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.
2. Set isolators on floor, housekeeping pad or sub-
base, ensuring that all isolators centerlines match
the equipment mounting holes. The VMC group
recommends that the isolator base ("B") be in-
stalled on a level surface. Shim or grout as re-
quired, leveling all isolator bases to the same
elevation (0.25-inch maximum difference can be
tolerated).
3. Bolt or anchor all isolators to supporting structure
utilizing base slotted holes ("C").
