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
Step 3. After test spraying, flush and drain the ABC-M12A1 decontaminating
