Flexible Loops:
All units, either rigidly mounted or mounted on vibration isolators, shall be attached to the piping system using flexible loops 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 piping.
The loops shall be suitable for an operating pressure and temperature of the system, refer to Liebert installation instructions. This includes 1/4"
copper humidifier supply, condensate drainage, and chilled water supply and return. Follow manufacturer's installation instructions for proper
seismic application of flexible loops.
