ONE INCH DEFLECTION ISOLATOR INSTALLATION<br />
1. Read the following instructions before beginning<br />
installation.<br />
2. Isolators are shipped fully assembled and are to be<br />
positioned in accordance with the submittal drawings<br />
or as otherwise recommended.<br />
3. Set isolators on floor, housekeeping pad or subbase,<br />
ensuring that all isolators centerlines match<br />
the equipment mounting holes. The VMC group<br />
recommends that the isolator base (“B”) be installed<br />
on a level surface. Shim or grout as required,<br />
leveling all isolator bases to the same<br />
elevation (0.25-inch maximum difference can be<br />
tolerated).<br />
4. Bolt or anchor all isolators to supporting structure<br />
utilizing base slotted holes (“C”).<br />

5. Place equipment on top of isolators making sure<br />
that mounting holes of the equipment line up with<br />
isolator positioning pin (“H”).<br />
6. Equipment or machine is at its full operating<br />
weight.<br />
7. Adjust each isolator in sequence by turning spring<br />
adjusting bolt (“D”) one full counterclockwise<br />
turn at a time. Repeat this procedure on all isolators,<br />
one at a time.<br />
8. Continue adjusting each isolator until a minimum<br />
of 0.25” clearance is achieved between the lower<br />
housing and upper housing. (See illustration<br />
above).<br />
9. Fine adjust isolators to level equipment.<br />
