Figure A-8 Seismic duct connection considerations
All ducted units, either rigidly mounted or mounted on vibration isolators, shall be attached to the ducting
system using flexible duct designed for seismic movement. Flexible loops shall be capable of movement in
the ±X, ±Y, and ±Z planes and must completely isolate the equipment from the duct work. Refer to Liebert
installation instructions for ducting requirements. Follow manufacturer’s installation instructions for proper
seismic application of flexible ducts.
