WARNING
Electric Shock Hazard
Improper grounding, setup, or usage of an isolated waterborne system can cause a hazardous
condition and result in electric shock or other serious injury.
• Ground the equipment, all personnel in or close to the spray area, the object being sprayed,
and all conductive objects in the spray area. See Grounding, page 17.
• The gun must be connected to a voltage isolation system that will discharge the system volt-
age when the gun is not in use.
• All components of the isolation system that are charged to high voltage must be contained
within an enclosure that prohibits personnel from making contact with the high voltage compo-
nents before the system voltage is discharged.
• Follow the Fluid Voltage Discharge and Grounding Procedure on page 20 when instructed
to discharge the voltage; before cleaning, flushing, or servicing the system; before approach-
ing the front of the gun; and before opening the safety enclosure for the isolated fluid supply.
• Do not touch the gun nozzle or come within 4 in. (102 mm) of the nozzle during gun operation
or for 30 seconds after operation stops, to allow the voltage to discharge through the bleed
resistor. Place the gun in the holster (accessory) during this 30 second period. Refer to Fluid
Voltage Discharge and Grounding Procedure, page 20.
• Electrically connect a metal part of the fluid supply unit to the bleed resistor.
• The gun air supply must be interlocked with the isolation system to shut off the air supply any-
time the isolation system enclosure is opened.
• Use only the red-colored Graco electrically conductive gun air hose with this gun. Do not use
black or grey-colored Graco air hoses.
• Install only one continuous Graco waterborne fluid hose between the isolated fluid supply and
the spray gun. Do not splice hoses together.
• Do not enter a high voltage or hazardous area until all high voltage equipment has been dis-
charged.
