this symbol to avoid possible injury or death.
DANGER DANGER indicates an
imminently hazardous
situation which, if not avoid-
ed, will result in death or
serious injury.
WARNING WARNING indicates
a potentially hazardous
situation which, if not avoid-
ed, could result in death or
serious injury.
CAUTION CAUTION indicates
a potentially hazardous
situation which, if not avoid-
ed, may result in minor or

property damage.
There are inherent dangers wherever ammable fuel and
AC electrical sources are in close proximity.
Static electricity as a source of sparking is always a
concern and requires extreme care in the installation and
operation of your entire fuel transfer system.
Additional components such as meters, automatic nozzles
and lters must be listed for use with fuel transfer systems.
The ow of fuel through a hose and nozzle can generate
static electrical charges and dangerous sparking can
result in re or explosion. Hoses and nozzles must be
electrically conductive and bonded to ground.
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 ammable 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.
Appropriate hose, nozzle and suction pipe not
included. Items must meet NFPA 407 guidelines.
For ground-based refueling only. Do not use in or on the aircraft.
For use with aviation gasoline (AVGAS 100LL) and kerosene grade
(JET A).
User should consult NFPA 407 Standard for Aircraft Fuel Servicing
for safety requirements during ground fuel servicing of aircraft
using liquid petroleum fuels. This product has no actual or implied
compliance with this standard.
WARNING
INSTALLATION
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.
WARNING
Mechanical Connections
All threaded fuel connections must be sealed with thread
tape or a pipe thread sealing compound approved for
use with petroleum fuels and tightened securely to pre-
vent leakage.
Your pump must be mounted on a vented tank. If the
tank is not vented, contact your GPRO™ 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 suc-
tion pipes shorter than 15 feet (4.6 meters). 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
in. female tank tting. For the suction pipe, a 1 in. pipe
cut to length and threaded on one end may be used.
Suction pipe should extend to within 3 inches of tank
bottom. Apply thread tape to the suction pipe thread and
securely tighten the suction pipe to the tank adapter. Once
suction pipe is attached to tank adapter, insert suction
pipe into tank and tighten tank adapter to tank tting.
Install Nozzle Hanger
Attention:The nozzle hanger for your pump was removed
before shipping to protect against damage.
To reinstall the nozzle hanger follow the steps below.
1. Remove the two (2) 1/4"-20 x 1/2" bolts from the
switch coverplate.
2. Place the nozzle cover on the switch coverplate and
align holes.
3. Insert the two (2) 1/4"-20 x 1/2" bolts through the
nozzle cover and thread into the switch coverplate.
Torque bolts to 45-60 in/lb (Figure 1).

FIGURE 1
Install Appropriate Hose and Nozzle
The hose and nozzle is not included. Install hose and
nozzle per NFPA 407.
All threaded fuel connections must be sealed with thread
tape or a pipe thread sealing compound approved for
use with petroleum fuels.
Electrical Connections
Pump 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.
Failure to follow these wiring instructions may result in death or
serious injury from shock, re 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, re or explosion.
DANGER
Electrical wiring and connections must be made only by
a licensed electrician in accordance with national, state
and local electrical codes regarding Class I, Division 1,
Group D locations. Other codes may apply.
Thread for the conduit connection at the pump electrical
box is 1/2 in. FNPT.
A standard 15-amp breaker is recommended.
This pump is equipped with an auxiliary AC accessory
lead. The third wire (brown for 115-volt system) is to be
used to energize a control circuit that operates a device
such as a signal light or a solenoid operated valve. Maxi-
mum amp draw on the control circuit is 1 amp. If you do
not need this feature, ensure that the wire is insulated
and enclosed within the electrical cavity of the pump.
Connect pump to the proper voltage source. PRO20-115 Pumps
are designed to operate on 115 VAC, 60 Hz.
CAUTION
Wiring Details
1. Remove electrical coverplate and O-ring (Figure 2).
Install conduit and cable from switchbox to pump elec-
trical box. Wiring must be in accordance with Class
I, Division 1 requirements in the applicable national
electrical code. Note that the lead wires are factory-
sealed isolating the motor from the junction box.
FIGURE 2
2. Attach ground wire using the green ground screw lo-
cated inside the electrical box (Figure 3). The external
bonding connection is only a supplemental bonding
connection where local authorities permit or require
such a connection. For 115-volt system connect the
power cable to the black and white pump wires and the
control circuit (if required) to the brown wire. Secure
with wire nuts. Refer to appropriate wiring diagram
on Page 4.

OPERATION
To prevent physical injury, observe precautions against re or
explosion when dispensing fuel. Do not operate the dispenser in
the presence of any source of ignition including running or hot
engines, lighted cigarettes, or gas or electric heaters.
DANGER
Observe precautions against electrical shock when operating the
system. Serious or fatal shock can result from operating electrical
equipment in damp or wet locations.
WARNING
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.
CAUTION
To dispense fuel (for pumps with nozzle
hanger):
1. Remove the nozzle from the holder. Turn the pump
on by pulling the switch lever down.
2. Insert the nozzle into the receiving tank and squeeze
the handle to dispense fuel.
3. After dispensing fuel, push the switch lever up to turn the
pump off and return the nozzle to the holder. The nozzle
may be locked in place to prevent unauthorized use.
The pump contains an automatic bypass valve to prevent
pressure buildup when the pump is on but the nozzle
is closed. Do not leave the pump on for more than 10
minutes with the nozzle closed.
Never leave the pump running without uid. Dry running
can damage the pump components.
The pump has a duty cycle of 30 minutes ON and 30
minutes OFF. Do not overheat. Allow the motor to cool
the same length of time it was in operation.
If the pump becomes too hot, an internal temperature-limiting
device will automatically shut the motor off and prevent operation
until it cools. The fuel strainer and check valve assembly
should be cleaned on a regular basis or if low ow rate
is noticed.
Always turn the pump off if the temperature-limiting device trips.
If left on, the pump will automatically reset when cool and start
pumping.
CAUTION
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 condi-
tion. Keep the pump exterior clean to help identify leaks.
Do not use this pump for water, chemicals or herbicides.
Dispensing any uid other than those listed in this manual
will damage the pump. Use of the pump with unauthor-
ized uids will void the warranty.
To Clean or Replace Strainer
All pump models have an inlet strainer. If owrate is
reduced, clean or replace strainer.
Turn the pump off and disconnect from power. Remove
and clean the strainer with a soft-bristled brush and
solvent. If the strainer is very dirty, compressed air may
be used. If damaged, replace the strainer.
Replace components making sure that they are seated
and fasteners are tightened securely.
