Serial #21102 1 Electrostatic Technology, Inc. 3 FlexiCoat® Powder Application System OPERATING PRINCIPLES 3.1 SCHEMATIC DIAGRAM OF AN ELECTROSTATIC COATER 3.2 PROCESS DESCRIPTION Powder particles are aerated in a fluidizing chamber and are electrostatically charged by ionized air forced through a porous plate at the base of the chamber. As the powder particles become charged, they repel each other to such a degree that they rise above the chamber forming a cloud or veil of charged particles. When a grounded object is placed in this cloud, or conveyed through this cloud, the charged powder particles, because of their opposite potential, are attracted to it. As the particles become attached to the object, they form a uniform coating, being more attracted to exposed areas than to those already insulated. The longer the object is exposed to the cloud, the thicker the coating becomes, until saturation eventually takes place. Coating thickness is controlled by applied voltage to the charging media and exposure time to the cloud. Because of the high voltage capability of the charging media, a sufficiently great potential exists between it and most substrates to permit even natural insulators to be coated. Unlike equipment with exposed electrodes, Electrostatic Technology, Inc.'s unique air ionization process charges the powder without permitting the powder, the object, or the operator to come in contact with the charging media. 2 Serial #21102 Electrostatic Technology, Inc. 4 FlexiCoat® Powder Application System GENERAL SAFETY 4.1 INTRODUCTION This section contains general study instructions for using your Electrostatic Technology, Inc.

A 1/2 inch air supply line should be connected to the fitting on the left front leg of the Powder Collector of the FlexiCoat® Powder Application System. It is strongly recommended that the air supply to be connected to the FlexiCoat® Powder Application System be clean, dry and free of particles or oil. This is most important in order to keep the powder free flowing and keep it from agglomerating which would have an adverse affect on fluidization and application. 5.1.2 Electrical 115 Volts, 60 Hertz, 1-Phase, 20 Amp circuit is required (an eight foot cord with a three wire duplex plug is provided). IMPORTANT: Serial #21102 Provide a proper ground connection for the plug equipment ground wire. Polarity of the receptacle must be according to code. 11 Electrostatic Technology, Inc. 6 FlexiCoat® Powder Application System DESCRIPTION OF COMPONENTS 6.1 FLEXICOAT® COATING STATION The coating machine is complete with Coating Bed, High Voltage Multiplier, Air Flow Meter, and cloud containing Hood. The coating chamber is of a patented design that insures that neither powder, substrate being processed, nor foreign objects can contact the charging media. 6.2 FLEXICOAT® POWDER COLLECTOR The FlexiCoat® Powder Collector consists of the following: 6.2.1 500 CFM Powder Collector Module The 500 CFM Powder Collector Module uses a ¾ HP motor to drive the Exhaust Fan. The Exhaust Fan pulls air from Powder Application Hood (Canopy) and into the (2) Cartridge Filters. The air passes through the Cartridge Filters and is forced through the Final Filter. The clean, powder free air is returned to the surroundings. Excess powder (not adhering to the parts) is carried by the air flowing through the Hood to the Cartridge Filters, where it collects on the outer surfaces. When activated, the pulse valves force air from the Pulse Valve Air Manifold through the Cartridge Filter in the opposite direction of normal flow. The pulse airflow cleans accumulated powder from the Cartridge Filter media. The powder falls to the bottom of the Collector Module and into the storage container (5 gallon pail) where it can be recovered and recycled or discarded. A Differential Pressure Gauge is located on the side of the Collector Module. This gauge provides an indication of cleanliness of the Filter Cartridges. A normal reading would be between 0 and 3.5. A reading above 3.5 would indicate the Filter Cartridges are not being cleaned well enough. This would require resetting the unit so the reverse cleaning pulses are more frequent and/or increasing the air pressure to the pulse circuit. 6.3 SURECOAT MANUAL SPRAY GUN WITH CUP FEED Refer to Nordson Manufacturer's information in the Appendix of this Manual for information on Operation and Controls of the Sure Coat Manual Powder Spray Gun, Sure Coat Manual Gun Control Unit and the Cup Gun Kit. 12 Serial #21102 FlexiCoat® Powder Application System Electrostatic Technology, Inc. 7 INSTALLATION These instructions for installing, operating and maintaining the FlexiCoat® Powder Application System must be followed for its safe and efficient operation.

Serial #21102 FlexiCoat® Powder Application System Electrostatic Technology, Inc. 12 MAINTENANCE 12.1 GENERAL A systemic maintenance schedule should be set up and adhered to in order to insure optimum machine operation. Daily, weekly, and monthly schedules should be established as applicable for each part of the coating system. WARNING: ELECTRICAL VOLTAGE USED IN THIS EQUIPMENT CAN BE HAZARDOUS. MAINTENANCE SHOULD BE HANDLED BY QUALIFIED PERSONNEL. 12.1.1 High Voltage Multiplier PLEASE NOTE: Do not twist the cord that plus into the High Voltage Multiplier, the pins are very fragile and will break off. This condition will cause irreparable damage to the High Voltage Multiplier. 12.2 COMPRESSED AIR SYSTEM The importance of keeping the compressed air clean, dry and oil free cannot be overemphasized. More coating problems can be traced to failure to maintain the air filters and air dryers than any other cause. If wet compressed air enters the machine, it may result in a clogged porous plate in the Coating Bed and poor fluidization. 12.2.1 Air Line The air line that enters the Coating Machine and the Powder Collector Module should be kept clean and free of any particles, water, and oil. 12.3 COATING BED The screws holding down the Coating Bed flange to the Ionization Chamber flange should be checked periodically for tightness. Loose bolts may cause geysers of rising powder and non-uniform fluidization. The Porous Plate is the key factor in controlling the powder cloud in the fluidic bed. Under normal operation, the powder on the plate will be uniformly fluidized (lightly bubbling) over the entire surface of the plate. If the fluidization is not uniform, the Porous Plate has become clogged and will have to be replaced. The Porous Plate will require periodic replacement depending upon hours of use, contaminants in the compressed air, and conditions of operation and cleaning. Serial #21102 25 FlexiCoat® Powder Application System Electrostatic Technology, Inc. 12.3 COATING BED (continued) CAUTION: THE UNIFORM POROSITY OF THE POROUS PLATE IS VERY IMPORTANT TO PROPER COATING. DO NOT SCRAPE OR EVEN TOUCH IT WITH A HARD OR SHARP OBJECT. NEVER POINT AN AIR GUN DIRECTLY AT THE PLATE. Clogging of the pores of the plate is the most common cause of failure. Once the Porous Plate has been removed, inspect it to determine which of the following reasons caused clogging: • Leaving powder unused in the bed for an extended period of time during humid conditions. • Oil or water in air supply system. • Damage from scratching, gouging or denting the plate. • Blowing compressed air directly at the surface of the plate. • Correct the cause of plate failure and avoid conditions in the future which may have lead to it. Order a new Porous Plate and gasket material from ETI and carefully install. 12.3.1 Porous Plate Replacement Step 1 - Turn System "OFF" by turning the POWDER COLLECTOR Switch "OFF". Step 2 - Vacuum all the powder from the bed using a soft brush fitting or rubber nozzle on the end of a vacuum hose. Step 3 - Disconnect the electric plug from the voltage multiplier. CAUTION: Pull the electrical plug straight down to disconnect it from the voltage multiplier. The plug will be damaged if it is twisted during removal. 26 Step 4 - Disconnect the poly-flo tubing from the air inlet elbow. Step 5 - Remove the (6) hex head screws and hex nuts securing the upper Fluidizing Bed Assembly flange to the lower Ionization Chamber flange. Carefully remove the lower Ionization Chamber (with Porous Plate on top) and move it to a clean workspace. Step 6 - Remove the Porous Plate and discard it. Serial #21102 FlexiCoat® Powder Application System Electrostatic Technology, Inc. 12.3.1 Porous Plate Replacement (continued) Serial #21102 Step 7 - Clean electrostatic powder out of the charging media chamber and off the charging media if required. Note that the Porous Plate must not have been properly sealed if there is powder in the charging media chamber. Step 8 - Apply gasket material along top edge of the new Porous Plate and on the flanges of the upper Fluidizing Bed Assembly and the lower Ionization Chamber as per Drawing D300028 (Detail "B") included below. The Gasket Material is item 10 on Detail "B". Step 9 - Place the new Porous Plate on top of the lower Ionization Chamber. Step 10 - Place the Ionization Chamber (with new Porous Plate) back in position, lining up the holes in the mounting flange with those in the fluidizing bed flange. Secure them with the hex head screws, flat washers and nuts. Tighten the nuts in an alternating pattern to evenly compress the gasket material and tighten down evenly so that the Porous Plate is compressed tightly between the flanges to prevent ionized air leakage around edges of the Porous Plate. Step 11 - Connect the poly-flo tubing to the air inlet elbow. Step 12 - Connect the electrical plug to the voltage multiplier. Step 13 - Restore the system to normal position. Step 14 - Add a suitable Electrostatic Fluidized Bed coating powder to the Coating Bed. 27 FlexiCoat® Powder Application System Electrostatic Technology, Inc. 12.4 POWDER COLLECTOR MODULE 12.4.1 Cartridge Filters Inspect the cartridge filters for damage to the filter media or gaskets. Remove the Final Filter and inspect the Collector Module for powder leaks. If powder is leaking past the cartridge filter gaskets, tighten the wing nuts on the cartridge filters to compress the gaskets and stop the leaks. Replace the cartridge filters if necessary. Check the differential pressure gauge. Under normal operation, the pressure should remain under 3.5 inches water column. If the reading reaches 3.5 or higher, the cartridge filters are clogged and must be pulsed. If the differential pressure gauge still reads 3.5 or higher after pulsing, replace the cartridge filters. 12.4.1.1 Filter Cartridge Replacement All cartridge filters are accessible through the filter access panel. The filter closest to the filter access panel (outside filter) must be removed in order to access the filter that is furthest from the filter access panel. Step 1 - Remove the hex head bolts, lock washers and flat washers securing the filter access panel to the Powder Collector Module. Remove the filter access panel. Step 2 - Remove the protective cap from the threaded end of the hanger rod. Step 3 - While supporting the bottom of the outside cartridge filter with one hand, remove the wing nut and flat washer securing the cartridge filter to the hanger rod. Remove the cartridge filter (and discard it). Step 4 - Remove the hanger rod from the hook in the upper collector module. Step 5 - repeat Step 2 to remove the inside cartridge filter, leaving its hanger rod in place on the hook. Step 6 - Remove the new cartridge filters form their cartons and inspect them for damage. Do not use damaged cartridge filters. Step 7 - Guide the installed hanger rod through the open end of the cartridge filter. Guide the threaded end of the hanger rod through the hole in the closed end of the cartridge filter. Step 8 - Secure the cartridge filter and hanger rod to the collector module using the flat washer and wing nut. Tighten the wing nut until the cartridge filter gasket is compressed evenly. 28 Serial #21102 FlexiCoat® Powder Application System Electrostatic Technology, Inc. 12.4.1.1 Filter Cartridge Replacement (continued) Step 9 - Install a protective cap over the threads of the hanger rod. Step 10 - Hang the outside hanger rod on its hook and repeat Steps 24 to install the outside cartridge filter. Step 11 - Secure the filter access panel to the collector module using the flat washers and hex head bolts. 12.4.2 Final Filter Visually inspect the Final Filter whenever replacing the cartridge filters. Replace the Final Filter when it becomes clogged and negatively affects performance of the exhaust fan. 12.4.2.1 Final Filter Replacement Step 1 - Remove the hex nuts and lock washers securing the Zbrackets to the collector module. Step 2 - Remove the old final filter from the collector module. Step 3 - Remove the new final filter from its carton and inspect it for damage. Do not use a damaged final filter.
