There are inherent dangers wherever flammable 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 filters must be approved for use with fuel
transfer systems. The flow of fuel through a hose and
nozzle can generate static electrical charges and dan-
gerous sparking can result in fire or explosion. Hoses
and nozzles must be statically-grounded.
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 flammable 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.

WARNING
Coverplates protect the operator from moving
parts. Never operate the pump without coverplates
in place. Never apply electric power to the pump
without coverplates in place. Always disconnect
power before repairing or servicing.
Your pump is designed for use only with thin viscosity
petroleum fuels such as 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 fluids other than those for which
it was designed. Using the pump with other fuels can
damage components and void the warranty.
All threaded fuel connections must be sealed with thread
tape or a pipe thread sealing compound approved for
use with petroleum fuels.
Your pump must be mounted on a vented tank. If the
tank is not vented, contact your GPI distributor for the
correct vent cap.
This pump has a built-in check valve to keep the pump
primed. No additional check valve is required on suction
pipes shorter than 15 feet (4.6 m). Make sure any check
valves or foot valves used are equipped with proper
pressure relief valves.
Your pump is designed to mount directly to a standard
2-inch female tank fitting. For the suction pipe, a 1-inch
galvanized steel pipe cut to length and threaded on one
end may be used. Suction pipe should extend to within
3 inches (76.2 mm) of tank bottom. Apply thread tape to
the suction pipe thread and securely tighten the suction
pipe to the pump inlet port.

DANGER
Pump must be installed by a licensed electrician
in accordance with national, state and local electri-
cal codes. Rigid conduit must be used to install
wiring. Installation must conform to National Fire
Prevention Association (NFPA) codes 30A and 70.
Other codes may apply.
Failure to follow these wiring instructions may
result in death or serious injury from shock, fire
or explosion.
The pump must be properly grounded to avoid
personal injury. Operating an ungrounded or im-
properly grounded pump may result in death due
to electrical shock, fire or explosion.
Electrical wiring and connections must be made only by
a licensed electrician in accordance with national, state
and local electrical codes regarding Class 1, Division 1,
Group D locations. Other codes may apply.
Thread for the conduit connection at the pump electrical
box is 1/2 inch FNPT.
A standard 15-amp breaker is recommended.
This pump is equipped with an auxiliary AC accessory
lead. The third wire (purple) is to be used to energize
a control circuit that operates a device such as a signal
light or a solenoid operated valve. Maximum amp draw
on the control circuit is 1 amp. If you do not need this
feature, ensure that the wire is insulated and enclosed
within the electrical cavity of the pump.
CAUTION
Connect pump to the proper voltage source.
M-3260 series pumps are designed to operate on
230 VAC, 50 or 60 Hz. Connection to improper volt-
age will damage pump.
