After the system performance test, the Landscape Architect may request up to five (5) percent of the total sprinkler nozzles be substituted at no additional cost. Upon substantial completion the Contractor shall operate the system in the presence of the Owner and Architect. System shall be tested for manual, semi-automatic, and fully automatic operation. 3.12 FINAL APPROVAL

Upon completion of all tests, final approval for the system will be contingent upon Contractor providing signed and approved sprinkler/plumbing/health and electrical permits as may be applicable in the area. 3 13 SYSTEM OPERATION

The Contractor shall schedule instruction and training sessions for the Owner’s representatives for the operation, winterization and reactivation of the system. The Architect and Owner shall be notified of these sessions at least 7 days in advance. 3.14 WINTERIZATION/DEACTIVATION

The Contractor shall be responsible for one winterization and one reactivation after substantial completion. When using compressed air to winterize the system, do so in two short cycles at no more than 80-psi air pressure. Do not allow pipe close to compressor to get hot to the touch.
