12-volt DC Powered Pumps (Model L 5016):
This GPI Oil Pump is factory wired for 12-volt DC. Circuit
must be protected with a 50 amp automotive-type fuse
(not supplied).
The power cord is not supplied with the pump. GPI rec-
ommends a minimum power cord of 10/3 AWG. Do not
exceed 15 feet of cord.
Do not operate pump dry. Damage to pump could
occur.
Before rst usage, pour oil into pump outlet port to coat
pumping element.
1. Place ball valve into the receiving tank to be lled.
2. Turn on the motor.
3. Open the ball valve and ll the container to the desired
level. If ow does not occur within 15 seconds, shut
off motor and refer to the priming information in the
Troubleshooting Section.
4. Shut off the nozzle.
5. Turn off the motor.
Motor Protector
The AC pumps contain thermal motor protection. If the
pump overheats the unit will shutoff.
If the motor shuts off, follow these instructions:
Model L 5132: Turn off the switch. Allow the motor to
cool before restarting.
Model L 5116: Turn off the switch. Allow the motor to
cool. Push the button to manually reset the protector.
Model L 5016: The 12-volt model should be protected by
an inline fuse (not supplied). If the motor shuts off,
check the fuse.
Disconnect power and relieve pressure in the system by
opening the nozzle before servicing the pump.
This pump is designed for minimum maintenance. Motor
bearings are sealed and require no lubrication. Inspect
the pump and components regularly for leaks and make
sure the hose, ball valve and components are in good
condition.
Use of the pump with unauthorized uids will void the
warranty.
Remove and clean the strainer if low ow is noticed.
To clean the strainer, remove the three screws on the
strainer cover. Remove cover and pull out screen. Clean
screen and reinstall. Care should be taken not to dam-
age the O-ring.
5. To prevent pressure buildup and possible leaks
through the ball valve, make sure the tank is vented.
Installing Discharge Plumbing on

1. Install a 90 degree elbow to the pump outlet using
oil resistant pipe sealant.
2. Install the hose and ball valve using oil resistant pipe
sealant on the threads. Tighten securely.
Electrical Installation
Electrical wiring must be done by a licensed electri-
cian. Shut off all power before connecting wires to
motor. Failure to follow these wiring instructions
may result in death or serious injury from shock,
re or explosion.
115-/230-volt AC Powered Pumps
(Models L 5116 & L 5132):
This GPI Oil Pump is factory wired for 115-volt AC. These
motors have the capability to run on 230-volts if properly
wired by an electrician. Power to the unit should be sup-
plied from a dedicated circuit breaker.
If AC extension cords are used, they must be capable of
safely carrying the rated motor current. Use only heavy
duty, 3-wire, grounded extension cords.
NOTE: Many building codes require Ground Fault Circuit
interrupt (GFCI) protection.
Motor Ratings (FLA):
115-/230-volt AC:
1/2 HP, 1725 RPM – 7.5/ 3.7 amps
1 HP, 3450 RPM – 13/ 6.4 amps
12-volt DC:
