Deflectors shall be 1" or as noted on drawings. <br />C. Equipment mounting type schedule: <br />1.Type At Double deflection neoprene mountings shall <br />have a minimum static deflection of 0.35". All ratal <br />surfaces shall be neoprene Tovered to avoid corrosiou <br />and have friction pads both top an 1 bottom so tney need <br />not be bolted to the floor. Bolt holes shall be provided <br />for those areas where bolting is req -.ired. On equipment <br />such as small vent sets and close coupled pumps, steel <br />^v'.ls shall be used above the mountings to compensate <br />tor the overhang, mountings shall be MD or rcHs DNS. <br />Spring isolators shall be free^ianding and laterally <br />without any housing and complete with l''-i" r-toprene <br />acoustical friction pads between the baseplate mo rbe <br />support. All muntings shall have leveling bolts that <br />must be rigidly bolted to the equipment.
