ELASTOMERIC ISOLATOR INSTALLATION
Read the following instructions before beginning
installation.
1. Isolators are shipped fully assembled and are to be
positioned in accordance with the submittal draw-
ings or as otherwise recommended.

on a level surface. Shim or grout as required,
leveling all isolator bases to the same elevation
(0.03125 of an inch maximum difference can be
tolerated).
3. Bolt or anchor all isolators to supporting structure
utilizing base thru holes (B).
4. Remove top bolt and top washer. Place equip-
ment on top of isolators so that mounting holes in
