Product Manual

2 Rev. D 921422-18
GENERAL INFORMATION
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 electric gear pump models
M-150S, M-180S and M-240S.
Models M-150S and M-180S should be connected to a
12-volt DC power source.
Model M-240S should 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 E15), 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 designed. To do so may damage
pump components and will void the warranty.
This pump is designed to operate on a typical DC automo-
tive 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 af-
fect system voltage.
Do not leave the system running without 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. Obey all safety messages that follow
this symbol to avoid possible injury or death.
DANGER
DANGER indicates a haz-
ardous situation which, if
not avoided, will result in
death or serious injury.
WARNING
WARNING indicates a
hazardous situation which,
if not avoided, could result
in death or serious injury.
CAUTION
CAUTION indicates a haz-
ardous situation which, if
not avoided, may result in
minor or moderate injury.
It is your responsibility to:
• know and follow applicable national, state, and local
safety codes pertaining to installing and operating
electrical equipment for use with ammable liquids.
• know and follow all safety precautions when handling
petroleum fuels.
• ensure that all equipment operators have access to
adequate instructions concerning safe operating and
maintenance procedures.
Observe all safety precautions concerning safe handling
of petroleum fuels.
To ensure safe operation, all fuel transfer systems
must be properly 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 oper-
ating 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 electri-
cal shock, use extra care when connecting the pump
to power.
Avoid prolonged skin contact with petroleum fuels. Use
protective goggles, gloves and aprons in case of splash-
ing 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.
