4. To operate the system, your soldiers must first prime the pump and start
the centrifugal pump engine. Refer to the appropriate TM for the operating
instructions of your specific model of the 125-GPM pump. Check the entire
system for leaks, beginning with the 2-inch elbow couplers on the water
storage and dispensing drums.
If a leak is discovered, shut off the
centrifugal pump engine.
If the leak is at a quick-disconnect coupling
assembly, open and remove the assembly.
Inspect the hose assembly for
abnormal twisting or ballooning which indicates that the hose is weak.
Also, check the couplings to be certain the sealing gaskets are in place,
and for damage or the presence of foreign matter. If gaskets are damaged or
missing, obtain these items from the overpack kit and replace them.
If
couplings are damaged, replace the entire assembly with a space assembly
from the overpack kit. If foreign matter is present, thoroughly flush the
hose. Refasten the assembly. Start the engine of the centrifugal pump, and
repeat the above procedure until no leaks are observed.
5. Test each of the four distribution nozzles. If they do not operate at
full flow, stop the centrifugal pump engine. Check the strainer inside the
nozzle, clean it if needed, and replace it.
Start the centrifugal pump
engine, and repeat the procedure described above until all distribution
nozzles operate at full flow. You should now perform during-operation PMCS.
6. Perform
after-operation
PMCS
prior
to
equipment
disassembly.
Disassemble the FAWPSS in the reverse order of assembly.
Prior to
repackaging, drain, dry, and then cap and plug all hose assemblies. Drain,
collapse, and fold the water storage and dispensing drum.
In the
disassembly of the FAWPSS, it is important to consider the following
factors:
a. Ensure that all component parts
are
stored
in
the
original
containers in which they were received.
b. Ensure that dust caps and plugs are replaced on each hose prior to
repackaging.
c. Ensure that component parts of the various hose assemblies and other
fittings are disassembled in the following order for repackaging:
(1) Water storage and dispensing bag assembly.
(2) Distribution nozzle assemblies.
(3) Tripod stand assemblies.
(4) Four swivels.
