configurations only.
•
Always mount the G3 oil models upright.
•
Mount top fill G3 pump models so that there is a
a minimum clearance of four inches (4.0 in.)
(10.2 cm) above the reservoir to allow for lid
removal and filling.
•
If the G3 grease model is going to be operated
in a tilted or inverted position for any period of
time, you must use a model that includes a follower plate, otherwise the G3 must be mounted
upright. Refer to your model number to confirm
if a follower plate was installed on your pump.
See page 4, Understanding the Model Number to identify this character in your model number.
If the product is permanently connected, it must be:
•
it must be rated for the product electrical specifications.
•
Use the three fasteners (included) to secure the
G3 to the mounting surface.
•
it must be an approved, 3-wire grounding type
attachment plug.
•
Some installations may require an additional
reservoir support bracket. See table below for
bracket information.
•
it must be plugged into an outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
•
when repair or replacement of the power cord or
plug is required, do not connect the grounding wire
to either flat blade terminal.
Improper installation of the grounding conductor may
result in a risk of electric shock. This product must be
installed by a qualified electrician in compliance with
all state and local codes and regulations.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
NOTICE
Do not attach unsupported equipment to auxiliary fittings such as fill ports and pump element. Attaching
unsupported equipment to these fitting can result in
irreparable housing damage.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
Relieve pressure at the pump element using two
wrenches working in opposite directions on the pump
element and pump element fitting to slowly loosen fitting
only until fitting is loose and no more lubricant or air is
leaking from fitting. Repeat for each pump element
installed (FIG. 17).
NOTE: When loosening pump element fitting, do not
loosen pump element. Loosening pump element will
change the output volume.
•
Always use two wrenches working in opposite
directions when connecting anything to pump element or auxiliary fittings. See FIG. 17 for an example.
•
Torque pump element fittings to 50 in. lbs (5.6
N•m).
•
When connecting pump element into housing
torque to 50 in. lbs (5.6 N•m).
Pressure Relief Valves
To prevent over-pressurization, which can result in
equipment rupture and serious injury, a pressure
relief valve appropriate for the lubrication system
must be installed close to every pump outlet to alleviate unintended pressure rises in the system and protect the G3 pump from damage.
•
Only use a pressure relief valve that is rated for
no more than the working pressure of any component installed in the system. See Technical
Data, page 32.
•
Install a pressure relief valve close to every pump
outlet; before any auxiliary fitting.
NOTE: A pressure relief valve can be purchased from
Graco. See Parts, page 34.

4. Tighten the pump element fitting. Torque fitting to 50
in. lbs. (5.6 N•m).
•
The amount of dispensed volume varies depending
upon external conditions, such as lubricant
temperature and back pressure from downstream
connections.
•
Use of these volume adjustments in conjunction
with setting the ON time of the pump allows for
control of the output volume.
•
Use these volume adjustments as a starting point
and adjust as needed to ensure the desired
lubrication dispense.
It may be necessary to repeat this outlet volume
setup procedure after the pump is operating to
re-adjust the volume of dispensed fluids.
1. Follow the Pressure Relief Procedure, page 18,
before making any adjustments to the pump volume.
2. Use a wrench to turn the pump element counterclockwise to loosen. Do not remove the entire pump
element. Only back the pump element out enough
to allow a spacer to be slid on or off. (FIG. 18).

•
Do not overfill the reservoir.
3. If needed, remove or insert spacers to achieve the
required pump output volume. A tool may be
needed to facilitate removal.
•
Do not operate the G3 pump without a reservoir
attached.
The pump volume control is set using no spacers,
one (1) or two (2) spacers (FIG. 18).
NOTICE
•
Always clean the fitting (D) (FIG. 19) with a clean
dry cloth prior to filling the reservoir. Dirt and/or
debris can damage the pump and/or the lubrication system.
•
When changing greases, always use compatible
fluids or greases.

Setup
Auto-Fill Shut Off
The Auto-Fill Shut Off is used for refilling the G3
reservoir in an automatic lubrication system. As fluid is
added to the reservoir, the plate valve is pushed up to
the top of the reservoir, pushing the valve pin and
closing the inlet fluid path.
COMPONENT RUPTURE HAZARD
The maximum working pressure of each component
in the system may not be the same. To reduce the
risk of over-pressurizing any component in the system, be sure you know the maximum working pressure of each component. Never exceed the maximum
working pressure of the lowest rated component in
the system. Over-pressurizing any component can
result in rupture, fire, explosion, property damage and
serious injury.
When the fluid refilling path closes, the refilling line
pressurizes and brings the refilling pump to a
pressurized stall condition.
NOTE: The operator must monitor the system while
filling the reservoir to prevent overfilling.
Load Grease
Regulate input pressure to the remote fill pump so
that no fluid line, component or accessory is over
pressurized.
To ensure optimal performance from the G3 pump:
•
Only use NLGI #000 - #2 greases appropriate for
the application, automatic dispensing, and the
temperature. Consult with the machine and lube
manufacturer for details.
Remote Fill with Remote Fill Manifold
•
Do not overfill the reservoir.

•
Do not operate the G3 pump without a reservoir
attached.
The fill valve is used to relieve pressure in the refill line
and to reset the Auto Fill Shut Off. See Fill Valve instruction manual 333393. Graco fill valve, part no. 77X542 is
available. Contact your local Graco distributor.
NOTICE
Use care when filling the reservoir with a pneumatic or
an electric transfer pump, to not pressurize and break
the reservoir.
Change Grease
The reference letters used in the following instructions
refer to FIG. 5, pages 10.
1. Pull out and hold the Pressure Relief Knob (T) long
enough to relieve line pressure between Fill Manifold (N) and Auto-Fill Shut Off Valve (B).
2. Verify that the Auto-Fill Shut Off (B) pin is down,
indicating it is reset (FIG. 22).
When changing greases, always use compatible fluids
or greases.
The remote filling station pump stalls (dead-heads)
when the reservoir is full, causing the supply system
pressure to rise to the maximum output pressure
of the filling station pump. To help prevent equipment
damage or serious injury caused by pressurized fluid,
such as skin injection or injury from splashing fluid,
always use a remote filling station pump with a maximum output pressure of 5100 psi (35.1 MPa, 
351.6 bar) and use supply hoses with a minimum
pressure rating of 5100 psi (35.1 MPa, 351.6 bar).

twice as long as Pump ON (Run) time. If alternative
ON / OFF times are required, contact Graco Customer Service for assistance.
Low Level Output Option
Some G3 pumps without controllers include a Low Level
Output Option. It can be configured with an M12 connector in code location “G” or with a DIN connector in
code location “K”. (See Understanding the Model
Number, page 4.) The low level signal is monitored
across PINS 3 and 4. For PIN 3 and 4 locations and wiring information the Low Level Outputs diagram, page
15.
NOTE: A low level warning is triggered when the controller detects PINS 3 and 4 have momentarily closed.
Grease Pumps
When the grease level has reached a low warning level,
PINS 3 and 4 momentarily close (1 time per paddle revolution) sending the signal that the fluid has reached a
low level to the controller.
To ensure that a low level condition has been met, 3 or
more low level triggers must be detected within 1 minute
or less.

Important Information regarding Pressure Relief
Valve 16C807.
 Pressure Relief Valve 16C807 can only be used
on the G3 Pump. It is not intended for use with any
other products.
The pressure relief valve uses a
pressure adjustment screw (a) to
set the pressure release point. It
is not intended as a way to
relieve pressure during normal
operation, but as a protective
measure in the event there is an
unintended pressure increase in
the system. Do not use this pressure relief valve a means of
relieving pressure in day-to-day,
normal cycle operation.

No. 16D984
a
The pressure adjustment screw
will require periodic adjustments.
Whenever the valve is set/adjusted (after the set point is
found) it is important to ensure that the valve is not bottomed out and there is at least 1/2 turn of adjustment
remaining. This is determined by turning the screw (a)
1/2 turn and then back turning it out again.
