System Wiring
Fuses
Fuse Kits are available from Graco. The following Table
identifies the correct fuse to use for your input voltage
and the corresponding Graco Kit number.
Recommendations for Using Pump in
Harsh Environments
• If using a DIN style power or alarm harness with a
right angle mating connector, make sure the con-
nector does not exit the unit in the UP direction.
• Use a corrosion preventative electrical grease on all
contacts.
NOTICE
Observe precautions for handling electrostatic sensi-
tive devices. Touch ground before handling pump.
AUTOMATIC SYSTEM ACTIVATION HAZARD
If the system is equipped with has an automatic timer
(user supplied) that activates the pump lubrication
system when power is connected or when exiting the
programming function, unexpected activation of the
system could result in serious injury, including skin
injection and amputation.
Before you install or remove the lubrication pump
from the system, disconnect and isolate all power
supplies and relieve all pressure.
FIG. 5
NOTICE
Fuses (user supplied) are required on all DC mod-
els. To avoid equipment damage:
• Never operate G3 Pump DC models without a

Pressure Relief
Follow the Pressure Relief Procedure whenever
you see this symbol.
Relieve pressure in system using two wrenches work-
ing in opposite directions on pump element and pump
element fitting to slowly loosen fitting only until fitting
is loose and no more lubricant or air is leaking from fit-
ting.
NOTE: When loosening pump element fitting, do NOT
loosen pump element. Loosening pump element will
change the output volume.
Connecting to Auxiliary Fittings
Pressure Relief Valves
NOTE: A pressure relief valve can be purchased from
Graco.
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.
FIG. 8
NOTICE
Do not attach unsupported equipment to auxiliary fit-
tings such as fill ports and pump element. Attaching
unsupported equipment to these fitting can result in
irreparable housing damage.
• Always use two wrenches working in opposite
directions when connecting anything to pump ele-
ment or auxiliary fittings. See FIG. 8 for an exam-
ple.
• 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).
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 allevi-
ate unintended pressure rises in the system and pro-
tect the G3 pump from damage.
• Only use a pressure relief valve that is rated for
no more than the working pressure of any com-
ponent installed in the system.
• Install a pressure relief valve close to every pump
outlet; before any auxiliary fitting.

Setup
12 3A6319A
Setting Pump Outlet Volume
NOTE:
• Before making any adjustments to pump volume,
Relieve Pressure following procedure on page 11.
• Only use Graco supplied spacers to control output
volume.
• 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. Use a wrench to turn pump element counter-clock-
wise to loosen. Do not remove entire pump element.
Only back pump element out enough to allow
spacer to be slid on or off (FIG. 9).
2. If needed, remove or insert spacers to achieve
required pump output volume. A tool may be
needed to facilitate removal.
Pump volume control is set using either no (0) spac-
ers, 1 or 2 spacers (FIG. 9).
Do not use more than 2 spacers to adjust output vol-
ume.
3. Tighten pump element fitting. Torque fitting to 50 in.
lbs (5.6 N•m).
• The amount of dispensed volume can vary depend-
ing on external conditions such as lubricant tem-
perature and back pressure from downstream
connections.
• Use of these volume adjustment in conjunction with
setting the ON time of the pump will allow for control
of the output volume.
• Use these volume adjustments as a starting point
and adjust as necessary to ensure desired lubrica-
tion dispense.
Loading Grease
To ensure optimal performance from the G3:
• Only use NLGI #000 - #2 greases appropriate for
your application, automatic dispensing, and the tem-
perature. Consult with machine and lube manufac-
turer for details.
• The reservoir can be filled using a hand operated
pump, pneumatic pump or electric transfer pump.
• Do not overfill.
• Do not operate G3 without reservoir attached.
1. Connect fill hose to inlet fitting.
2. For higher viscosity fluids, start pump to rotate stir-
ring paddle during fill to prevent air pockets from
forming in grease. Do not exceed 30 minutes run
time.
For models using an external controller, start pump
operation per your controller specifications.

3. Fill reservoir with grease until seal of follower plate
breaches the vent hole (FIG. 10) and the majority of
air is expelled from the reservoir.
NOTE: Vent port, located in rear of reservoir, should not
be used as an overfill port/indicator.
4. Remove fill hose.
Priming
NOTE: It is not necessary to prime pump every time
pump is filled with lubricant.
Pump only requires priming the first time it is used or if it
is allowed to run dry.
1. Loosen pump element fitting (FIG. 11).
NOTE: When loosening pump element fitting, do NOT
loosen pump element. Loosening pump element will
change the output volume
2. Only run pump until air-free lubricant is dispensed
out of element fitting (FIG. 12).

Pump Operation
14 3A6319A
Pump Operation
The G3 Pump can be controlled using an external, user
supplied, power source and controller.
Refer to the Typical Installation diagrams starting on
page 7 for correct location of the required fuses.
NOTE:
• When using an external power source and control-
ler, Pump ON (Run) Time should be set for no lon-
ger than 30 minutes.
• In most cases, Pump OFF (Rest) Time should be
twice as long as Pump ON (Run) time. If alternative
ON / OFF times are required, contact Graco Cus-
tomer Service for assistance.
Low Level Output Option
Some G3 pumps without controllers include a Low Level
Output Option. 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 10.
NOTE: A low level warning is triggered when the con-
troller detects PINS 3 and 4 have momentarily closed.
When the grease level has reached a low warning level,
PINS 3 and 4 momentarily close (1 time per paddle rev-
olution) 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.
See FIG. 13 for an illustration of a typical Low Level Out-
put response to low grease level.

Pressure Relief Valves
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 pres-
sure relief valve a means of
relieving pressure in day-to-day,
normal cycle operation.
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 bot-
tomed 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.
NOTE: Turning adjustment screw (a) clockwise
increases pressure.
