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:

Electrically connect the

voltage isolation system to a true earth ground.

See Ground the Cabinet, page 16.

•

Electrostatic Air-Assisted Spray Gun:

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

Check Gun Electrical Grounding, page 23.

•

Object being s

prayed:

keep the workpiece hangers

clean and gro

unded at all times.

•

All electr

ically conductive objects or devices in the

spray area

must be properly grounded.

•

Fluid and waste containers:

ground all ﬂuid and

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.
