Electrical Grounding - Graco A Series Instructions Manual

Electrical Grounding

WARNING
FIRE AND EXPLOSION HAZARD
Improper grounding could cause static
sparking, which could cause a fire or
explosion. To reduce the risk of property
damage or serious injury, follow the
grounding instructions below.
D Read and follow the warnings in Fire and
Explosion Hazard on page 3.
D Provide electrical grounding continuity throughout
the entire spray system as instructed below.
D Have a trained and qualified person perform all
electrical wiring.
D Comply with all applicable local, state, and
national fire, electrical, and other regulations.
The following grounding instructions are minimum require-
ments for a system. Your system may include other equip-
ment or objects that must be grounded. Check your local
electrical code for detailed grounding instructions for your
area and type of equipment. Your system must be connected
to a true earth ground.
Installation
D Ground the pump or sprayer as instructed in its
separate manual.
D Ground the air compressor or hydraulic power
supply according to the local electrical code and
the manufacturer's recommendations.
D Use electrically conductive fluid hoses with a
maximum combined hose length of 500 feet (150
m) to ensure grounding continuity.
D Ground the pole gun by connecting it to a properly
grounded fluid hose and pump or sprayer.
D Ground the fluid supply container, object being
sprayed, all solvent pails used when flushing
according to the local electrical code. Use only
metal pails, which are conductive. Do not place the
pail on a non-conductive surface, such as paper or
cardboard, which interrupts the grounding continu-
ity.
D To maintain grounding continuity when flush-
ing or relieving pressure, always hold a metal
part of the pole gun firmly to the side of a grounded
metal pail, then trigger the in-line valve.
