ning installation.
2. Isolators are shipped fully assembled and are to be
positioned in accordance with the submittal draw-
ings or as otherwise recommended.

stalled on a level surface. Shim or grout as re-
quired, leveling all isolator bases to the same
elevation (1/32-inch maximum dierence can be
tolerated).

utilizing base thru holes (“B”).

ment on top of isolators so that mounting holes
