6. Ready Diesel-Driven Distribution Pump P-8.
CAUTION
When adding fuel to the tank, be careful not to push the screen filter into the tank.
a. With the fuel tank removed from the diesel-engine skid and setting outside of the TWPS,
add fuel as needed.
b. Take the 24-volt diesel engine starting cable out of the diesel generator battery storage
compartment (A-TPWS only)
c. Lay out but DO NOT CONNECT the 24-volt diesel-engine starting cable from the diesel
generator 24-volt slave outlet to where the diesel engine-driven pump is to be placed.
d. Place the pump insulating platform on the ground near the diesel generator 24-volt slave
outlet.
WARNING
Three person lift. Three people are required to lift Diesel-Driven Distribution Pump
P-8. Lift with your legs, not your back. Failure to observe this warning may result
in back injury.
e. Open the flap at one end of the top of the insulating cover and the hook and loop seam at
the other end and grab the frame in three places to lift the P-8 pump skid.
f. Move the P-8 pump off of the TWPS skid to the pump insulating platform.
g. Set the fuel tank in place on top of the P-8 skid outside of the pump insulating cover.
Complete the fuel hose connections through the opening in the cover (red-banded supply
hoses together and yellow-banded return hoses together).
h. Immediately connect the 24-volt cable first to the diesel-driven pump (see Figure 30.)
i. Connect the 24-volt cable to the diesel generator 24-volt slave outlet (see Figure 30.)
j. Be sure the pump drain valve is closed.
k. Be sure that the pump inlet connection is capped.
l. Fill the pump with product water through the outlet connection, then cap the pump outlet.
7. Immediately start the diesel engine as follows:
a. Open the fuel cock at the bottom of the tank. (The lever points down when open.)
b. Set the engine speed lever to start.
c. Toggle the start switch up (on the pump skid junction box) and hold until the engine
starts. If it does not start after10 seconds, wait for about 15 seconds and try again.
d. Set the speed back to idle.
e. Disconnect the 24-volt cable first from the diesel generator 24-volt slave outlet.
f. Then disconnect the 24-volt cable from the diesel-driven pump.
8. Set up the P-8 pump at its final location as follows:
a. Move the pump off of the pump insulating platform.
b. Move the insulating platform to the final pump location.
c. Lay an absorbent pad on the platform to adsorb any oil or fuel spills.
