Final Acceptance/Commissioning Test: The system will be accepted only after satisfactory test of the entire system has been accomplished by the Contractor at the direction of the C&S Engineers, Inc., in the presence of the Authority Having Jurisdiction and the Owner. The Contractor shall notify the above witnesses, in writing, 72 hours prior to the commencement of testing. Failure to contact the above parties will require the Contractor to conduct tests a second time at the Contractor s expense in the presence of the above parties. C&S Engineers, Inc. shall have complete direction over the final acceptance/commissioning test of the system. C. Water flow detecting devices including the associated alarm circuits shall be flow tested through the inspector s test connection and shall result in an audible alarm on the premises within 5 minutes after such flow begins and until such flow stops. D. The main drain valve shall be opened and remain open until the system pressure stabilizes. Static and residual pressures shall be recorded. E. Tests and Inspections: 1. Leak Test: After installation, charge systems and test for leaks. Repair leaks and retest until no leaks exist. 2. Test and adjust controls and safeties.
