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. Johnson Con-
trols recommends that the isolator base ("B")
is installed on a level surface. Shim or grout as
required, leveling all isolator bases to the same
elevation (0.25 in. maximum difference can be
tolerated).
3. Bolt or anchor all isolators to supporting structure
utilizing base slotted holes ("C").
