PREACTION SPRINKLER
SYSTEM
3. Close the flow test valve.
4. Trip the system by operating the release system. Allow a full flow to pass through the deluge
valve. Water ow alarms should operate.
5. When test is complete:
a. Close the main water supply control valve.
b. Close the priming valve.
c. Open the auxiliary drain valve.
d. Open all system main drains and auxiliary drains. Allow the system to drain completely.
6. Perform Semi-Annual Maintenance.
7. Place the system in service. Refer to INSTALLATION: PLACING THE VALVE IN SERVICE in the
appropriate deluge valve technical data page.
NOTE: Deluge valves supplied by brackish water, salt water, foam, foam/water solution, or any other cor-
rosive water supply should be flushed with good quality fresh water before being returned to service.
8. Notify the Authority Having Jurisdiction that the test is complete. Record and/or provide notifica-
tion of test results as required by the Authority Having Jurisdiction.
D. Maintenance
Where difficulty in performance is experienced, the valve manufacturer or his authorized representa-
tive shall be contacted if any field adjustment is to be made.
After Each Operation
1. Sprinkler systems that have been subjected to a fire must be returned to service as soon as pos-
sible. The entire system must be inspected for damage, and repaired or replaced as necessary.
2. Deluge valves and trim that have been subjected to brackish water, salt water, foam, foam/water
solution, or any other corrosive water supply should be flushed with good quality fresh water be-
fore being returned to service.
3. Perform SEMI-ANNUAL maintenance after every operation.
Semi-Annual Maintenance for Model E or F Series Deluge Valves
1. Remove the system from service. (Refer to deluge system data that describes systems with the
release system used for additional information.)
a. Close the main water supply control valve and priming valve.
b. Open the auxiliary drain valve.
c. Relieve pressure in the priming chamber by opening the emergency release valve.
2. Inspect all trim for signs of corrosion and/or blockage. Clean and/or replace as required.
3. Clean and/or replace all strainer screens. Note: The screen in the priming line strainer must be
cleaned from time to time and the other devices in the priming line may need to be replaced as
well. The plug on the strainer provides access to visually check the screen. The plug should not
be removed while the system is under pressure.
4. For Halar
®
coated deluge valves, check the Halar
®
coating for physical damage. If necessary,
make repairs to the affected area to inhibit potential corrosion. Refer to the paragraph below -
Halar
®
Coating Repair instructions.
5. Refer to PLACING THE VALVE IN SERVICE in the appropriate deluge valve technical data page.
Every Fifth Year
1. Internal inspection of deluge valves is recommended every five years unless inspections and
tests indicate more frequent internal inspections are required. Refer to Disassembly instructions
provided below.
2. Internal inspection of strainers and restricted orifices is recommended every five years unless
inspections and tests indicate more frequent internal inspections are required.
3. Record and provide notification of inspection results as required by the Authority Having Jurisdiction.
