imminently hazardous
situation which, if not

death or serious injury.

potentially hazardous
situation which, if not
avoided, could result in
death or serious injury.

There are inherent dangers wherever flammable 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 filters must be listed for use with fuel transfer systems.
The flow of fuel through a hose and nozzle can generate static
electrical charges and dangerous sparking can result in fire 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 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.

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.
Your pump must be mounted on a vented tank. If the tank is not
vented, contact your GPI 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 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-inch
female tank fitting. For the suction pipe, a 1-1/4-inch 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 pump inlet port.
Install Nozzle Hanger (Not applicable to pumps with
-RDP suffix)
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 and the two (2)
flat washers from the switch coverplate.
