inletof the 2 innerfueldrums.
(2)Connect the 2" x 6' suction hoses (6) to a wye fitting (16). Open 2" unisex coupling valves on wye fitting
and suction hoses.
(3)Connect a unisex cross fitting (17) to the free leg of the wye fitting (16). Open 2" unisex coupling valve at
wye-cross connection.
(4)Connect a 2" x 12' discharge hose (18) to the cross fitting (17) and the non-valved unisex coupling (2)
mounted on the inlets of the two outer fuel drums. Open unisex coupling valves at cross discharge hose
connections.
NOTE
Three recirculation paths are available for use as indicated on figure 1-17.
RECIRC 1 (figure 2-3, 19) limits flow to 5 gpm from the recirculation manifold
(RECIRC 1 is normal recirculation path during fueling operations); RECIRC 2
(20) allows full flow; and RECIRC 3 employs the nozzle recirculation wye (21)
to recirculate fuel from a CCR or D-1 nozzle. The supervisor must select a
method based on mission requirements.
s.
Connect a 2" x 50' discharge hose (22) between the cross fitting (17) and RECIRC 1 coupler (19) on the
recirculation manifold.
Open 2" unisex coupling valves at each connection.
t.
Open fuel drum inlet elbow valve couplings (2) and 2" unisex valve coupling and discharge hose.
u.
Drive a grounding rod between the pump-engine module (3), accessory module (8) and the liquid fuel filter-
separator (7) for grounding AAFARS.
v.
Connect the pump-engine module (3), accessory module (8) and liquid fuel filter-separator (7) grounding cables
to the grounding rod.
w.
Position a fire extinguisher at each fueling point and pump-engine module (3).
x.
Position one nozzle kit and one grounding rod at each fueling point.
y.
Drive one grounding rod at each fueling point, approximately 10 ft (3 m) back from discharge hose end.
Never operate the flow actuating handle of the CCR nozzle unless nozzle
diaphragm is wetted by fuel. Actuation of this handle when the
diaphragm is dry may result in irreparable damage to the diaphragm,
rendering the nozzle unusable.
z.
At each fueling point, select the nozzle for use, connect to the discharge hose end and connect the nozzle
grounding clamp to the ground rod.
aa.Remove the engine air filter from the storage cabinet in the accessory module. Remove dust cap from intake
manifold and install engine air filter with center clamp facing up.
ab.Verify position of toggle switches on control panel (figure 2-1) as follows:
(1) Open control box cover.
