Installing the 1 in. deflection spring isolators
Note:
- Read the instructions in their entirety before beginning installation
- Isolators are shipped fully assembled. Make sure the AVM types are correct, as found
on the print codes and adhesive labels, and match each load point with corresponding
isolators
1. Twist off the fixing bolt and washer anti-clockwise.
2. Set the isolators on the floor. Ensure that all isolator centerlines match the equipment
mounting holes. Install the isolator base on a level surface. Level all isolator bases to the
same elevation. A maximum difference of 1/4 in. can be tolerated.
3. Place the equipment on top of the isolators making sure that the mounting holes of the
equipment line up with isolator installation holes.
4. Place the fixing bolt and washer but do not tighten them.
5. Ensure the verticality of the isolators and use bolts to fix the bases of the isolators to the level
floor. Use the same torque to fasten the bolts.
6. Only begin the adjustment process after the unit is at its full operating weight.
7. Measure the height of the housing. Adjust each isolator in sequence by turning adjusting
bolt. Repeat this procedure on all isolators, one at a time.
8. Fine adjust isolators to level the equipment. Fasten the M20 thin nut and fixing bolt.
