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 fluids 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 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 without fluids. “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 DANGER indicates a hazardous 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 hazardous 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 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.

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, filter, 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 fire 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 protective 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 cover plates are removed.

If using solvent to clean pump components or tank, observe the solvent manufacturer’s recommendations for safe use and disposal.

INSTALLATION

This pump is designed to self-prime with dry gears. Expect suction lift as follows:

Manual Nozzle:
5.5 feet (1.7 m) with diesel
6.7 feet (2.1 m) with gasoline

Automatic Nozzle:
4.8 feet (1.5 m) with diesel
5.8 feet (1.8 m) with gasoline

If you require a greater initial prime height, coat the gears with fluid by removing the plug on the top of the pump and pour a small quantity of motor oil into the gear cavity. Replace the plug and try again. A foot valve with pressure relief may be needed to maintain prime. Make sure all threaded fuel connections are wrapped with three to four turns of thread tape or a pipe thread sealant approved for use with petroleum fuels.

Install Bung Adapter and Suction Pipe

• Tighten the bung adapter snugly into the fuel tank.
• Place the union ring gasket into the inlet fitting on the bottom of the pump.
• Thread the suction pipe into the inlet fitting and tighten until snug.

Install Pump on Tank

• Clean the tank interior of all dirt and foreign material.
• Extend the suction pipe to its full length and insert into the tank opening. (Figure 1)
• Place the pump on the bung adapter and tighten the union ring securely with a pipe wrench. Make sure the union ring is not cross-threaded.
• To prevent pressure build-up and possible fuel leaks through the nozzle, make sure the tank is vented. A vent cap rated at 3 psi or less is recommended.

Install Electrical Connections
A grounding connection is provided. It is identified as a green coloured binding head screw in the electrical cavity.

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 DC power source.

Do not attempt connection of any pump to a 115-volt AC or 230-volt AC power source.

For installation in unclassified areas, the supplied power cord, fuse and strain relief grip may be used.

NOTE: These components have not been evaluated as part of the UL Listed Equipment and are not intended for use in a Hazardous (Classified) Location.

To install the power cord, remove the electrical cover plate. (Figure 2)

If necessary, trim the power cord to the desired length. Strip 3 to 4 inches (7.5 to 10 cm) of outer insulation from the power cord end. Then strip 1/2 inch (1.3 cm) of insulation from the power cord wires.

Slide the strain relief grip onto the power cord so that the threaded end of the strain relief grip faces the stripped power wires. (Figure 3)

Insert the power cord through the 1/2 inch NPT connection on the back of the pump. (Figure 4) Using wire nuts, connect the black wire to the black wire and the red wire to the red in the pump’s electrical cavity. Position the wires inside the electrical cavity and tighten the strain relief grip securely. Make sure surfaces are clean. Install the cover plate and tighten securely.

WARNING
Carefully route the power cord to the battery, protecting the power cord from hot surfaces, sharp edges or anything that could damage the power cord, resulting in a short circuit. A fuse is provided to protect the power cord and motor. Install fuse in the red wire of the power cord as close as possible to the battery. Connect the red wire of the fuse to the positive (ungrounded) side of battery. Connect black wire to the negative (grounded) side of the battery. Failure to follow these instructions could result in death, serious injury or loss of equipment due to short circuit, fire or explosion.

DANGER
If the pump is to be installed in a Hazardous (Classified) location, it must be installed by a licensed electrician and conform to National Fire Protection Association (NFPA) codes 30 and 70. You as the owner, are responsible for seeing that the installation and operation of your pump complies with NFPA codes as well as any applicable state and local codes. Rigid conduit must be used to install wiring. Note that the lead wires are factory-sealed isolating the motor from the junction box. Failure to follow these wiring instructions may result in death or serious injury from shock, fire or explosion.

Install Hose and Nozzle
After sealing the threads, tighten the hose into the pump outlet and the nozzle on the hose. The nozzle can be placed in the nozzle holder only when the pump is off. The nozzle holder allows the pump to be locked when the nuzzled is in place.

OPERATION

ALWAYS FOLLOW SAFETY PRECAUTIONS WHEN OPERATING THIS EQUIPMENT. REVIEW THE SAFETY INSTRUCTIONS. Before each use, repair leaks around seals or connections. Make sure hoses are in good condition and connections are tight. Make sure the work area is dry. MAKE SURE THE PUMP IS PROPERLY GROUNDED. Repair any corroded or damaged wiring before use. Ensure the tank contains enough fuel. Make sure the fuel is not contaminated with debris.

Dispense Fuel
Turn the pump on by removing the nozzle from its holder and pushing up the switch lever. Insert the nozzle into the receiving tank and squeeze the handle to start fuel flow. When done, release the nozzle handle, turn the pump off, and return the nozzle to its holder.

This pump is designed to be self-priming. If fuel is not delivered within 15 to 20 seconds, turn the pump off and refer to the priming information in the Troubleshooting Section.

An automatic bypass valve prevents pressure build-up when the pump is on with the nozzle closed. To avoid pump damage, do not run the pump for more than 10 minutes with the nozzle closed.
