4. INSTALLATION
Refer to appropriate NFPA Installation Standards.
5. OPERATION

and sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray
pattern to extinguish or control the fire.
6. INSPECTIONS, TESTS AND MAINTENANCE
Refer to NFPA 25 for Inspection, Testing and Maintenance requirements.

Viking Sprinkler VK479 is available through a network of domestic and international distributors. See The Viking Corporation web
