ADA Anchor Installation Notes:
Each pair of ADA(H) all directional anchors provides high frequency noise and vibration isolation for those locations where movement must be controlled.  When the anchors are attached to piping as shown in Illustration 1 below, all expansion will be directed from this point.  Anchors are always used in pairs.

VSG Installation Notes:
Each pair of VSG guides provides high frequency noise and vibration isolation for those locations where movement must be guided in the axial direction.  Guides are always used in pairs.  When pairs of VSG Guides are used as shown in the illustrations bellow right, radial motion is controlled while axial motion is guided.

h104a4.gif (27992 bytes)
Standard VSG Guides can be set to accommodate:
a) 0 Upward Movement and 3-1/4" Downward Movement.
b) 3-1/4" Upward Movement and 0" Downward Movement.
c) 1-5/8" Upward or Downward Movement.
d) Special settings as required and certified.

As Required

Note B If the anchor is next to the joint on one side, no guide is needed on that side.
Note C Guides beyond the anchor may be spaced as in a straight solid run since there is no thrust force.

To more clearly define and control riser load shifts caused by pie expansion and contraction, strategically placed spring supports may be incorporated.  See hanger Bulletin H-610-3w for a detailed description of this method using type SLF Steel Spring Mounts or type HES Pipe Expansion Hangers.
