1. Locations of all vibration isolation devices shall be selected for ease of inspection and

adjustment as well as for proper operation.

2. Installation of vibration isolation equipment shall be in accordance with the

manufacturer's instructions.

B. Isolators

1. All vibration isolators shall be aligned squarely above or below mounting points of the

supported equipment.

2. Isolators for equipment with bases shall be located on the sides of the bases which are

parallel to the equipment shaft unless this is not possible because of physical constraints.

3. Locate isolators to provide stable support for equipment, without excess rocking.

Consideration shall be given to the location of the center of gravity of the system and the

location and spacing of the isolators. If necessary, a base with suitable footprint shall be

provided to maintain stability of supported equipment, whether or not such a base is

specifically called for herein.

4. If a housekeeping pad is provided, the isolators shall bear on the housekeeping pad and

the isolator base plates shall rest entirely on the pad. Anchors shall be located a

minimum of 6” from the edge of the pad.

5. Hanger rods for vibration-isolated support shall be connected to major structural

members, not the floor slab between major structural members. Provide suitable

intermediate support members as necessary.

6. Vibration isolation hanger elements shall be positioned as high as possible in the hanger

rod assembly, but not in contact with the building structure, and so that the hanger

housing may rotate a full 360° about the rod axis without contacting any object.

7. Parallel running pipes may be hung together on a trapeze that is isolated from the

building. Isolator deflections must be the greatest required by the provisions for pipe

isolation for any single pipe on the trapeze. Do not mix isolated and unisolated pipes on

the same trapeze.

8. Pipes, ducts and equipment shall not be supported from other pipes, ducts and equipment.

9. Resiliently isolated pipes, ducts and equipment shall not come in rigid contact with the

building construction or rigidly supported equipment.

travel limit nuts and travel limit brackets.

11. Adjust all leveling bolts and hanger rod bolts so that the isolated equipment is level and

in proper alignment with connecting ducts or pipes.

C. Bases

1. No equipment unit shall bear directly on vibration isolators unless its own frame is

suitably rigid to span between isolators and such direct support is approved by the

equipment manufacturer. This provision shall apply whether or not a base frame is called

for on the schedule. In the case that a base frame is required for the unit because of the

equipment manufacturer's requirements and is not specifically called for on the

equipment schedule, a base frame recommended by the equipment manufacturer shall be

provided at no additional expense.

2. Unless otherwise indicated, there is to be a minimum operating clearance of 1" between

steel rails, steel frame bases or inertia bases and the floor beneath the equipment. The

isolator mounting brackets shall be positioned and the isolators adjusted so that the

required clearance is maintained. The clearance space shall be checked by the Contractor

to ensure that no construction debris has been left to short circuit or restrict the proper

operation of the vibration isolation system.

3. Isolation bases shall be installed in strict accordance with the manufacturer’s instructions.

D. Flexible Duct Connections

1. Prior to installation of the flexible connection, sheet metal ducts and plenum openings

shall be squarely aligned with the fan discharge, fan intake, or adjacent duct section, and

the gap between connected parts shall be uniform. Flexible duct connections shall not be

installed until this provision is met. There shall be no metal-to-metal contact between

connected sections, and the fabric shall not be stretched taut.

E. Flexible Pipe Connections

1. Install flexible pipe connections in strict accordance with the manufacturer's instructions.

2. Where equipment is spring isolated, install flexible pipe connections at all pipe

connections to equipment.

F. Grommets

1. Where grommets are required at hold down bolts of isolators, bolt holes shall be properly

sized to allow for grommets. The hold down bolt assembly shall include washers to

distribute load evenly over the grommets. Bolts and washers shall be galvanized.

G. Resilient Penetration Sleeve/Seals

1. Maintain an airtight seal around the penetrating element and prevent rigid contact

between the penetrating element and the building structure. Fit the sleeve tightly to the

building construction and seal airtight on both sides of the construction penetrated with

acoustical sealant.

insulation products. ECOSE Technology reduces our binder embodied energy by up to 70% and

does not contain phenol, formaldehyde, acrylics or artificial colors.

O. The UL Environment / GREENGUARD Certification Program (formerly known as

GREENGUARD Indoor Air Quality Certification) gives assurance that products designed for

use in indoor spaces meet strict chemical emissions limits, which contribute to the creation of

healthier interiors. Achieving UL Environment / GREENGUARD Certification gives credence

to manufacturers’ sustainability claims, backing them with empirical scientific data from an

unbiased, third-party organization.

P. UL Environment / GREENGUARD GOLD Certification: (Formerly known as GREENGUARD

CHILDREN & SCHOOLS Certification) offers stricter certification criteria, considers safety

factors to account for sensitive individuals (such as children and the elderly), and ensures that a

product is acceptable for use in environments such as schools and healthcare facilities. It is

referenced by both The Collaborative for High Performance Schools (CHPS) and the

Leadership in Energy and Environmental Design (LEED) Building Rating Systems.

Q. UL Environment / GREENGUARD Formaldehyde Free Verification Requirements: for a

product to be verified as formaldehyde free, product samples must have a measured emission

factor of less than or equal to 5 µg/m2 h at 24 elapsed hours or 3 µg/m2 h at 336 elapsed hours.

An emission factor of 5 µg/m2 h, corresponds to a chamber concentration of 2.5 µg/m3 for a

typical building ratio of 0.5 m2/m3.This chamber concentration is comparable to, or below

typical outdoor air concentrations. This demonstrates that the formaldehyde exposure from

products labeled as formaldehyde free will not contribute to airborne formaldehyde

concentrations at greater levels than those found in the natural outdoor environment.

R. Underwriter’s Laboratories Environment (UL Environment / GREENGUARD): offers

independent green claims validation, product assessment and certification. UL Environment /

GREENGUARD provides third-party credibility for sustainable products.

S. EUCEB: exonerated fiber from a health and safety standpoint by the European Certification

Board process.

T. Recycled content – post-consumer: materials such as bottled glass collected at curbside or other

collection sites after consumer use and used in the manufacturing process to create a new

product rather than being placed in a landfill or incinerated.

U. Recycled content – pre-consumer (aka post-industrial): materials used or created from one

manufacturing process which are collect-ed as scrap and placed back into another

manufacturing process rather than being placed in a landfill or incinerated.

V. Polybrominated diphenyl ethers (PBDE) such as Penta-BDE, Oc-ta-BDE or Deca-BDE fire

retardants: have been linked to adverse health effects after exposure in low concentrations.

W. UL Classified: UL has tested and evaluated samples of the product with respect to certain

properties of the product. UL Classifies products to:

1. Applicable UL requirements

2. Standards for safety

3. Standards of other National and International organizations

1.6 DELIVERY, STORAGE, AND HANDLING

A. Packaging: Insulation material containers shall be marked by manufacturer with appropriate

ASTM standard designation, type and grade, and maximum use temperature.

1.7 COORDINATION

exiting the well field along with the building winter supply temperature). The circuits to the

well field should be manually opened (individually) and slowly to prevent the geothermal sup-

ply temperature from being less than the internal, building dew point temperature (to prevent

sweating during initial building system startup, when building still has high internal dewpoint).

B. During initial system startup, with building at minimal internal load and well field at initial use,

the capacity of the well field can produce geothermal supply temperatures less than the building

dewpoint. Caution should be utilized during initial system startup.
