Operation
Fluid Voltage Discharge and Grounding Procedure
WARNING
ELECTRIC SHOCK HAZARD
The high voltage fluid supply is charged with high voltage until the voltage is dis- charged. Contact with the charged com-
ponents of the isolation system or spray gun elec- trode will cause an electric shock. To avoid an elec- tric shock, follow the Fluid Voltage Discharge and Grounding Procedure:
Dwhen instructed to discharge the voltage,
Dbefore cleaning, flushing, or servicing the sys- tem equipment,
Dbefore approaching the front of the gun,
Dand before opening the safety fence or the enclosure for the isolated fluid supply.
NOTE: An accessory grounding rod, part no. 210084, is available to discharge any voltage remaining on a system component. Contact your Graco representative to order it.
1.Turn off the gun electrostatics by turning the gun ES
2.Discharge the voltage at the voltage isolation system by following the procedure specified in the voltage isolation system instruction manual.
3.Touch the electrode of the gun with a grounded rod to make sure that the voltage has been dis- charged. If an arc is seen, verify that the electros- tatics are turned off or see Troubleshooting , page 24, or the voltage isolation system manual for other possible problems. Resolve the problem before proceeding.
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to prevent the system from starting or spraying acci- dentally. To reduce the risk of an injury from acci- dental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Proce- dure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the fluid nozzle.
1.Follow the Fluid Voltage Discharge and Grounding Procedure, at left.
2.Relieve fluid pressure in the fluid supply and voltage isolation system as instructed in their instruction manuals.
3.Turn off the fluid supply to the gun.
4.Shut off the air supply to the spray gun. The
5.Trigger the gun into a grounded metal waste container to relieve fluid pressure.
