16 308584 Operation Fluid V oltage Discharge and Grounding Procedure W ARNING ELECTRIC SHOCK HAZARD The high voltage fluid supply is charged with high voltage until the voltage is dis- charged. Contact with the charged com- ponents of the isolation system or spray gun elec- trode will cause an electric shock.
308584 17 Operation Operating Checklist Check the following list daily , before starting to operate the system, to help ensure safe, efficient operation. ____ 1. All the operators are properly trained to safely operate an electrostatic, waterborne, air spray system as instructed in this manual and the voltage isolation system manual.
18 308584 Operation Operating the Spray Gun W ARNING FIRE AND EXPLOSION HAZARD T o reduce the risk of fire and explosion, only use this equipment to spray non- flammable, waterborne fluids as defined on the front cover of this manual. W ARNING ELECTRIC SHOCK HAZARD Contact with the charged components of the spray gun will cause an electric shock.
308584 19 Operation 7. Set the atomizing air valve (R) about 1.5 turns out for most applications. The Atomizing Air V alve Adjustment chart shows the effect of the atomiz- ing air valve adjustment on the air cap air flow . 8. Adjust the pattern width with the fan air valve (P).
20 308584 Operation Shutdown W ARNING PRESSURIZED EQUIPMENT HAZARD T o reduce the risk of an injury , follow the Pressure Relief Procedure on page 16 whenever you stop spraying and whenever you are instructed to relieve pressure. 1. Relieve the pressure.
308584 21 Maintenance Clean the Air Cap and Fluid Nozzle Equipment needed: Soft bristle brush Non-flammable cleaning fluid CAUTION Do not use metal tools to clean the air cap or fluid nozzle holes as this could scratch them, and make sure the electrode wire is not damaged.
22 308584 T roubleshooting W ARNING ELECTRIC SHOCK HAZARD Installing and servicing this equipment requires access to parts which may cause an electric shock or other serious injury if the work is not performed properly . Do not install or service this equipment unless you are trained and qualified.
308584 23 T roubleshooting V oltage Loss T roubleshooting (continued) 7. T o eliminate air gaps in the fluid column, spray enough fluid to purge the air out between the voltage isolation system and the spray gun.
24 308584 T roubleshooting V oltage Loss T roubleshooting (continued) 1 1. A dielectric breakdown is most likely in one of the following three areas.
