Setup

Pressure Relief Procedure

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.

Disconnect and isolate all power supplies.

Relieve pressure in the system using two wrenches
working in opposite directions on the pump element and
pump element fitting to slowly loosen fitting only until the
fitting is loose and no lubricant or air is leaking from
fitting.
NOTE: When loosening the pump element fitting, do not
loosen the pump element. Loosening the pump element
changes the output volume.

Connect to Auxiliary Fittings

NOTICE
Do not attach unsupported equipment to auxiliary fit-
tings such as fill ports and pump element. Attaching
unsupported equipment to these fittings can result in
irreparable housing damage.
• Always use two wrenches working in opposite direc-
tions when connecting anything to pump element or
auxiliary fittings. See F
• Torque pump element fittings to 50 in-lb (5.6 N•m).
• Torque pump element to 65 in-lb (7.3 N•m) when
connecting to the housing.

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 each pump outlet to allevi-
ate unintended pressure rises in the system and pro-
tect the 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 before any auxiliary
fitting.
NOTE: A pressure relief valve may be purchased from
Graco. See Pressure Relief Valves, page 15.
