Graco 332305B Setup, Connecting to Auxiliary Fittings, Pressure Relief Valves

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 spraying 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.

Setup

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 FIG. 14 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 unin- tended 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 66.

•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 71.
