Warnings
WARNING
ELECTRIC SHOCK HAZARD
Improper grounding, setup, or usage of an isolated waterborne system can result in electric shock. To
help prevent electric shock:
• Ground all equipment, personnel, object being sprayed, and conductive objects in or close to spray
area. See Grounding instructions.
• Connect the electrostatic gun to a voltage isolation system that will discharge the system voltage
when not in use.
• All components of the isolation system that are charged to high voltage must be contained within an
isolation enclosure that prevents personnel from making contact with the high voltage components
before the system voltage is discharged.
• Follow the Fluid Voltage Discharge and Grounding Procedure when instructed to discharge the
voltage; before cleaning, flushing, or servicing the system; before approaching the front of the gun;
and before opening the isolation enclosure for the isolated fluid supply.
• Do not enter a high voltage or hazardous area until all high voltage equipment has been discharged.
• Do not touch the gun nozzle or electrode, or come within 4 in. (102 mm) of the electrode during gun
operation. Follow the Fluid Voltage Discharge and Grounding Procedure.
• Interlock the gun air supply with the voltage isolation system to shut off the air supply anytime the
isolation system enclosure is opened.
• Only use the red-colored Graco electrically conductive gun air hose with this gun. Do not use
black or gray-colored Graco air hoses.
• Do not splice hoses together. Install only one continuous Graco waterborne fluid hose between the
isolated fluid supply and the spray gun.
