Lesson 1/Learning Event 2
NOTE
Any other suitable container (such as a 55-gallon drum) may be
used.
Make certain that the open end of the fuel tank hose is
low in the fuel container so that the maximum amount of fuel can
be used.
Step 3.
Remove the cap from the quick-disconnect coupling-half hose
connector at the skid-assembly base.
Connect the fuel-return hose quick-
disconnect coupling half to the connector.
Pull on the connected fuel-
return hose to make certain that it is securely fastened.
Step 4.
Remove the cap from the fuel-supply hose connector at the skid-
assembly base. Connect the fuel-supply hose quick-disconnect coupling half
to the fuel-supply connector.
Pull on the connected fuel-supply hose to
make certain that it is securely fastened.
Loading Supplies and Protective Clothing
Load supplies in the quantities needed on the vehicle or trailer being used
to transport the M12A1 PDDA. See that protective clothing for the five-man
crew performing decontaminating operations is available and ready to use.
Test Spraying
Test spraying will be done as the last procedure in preparing the M12A1 PDDA
for operation. Use the following steps to perform test spraying.
Step 1. Fill the tank-unit assembly with 200 gallons of water. Remove the
cover and check the water level on the tank liquid-level indicator. Inspect
all pipe connections and valves for signs of leakage.
Step 2. Discharge half of the water in the tank through the gun assemblies
and half of the water through the showers. Inspect the discharge piping and
hoses for signs of leakage.
For new equipment, water flowing through the
pump unit will clean preservative lubricant from inside the piping and
valves. Inspect for unusual noises or erratic operation of the pump. See
that the pump discharge pressure gage is indicating 60 -120 psi during pump
operation.
Step 3. After test spraying, flush and drain the ABC-M12A1 decontaminating
apparatus immediately.
