Section III.
OPERATION UNDER USUAL CONDITIONS
2.4 SYSTEM ASSEMBLY AND PREPARATION FOR USE. (Refer to figure 2-3.)
Figure 2-3 illustrates a typical AAFARS emplacement. Actual emplacement may require a slightly different configuration due
to terrain or mission constraints. Select a site that is flat and clear of rocks, stumps and debris.
Death or personal injury may result from the explosion of fuel fumes exposed to an open flame or
spark, or to static discharge. Do not permit smoking, any open flame, or spark producing equipment
within fifty (50) feet of AAFARS. Ensure all equipments are well grounded prior to commencing any
operation or maintenance task. Always ensure the ground connection from the aircraft is complete
prior to beginning any fueling operation.
Serious injury could occur if heavy equipment is moved/lifted without sufficient personnel to do the
.Job.Always use four personnel to move or relocate the pump-engine module, liquid fuel filter-
separator, and accessory module. Use proper physical lifting procedures or use a suitable lifting
device or dolly. Wear safety shoes, gloves, and other suitable protective clothing.
All couplings have caps that must be removed before a connection is made. Ensure the cap remains
in place until just before connection to prevent contamination of the fueling system by
foreignmaterials.
Once the caps are removed, couple adjacent caps to reduce the probability of
foreign materials contaminating the aircraft fuel.
a.
Position fuel drums (1). Fuel drum (1) may roll. Insert chocks or dirt berms on both sides.
b.
Inspect AAFARS for damage that may have occured during transport and ensure system is complete.
c.
Unlatch and open all AAFARS bags.
d.
Remove engine module from pump-engine module. (Refer to figure 2-4.)
(1) Unclamp, exhaust pipe (1) from exhaust manifold (2).
(2) Disconnect pumpage over temperature cable (3) at engine module connection panel (4). Install dust caps on
connectors. Wrap free end of cable around fuel transfer pump outlet (5).
(3) Disconnect fuel supply line (6) and return line (7) at engine module. Connect free ends of lines together.
(4) Unlatch (8) engine module (9) from pump-engine frame (10) and slide engine module out of frame.
