Setup
Pressure Relief
Follow the Pressure Relief Procedure whenever
you see this symbol.
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 in system using two wrenches
working 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 fitting.
NOTE: When loosening pump element fitting, do NOT
loosen pump element. Loosening pump element will
change the output volume.

Connecting to Auxiliary Fittings
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.
•
Always use two wrenches working in opposite
directions when connecting anything to pump
element or auxiliary fittings. See F
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 45.
•
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 47.
