Any approvals obtained for Nordson equipment will be voided if instructions for installation, operation, and service are not followed.

2 Circulating and Non-Circulating Color Change Manifolds Personal Safety To prevent injury follow these instructions. Do not operate or service equipment unless you are qualified. Do not operate equipment unless safety guards, doors, or covers are intact and automatic interlocks are operating properly. Do not bypass or disarm any safety devices. Keep clear of moving equipment. Before adjusting or servicing moving equipment, shut off the power supply and wait until the equipment comes to a complete stop. Lock out power and secure the equipment to prevent unexpected movement. Relieve (bleed off) hydraulic and pneumatic pressure before adjusting or servicing pressurized systems or components. Disconnect, lock out, and tag switches before servicing electrical equipment. While operating manual spray guns, make sure you are grounded. Wear electrically conductive gloves or a grounding strap connected to the gun handle or other true earth ground. Do not wear or carry metallic objects such as jewelry or tools. If you receive even a slight electrical shock, shut down all electrical or electrostatic equipment immediately. Do not restart the equipment until the problem has been identified and corrected. Obtain and read Material Safety Data Sheets (MSDS) for all materials used. Follow the manufacturer s instructions for safe handling and use of materials, and use recommended personal protection devices. Make sure the spray area is adequately ventilated. To prevent injury, be aware of less-obvious dangers in the workplace that often cannot be completely eliminated, such as hot surfaces, sharp edges, energized electrical circuits, and moving parts that cannot be enclosed or otherwise guarded for practical reasons.

Circulating and Non-Circulating Color Change Manifolds 3 High-Pressure Fluids High-pressure fluids, unless they are safely contained, are extremely hazardous. Always relieve fluid pressure before adjusting or servicing high pressure equipment. A jet of high-pressure fluid can cut like a knife and cause serious bodily injury, amputation, or death. Fluids penetrating the skin can also cause toxic poisoning. If you suffer a fluid injection injury, seek medical care immediately. If possible, provide a copy of the MSDS for the injected fluid to the health care provider. The National Spray Equipment Manufacturers Association has created a wallet card that you should carry when you are operating high-pressure spray equipment. These cards are supplied with your equipment. The following is the text of this card: WARNING: Any injury caused by high pressure liquid can be serious. If you are injured or even suspect an injury: Go to an emergency room immediately. Tell the doctor that you suspect an injection injury. Show him this card. Tell him what kind of material you were spraying. MEDICAL ALERT AIRLESS SPRAY WOUNDS: NOTE TO PHYSICIAN Injection in the skin is a serious traumatic injury. It is important to treat the injury surgically as soon as possible. Do not delay treatment to research toxicity. Toxicity is a concern with some exotic coatings injected directly into the bloodstream. Consultation with a plastic surgeon or a reconstructive hand surgeon may be advisable. The seriousness of the wound depends on where the injury is on the body, whether the substance hit something on its way in and deflected causing more damage, and many other variables including skin microflora residing in the paint or gun which are blasted into the wound. If the injected paint contains acrylic latex and titanium dioxide that damage the tissue s resistance to infection, bacterial growth will flourish. The treatment that doctors recommend for an injection injury to the hand includes immediate decompression of the closed vascular compartments of the hand to release the underlying tissue distended by the injected paint, judicious wound debridement, and immediate antibiotic treatment.

4 Circulating and Non-Circulating Color Change Manifolds Fire Safety To avoid a fire or explosion, follow these instructions. Ground all conductive equipment in the spray area. Use only grounded air and fluid hoses. Check equipment and workpiece grounding devices regularly. Resistance to ground must not exceed one megohm. Shut down all equipment immediately if you notice static sparking or arcing. Do not restart the equipment until the cause has been identified and corrected. Do not smoke, weld, grind, or use open flames where flammable materials are being used or stored. Do not heat materials to temperatures above those recommended by the manufacturer. Make sure heat monitoring and limiting devices are working properly. Provide adequate ventilation to prevent dangerous concentrations of volatile particles or vapors. Refer to local codes or your material MSDS for guidance. Do not disconnect live electrical circuits while working with flammable materials. Shut off power at a disconnect switch first to prevent sparking. Know where emergency stop buttons, shutoff valves, and fire extinguishers are located. If a fire starts in a spray booth, immediately shut off the spray system and exhaust fans. Shut off electrostatic power and ground the charging system before adjusting, cleaning, or repairing electrostatic equipment. Clean, maintain, test, and repair equipment according to the instructions in your equipment documentation. Use only replacement parts that are designed for use with original equipment. Contact your Nordson representative for parts information and advice.

Circulating and Non-Circulating Color Change Manifolds 5 Halogenated Hydrocarbon Solvent Hazards Do not use halogenated hydrocarbon solvents in a pressurized system that contains aluminum components. Under pressure, these solvents can react with aluminum and explode, causing injury, death, or property damage. Halogenated hydrocarbon solvents contain one or more of the following elements: Element Symbol Prefix Fluorine F Fluoro- Chlorine Cl Chloro- Bromine Br Bromo- Iodine I Iodo- Check your material MSDS or contact your material supplier for more information. If you must use halogenated hydrocarbon solvents, contact your Nordson representative for information about compatible Nordson components. Action in the Event of a Malfunction If a system or any equipment in a system malfunctions, shut off the system immediately and perform the following steps: Disconnect and lock out system electrical power. Close hydraulic and pneumatic shutoff valves and relieve pressures. Identify the reason for the malfunction and correct it before restarting the system. Disposal Dispose of equipment and materials used in operation and servicing according to local codes. 2. Description The color change manifold provides quick color changes with minimum coating loss. The manifold is available in circulating and non-circulating models. The manifold is modular, making it expandable and easy to maintain. The manifold valves are air-actuated, allowing the color change manifold to be mounted in a hazardous area with no ignition risk.

6 Circulating and Non-Circulating Color Change Manifolds Non-Circulating (Dead-Ended) Manifold See Figure. The basic non-circulating (dead-ended) color change manifold consists of four identical valves mounted on a manifold block (). Coating material may be circulated through the valves and manifold, but is dead-ended to the spray devices. Two of these valves are used for coating material (4, 5), one is used for solvent (3), and one may be used to air-push old coating material and/or solvent from the system (2). The air-push option is useful in lowering solvent waste and emissions. If the air-push option is not used, this valve may be used to dispense an additional coating. 3 2 4 5 062400A Fig. Non-Circulating Manifold. Manifold block 2. Air push valve 3. Solvent valve 4. Coating valve (color #2) 5. Coating valve (color #) Circulating Manifold See Figure 2. The basic circulating color change manifold consists of nine identical valves. Two sets of three valves are used for coating material (4, 5). One valve is used for solvent (3). One valve is used to dump coating material and/or solvent (6). The remaining valve may be used to air-push coating material and/or solvent from the system (2). The two valves opposite the coating valves allow the coating material to be circulated through a closed-loop hydraulic circuit, through the paint lines, heaters, and back to the supply, allowing the paint to be heated as it circulates. Two valves allow for return from the guns on a circulating system. The remaining valve serves as a dump valve (6) to clear paint from the lines before a color change.

Coating valves (color #) 6. Dump valve Upgrading Because of the manifold s modular design, additional color valve modules may be added to the end of an existing manifold in either a circulating or non-circulating system. There is no limit to the number of color modules which may be added. Theory of Operation The following paragraphs explain the theory of operation for the circulating and non-circulating color change manifolds. Non-Circulating (Dead-Ended) Manifold See Figure 3. Pressurized coating material is connected to the material supply elbow () on the paint valve. When air is applied, an air piston within the paint valve is lifted. The rising piston lifts the needle from the seat, allowing coating material to exit the valve, enter the manifold (3), and pass out to the spray device. The spray device may then be triggered and coating material may be applied to the substrate.

8 Circulating and Non-Circulating Color Change Manifolds Non-Circulating (Dead-Ended) Manifold (contd) When air is removed, the needle is pushed back into the seat, stopping the coating material flow into the manifold. In the standard configuration of the valve, a material return elbow (2) is installed on the opposite side of the valve. This configuration allows the pressurized coating material to circulate through the valve and return to the supply. In a heated system, this allows heated coating material to circulate in a closed loop through the valve body for better temperature control. The material return elbow may be removed and replaced with a pipe plug, making the coating supply system dead-ended. 2 2 3 3 Standby Active Fig. 3 Non-Circulating Manifold Schematic. Material supply elbow 2. Material return elbow 3. Manifold 0624003A Circulating Manifold See Figure 4. Pressurized coating material is connected to the material supply elbow () on valve A. When air is applied to valve A, an air piston within the valve is lifted. The rising piston lifts the needle from the seat, allowing paint to exit the valve, enter the material supply manifold (2), and pass out to circulating spray devices. The spray devices may then be triggered and paint may be applied to the substrate.

Circulating and Non-Circulating Color Change Manifolds 9 Some of the coating material passes through the spray devices and to the substrate, and some circulates through the spray device and returns to the material return manifold (3) where it is stopped by the closed valve C. When air is applied to valve C, the circulating coating material passes through the valve and returns to the supply through the material return elbow (4). This completes the active circuit, meaning that when both valves A and C are opened, the coating material is actively circulating through the guns. While one color in the manifold is active, the second color is standing by. In the standby mode, valve A is closed and valve B is open, allowing the coating material to circulate in a closed-loop system from the supply, heaters, filter, etc. and return to the pump. This allows additional colors to circulate in preparation for a color change, providing control of painting quality. 2 2 3 4 3 4 Standby Active Fig. 4 Circulating Manifold Schematic.
