10、NOTE: This guide specification covers the requirements for prefabricated underground distribution system for chilled water, low temperature hot water (less than 95 degrees C (200 degrees F) or dual temperature water.Edit this guide specification for project specific requirements by adding, deleting,

11、 or revising text. For bracketed items, choose applicable items(s) or insert appropriate information.Remove information and requirements not required in respective project, whether or not brackets are present.Comments and suggestions on this guide specification are welcome and should be directed to

12、the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet.Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR).*PART 1 GENERAL*NOTE: Provide one or two sump pumps

13、in valve manholes. Units should discharge by buried piping to the nearest storm sewer if possible. Where not economical to discharge to a storm sewer, pumps are to discharge above grade. Plan discharge locations carefully so water will not be discharged over valve manhole tops, sidewalks, etc. Check

14、 available NPSH versus required NPSH for pump selected. Coordinate power requirements with electrical designer and provide tell-tale light above ground to indicate sump pump failure. Drawing will show the following:SECTION 33 61 00 Page 3Provided by IHSNot for ResaleNo reproduction or networking per

THIS CIRCUIT MUST BE “ON“ AT ALL TIMES, OTHERWISE EXTENSIVE DAMAGE WILL OCCUR TO THE UNDERGROUND HEAT DISTRIBUTION SYSTEM AND PREMATURE FAILURE WILL OCC

17、UR“.Where plastic chilled water piping is interconnected with heating system changeover valves, ensure that design includes means to preclude damage to plastic chilled water piping. This can be accomplished either by using changeover valves that ensure tight shut-off or by using enough metal piping

18、on chilled water side of changeover valve to prevent damage to plastic chilled water piping.*1.1 REFERENCES*NOTE: This paragraph is used to list the publications cited in the text of the guide specification.
