(10)
Remove cover (19) from coupling (20) on recirculation nozzle (21).
(11)

coupling.)
i.
Ground Rod Installation. Refer to figure 2-12. Before the HTARS can be placed in operation, it must be properly
grounded. A ground rod with a built in slide hammer is supplied for each refueling point. Ground rods must be
installed within 6 feet of each refueling point to provide enough slack in grounding cable to connect nozzles to
aircraft adapters.
WARNINGS
·
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. Flow fuel
can generate static charges within the fuel hoses. A static discharge could
ignite the fuel or cause an explosion of fuel vapor.
(1)
Place ground rod (1) in vertical position.
(2)
Raise, then lower slide (2) forcefully against stop collar (3). Repeat until collar is flush with surface of soil
(rod will be at least three feet deep).
NOTES
·
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.
·
If driving ground rod becomes too difficult, try soaking the soil with water.
Continue alternately soaking, then driving the rod until installation is complete.
(3)
Using separate ground cable, ground aircraft to ground rod.
NOTE
CCR nozzle ground clamp may be used to supplement aircraft grounding or
bonding.
(4)
Connect ground clamp (4) (from CCR nozzle) to ground rod (1).
(5)
Repeat steps (1) through (3) for three remaining ground rods.
