Grounding
The following are minimum grounding requirements
for a basic electrostatic 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.
Pump: ground the pump by connecting a ground
wire and clamp as described in your separate pump
instruction manual.
Electrostatic Air-Assisted Spray Gun: ground the gun
by connecting the Graco Grounded Air Hose and
connecting the air hose ground wire to a true earth
ground. See Check Electrical Grounding, page
14.
Air compressors: ground the equipment according to
the manufacturer's recommendations.
All air and fluid 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.
All persons entering the spray area: shoes must have
conductive soles, such as leather, or personal
grounding straps must be worn. Do not wear shoes
with non-conductive soles such as rubber or plastic.
If gloves are worn, cut off fingers or cut out palm
area, to ensure your hand contacts the grounded
gun handle.
Object being sprayed: keep the workpiece hangers
clean and grounded at all times. Resistance must
not exceed 1 megohm.
The floor of the spray area: must be electrically con-
ductive and grounded. Do not cover the floor with
cardboard or any non-conductive material which
would interrupt grounding continuity.
Flammable liquids in the spray area: must be kept in
approved, grounded containers. Do not use plastic
containers. Do not store more than the quantity
needed for one shift.
All electrically conductive objects or devices in the spray
area: including fluid containers and wash cans, must
be properly grounded.
WARNING
Fire, Explosion, and Electric Shock
Hazard
When operating the electrostatic gun, any
ungrounded objects in the spray area (peo-
ple, containers, tools, etc.) can become elec-
trically charged. Improper grounding can
result in static sparking, which can cause a
fire, explosion, or electric shock. Follow the
grounding instructions below.
