OPERATING PROCEDURES
WARNING
Death or personal injury may result from the explosion of fuel fumes exposed to an open flame,
spark, or to static discharge. Do not permit smoking, any open flame, or spark producing equipment
within fifty (50) feet (15.24 m) 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.
Fuels are toxic and flammable. Wear protective goggles and refuel only in well ventilated areas.
Avoid contact with skin, eyes, and clothes and don't breathe vapors. Do not use near open flame or
excessive heat. If you become dizzy, get fresh air immediately, flush with clean water and get medical
aid for eyes immediately.
Use single hearing protection within 22 feet. Hearing can be permanently damaged if exposed to
constant high noise.
CAUTION
System components are subject to damage from thermal expansion. As the temperature increases,
the pumpage in any component will expand. If trapped in a component, the expanding pumpage
may rupture seals and cause a leak or equipment malfunction. For this reason, all system valves
should remain open as long as the system is flooded. With all valves open, the hoses will absorb the
expansion and protect system seals. If any component must be isolated, it should be drained or
defueled immediately to prevent damage.
NOTE
During operation, monitor the filter-separator differential pressure gauge. If a pressure differential
of more than fifteen (15) psi is observed, the fuel flow is being restricted and the coalescer
elements should be replaced.
Assure that one person stands by the control panel at all times during operation to control the
AAFARS.
1.
Conduct a visual inspection of the AAFARS setup to ensure the system is properly assembled and ready to pump fuel.
Verify system grounding.
2.
Verify/Position fuel selector valve in INTERNAL TANK or EXTERNAL TANK position, according to desired fuel
source.
3.
Verify that manual start control is fully lowered.
4.
At the fuel drums, open the fuel drum outlet elbow valve couplings, allowing pumpage to flow.
