Mechanical Connections - GPI M-3260 Serie Guía De Operación

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 con-
cern and requires extreme care in the installation and op-
eration of your entire fuel transfer system.
Additional components such as meters, automatic nozzles
and filters must be approved for use with fuel transfer sys-
tems. The flow of fuel through a hose and nozzle can gener-
ate static electrical charges and dangerous sparking can re-
sult in fire or explosion. Hoses and nozzles must be stati-
cally-grounded.
It is your responsibility to:
• Know and follow applicable national, state and local
safety codes pertaining to installing and operating elec-
trical equipment for use with flammable 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.
INSTALLATION

Mechanical Connections

WA R N I N G
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 pe-
troleum 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 4.6 meters (15 feet). Make sure any check
valves or foot valves used are equipped with proper pres-
sure relief valves.

Your pump is designed to mount directly to a standard
2-inch female tank fitting. For the suction pipe, a 1-inch gal-
vanized steel pipe cut to length and threaded on one end
may be used. Suction pipe should extend to within 7.6 cm
(3 inches) of tank bottom. Apply thread tape to the suction
pipe thread and securely tighten the suction pipe to the pump
inlet port.

DA N G E R
Pump must be installed by a licensed electrician in ac-
cordance with national, state and local electrical codes.
Rigid conduit must be used to install wiring. Installa-
tion must conform to National Fire Prevention Asso-
ciation (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 improperly
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 so-
lenoid operated valve. Maximum amp draw on the control
circuit is 1 amp. If you do not need this feature, insure that
the wire is insulated and enclosed within the electrical cav-
ity of the pump.
CAU TI O N
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 voltage will damage
pump.
