GROUNDING
PAINT CIRCULATION SYSTEMS
Proper hose grounding continuity is essential
to maintaining a grounded spray system.
Check the electrical resistance of your air and
fluid hoses at least once a week. If our hose
does not have a tag on it which specifies the
maximum electrical resistance, contact the
hose
supplier

meter in the appropriate range for your hose
to check the resistance.
exceeds the recommended limits, replace it
immediately.
An ungrounded or poorly
grounded hose can make your system
hazardous. Also, read FIRE OR EXPLOSION
HAZARD.
FIRE OR EXPLOSION HAZARD FOR PAINT
CIRCULATION SYSTEMS
Static electricity is created by the high velocity
flow of fluid through the pump and hose. If
every part of the spray equipment is not
properly grounded, sparking may occur, and
the system may become hazardous. Sparking
may
also
occur
unplugging a power supply cord. Sparks can
ignite fumes from solvents and the fluid being
sprayed, dust particles and other flammable
substances, whether you are spraying indoors
or outdoors, and can cause a fire or explosion
and
serious
bodily
damage. Do not plug in or unplug any power
supply cords in the spray area when there is
any chance of igniting fumes still in the air.
If you experience any static sparking or even a
slight shock while using this equipment, STOP
SPRAYING IMMEDIATELY. Check the entire

To reduce the risk of static sparking, ground
the pump, object being sprayed, and all other
spray equipment used or located in the spray
area. CHECK your local electrical code for
detailed grounding instructions for your area
and type of equipment. BE SURE to ground

on a grounded surface. Do not place the
pail on a nonconductive surface, such as
paper or cardboard, which interrupts the
grounding continuity.
9. To maintain grounding continuity when
flushing or relieving pressure, always hold
a metal part of the spray gun firmly to the
side of a grounded metal pail, then trigger
the spray gun.
