Gun Setup

Grounding

When operating the electrostatic gun, any
ungrounded objects in the spray area (people,
containers, tools, etc.) can become electrically
charged. Improper grounding can result in static
sparking, which can cause a fire, explosion, or
electric shock. Ground all equipment, personnel,
object being sprayed, and conductive objects
in or close to the spray area. Resistance must
not exceed 100 ohms. Follow the grounding
instructions below.
The following are minimum grounding requirements
for a basic electrostatic waterborne system. Your
system may include other equipment or objects which
must be grounded. Check your local electrical code
for detailed grounding instructions. Your system must
be connected to a true earth ground.
Voltage Isolation System:
•
voltage isolation system to a true earth ground.

the gun by connecting the red-colored Graco
Grounded Air Hose to the gun, and connecting the
air hose ground wire to a true earth ground. See

Object being sprayed:
•
clean and grounded at all times.
All electrically conductive objects or devices in the

spray area:
must be properly grounded.
Fluid and waste containers:
•
waste containers in the spray area. Do not use pail
liners unless they are conductive and grounded.
When flushing the spray gun, the container used
to catch the excess fluid must be electrically
conductive and grounded.
Air compressors:
• ground the equipment according
to the manufacturer's recommendations.
All air lines
• must be properly grounded. Use only
grounded hoses with a maximum of 100 feet (30.5
m) combined hose length to ensure grounding
continuity.
