COMMISSIONING OVERVIEW
Commissioning/Initial Start-Up
Preparations
Before operating the MTC, we recommend determining the amount of contaminants, free water, and sludge in the tank.
AXI International provides a variety of tank sampling equipment, including Sampling Pumps, tubing and bottles, as well as
Tank Samplers (“Bacon Bomb”) – please see our FS Fluid Sampling line of products. Please make sure the samples are
taken from the bottom of the tank (in the deepest spot). Use a stick with “Kolor Kut” paste on the end, reach through the top
of the tank, and place the end of the stick all the way at the bottom of the tank. Kolor Kut paste will show the water level in
the tank, and indicate how much water, and sludge, will have to be removed. Call AXI International for further information
on other fuel sampling equipment.
General Tank Cleaning Procedure
In Fine Filtration Mode, the MTC system is continuously restoring, reconditioning, and returning the fuel back to the tank.
Fine Filtration mode will continuously remove particles as small as 1 micron, utilizing high efciency spin-on lters.
We always recommend keeping a “before” and “after” bottom tank sample for “show & tell” purposes to demonstrate the
improvement of fuel color, clarity, and opacity.

REV0303HC300010318
OVERVIEW
OPERATION
System Operation
Operating Procedure
Hoses: The intake/suction hose is a reinforced vacuum hose. The return hose is black or blue/black, non-marking, high
quality, discharge fuel hose. Both hoses are equipped with quick disconnects or Cam & Groove couplings.
1. Attach quick disconnect end of suction hose to the quick disconnect Pre-Filter Inlet Port of the MTC.
2. We highly recommend attaching a “stinger” or pipe (cut at an angle at the end that goes into the tank and is at minimum
the same inner diameter as the suction hose) to the suction hose to reach the lowest part of the tank bottom.
3. Attach quick disconnect end of blue/black discharge hose to quick disconnect Pump Skid Discharge Port (before ne
lters) of the MTC.
4. Place the end of the discharge hose in an appropriate-size container (Phase One only). Try to not agitate the fuel in the
tank and stir up and disperse water and sediment throughout the fuel –this will make it more difcult to remove later on.
5. For Phases Two and Three, place the end of the discharge hose back in the tank as far away as possible from the
suction hose. Ensure that the hose is secured and will not vibrate out of the container when the system is operating.
6. Verify that drain valves are closed and the system is set up in a stable and safe position.
Note: Never restrict the ow on the suction side of an MTC; e.g. by using a smaller ID hose or pipe or attaching the suction
hose to a tting on the tank that has a smaller ID than the hose. This will lead to excessive pump load, noise and ultimately
damage the pump.
AXI recommends 3 phases to successfully polish a fuel tank:
• 1. Bulk water and sludge removal
• 2. Pre-ltration
• 3. Final fuel polishing
This will ensure all water is removed from the fuel, particulate is removed, and the fuel is in an optimal condition. The goal
of Phase One is to remove any free water and sludge on the bottom of the tank without mixing the water into an emulsied
state within the fuel. Start the pump motor and be ready to immediately stop it. The vane pump will start pumping as long as
the system is primed and the suction lift is not excessive. The ow of fuel can be observed in the suction hose. Watch for a
steady ow of fuel into the container. Connect the Discharge Hose to the Pump Skid Discharge Port (before ne lters). It is
also recommended to install a small ball valve on the suction “stinger” to break the vacuum for draining.
Phase 1:
1. Connect a “stinger” to the tank end of the suction hose. The stinger is obtained locally and fashioned according to the
requirements of the particular job. In general, the “stinger” is a piece of PVC pipe cut at an angle to facilitate removal of
water and contaminants, when the “snorkel” is inserted into the fuel tank.
Note: Avoid restricting the ow on the suction side of the system. If it is necessary to use a smaller ID suction hose, a smaller
ID “stinger”, or if the length of the suction hose is increased, reduce pump speed with the Speed Control Dial so that the
vacuum gauge remains in the green color band. The system’s PLC controller will halt system operation automatically if the
suction vacuum exceeds safe limits.
Note: To adjust vacuum settings of MTC HC-300, please contact AXI International.

2. Connect the Suction hose to the System Inlet Port.
3. Connect the Discharge Hose to the System Discharge Port
4. Check all connections for integrity.
5. Install a large micron (200µ or larger) bag lter in the Bag Filter Vessel and close vessel securely.
6. Ensure no ne lters are in either of the last two lter vessels.
7. Open the Inlet Ball Valve.
8. Open the Discharge Ball Valve.
9. Insert suction “stinger” into the tank and secure.
10. Insert discharge hose into separate container for disposal (removal of unwanted contaminants).
11. Verify that the “MANUAL/OFF” switch is in the “OFF” position.
12. Connect the system to an appropriate power source.
13. Verify that the Variable Frequency Controller dial is set at 20-30, so that the pump motor will start at lower intial speed.
14. Switch the Smart Filtration Controller circuit breakers to on - the “System Power” light illuminates.
15. Switch the Smart Filtration Controller to “MANUAL” to begin pumping.
16. If the pump does not start, toggle the Variable Frequency Controller Lever switch to “Start”. This will be necessary for
the rst cycle after the Smart Filtration Controller circuit breakers are switched on.
17. Observe System Priming.
18. Check for leaks or other abnormalities.
19. If anything deviates contact AXI International immediately
Phase 2:
After removing the bulk of the sludge and water from the tank into a separate container for disposal, the return hose is now
inserted into the tank, ending Phase One. The goal of Phase Two is to remove any additional free water within the tank and
also remove any large contaminants and sludge. This phase will clean the fuel and should be a precursor to using the more
expensive ne lters (which are higher efciency and cost). It should be noted that meeting required cleanliness codes is
typically not possible with pre-ltering alone. Phase Two is used to extend the life of the ne lters, and remove the worst of
the contaminants, before polishing with ne lters to meet the required cleanliness.
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 sufcient access to the tank. In some cases, both hoses will
have to be inserted through the same tank ll 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 ensure proper fuel ow.
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 from the bottom of the pre-lter.
Check the sump of the pre-lter periodically for build-up of free water.
3. The MTC should be kept running in the Phase Two recirculating mode until clean fuel samples can be drained from the
pre-lter. Then, switch off the pump for nal polishing.

OVERVIEWOPERATION
Phase 3:
Phase Three is the most important phase in meeting specic cleanliness codes. Unlike the pre-lter, the ne lters typically
use absolute rated media. Absolute lters have a very high efciency and will ensure that fuel leaving the system is clean to
specication and has a low water content. Like previously mentioned, pre-ltering should be performed to remove any large
particulate, water, and sludge. Pre-ltering will extend the life of the ne lters.
1. Connect the Discharge Hose to the Discharge Port (after ne lters).
2. Ensure catridge lters are in the rst and/or second stage of nal lter vessels.
3. Increase pump motor speed as appropriate to continue fuel polishing and fuel restoration process.
4. Limit motor overspeed operations to light load conditions. Motor over speed is when the speed indicator window
indicates greater than the nominal 60 Hz. 60 Hz is the normal “rated RPM speed” of the motor. At 60 Hz, (displayed in
the Speed Indicator Window) Flow Rate will be approximately 300 GPM (attainable with new/lightly loaded lters).
5. Monitor process and change bag lters and lter elements as necessary.
6. Bag lter vessel is equipped with a vacuum gauges. Final lter vessels have pressure gauges to show the pressure
condition of the pump. Differential gauges are installed to show the pressure drop over each lter individually.
7. Now is the time to add AXI International AFC-710 Fuel Catalyst in a dose of 1 : 2500 or 1 gal of AFC-710 for 2500 gallons
of fuel. Higher doses of AFC-710 may be necessary depending on condition of fuel.
Note: System can run with ne lters in one, two, or none of the nal lter vessels. This allows for phasing of the fuel
cleaning process
Note: Pre-lter should always have some type of pre-lter bad in place during operation to extend life of the pump vanes.

OPERATIONPRIMING OVERVIEW
AFC Fuel Additive
The use of AXI International AFC-705/710 Fuel Additive is an essential part of any tank cleaning and fuel polishing procedure,
as AFC can more rapidly and efciently decontaminate and clean the entire fuel system. The additive is best introduced into
the process after Fine Filtration Mode. Before dosing the tank with AFC-705/710, remove as much of the sludge and free
water as possible. Adding AFC-705/710 to the tank will speed up the cleaning process by breaking down and dissolving the
sludge covering the tank walls and bottom.
AFC-705/710 will decontaminate areas and sections of the tank that are out of reach of the suction hose. It is recommended
to use a higher concentration of one to twenty ve hundred (1:2500) instead of one to ve thousand (1:5000) for the rst
treatment. This has proven to be very helpful in accelerating the rate of dissolving sludge. Higher doses may be necessary,
depending on contamination level of the fuel. AFC-705/710 is a full spectrum fuel additive, containing a combustion catalyst,
surfactant (705), detergent, dispersant, corrosion inhibitor, lubricity enhancers, and a fuel stabilizer that eliminates the need
for expensive, toxic biocides.
*Note: AFC-705 contains a surfactant. Surfactants can emulsify water into the fuel and damage HPCR injection systems.
Consult AXI for recommendations on fuel treatment.
After Fuel Polishing Process
1. Stabilize the Fuel
AFC-705/710 will stabilize the fuel in tanks used for long-term fuel storage. When a recirculation or STS Automatic Filtration
System is not in place, AFC-705/710 will maintain fuel quality and prevent formation of sludge for up to twelve months.
Added after the fuel polishing process, it is not necessary to add more AFC-705/710 until additional fuel is added into the
tank, or an environmental condition for the fuel has been altered (introduction of water or other contamination)
2. Prevent Water from Accumulating
The use of AXI Water Eliminators, or tank breathers, will prevent water from accumulating in the tank. The water eliminators
will absorb and remove any water from condensation or other sources. Preventing water accumulation eliminates microbial
growth and the need for toxic biocides.
3. Monitor Fuel Quality
Liquid-Cult Fuel Test Kits are ideal for monitoring your fuel supply for microbial contamination. The tests provide indication
of bacterial and fungal activity.
4. Intelligent Fuel Management Solutions
AXI International Intelligent Fuel Management Solutions signicantly lower operating costs, save fuel, eliminate periodic
tank cleaning and the build up of solids, sludge, and acids. AXI International Technology enhances personnel safety and
addresses environmental concerns by preventing the need for costly toxic biocides. Larger capacity Mobile and Stationary
Tank Cleaning Systems are available.
! IMPORTANT ! It is recommended that only qualied, experienced personnel, familiar with this equipment,
who have read and understood all the instructions in this manual should operate and maintain the system.
! WARNING ! Do not use with gasoline, solvents, corrosive liquids, food liquids or other liquids having a

PRIMING OVERVIEW
Priming the System
Note: The system is equipped with a positive displacement vane pump. It should never be run dry and started without the
hoses attached and/or valves in the closed position. Failure to do so may damage the bypass valve and/or pump.
Priming Procedure
Before turning on the pump make sure the entire suction side of the MTC system (suction hose, separator, plumbing, pump,
strainer …) is primed and lled with oil/diesel fuel. Running the pump dry could cause pump damage and pump to not
operate properly.
Note: The separator/coalescer has to be full at all time to perform properly.

CONTROLLER OVERVIEW
Controller
Manual/Off
Manual- Normal pump/system on/off control.
Note: Unsupervised operation of the system is not recommended or supported by AXI International. The system requires
full-time technician monitoring whenever in operation. Please call AXI with any questions.
Circuit Breakers
3 Phase: 30 Ampere 3-gang breaker for Variable Frequency Controller and pump motor (Left gang), 3 Phase 10 Ampere
3-gang breaker for electronics (Right gang).
Variable Frequency Controller
In normal operation the Variable Frequency Controller is used ONLY to change the speed of the pump. When the Smart
Filtration Controller is switched to “Manual” the pump will turn on and accelerate to the VFD speed.
Speed Indicator Window
The number shown on the Variable Frequency Controller display is the frequency of the current that is being sent to the
pump motor. 60 Hz for example is the rated speed of the motor. If the Variable Frequency Controller display indicates 30,
this means that the pump is turning at ½ of the rated speed.
Speed Controller UP and DOWN Arrows
Changes pump speed from 10 Hz to 60 Hz.
Note: ALL other Speed Controller Control Pad Functions (Run, Stop, Forward, Reverse) are disabled.
Alarms
The system is equipped with an AXI International Smart Filtration Controller. System and alarm status are displayed on the
industrial control panel (on the door) via indicator lights, and LCD screen on PLC inside.
Alarms featured on the system include:
• Leak Detection
• Primary lter high vacuum alarm indicator and system shutdown (vacuum sensor)
• Secondary lter high pressure alarm indicator and system shutdown (pressure sensor)
• High vacuum differential alarm indicator and system shutdown (differential switch)
• High pressure differential alarm indicator and system shutdown (differential switch)
Once triggered alarms are addressed, each alarm can be reset by pressing the weatherproof “ALARM RESET” push button
located on the outside of the enclosure door.

MAINTENANCE OVERVIEW
Maintenance
! IMPORTANT ! It is recommended that only qualied, experienced personnel, familiar with this equipment,
who have read and understood all the instructions in this manual should install, operate and maintain the
system.
! IMPORTANT ! Always disconnect the system from the electric power supply before working or servicing
it. Do not proceed with any maintenance unless the pressure or vacuum has been released, the system has
been allowed to reach ambient temperature and all uids have been drained.
Draining and Storing the System
1. Set pump motor to operate at a low speed - 10-15 Hz in the Speed Indicator Window
2. Remove Suction Hose “stinger” from tank allowing air to be drawn into the system through the “stinger” (or open ball
valve to atmospheric on top of “stinger”).
3. Continue at low pump speed until the system is purged of fuel as indicated by a lack of fuel in the suction hose.
4. Purge the pre-lter: Continue at low pump speed and allow unit to clear.
5. Ensure all fuel is cleared from the HC-300.
6. Terminate pump operation when all fuel is purged
7. Disconnect all hoses and contain any fuel remaining in hoses
8. Cap hoses as appropriate
Pump
Check pump for leaks, worn vanes and if bypass valve operates correctly. Keep the pump lubricated and pour some oil into
pump head for storage.
Suction and Discharge Hoses
We recommend replacing both the suction and discharge hoses every two years. Heavy use, visual deterioration, damage
or poor condition and excessive wear can require an even earlier change.

MAINTENANCE OVERVIEW
Servicing Fine Filter(s)
There are two types of AXI International ne lters available.
1. 2 to 30 micron high efciency particulate lter
2. 5 to 30 micron water block ne lter
The AXI International Water Block removes entrained and emulsied water from fuel and oil.
Changing Filters:
Pending all buttery valves are open, a differential pressure drop of 22 PSI, as shown by the differential pressure gauges on
the nal lters, indicates that the nal lter elements of that vessel need to be changed.
1. It will be necessary to purge as much fuel as possible from the nal lter vessels.
2. Close the inlet valves on the pre-lter to prevent more fuel from entering the system.
3. Open the bleeder valve on top of each primary lter to allow air into the system.
4. Turn on the Smart Filtration Controller using the breakers to power the Variable Frequency Controller.
5. Turn on the pump to remove the fuel in the system until the suction hose is empty.
6. Turn off the pump.
7. Fuel level in nal lters should be sufciently low to change the elements.
8. Remove dirty elements and replace with correct elements for the application.
9. Open the vent valves on the nal lter vessels to release any remaining pressure. Open lids and replace.
10. Apply a lm of lubricating oil to the lid gasket. Replace O-Ring if worn or damaged.
11. Tighten lid screws evenly (alternating the screws) to ensure lid is fully seated onto O-Ring gasket.
12. Close primary and nal lter vent valves.
13. Open inlet valves on system skid.
14. Resume pump operation and check for leaks.
Note: All lters within each lter vessel should be identical.
The material trapped inside the lter can be inspected to better understand the types of contaminants that have been
removed from the tank.
Note: Disposal of fuel, associated waste, and lters must be in accordance with all applicable Federal, State, and Local
rules, laws, standards, and regulations.

MAINTENANCE OVERVIEW
Servicing Bag Filter
Note: Always have an adequate supply of lter elements/bags on hand.
Changing Bag Filters:
At 15”HG vacuum, the bag lter elements should be replaced.
1. For a “no mess” bag lter change, the bag lter vessel should be pumped empty. To accomplish this, remove the suction
“stinger”, or open atomspheric vent on top of “stinger”.
2. The pump will begin to purge the fuel out of the lter vessel as air enters the vent.
3. When the pre-lter vent is empty, replace bag lter elements and make sure it seals tight within the perforated basket.
For best results, bags should be fully extended into the basket. Check inner housing and basket for debris and sludge
and remove if necessary. Also, ensure that the basket is seated correctly and tight on the S.S basket within the bag
lter vessel.
4. Apply a lm of lubricating oil to the lid gasket. Replace O-Ring if worn or damaged.
5. Tighten lid screws evenly (alternating the screws) to ensure no air can enter the system and that the lid is fully seated
onto O-Ring gasket.
6. Close the vent valve.
7. Open the inow and outow valves of the system with the new bag lters to resume operation of the system. Check for
leaks and air intrusion.
8. The material collected inside the lter bag can be inspected to better understand the types of contaminants that have
been removed from the tank.
Note: Disposal of fuel, associated waste, and lters must be in accordance with all applicable Federal, State, and Local
rules, laws, standards, and regulations.

Safety Notes
• The MTC Pump is designed to be used with diesel fuel and oils only. The pump is NOT designed for gasoline, alcohol
or other explosive or corrosive liquids.
• Please contact us if you are not sure if the liquid you are intending to polish and clean is compatible with the MTC
system.
• Biocides are extremely toxic and may enter the body through the skin. It is recommended to use adequate protection
and avoid skin contact with biocide-treated fuels and oil.
• Disposal of tank sludge, water and lter elements should be done in accordance with Federal, State and Local
regulations. These materials need to be treated as chemical waste.
! WARNING ! DO NOT USE WITH GASOLINE. This System is not meant for use with gasoline nor with other
ammable liquids having a ash point less than 100°F (38°C). Use with gasoline or any ammable liquids
at a temperature exceeding their ash point, presents explosion and re hazards.
! WARNING ! Care must be taken not to operate the pump with either the suction (inlet) or discharge (outlet)
lines closed or obstructed. If the pump is allowed to run without fuel serious damage may occur. Only run
the system when you are able to supervise it. Unattended Operating of the MTC is NOT recommended.
! WARNING ! Some fuels may have been treated with biocides. Biocides are extremely toxic and may enter
the body through the skin. Use adequate protection and avoid contact.
