4. Open the flow test valve.

5. Drain all water from the preaction system. If the system has operated, or if water has entered the system, allow enough time

to completely drain the system.

6. Close the main drain valve.

7. Open the priming valve. Prime water pressure will enter and expand the valves internal diaphragm assembly onto the valve

seat, effectively closing the valve. Verify prime pressure has been established on the prime pressure gauge.

8. Establish air pressure on the system.

9. Verify that no water flows from the drip check when the plunger is pushed.

10. When the priming pressure has been verified as being established, slowly open the water supply control valve.

11. When flow is developed from the flow test valve, CLOSE the flow test valve.

12. Fully open the water supply main control valve.

13. Secure all valves in their normal operating position.

14. Reset the release control panel.

15. Notify Authorities Having Jurisdiction and those in the affected area that the system is in service.

16. The system is now fully operational.

G. Operational Test:

An operational test shall be performed on the system in accordance with NFPA 13. Refer to Section 6 for Inspection and Operation

Test Procedures.
