EXECUTION
3.1
INSTALLATION
Work shall be performed in accordance with the manufacturer's published
diagrams, recommendations, and equipment warranty requirements. The
design, fabrication, and installation of the system shall conform to ASME
BPVC SEC VIII D1 and ASME BPVC SEC IX as applicable. Where applicable,
work shall be performed in accordance with ASHRAE 15 and IIAR 2 for ammonia
systems.
3.1.1
Equipment
**************************************************************************
NOTE: Determine in the initial stages of design the
approximate distances required for maintenance
clearances of all new equipment. The maintenance
clearances will be used in determining the final
layout of the equipment.
**************************************************************************
Equipment shall be properly leveled, aligned, and secured in place in
accordance with manufacturer's instructions. Necessary supports shall be
provided for all equipment, appurtenances, and pipe as required, including
frames or supports for compressors, pumps and similar items. Compressors
shall be isolated from the building structure. Isolators shall be selected
and sized based on load-bearing requirements and the lowest frequency of
vibration to be isolated. Foundation drawings, bolt-setting information,
and foundation bolts shall be furnished prior to concrete foundation
construction for equipment indicated or required to have concrete
foundations. Concrete for foundations shall be as specified in Section
03300A CAST-IN-PLACE STRUCTURAL CONCRETE.
3.1.2
Mechanical Room Ventilation
**************************************************************************
NOTE: For mechanical rooms which are intended to
house refrigeration equipment, designers will use
ASHRAE 15 to determine applicable design criteria.
Delete this paragraph if a mechanical room is not
applicable to the design.
In summary, ASHRAE 15 allows the use of either
natural or mechanical ventilation systems, however
natural ventilation is allowed only in certain
limited applications. Natural ventilation is
allowed only when "a refrigerant system is located
