Resumen del manual
Be sure the electric power circuit is properly grounded. Be sure your gun is not grounded. Use un$rbunded paint hoses to gun only, and be sure your supply pump and the object you are painting are-grounded. All conductive objects within 10 ft (3 m) of the gun must be electrically grounded. Be sure your installation complies with all applicable local codes. ALWAYS use the lowest pressure possible when flushing and use a grounded metal waste container. 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. Operating Never use or store solvents in the spray area. NEVER IMMERSE THE SPRAY GUN IN SOLVENT OR OTHER LIQUID. The object being coated must be grounded. Keep work hangers and conveyor equipment clean so work pieces are well grounded. How The Elecnostatic Automatic Air Spray Gun Works A transformer supplies high voltage current through the cable to the gun’s ionizing electrode, where the electrostatic 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. Be sure your installation complies with Federal, State and local codes for the installation of electrical apparatus in a Class 1, Divisions 1 and 2 Hazardous Location. The particular type and size system for your operation will have to be custom designed for your needs. For a correctly sized system, contact the Grace Finishing System Division, Franklin Park, Illinois. Mount the gun on an insulated stationary support or reciprocator arm. The spray gun has a mounting hole to fit a 0.5 in. (13 mm) diameter rod. Use a mounting fixture which allows adjustment of the spray pattern direction and distance from the work. Install a normally closed, 3-way air solenoid valve in the cylinder air supply line. BEFORE CONNECTING AIR LINES BLOW THEM OUT TO REMOVE METAL CHIPS AND OTHER FOREIGN PARTICLES. Connect an air hose from the solenoid valve to the gun’s l/4” npt(m) cylinder air inlet. Connect an air supply line to the l/4” npt(m) atomizing air inlet. BEFORE CONNECTING FLUID LINES, BLOW THEM OUT WITH AIR AND FLUSH WITH SOLVENT. BE SURE THAT THE SOLVENT YOU USE IS COMPATIBLE WITH THE MATERIAL TO BE SPRAYED. Connect a fluid hose to the paint supply pump’s outlet and to the gun’s 3/8 npsm fluid inlet. Install fluid tip in gun. Be sure fluid pressure is relievedand high voltage turned off before installing tip.

The gun requires a minimum of 30 psi (2 bar) air pressure to the cylinder. Fluid Control Adjust the fluid flow to the proper rate, using a fluid regulator installed in paint line. It is best to adjust flow rate with a fluid regulator. Spray Pattern Control Turn air adjusting screw (36) counterclockwise for a wide flat spray pattern or clockwise to decrease to a round pattern. 2 307434 NOTE: When increasing to a wide, flat pattern, Connect high voltage cable to the high voltage adapter increase supply of fluid to gun to maintain (44. same coverage over larger area.

Flush out the gun with an approved solvent at the end of the work day. Wipe the outside of the gun with an Improper Spray Patterns approved gun cleaner. Remove the air cap and clean it. If ionizing wire of needle (41) is bent after cleaning, straighten wire so that it is centered in fluid stream. For an approved solvent or gun cleaner, see your local supplier or Grace Branch.
