OWNERS MANUAL

These instructions will help you operate and maintain your pump. This owner's manual covers the EZ-8RV and EZ-8RVS, 12-volt electric gear pumps. This manual covers models with manual nozzle.


Notice: This pump is not intended to be used with an automatic nozzle.

An automatic bypass valve prevents pressure build up when the pump is on with the nozzle closed.

To avoid motor damage, do not run the pump more than 5 minutes with the nozzle closed. The rated duty cycle of this pump is 15 minutes ON and 30 minutes OFF.

Allow the pump to cool for 30 minutes.


FUEL TYPE

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 12-volt DC auto­motive electrical system.

The pump is designed to operate with 12-volts DC 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 vehicle charging system that will affect system voltage.

Do not leave the system running without fluids. "Dry running" can damage the pump. If the system fails to deliver fuel after 15 to 20 seconds, turn the system off and refer to the Troubleshooting Section.

Do not pump the tank completely dry, as contaminants from the bottom of the tank may enter the pump.


SAFETY INSTRUCTIONS

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 in this manual.


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 coverplates are removed.


INSTALLATION

This pump is designed to self-prime with dry gears.

Make sure all threaded fuel connections are wrapped with three to four turns of Teflon® tape or a pipe thread sealant approved for use with petroleum fuels.

Clean the tank interior of all dirt and debris.

Make sure the tank is vented. A vent cap rated at 3 psi or less is recommended.

Suction line design and size is important for optimum pump performance. GPI requires suction line to be 3/8" miminum diameter.

Pump must be mounted within the clearance lines of the vehicle and protected from road impact damage.


Install Electrical Connections

A grounding connection is provided. It is identified as a green colored binding head screw in the electrical cavity. Connect these pumps only to a 12-volt DC power source.

Do not attempt connection to a 24-volt DC, 115-volt AC or 230-volt AC power source.

For installation in unclassified areas, a flexible power cord, fuse and strain relief grip should 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 coverplate. 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 in. (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 cord wires. Insert the power cord through the 1/2 inch NPT connection on the back of the pump. Using wire nuts, connect black wire to black and red wire to 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 coverplate 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.


 !!! WARNING !!!

Pump must have circuit protection per ANSI/RVIA 12. A 20-amp slow-blow fuse is a minimum requirement to protect the motor and power cord. Install fuse in the red wire of the power cord adjacent to the battery. Connect the fuse to the positive (ungrounded) side of battery. Connect black wire to the negative (grounded) side of battery.


!!! DANGER !!!

If 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. Install Hose and Nozzle After sealing threads, tighten the hose into the pump outlet and the nozzle on the hose. Failure to follow these wiring instructions may result in death or serious injury from shock, fire or explosion.



OPERATION

ALWAYS FOLLOW SAFETY INSTRUCTIONS WHEN OPERAT­ING THIS EQUIPMENT.

Before each use, repair leaks around seals or connections. Make sure hoses are in good condition and connections are tight.

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.

To Dispense Fuel

Depending on the model, turn pump on by activating the power circuit on the RV or by lifting up on the switch lever. Insert the nozzle into the receiving tank and squeeze the handle to start fuel flow. When done, release the nozzle handle and turn off the pump. 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 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 more than 5 minutes with the nozzle closed. After running the pump for a maximum of 15 minutes, allow it to cool for 30 minutes.


Auxiliary Temperature-Limiting Device

The motor is provided with an internal auxiliary temperature-lim­iting device. Excessive motor heat can trip the device. It resets automatically after the motor has cooled.


MAINTENANCE

This pump is designed for minimum maintenance. Motor bear­ings are sealed and require no lubrication. Inspect the pump and components regularly for fuel leaks and make sure the hose and power cord are in good condition. Keep the pump exterior clean to help identify leaks.

Do not use this pump for water, chemicals or herbicides. Dispens­ing any fluid other than that listed in this manual will damage the pump. Use of the pump with unauthorized fluids will void the warranty.






TROUBLESHOOTING

ALWAYS DISCONNECT POWER BEFORE REPAIRING OR SER­VICING THE PUMP.

NEVER APPLY POWER TO THE SYSTEM WHEN ANY COVERPLATE IS REMOVED.


 A.   MOTOR DOES NOT RUN

1.    Check electrical connection. Inspect for defective wiring or improper electrical connections. Repair as necessary.
