PART 3 EXECUTION
3.1 EXAMINATION
A. Examine areas where diffusers, registers, and grilles are to be installed for
compliance with requirements for installation tolerances and other conditions
affecting performance of equipment.
B. Proceed with installation only after unsatisfactory conditions have been
corrected.
3.2 INSTALLATION
A. Install diffusers, registers, and grilles level and plumb.
B. Ceiling/Wall-Mounted Outlets and Inlets: Drawings indicate general
arrangement of ducts, fittings, and accessories. Air outlet and inlet locations
have been indicated to achieve design requirements for air volume, noise
criteria, airflow pattern, throw, and pressure drop. Make final locations where
indicated, as much as practical. For units installed in lay-in ceiling panels,
locate units in the center of panel. Where architectural features or other
items conflict with installation, notify Architect for a determination of final
location.
C. Install diffusers, registers, and grilles with airtight connections to ducts and to
allow service and maintenance of dampers, air extractors, and fire dampers.
