Product/Design Overview (D3)

The third chapter of this manual (D3) is more practically oriented than the previous chapters. It is geared toward identifying problems and issues routinely encountered in the field and offers guidance and/or recommendations for resolving them with minimal effort. This section offers the most value if read early in a project as many of the recommendations impact design or installation philosophies that once set, can be difficult to modify. It is recommended reading for any group involved in locating, supporting or installing mechanical systems in structures.

10 Biggest Seismic Problems Dealt with by Contractors (D3.1)
This document identifies 10 items that routinely cause problems for installation contractors. Included are identification of the problems as well as alternate less costly designs and possible solutions if the problems are unavoidable.

Cables vs Struts for Ceiling Mounted Pipe/Duct/Conduit Restraint (D3.2)
This is a cautionary document intended only as a warning that Cable and Strut restraint systems behave very differently and different rules must be applied. More detail is available in the Piping, Duct and Conduit sections of the manual.

When to Use Combination Isolator/Restraints (D3.3)
Benefits of using combination Isolator/Restraint components and common applications are addressed here from a design standpoint.

When to Use Separate Isolator/Restraints (D3.4)
Benefits of using separate Isolator/Restraint components and common applications are reviewed from a design standpoint.

High Capacity Restraint Configurations (D3.5)
As the codes have changed and required restraint capacities have increased, older more conventional restraint designs have been found to be insufficient for many applications. This section is an overview of the issues faced when selecting restraints for the more severe applications found today and what avenues are open to optimize the installation.

Hybrid Isolator/Restraints (FMS) (D3.6)
In an effort to provide a more suitable restraint system better tailored to current requirements, Kinetics Noise Control has developed the FMS family of Isolator/Restraints. These components can be mixed and matched to provide a broad range of capacities. In addition, they can be used either as separate restraints or in combined isolator/restraint applications. This section addresses the uses and benefits of the FMS components for many potential applications.

Roof Mounted Equipment Applications (D3.7)
Roof mounted equipment applications have always involved challenges not experienced with indoor applications. These range from wind and weather considerations to variations in structural attachment. Because new code requirements have greatly increased the design force levels at the roof, the design for these applications has become more complicated. This section offers an overview of what is involved.
