WARNING
• The AAFARS suction and recirculation hoses are connected to the fuel drums via
elbow valves with integral camlock couplers. When the elbow valve coupling is
closed, the valve stem is extended; when open, it is retracted. The stem travel is
opposite that of conventional valves and requires the operator to double check
valve position during system set up and tear down, since observation can be
misleading. Failure to heed this warning could result in death or serious injury.
•
Fuel spillage will occur if elbow valve coupling is opened before connection to a
fuel drum. Ensure elbow valve coupling closed before connection to fuel drum.
Failure to heed this warning could result in death or serious injury.
NOTE
When connecting system components, open all valves as components are
connected except fuel drum outlet elbow valves and filtration module inlet and
outlet valves. Opening unisex coupling valves at time of connection will expedite
system setup and latch couplings together. Fuel drum outlet elbow valves should
remain closed until after engine is started so that engine does not have to start
under load. Fuel drum inlet elbow valves may be opened after the unisex-to-
camlock adapters are installed. The liquid fuel filter-separator inlet and outlet
valves should remain closed until initial system flooding.
e. Inspect the eight fuel drum elbow valve (figure 2-3, 2) couplings to ensure that each elbow valve coupling is
closed (valve stem fully extended).
