Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating, ground the system as
explained below. Also read the section
FIRE AND EXPLOSION HAZARD on
page 4.
Static electricity is created by the flow of fluid through
the pump and hose. If the pump is not properly
grounded, sparking may occur, and the system may
become hazardous. Sparking may also occur when
plugging in or unplugging a power supply cord. Sparks
can ignite fumes from solvents, dust particles and
other flammable substances, whether you are
operating indoors or outdoors, and can cause a fire or
explosion and serious bodily injury and property
damage.
To reduce the risk of static sparking, ground all the
dispensing equipment used or located in the work
area. Check you local electrical code for detailed
grounding instructions for your are and type of
equipment. Be sure to ground all of this equipment.
D Pump or sprayer: If using an electric sprayer, plug
the power supply cord or extension cord, each
equipped with an undamaged three-prong plug, into
a properly grounded outlet. Do not use an adapter.
All extension cords must have three wires and be
rated for 15 amps. If using another type of sprayer
or pump, ground it by connecting a grounding wire
(12 ga minimum) from the pump or sprayer's
grounding lug to a true earth ground.
D Air compressor or hydraulic power supply: Follow
the local code.
Installation
D Fluid hoses: Use only electrically conductive hoses
with a maximum of 500 feet (150 m) combined
hose length to ensure grounding continuity.
D Spray gun: Obtain grounding through connection to
a properly grounded fluid hose and sprayer or
pump.
D Supply container: Follow the local code.
D Object being sprayed: Follow the local code.
D All solvent pails used when flushing: Follow the
local 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
continuity.
D To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
gun firmly to the side of a grounded metal pail, then
trigger the gun.
To ground the pump, loosen the grounding lug
locknut (W) and washer (X). Insert one end of a
12 ga (1.5 mm
slot (Z) in the lug, and tighten the locknut securely.
Connect the other end of the wire to a true earth
ground. To order a ground wire and clamp, order
Part No. 222011.
