SFM 1080
Solar Powered Fuel Maintenance System
The SFM Series Solar Powered Intelligent Fuel Maintenance System is designed to optimize and maintain diesel fuel
indefinitely by removing particulate and water in stored fuel. Powered by a solar panel and 12V DC battery, this innovative
process stabilizes diesel and bio-fuels, eliminates microbial contamination, and ensures clean reliable fuel at all times. The
SFM Series Solar Powered Intelligent Fuel Maintenance System is ideal for stored fuel in remote locations where grid power
isn’t readily available.
SFM Series Systems are designed around a self-priming 80
GPH nickel-plated brass gear pump. Quality filtration
components are connected using corrosion-resistant
Stainless Steel plumbing. A pressure gauge is installed on
the filter housing to ensure optimal filter usage by showing
remaining filter life. Available filter elements include stainless
steel mesh filter, particulate, and water block elements.
Fuel has a limited shelf-life, and even “fresh fuel” could
contain water, sediment, and microbes upon delivery. With
the extreme conditions stored fuel is commonly enduring, it is
critical to ensure fuel is maintained on a regular basis.
SFM Systems reverse fuel deterioration while
decontaminating, cleaning, and optimizing the fuel to ultra
clean levels for ultimate reliability.

Installation
INSTALLATION
!IMPORTANT! It is recommended that only qualied, experienced personnel, familiar with this type of
equipment, who have read and understood all the instructions in this manual should install, operate, and
maintain the system.
Mounting
SFM 1080
The SFM 1080 is a totally enclosed system, and should be permanently mounted on a hard, level surface. This weatherproof
unit is designed for well-ventilated outdoor use within specied temperature range, and should be located as close to the
tank as possible.
Solar Panel
The solar panel that powers the SFM 1080 should be permanentaly mounted on a hard surface or supported bracket. The
panel should be installed in a location that is exposed to direct sunlight for the majority of the day. Nearby obstructions may
limit direct sunlight, which can inhibit optimal power/charging delivery to the battery. The optimal tilt angle for the solar panel
varies by geographical location. Contact your representative for information relating to your location.
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.
The SFM 1080 should be grounded 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.
Note: Wiring and electrical installation must be in accordance with all applicable federal, state, and local rules, laws,
standards, and regulations.

REV03121080011217
OVERVIEW
Plumbing
Use proper quality, approved fuel line materials with at least 1/2” inner diameter on the suction side from the tank and at least
1/2” inner diameter on the return/discharge side back to the tank.
Note: Do not put any stress on plumbing of SFM 1080, and use a backing wrench when connecting the external plumbing.
The pick up tube/line(s) should originate from the lowest point of the tank to ensure all water is removed, 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 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 on some installations to prevent back ow pressure.
Ball valves should be installed on both the inlet and the outlet of the system to isolate the system during servicing.
Anti-Siphon or other external plumbing devices may be required – please check local regulations/code.
The system capabilities are maximum 12” HG pump inlet vacuum. Keep suction plumbing short and straight with as little as
possible restrictions. For continuous optimal performance, make sure suction and discharge lines are free and that nothing
is blocking the ow of fuel and that the suction line always stays primed.
Note: Plumbing installation must be in accordance with all applicable federal, state, and local rules, laws, standards, and
regulations.

OVERVIEW
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 SFM 1080 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 SFM
1080 have to be combined in any way, adequate valves should be installed to prevent any possible interference with safe
engine operation.

OVERVIEW
Priming the System
PRIMING
The pump supplied with the SFM 1080 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 SFM 1080 unit is shipped from the factory lled with #2 Diesel to facilitate initial lubrication. This will
not eliminate the necessity to prime the complete system. The SFM 1080 is primed by using the externally installed priming
tee (not provided) on the suction side of the system. Also, the primary lter, as well as the suction line, has to be completely
lled with fuel prior to the initial system start-up.
Priming Procedure
1. Ensure the pump is lled 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. Open the externally installed priming tee (located at the highest point of the suction plumbing), ll the line with fuel.
4. Make sure to completely ll suction line to its highest point with fuel (no trapped air), in particular when the suction line
exits the tank top and the SFM 1080 is located below that level
5. Open the outlet ball valve and ensure the inlet ball valve is also in open position
6. Switch on the pump and observe fuel ow
The system is equipped with a vacuum switch on the input side of the pump. When the pump inlet vacuum reaches 12”
HG, the system will shutdown and activate the high vacuum alarm. This indicates excessive debris in the strainer (or a ow
restriction, or too high suction height and therefore pressure drop in the suction line).
Note: 12” HG vacuum = clogged primary lter or suction line ow restriction / excessive lift.
The system’s pressure gauge on the ne lter should show 15 PSI maximum pressure under normal conditions (.433 PSI =
1’ vertical head pressure). Pressure gauge readings in excess of 15 PSI indicate excessive lter, or fuel line restrictions and/
or friction and will trigger the high-pressure alarm, automatically shutting down the pump.
