Connecting to Auxiliary Fittings

NOTICE
Do not attach unsupported equipment to auxiliary
fittings such as fill ports and pump element. Attach-
ing 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
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 the G3 pump it is
installed on. See Technical Data, page 57.
• 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 54.
