SECTION 6 – SYSTEM MAINTENANCE
UL / ULC Ex4623 Fike Clean Agent System w/ FM-200™ Page 1 of 3
FM 3010715 Manual P/N: 06-215 (Rev G) Revision Date: January, 2010
The following maintenance procedures and intervals indicated are meant to represent the minimum requirements
for Fike Clean Agent Fire Suppression systems. These procedures do not preclude those required by NFPA
2001 and the authority having jurisdiction. More frequent service intervals may be necessary if systems are
installed in more severe service applications. This section does not cover maintenance and service procedures
for the electrical and control portions of the system. Consult the appropriate product manuals for those products.
6.1 DISCHARGE PIPING
Every six months:
Check the system discharge piping for corrosion and damage. Check all piping supports to make sure they are
tight and all piping is securely supported.
Every year:
Same as six month inspection. The piping should also be blown out with compressed air or nitrogen to check for
obstructions.
6.2 DISCHARGE NOZZLES
Every six months:
Check to see that nozzle orifices are clear and unobstructed, and verify that the orifices are not showing signs of
corrosion.
Make sure the nozzles are aimed or positioned correctly. Verify that the correct nozzle part number is installed at
the proper location in accordance with the system plans.
6.3 AGENT STORAGE CONTAINERS
Every three months:
Check the pressure gauge on each container. The nominal pressure should be 360 PSIG at 70
o
F (24.8 bar @
21
o
C); however, the pressure will vary with temperature. In the range of 50°F to 80°F (10
o
C to 27
o
C) the
difference is approximately 2 psig (15 kPa) per degree. If the pressure loss indicated exceeds ten percent of the
nominal pressure, check the container for leaks and repair as necessary.
