Unit Isolation and Leveling

For additional reduction of sound and vibration, install
the optional elastomeric isolators.
Construct an isolated concrete pad for the unit or
provide concrete footings at the unit mounting points.
Mount the unit directly to the concrete pads or
footings.
Level the unit using the base rail as a reference. The
unit must be level within 1/4" (6.4 mm) over the entire
length and width. Use shims as necessary to level the
unit.

Elastomeric Isolators

N N o o t t e e : : See unit submittal, or tables in this section, for
point weights, isolator locations and isolator
selections.
1. Secure the isolators to the mounting surface using
the mounting slots in the isolator base plate. Do not
fully tighten the isolator mounting bolts at this time.
2. Align the mounting holes in the base of the unit
with the threaded positioning pins on the top of the

isolators.

3. Lower the unit onto the isolators and secure the
isolator to the unit with a nut.
4. Level the unit carefully. Fully tighten the isolator
mounting bolts.
