6. Secure the isolator to the mounting surface using the
base holes in the isolator.
7. After the unit is level, tighten the isolator base mounting
bolts to secure them to the mounting surface.
Leveling the Unit
Before tightening the mounting bolts, level the unit carefully.
Use the unit base rail as a reference. Level the unit to within
1/4 inch over its entire length. Use shims if adjustable isola-
tors (neoprene) are not used.
If adjustable isolators (spring) are used, ensure that the
proper isolator housing clearance is maintained while level-
ing the unit. Isolators are identified by color and/or an isola-
tor part number. Shims under the isolators may be required
if the unit can not be leveled using the isolator leveling bolt.
