3. The Tank Sweeper™ will remove the bottom contents of the tank
where the majority of fuel contaminants exist, i.e., water, crude,
algae and rust. If a badly contaminated tank is expected, it would be
best to run the cleaning through the lower filter housing without the
screen. The Sweeper™ function incorporates a 150 micron screen
which can capture the majority of the rust and large contaminates.
However, the screen openings can still be clogged up quickly
causing an implosion of the screen and a reduction of the flow.
The Tank Sweeper™ operator should move the Fiber Staff back and
forth across the bottom of the tank moving the stick when the oil shows
clear in the hose. You will see it turn black then when that spot is clean
it will turn red, this is the indication to move the staff to another spot on
the bottom of the tank. Repeat this sweeping function until only clean
fuel is removed. It may be necessary to use two 55 gallon drums
depending upon the amount of contaminates found.
NOTE: Be mindful of the 55 gallon drum level and be sure not to
over-fill. Have your Emergency Spill Kit ready and available in
case of a spill. Leave sufficient air space for expansion.
After the sweeping is complete, remember to lower the tank to a
level position by removing the jack.
Remove the outlet hose from the 55 gallon drum and install all
vent or port caps and seal drum completely for transport.
FILTERING AND BLENDING THE FUEL:
A great feature for the Sweeper™ is the ability to return the
contaminated fuel clean and filtered to the same or new oil tank. To do
this, allow the 55 gallon drum with the fuel that came from the sweeping
to sit and settle for 24 hours.
1. Turn the main Ball Valve to the Filter Selection and you can complete
the fuel restoration. Observe all instruction on page 1, 2 and 3 (up to
Tank Sweeping™ section.)
2. Install the outlet hose in the tank you want to transfer the cleaned
fuel into.
3. Insert the Fiber Staff on the Filter intake side into the top of the 55
gallon drum allowing it to just contact the fuel at the top of the drum.
NOTE: When ready to sweep the tank, be sure to check all
connections for leaks and be prepared to shut down the sweeper
in the event of a leak. Have your Emergency Spill Kit available and
in reach. It is best to have this operation performed by two people-
-one operating the air supply and the other person doing the
actual sweeping of the tank.
4. When in the filtering mode and turning the air valve to the ON
position, slowly lower the fiber staff into the 55 Gallon drum following
the fuel level watching the clear hose for signs of black
contamination. The contaminates will be settled in the last few
inches of the drum so when you get close to the bottom and as soon
as you see the color of the fuel change to dark, lift up the fiber staff
and stop the transfer operation. Dispose of the bottom of the tank
with the contaminated fuel properly.
