GENERAL INFORMATION
Your pump is designed for use only with thin viscosity
petroleum fuels such as 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 uids other than those for which it was
designed. Using the pump with other fuels can damage
components and void the warranty. Use of alcohol blends
above 10% (E10) and biodiesel blends above 5% (B5)
have not been reviewed by UL.

PRO35 UL Listing.
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.
How to Use This Manual
The purpose of this manual is to assist you in installing,

INSTALLATION
Mechanical Connections
WARNING
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.
All threaded fuel connections must be sealed with thread
tape or a pipe thread sealing compound approved for
use with petroleum fuels.
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 suction
pipes shorter than 15 ft. (4.6 m). 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 1¼ in.
galvanized steel 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
(Not applicable to pumps with -RD sufx)
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 ¼"-20 x ½" bolts and the two at
washers from the switch coverplate.
2. Place the two bolts through the nozzle cover and then
place the two at washers on the bolts. The washers
are used as spacers to set the nozzle hanger away
from the switch coverplate.
3. Align the bolts with the two threaded holes on the
switch coverplate; thread the bolts into the holes.
Torque bolts to 45-60 in/lb (Figure 1).
FIGURE 1
A standard 15-amp breaker is recommended.
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, ensure that the wire is insulated and enclosed
within the electrical cavity of the pump.
CAUTION
Connect pump to the proper voltage source. PRO35 series pumps
are designed to operate on 115 VAC, 60 HZ or 230 VAC, 60 HZ.
Connection to improper voltage will damage pump. Pump is set
at factory for low voltage (115-volt). For high voltage applications
(230-volt) see wiring diagram located inside electrical coverplate.
Wiring Details
1. Remove electrical coverplate (Figure 2). Install conduit and cable from switchbox to pump electrical box.
Wiring must be in accordance with Class I, Division 1
requirements in the applicable national electrical code.
FIGURE 2
Switch Locking Lever
Attention: The PRO35-115RD remote dispenser pump
incorporates an external switch locking lever that locks the
pump switch in the “ON” position. The pump is typically
shut off using the remote dispensing device “ON-OFF”
mechanism.

DANGER
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, 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.
