SYSTEM ASSEMBLY AND PREPARATION FOR USE (Continued)
Figure 4. Pump-Engine Emplacement
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 is closed before connection to fuel drum. Failure to heed this
warning could result in death or serious injury.
