WARNING
Coverplates protect the operator from moving parts.
Never operate the pump without coverplates in place.
Never apply electric power to the pump without cover-
plates in place. Always disconnect power before repair-
ing or servicing.
Your pump is designed for use only with diesel fuel. 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 diesel fuel.
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 pressure relief valves.
Your pump is designed to mount directly to a standard 2-inch
female tank fitting. For the suction pipe, a 1-1/4-inch galva-
nized 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.

Electrical Connections

DANGER
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. 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 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.
A standard 15-amp breaker is recommended.
2
This pump is equipped with an auxiliary AC accessory lead.
The third wire (red) 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, insure that the wire is
insulated and enclosed within the electrical cavity of the pump.
CAUTION
Connect pump to the proper voltage source. M-3295
series pumps are designed to operate on 230 VAC, 60/50
HZ. Connection to improper voltage will damage pump.
Pump is set at factory for high voltage applications
(230-volt). See wiring diagram located inside electrical
coverplate.

Wiring Details

1. Remove electrical coverplate (Figure 1). Install conduit
and cable from switchbox to pump electrical box. Use
only code specified 2-conductor cable with ground wire.
2. Attach ground wire using the green ground screw located
inside the electrical box (Figure 2). Connect the power
cable to the pump wiring per the wiring diagram located
inside the electrical coverplate. Secure with wire nuts.
3. Position wires inside the electrical box. Replace electrical
coverplate with all seven (7) screws and tighten securely.
