Component Installation Requirements
Seismic Isolation Requirements
Air handling equipment manufactured by Trane is capable of structurally and operationally
withstanding the seismic response criteria as required by the International Building Codes (IBC)
2000,2003, 2006, 2009. Trane has third-party certification for IBC compliance for seismic
applications for unit sizes 3-30. Certification for larger sizes is in process.
Note: If seismic isolation has been specified, the following requirements must be adhered to for
installation. Failure to follow these instruction would void the warranty.
Anchor Requirements
