WARNING
FIRE AND EXPLOSION HAZARD
When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be
aware that flammable fumes can ignite or explode. To help prevent fire and explosion:
• Use equipment only in well-ventilated area.
• Eliminate all ignition sources, such as cigarettes and portable electric lamps.
• Ground all equipment in the work area.
• Keep work area free of debris, including rags and spilled or open containers of solvent and gasoline.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Use only grounded hoses.
•Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment
until you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause
electric shock.
• Turn off and disconnect power cord before servicing equipment.
• Connect only to grounded electrical outlets.
• Use only 3-wire extension cords.

Installation
Grounding
Pump
NOTE: The reference numbers in the following section
refer to Notes:, page 17.
NOTE: Pipe/thread sealant is user supplied, do not use
the PVC cement supplied with the product.
The oil transfer pumps are positive displacement
pumps. The motors are drip proof rated and have
sealed bearings and require minimal maintenance. All
models come with hose, nozzle, 34 in. (864 mm)
suction tube assembly, and bung adapter.
Mount Pump on Drum
1. Install the bung adapter (14) in the drum bung and
tighten.
2. Assemble the suction tube sections (18) by
applying PVC cement (21) to the inside diameter of
the PVC couplers (19, 20). Make sure that the PVC
cement (21) is applied to the complete inside
diameter and slide the pipe sections into the
coupler with a twisting motion.
3. Apply pipe sealant to the threaded end of the
suction tube, then screw the tube into the pump
inlet port, making sure that the tube is tight.
4. Insert the suction tube attached to the pump
through the bung adapter, and lower the pump
onto the bung adapter. Position the pump, as
desired, then tighten the swivel nut (23) to the bung
adapter (14).
Mount Hose and Nozzle
1. Before connecting the hose to the pump, pour 8 oz.
(0.24 l) of oil into the pump outlet port so that the
pump does not run dry during the initial startup.
2. Apply pipe sealant to the male threads of the elbow
(12), then secure the elbow into the outlet port.
3. Apply pipe sealant to one end of the hose assembly
(17), then twist the hose end into the elbow.
4. Apply pipe sealant to the other end of the hose
assembly (17).
5. Apply thread sealant onto the nozzle (15) end that
connects to the ball valve (16).
6. Fasten the ball valve and nozzle (15, 16) onto the
hose assembly, positioning the nozzle (15) down for
dispensing.
Electrical Installation
230 VAC
The 230 VAC model is shipped with a power cord with
no electrical plug. An appropriate electrical plug that
meets local electrical codes must be installed.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.

Operation
3A8558C 7
Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn off and disconnect the power supply.
2. Trigger the dispense valve into a grounded waste
container to relieve pressure.
Duty Cycle
The pump is designed to operate for a 50% duty cycle.
It can operate up to a maximum of 30 minutes of run
time, with an equal amount of down time.
Thermal Overload
The motor has a thermal overload switch that shuts the
motor down when overheated. If the unit overheats,
allow approximately 45 minutes for the unit to cool.
Once the unit has cooled down, the switch will close
and the unit will restart.
Pump Start Up
1. Check that the ball valve is in the OFF position.
2. Turn the power switch, located on the back of the
motor, to the ON position to start the pump.
NOTE: The pump has an internal bypass valve
(Pressure Relief Valve) that opens when the pump
discharge pressure exceeds 65 psi. If the flow is
blocked, the fluid will bypass within the pump.
3. Insert the nozzle (15) into the container and open
the ball valve (16) to dispense fluid.
4. Turn the switch to the OFF position immediately
after finishing dispensing.
5. Close the ball valve (16).
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid and moving
parts, follow the Pressure Relief Procedure when you
stop dispensing and before cleaning, checking, or
servicing the equipment.
NOTICE
Never allow the pump to operate dry. Make sure that
the pump has fluid in it when the pump is initially
installed. Do not run the pump for more than five (5)
minutes with the pump discharge blocked. Do not
operate the pump continuously more than 30 minutes
in one (1) hour. Failure to follow these instructions can
result in damage to the pump.
To reduce risk of injury from motor starting
unexpectedly when it cools, always turn the power
switch to OFF if the motor shuts down.

Recycling and Disposal
8 3A8558C
