INSTALLATION INSTRUCTIONS
1. Read instructions in their entirety before begin-
ning installation.
2. Isolators are shipped fully assembled and are to be
positioned in accordance with the submittal draw-
ings or as otherwise recommended.
3.
Set isolators on floor, housekeeping pad or sub
-
base, ensuring that all isolator centerlines match
the equipment mounting holes. The VMC group
recommends that the isolator base (“B

stalled on a level surface. Shim or grout as re-
quired, leveling all isolator bases to the same
elevation (1/4-inch maximum difference can be
tolerated).

utilizing base slotted holes (“C
”
).
5. Place equipment on top of isolators making sure
that mounting holes of the equipment line up with
isolator positioning pin (“H
”
).
6. The adjustment process can only begin after the
equipment or machine is at its full operating
weight.
7. Adjust each isolator in sequence by turning spring
adjusting bolt (“D
”
) one full counterclockwise
turn at a time. Repeat this procedure on all isola-
tors, one at a time.
8. Continue adjusting each isolator until a minimum
of 1/4" clearance is achieved between the lower
housing and upper housing.
