recess into masonry wall not less than 11 mm
7/16 inch.
3.1.4
Adjustments After Installation
After installation of windows and completion of glazing and field painting,
adjust all ventilators and hardware to operate smoothly and to provide
weathertight sealing when ventilators are closed and locked. Lubricate
hardware and operating parts as necessary. [Adjust double hung windows to
operate with maximum applied force of 25 pounds in either direction, not
including breakaway friction force.]
3.2
CLEANING
Clean interior and exterior surfaces of window units of mortar, plaster,
paint spattering spots, and other foreign matter to present a neat
appearance, to prevent fouling of weathering surfaces and
weather-stripping, and to prevent interference with the operation of
hardware. Replace all stained, discolored, or abraded windows that cannot
be restored to their original condition with new windows.
3.3
SCHEDULE
Some metric measurements in this section are based on mathematical
conversion of inch-pound measurements, and not on metric measurement
commonly agreed to by the manufacturers or other parties. The inch-pound
and metric measurements are as follows:
