Product Manual

2
The purpose of this manual is to assist you in installing, operating
and maintaining your GPI pump. This manual covers 12- and
24-volt DC models M-3025 and M-3425.
Models M-3025 and M-3025CB must be connected to a 12-volt
DC power source only.
Models M-3425 and M-3425CS must be connected to a 24-volt
power source only.
Do not attempt connection of any pump to a 115-volt AC or
230-volt AC power source.
An automatic bypass valve prevents pressure build up when
the pump is on with the nozzle closed. To avoid damage,
do not run the pump more than 10 minutes with the nozzle
closed.
The duty cycle of this pump is 30 minutes ON and 30 minutes
OFF. Allow the pump to cool for 30 minutes.
This pump is designed for use only with gasoline (up to 15%
alcohol blends such as E-15), diesel fuel (up to 20% biodiesel
blends such as B20) and kerosene. Do not use this pump for
dispensing any uids other than those for which it was de-
signed. To do so may damage pump components and will void
the warranty.
This pump is designed to operate on a typical DC automotive
electrical system. The pump is designed to operate with the
appropriate DC voltage at the motor leads and the ratings are
determined at this voltage. Performance may vary due to length
of power cord, battery condition or output from the vehicle
charging system that will affect system voltage.
Do not leave the system running with uids. “Dry running” can
damage the pump.
Do not pump the tank completely dry, as contaminants from the
bottom of the tank may enter the pump.
SAFETY INSTRUCTIONS
The following safety alert symbols are used
in this manual.
DANGER indicates a haz-
ardous situation which, if
not avoided, will result in
death or serious injury.
WARNING indicates a haz-
ardous situation which, if
not avoided, could result
in death or serious injury.
CAUTION indicates a haz-
ardous situation which, if
not avoided, may result in
minor or moderate injury.
There are inherent dangers wherever ammable fuel and AC
electrical sources are in close proximity.
Static electricity as a source of sparking is always a concern
and requires extreme care in the installation and operation of
your entire fuel transfer system.
Additional components such as meters, automatic nozzles
and lters must be listed for use with fuel transfer systems.
The ow of fuel through a hose and nozzle can generate static
electrical charges and dangerous sparking can result in re or
explosion. Hoses and nozzles must be electrically conductive
and bonded to ground.
It is your responsibility to:
• Know and follow applicable national, state and local safety
codes pertaining to installing and operating electrical equip-
ment for use with ammable liquids.
• Know and follow all safety precautions when handling
petroleum fuels.
• Ensure that all equipment operators have access to ad-
equate instructions concerning safe operating and main-
tenance procedures.
Observe all safety precautions concerning safe handling of
petroleum fuels.
To ensure safe operation, all fuel transfer systems must be prop-
erly grounded. Proper grounding means a continuous metal-to-
metal contact from one component to the next, including tank,
bung, pump, meter, lter, hose and nozzle. Care should be taken
to ensure proper grounding during initial installation and after
any service or repair procedures. For your safety, please take a
moment to review the warnings below.
To prevent physical injury, observe precautions against re or
explosion when dispensing fuel. Do not operate the system in
the presence of any source of ignition including running or hot
engines, lighted cigarettes, or gas or electric heaters.
Observe precautions against electrical shock when operating
the system. Serious or fatal shock can result from operating
electrical equipment in damp or wet locations.
Inspect external pump wiring regularly to make sure it is correctly
attached to the battery. To avoid electrical shock, use extra care
when connecting the pump to power.
Avoid prolonged skin contact with petroleum fuels. Use protec-
tive goggles, gloves and aprons in case of splashing or spills.
Change saturated clothing and wash skin promptly with soap
and water.
Observe precautions against electrical shock when servicing the
pump. Always disconnect power before repairing or servicing.
Never apply electrical power to the system when any of the
coverplates are removed.
If using solvent to clean pump components or tank, observe
the solvent manufacturer’s recommendations for safe use and
disposal.
