1.
Insert blue/black discharge hose into tank as far away from the suction hose as possible. In some cases, it is
recommended to remove the sending unit cover to gain sufficient access to the tank. In many cases, both hoses will
have to be inserted through the same tank fill opening.
2. After verifying that both hoses are properly placed in the fuel tank and that the valves on the MTC system are in the
correct position, switch on the pump and watch the clear suction hose for fuel flow.
Depending on the amount of contaminant in the tank, we recommend you stop the pump shortly after priming and check
for free water and sludge by draining the water separator. It may be necessary to depress the air purge valve on top of the
separator after opening the drain valve.
Repeating this process and observing the fuel flow will indicate how long the pump should run before it is necessary to drain
the separator.
3. The MTC should be kept running in the Phase Two recirculating mode until clean fuel samples can be drained from the
separator. Then, switch off the pump for final polishing.
4. Now is the time to add AXI International AFC-705 Fuel Catalyst in a dose of 1 : 2500 or 1 gal of AFC-7010 for 2500
gallons of fuel. Higher doses of AFC-705 may be necessary depending on condition of fuel.
Phase 3:
Phase Three is the most important phase in meeting specific cleanliness codes. Unlike the pre-filter, the spin-on filters
typically use absolute rated media. Absolute filters have a very high efficiency and will ensure that fuel leaving the system is
clean to specification and has a low water content. Like previously mentioned, pre-filtering should be performed to remove
any large particulate, water, and sludge. Pre-filtering will extend the life of the spin-on filters.
1. Connect the return hose to Discharge Port 2.
2. Start the pump and the system will run in the re-circulating mode restoring the fuel to its optimal pristine and sparkling
condition.
3.
Monitor the pressure gauge on the filter head. When the pressure reaches 20 - 25 PSI, or reaches the red area it is
time to change the filter.
Note: FF-3, FF-10 and FF-25 filers are only for particulate removal and will allow water to pass through – for complete water
elimination we highly recommend to finish a tank cleaning job with a WB-3 or WB-10 filter.
!WARNING! The whole system (enclosure, doors, plumbing, motor, electric sub panel) must be properly
grounded for operator safety.
Note: The built in bypass-valve on the systems pump can be adjusted for your requirements. If the adjustment screw is
all the way out, the valve is set to the lowest possible pressure. Turn screw on bypass valve clockwise to increase bypass
pressure if necessary (see also pump instructions).
