Preventive Maintenance Plans for mission-critical power are
essential. However, most service agreements do not cover
fuel-related engine failures. Fuel has a limited shelf-life and
even “fresh fuel” could contain water, sediment, microbes and
bio-fuel components upon delivery.

To Tank
(Discharge)
Periodic generator tests-runs are too short to determine if fuel 1
quality is adequate for the demands of continuous, full-load
operation. In fact, generator test runs significantly accelerate From Tank
the fuel polymerization and degradation process by returning(Suction)
fuel that has been compromised by heat and pressure back to
the tank.
Potential liabilities can easily be avoided by implementing
an AXI Fuel Quality Maintenance Program as part of every
disaster recovery plan. An STS 7000 automatically maintains
fuel quality and guarantees reliable emergency power
whenever it is needed.
The system is automatically operated by the programmable
UL508A Touch-Screen Controller with Modbus, TCP/IP, LAN
and Internet connectivity. All components and control devices
are contained within a fully enclosed, lockable, weatherproof,
NEMA-rated cabinet.
The principal components are a continuous-duty motor with
coupled gear pump, a strainer/primary coalescing filter with
vacuum sensor and gauge, an ALGAE-X Fuel Conditioner and a
secondary water block fine filter with pressure gauge and sensor.

PRIMARY INSPECTION
Upon arrival, the STS 7030 Automatic Fuel Filtration System and accessories must be visually inspected
before installation. Improper handling during shipping may cause physical or electrical problems.
Immediately report or note any damages (also concealed ones) to the shipper.
CHECKLIST:
o If the packing crate shows signs of damage inspect the STS 7030 cabinet for damage. Check the
entire outside of the cabinet for damage that could indicate internal mechanical or electrical
problems.
o Check locking handles, door and hinge operation.
o Check pump/motor hardware and all plumbing connections for tightness.
o Check all electrical terminals and connections for tightness.
INSTALLATION
! IMPORTANT ! It is recommended that only qualified, experienced personnel, familiar
with this type of equipment, who have read and understood all the instructions in this
9
manual should install, operate and maintain the system.
MOUNTING
The STS 7030 is a totally enclosed system and should be permanently wall mounted on a hard, level
surface. Use provided mounting feet for proper fastening. This weatherproof unit is designed for wellventilated indoor or outdoor use within specified temperature range and should be located as close to
the tank as possible.
Please allow about 1 ft of space between the side louvers of the enclosure and nearby objects. This space
is necessary to ensure sufficient ventilation of cooling air for the system and motor.
ELECTRICAL
! WARNING ! To avoid the risk of electric shock make sure that the power supply to the
system is disconnected and ensure that the system is at zero volts, before working on
any of the system’s electrical parts.
Make sure that the systems power requirements and rated voltage / frequency match your electrical
system (See wiring diagram). The STS 7030 may only be connected to properly grounded power sources
for operator safety. Connect all components to the ground studs provided as shown on the electrical
drawings.
! WARNING ! The whole system (Enclosure, doors, plumbing, motor, electric sub panel)
must be properly grounded for operator safety.
Depending on length of run, use copper wiring according to specification in wiring diagram and connect
system to a separate UL listed breaker (not included) appropriate for branch circuit protection.
Note: Wiring and electrical installation must be in accordance with all applicable Federal,
State and Local rules, laws, standards and regulations.
Remote Pump Shut-Down Feature:
If required, connect the “external pump shut down input terminal” (see wiring diagram) and follow
the specifications provided in the electrical wiring diagram to disable pump (e.g.: remote shut down,
remote pump control, …). Please note that the contact needs to be supplied with +24V DC from the
power supply of the STS 7030 AXI International Smart Filtration Controller.
Remote Monitoring - Dry Contacts:
The STS provides two NO (normally open) dry contacts for remote alarm monitoring. Please see wiring
diagram for contact rating, connection and location.
1) “Summary Alarm” – dry alarm contact for high vacuum, high pressure, no flow or water detection
(as well as Emergency stop and overload relay triggered)
2) “Leak Detection” – dry alarm contact for leak detection
10
PLUMBING
Use proper quality approved fuel line materials with at least 2” inner diameter on the suction side
from the tank and at least 1-1/2” inner diameter on the return / discharge side back to the tank.
Note: Do not put any stress on plumbing of STS 7030 and use a backing wrench when
connecting the external plumbing. Whenever possible a FLEXIBLE CONNECTION
SHOULD BE USED TO REDUCE STRESS on the plumbing and prevent damage from
thermal expansion.
The pick-up tube/line(s) should originate from the lowest point of the tank (to remove all water),
should be connected directly to the system’s “PUMP INLET – SUPPLY FROM TANK” port located on the left
hand side of the enclosure and kept as short as possible. It is recommended to install an oversized,
low restriction foot valve to keep the system primed, especially if the “PUMP INLET – SUPPLY FROM
TANK” port of the system is located above the lowest possible fuel level in the tank. A priming tee
should be installed on the highest point of the suction line to be able to easily prime the lines and
system.
The return line(s) should be plumbed to the “PUMP OUTLET – RETURN TO TANK” port (on the right side
of the system) and enter the tank as far as possible from the pick up tube close to the tank bottom. A
(swing) check valve may be required on the return line(s) on some installations to prevent back flow
pressure.
Multiple suction and/or return lines may be connected to a manifold outside the STS 7030 (see options
list).
Anti-Siphon or other external plumbing devices may be required – please check local regulations / code.
The system capabilities are 15 ft suction (vertical) or 100 ft horizontal lift, when connected to (suction)
piping of 2” ID or more with no additional flow restrictions such as valves, 90-degree connectors or other
plumbing accessories. For continuous optimal performance, make sure suction and discharge lines are
free and that nothing is blocking the flow of fuel and that the suction line always stays primed.
11
Note: Plumbing and Installation must be in accordance with all applicable Federal, State and
Local rules, laws, standards and regulations.
TYPICAL PLUMBING / ABOVE GROUND TANK INSTALLATION (SCHEMATICALLY)
IMPORTANT INSTALLATION PRECAUTIONS
The suction line of the system should be independent and separate from the suction line of the
engine. If that is not possible, appropriate valves must be installed to completely separate the STS 7030
from the engine fuel system to prevent any possible interference with safe engine operation.
It is highly recommended to plumb the discharge line independent and separate of the engine’s fuel
return line back to the tank. If the return line from the engine and the discharge of the STS 7030 have to
be combined in any way, adequate valves should be installed to prevent any possible interference with
safe engine operation.
Note: If any of the STS 7030 system’s fuel lines are used in combination with the engine’s fuel
system, the STS 7030 should be disabled during engine operation (use the provided
“remote pump shut down” feature as shown in the electrical drawing and described
above).
12
PRIMING THE SYSTEM
The pump supplied with the STS 7030 is NOT automatically self-priming and must not be run dry.
! WARNING ! If the pump is allowed to run without fuel, pump damage will occur.
The pump head of the STS 7030 unit is shipped from the factory filled with Diesel #2 to facilitate initial
lubrication. This will not eliminate the necessity to prime the complete system. The STS 7030 is primed by
using the externally installed priming tee (not provided) on the suction side of the system. Also the
suction line must be completely filled with fuel prior to the initial system start-up.
PRIMING PROCEDURE:
1. Ensure the pump is filled with #2 Diesel fuel.
2. Ensure that the inlet ball valve is in the open and the outlet ball valve is in the closed position.
3. Slightly open the manual air vent valve (bleed screw) located just below the pressure gauge on
the primary filter(position #14 – page 5).
4. Open the externally installed priming tee (located at the highest point of the suction plumbing),
fill the line with fuel until fuel escapes from bleed screw (manual air vent), close the manual air
vent, continue filling until all air is bled from the plumbing lines and system, close the priming tee.
(for tanks situated on a lower level than the STS 7030, it is recommended that a foot valve is
installed at the fuel tank to hold the fuel column).
5. Make sure to completely fill suction line to its highest point with fuel (no trapped air), in particular
when the suction line exits the tank top and the STS 7030 is located below that level.
6. Open the outlet ball valve and ensure the inlet ball valve is also in open position.
7. Switch on the pump and observe fuel flow.
The system is equipped with a vacuum gauge on the input side of the pump. The gauge should read 0 to
11" HG vacuum maximum under normal conditions. Vacuum gauge readings reaching 12" HG vacuum
indicate excessive debris in the Nexus Y strainer (or a flow restriction or too high suction height and
therefore pressure drop in the suction line) and will result in pump shutdown and activate the alarm
“HIGH VACUUM ALARM”.
Note: 12" HG vacuum = clogged strainer or suction line flow restriction / excessive lift.
The system’s pressure gauge on the secondary filter should show 25 PSI maximum pressure under
normal conditions (.433 PSI = 1' vertical head pressure). Pressure gauge readings in excess of 25 PSI
pressure indicate excessive filter clogging, or fuel line restrictions and/or friction.
Differential pressure over 25 PSI indicates filter clogging (“HIGH PRESSURE ALARM” indicator) and will
automatically shut down the pump.
The pressure relief valve has a 40-45 PSI set point. Pump discharge pressure in excess of 40-45 PSI will
cause the pressure relief valve to open and vent fuel back to the fuel transfer pump inlet side.
TOUCH-SCREEN CONTROLLER - ALARM FEATURES
The STS 7030 is equipped with an AXI INTERNATIONAL Touch-Screen Controller. System and alarm
status are displayed on the industrial control panel (on the door) via indicator lights and on the text
display directly on the controller.
14
INITIAL START-UP / COMMISSIONING CHECKLIST
FLOW SWITCH SETTING / ADJUSTMENT (“NO FLOW ALARM”)
Note: Flow switch needs to be adjusted to actual flow rate for proper system operation.
Please make sure system is properly primed and check when pump running for a steady stream of fuel
without air bubbles in the mechanical flow meter (indicator) inside the STS 7030 enclosure. If the “NO
FLOW ALARM” alarm light is blinking (and after 10 seconds illuminate continuously as the pump is turned
off) the flow switch located on the side of the mechanical flow meter needs to be adjusted to the
actual flow rate.
This can be easily done by sliding the black switch (with lead attached) located on the side of the sight
glass carefully up or down (while pump is running) and lining up the flow switch with the indicator ring
inside the sight tube of the flow meter showing the actual flow rate. For further information please see
enclosed instruction sheet.
You can reset the alarm by pushing the “ALARM RESET” button located on the control panel.
GAUGE VENTING / ACCURACY
After shipment, pointer of gauges may not rest at zero due to internal case pressure buildup caused by
temperature variations. Accuracy may be significantly reduced. To restore gauge to operating
condition, move yellow lever of fill plug to the ”open” position or remove small plug from top of
gauge and leave open.
INITIAL TEST PROCEDURE
o With breakers and power turned on and pump running check all alarms for proper operation:
1. Manually raise float switch located in drip/spill tray. Pump should immediately turn off and “LEAK
DETECTION” should illuminate. Reset alarm by pushing the “RESET ALARM” button on the control
panel.
2. Slowly partially close inlet ball valve. At 12”HG pump should turn off and “HIGH VACUUM ALARM”
should illuminate. Open inlet ball valve again. Reset alarm by pushing the “RESET ALARM” button.
3. Slide the flow switch located on the side of the mechanical flow meter slightly upwards away
from the flow indicator inside the sight tube (mark original position before doing so). The “NO
FLOW ALARM” indicator should start blinking for 10 seconds and then illuminate constantly as the
pump is turned off. Slide flow switch back into original position and reset alarm by pushing the
“RESET ALARM” button.
Note: If any of the above described alarm test procedures fail or if any alarm trip value
deviates immediately contact AXI International.

FUEL LINE LEAK
If fuel is detected in the spill / drip tray, the float switch will activate the fuel leak alarm, illuminating the
“LEAK DETECTION” indicator. The pump motor will shut off and remain locked out of operation until the
leak has been corrected and the “ALARM RESET” button has been pushed. Before removing the spilled
fuel from the basin, turn the key switch to the “OFF” position. Always make sure to find the cause of the
leakage and correct it. After removing the spilled fuel, allowing the leak switch to return to its normal
position, the key switch can be returned to the “AUTO” or “RUN” mode.
Note: Disposal of fuel and associated waste should be done in accordance with Federal, State
and Local regulations.
STABILIZING AND OPTIMIZING FUEL QUALITY
We recommend treating the fuel with the AXI INTERNATIONAL Fuel Catalyst (AFC-705). This will
enhance and accelerate the tank cleaning process by breaking down and dissolving existing tank sludge.
AFC-705 will decontaminate compartments of the tank that are out of reach of the suction line.
18
Depending on the condition of the fuel and the amount of sludge build-up, it is recommended to initially
use a double dose of one to twenty-five hundred (1:2500) instead of one to five thousand (1:5000) This
has proven to be essential in accelerating the tank cleaning process. AFC-705 contains detergent,
surfactant, dispersant, corrosion inhibitor, lubricity enhancer and combustion catalyst. It does not contain
biocides. AFC-705 should always be used periodically in particular to stabilize fuel that is stored for longer
periods of time.
Note: In cases of severe tank contaminant build-up (sludge) and high water level in bottom, it
is recommended to clean the tank (vacuum bottom) and polish the fuel before initial
use of an STS system.
MAINTENANCE
! IMPORTANT ! It is recommended that only qualified, 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 fluids have been drained.
PREVENTATIVE MAINTENANCE
The STS 7030 Automatic Fuel Filtration System should be visually inspected and tested a minimum of
every six months according to the procedure below during light duty cycles. Monthly inspections are
recommended for systems that are being used in excess of an average of 8 hours day and five days a week.
