Meeting IBC Seismic Requirements
Daikin unit ventilators can be specified, as follows, to meet International
Building Code seismic requirements:
•
All components included in these unit ventilators are designed,
manufactured and independently tested, rated and certified to meet
the seismic compliance standards of the International Building
Code.
•
Components designated for use in systems that are life safety,
toxic, high hazard, combustible or flammable meet the on line,
anchorage and load path requirements for life safety as defined in
IBC sections 1621.1.6, 1621.3.3,1707.7.2. and IBC Commentary,
Volume II, section 1621.1.6, IBC notes pertaining to the release of
hazardous material.
•
All components used as part of a system other than the above meet
as a minimum, all load path and anchorage standards for components
as outlined in IBC section 1621.3.3 & 1707.7.2.
•
All completed component assemblies are clearly labeled for field
inspection. Seismic Compliance Labels include the manufacturer’s
identification, designation of certified models, definitive information
describing the product’s compliance characteristics, and the
Independent Certifying Agency’s name and report identification.
In addition to all seismic requirements for IBC Certification listed
elsewhere in the project specification, submittals for these units
include:
1.
A Certificate of Compliance from the Independent Certifying
Agency clearly indicating that components supplied on this
project are included in the component manufacturer’s Certificate
of Compliance.
2.
Clear installation instructions including all accessory components
that are part of the overall component installation.
