C. Time for shutdown of the existing vacuum system shall be coordinated at least 10 work days prior to shutdown with the COR and VA Medical Center.

D. Prior to any work being done, new pipeline shall be checked for particulate or other forms of contamination per NFPA 99.

E. Ensure that the correct type of pipe tubing and fittings are being used.

F. A spot check of the existing pipelines shall be made in the facility to determine the level of cleanness present.

G. The tie-in shall be made as quickly as possible. A nitrogen purge is not required since this would require another opening in the pipe.

H. After the tie-in is made and allowed to cool, slowly bleed the source vacuum back into the pipeline.

Test the work area for leaks with soapy water and repair any leaks.

I. After all leaks, if any, are repaired and the line is fully recharged, perform blow down and testing.

Open the zone that is closest to the main to the system, access the closest outlet to the work, and blow the main through the inlet. After the inlet blows clear into a white cloth, make an additional check at a zone most distant from the work. Perform all required NFPA 99 tests after connection.
