Pre-Installation Considerations

Meeting IBC Seismic Requirements

Daikin unit ventilators can be specied, as follows, to meet International

Building Code seismic requirements:

• All components included in these unit ventilators are designed,

manufactured and independently tested, rated and certied 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 ammable meet the on line,

anchorage and load path requirements for life safety as dened 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 eld

inspection. Seismic Compliance Labels include the manufacturer’s

identication, designation of certied models, denitive information

describing the product’s compliance characteristics, and the

Independent Certifying Agency’s name and report identication.

In addition to all seismic requirements for IBC Certication listed

elsewhere in the project specication, submittals for these units

include:

1. A Certicate of Compliance from the Independent Certifying

Agency clearly indicating that components supplied on this

project are included in the component manufacturer’s Certicate

of Compliance.

2. Clear installation instructions including all accessory components

that are part of the overall component installation.

threaded rod (by others) - align with unit

mounting holes, and set into building structure

mortar or structural support column (see detail).

(4) - 1-1/2" O.D. x (dimension “X”),

galvanized steel pipe (by others),

gives rigidity to the unit in relation

with the building structure (see detail).

(4) - 3/8" galvanized nut with

washer (by others), attach from

inside unit end compartments.

Tighten nut until steel pipe is

compressed between unit and

building structure or column.
