WARNING
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury.
D Ground the equipment and the object being sprayed. Refer to Grounding on page 5.
D If there is any static sparking or you feel an electric shock while using this equipment, stop spray-
ing immediately. Do not use the equipment until you identify and correct the problem.
D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being sprayed.
D Keep the spray area free of debris, including solvent, rags, and gasoline.
D Electrically disconnect all equipment in the spray area.
D Extinguish all open flames or pilot lights in the spray area.
D Do not smoke in the spray area.
D Do not turn on or off any light switches in the spray area while operating or if fumes are present.
D Do not operate a gasoline engine in the spray area.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,
inhaled, or swallowed.
D Know the specific hazards of the fluid you are using.

Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, the mounting
cover and all electrically conductive objects or devices
in the spray area must be properly grounded. Check
your local electrical code for detailed grounding
instructions for your area and type of equipment.
Agitator and drum cover: Connect one end of the
ground wire (Y) to the ground connector (X) on the rim
of the drum cover. See Fig. 1. Connect the other end
of the ground wire to a true earth ground. See the
pump instruction manual (307986 for 230992, 307985
for model 230993, or 308793 for model 220575) for
instructions on grounding the pump.
Object being sprayed: Follow your local code.
Fluid supply container: Follow your local code.
Solvent pails used when flushing: Follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the pail
on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.
To maintain proper grounding continuity when flushing
or relieving pressure, always hold the metal part of the
spray gun firmly to the side of a grounded metal pail,
then trigger the gun.
Positioning the Unit
Select a convenient location for the unit. The air
valves for the pump (37) and agitator (5) must be fully
accessible.
System Accessories
WARNING
A bleed-type master air valve (N) and a fluid drain
valve (K) are required in your system. These
accessories help reduce the risk of serious injury,
including splashing of fluid in the eyes or on the
skin, and injury from moving parts if you are adjusting or repairing the pump or agitator.
The bleed-type master air valve relieves air
trapped between this valve and the pump after the
air is shut off. Trapped air can cause the pump to
cycle unexpectedly. Locate the valve close to the
pump. A red–handled bleed–type ball valve is
supplied to relieve air trapped in the air motor.
The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient. Order Part No. 210071.

Y
Fig. 1
Air and fluid hoses: Use only electrically conductive
hoses with 500 ft. (150 m) maximum combined hose
length to ensure grounding continuity.
Air compressor: Follow manufacturer’s recommendations.
Spray gun or dispensing valve: Ground through connection to a properly grounded fluid hose and pump.
