2-16. ASSEMBLY AND PREPARATION FOR USE - CONT.
r.
Fueling Point Ground Rod Installation. Refer to figure 2-26.
WARNINGS
•
Do not touch surfaces with bare skin. Bare skin will freeze to
metal surfaces in subzero temperatures. Always wear arctic
mittens when handling components.
•
Use care to prevent injury when driving ground rod into the soil.
Wear gloves to protect your hands. Do not hold ground rod
above the stop collar.
•
Do NOT operate the fuel system until it has been properly
grounded. Fuel flow can generate static charges which could
ignite the fuel or cause an explosion of fuel vapor.
NOTES
•
Before the AFSSP can be placed in operation, it must be
properly grounded. Install ground rods at three refueling points,
two drum filling points, two bottom loading points, three 200
GPM filter-separators, two 600 GPM pumps and two receiving
points.
•
If ground cannot be sufficiently penetrated, bury the ground rod
in a trench not less than four feet long and at least eight inches
beneath the surface.
•
Nozzle ground clamps maybe used to supplement aircraft
grounding rod.
(1)
Place ground rod (1) in vertical position.
(2)

soil (rod will be at least three feet deep).
(3)
Connect connector (4) to either fuel nozzle (5), 3-inch tank coupler (6), 4-inch ball valve (7) or 6-inch
valve section (9).
