Isolation and Sound Emission
The most effective form of isolation is to locate the unit
away from any sound sensitive area. Structurally
transmitted sound can be reduced by elastomeric vibration
eliminators. Spring isolators are not recommended.
Consult an acoustical engineer in critical sound
applications.
For maximum isolation effect, isolate water lines and
electrical conduit. Wall sleeves and rubber isolated piping
hangers can be used to reduce the sound transmitted
through water piping. To reduce the sound transmitted
through electrical conduit, use flexible electrical conduit.
State and local codes on sound emissions should always
be considered. Since the environment in which a sound
source is located affects sound pressure, unit placement
must be carefully evaluated. Sound power levels are
available on request.
Unit Isolation and Leveling
For additional reduction of sound and vibration, install the
optional elastomeric isolators.
AC-SVX003A-EN
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 1/2 inch (12.7 mm) over the entire
length and width. Use shims as necessary to level the unit.
Elastomeric Isolators
Note: 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.
