GPI EZ-8 12V DC, 8 Fuel Trandfer Pump Owner’s Manual
GENERAL INFORMATION
These instructions will help you operate and maintain your pump. This owner’s
manual covers the EZ-8, 12-Volt electric gear pump with manual nozzle.
Notice: This pump is not intended to be used with an automatic nozzle.
WARNING This product shall not be used for pumping fuel or other liquids into aircraft.
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.
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 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 coverplates 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.
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 and bond the suction pipe top and bottom as necessary. Thread the
suction pipe into the inlet fitting and tighten snugly. Trim the suction pipe
as necessary to leave approximately 1/2 in. (1.2 cm) clearance from the bottom
of the tank. Clean the tank interior of all dirt and debris. Insert the
suction pipe into the tank opening. Tighten the pump into the tank opening
until snug. Do not cross thread.
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 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, 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 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
A 20-amp fuse is provided to protect the motor and power cord. Install fuse in
the red wire of the power cord adjacent to the battery. Connect the red wire
of the fuse to the positive (ungrounded) side of the battery. Connect black
wire to the negative (grounded) side of the 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.
Failure to follow these wiring instructions may result in death or serious
injury from shock, fire or explosion.
Install Hose and Nozzle
After sealing 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.
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. Tighten loose tank lids regularly.
To Dispense Fuel
Turn on the pump by removing the nozzle from the 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 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 temperaturelimiting 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.
