ELECTRIC SHOCK HAZARD
Improper grounding or an improper setup and usage of an isolated waterborne system can cause a
hazardous condition and result in an electric shock or other serious injury.
D Ground the equipment, personnel in or close to the spray area, the object being sprayed, and all
other electrically conductive objects in the spray area. See Ground the System on page 17.
D The gun must be connected to a voltage isolation system that will discharge the system voltage
when the gun is not in use.
D All components of the isolation system that are charged to high voltage must be contained within a
fence or enclosure that prohibits personnel from making contact with the high voltage components
before the system voltage is discharged.
D The gun turbine air supply must be interlocked with the isolation system to shut off the turbine air
supply anytime the isolation system enclosure or safety fence is opened.
D The voltage isolation system must be interlocked with the spray area entrance to automatically
discharge the voltage and ground the fluid whenever someone enters the spray area.
D The areas of the waterborne fluid hose that are accessible to the personnel must be covered by
the conductive hose layer. The area on the hose that is not covered by the conductive hose layer
must be inside the voltage isolation system enclosure. Refer to Fig. 15, page 17.
D Only use the red-colored Graco electrically conductive gun air hose with this gun. Do not use the
black or grey-colored Graco air hoses.
D Install only one continuous Graco waterborne fluid hose between the isolated fluid supply and the
spray gun. Do not splice hoses together.
D Follow the Fluid Voltage Discharge and Grounding Procedure on page 19 when instructed to
discharge the voltage; before cleaning, flushing, or servicing the system; before approaching the
front of the gun or the gun-mounted fluid regulator; and before opening the safety fence or the
enclosure for the isolated fluid supply.
D Do not use the Graco ES Display Module readings to determine if your system is discharged. The
display modules will only display the system voltage while the gun power supply is operating.
Follow the Fluid Voltage Discharge and Grounding Procedure to ensure the system is dis-
charged.
D Do not enter a high voltage or hazardous area until all high voltage equipment has been
discharged.
D Do not come within 2 ft. (610 mm) of the gun nozzle or gun-mounted fluid regulator during gun
operation or until after following the Fluid Voltage Discharge and Grounding Procedure.
D If there is any static sparking while using the equipment, stop spraying immediately. Identify and
correct the problem.
D Follow the warnings and instructions in the voltage isolation system manual.
