ALWAYS use the lowest pressure possible when
flushing and use a grounded metal waste container.
Grounding
All components of the system, except the gun and paint
hoses, must be electrically grounded. Be sure the
power circuit is properly grounded.
When flushing, avoid conductive solvents, if possible.
Be sure to turn off H.V. Power Supply before flushing,
and to remove all solvent from gun before turning on
high voltage.
Be sure your gun is not grounded.

The object being coated must be grounded.
Keep work hangers and conveyor equipment clean so
work pieces are well grounded.
How The
Air Spray Gun Works
A transformer supplies high voltage current through the
cable to the gun’s ionizing electrode, where the
trostatic field is developed. The pump supplies paint

through the hose and gun, where it is electrostatically
charged as it passes the ionizing electrode. The charged
paint is attracted to the grounded work piece, wrapping
around it and coating surfaces indirectly.

and local codes for the installation of electrical
apparatus in a Class 1, Divisions 1 and 2 Hazardous
