7 Safety 1-1 Section 1 Safety Introduction Read and follow these safety instructions. Task- and equipment-specific warnings, cautions, and instructions are included in equipment documentation where appropriate. Make sure all equipment documentation, including these instructions, is accessible to all persons operating or servicing equipment. Qualified Personnel Equipment owners are responsible for making sure that Nordson equipment is installed, operated, and serviced by qualified personnel. Qualified personnel are those employees or contractors who are trained to safely perform their assigned tasks. They are familiar with all relevant safety rules and regulations and are physically capable of performing their assigned tasks. Intended Use Use of Nordson equipment in ways other than those described in the documentation supplied with the equipment may result in injury to persons or damage to property. Some examples of unintended use of equipment include using incompatible materials making unauthorized modifications removing or bypassing safety guards or interlocks using incompatible or damaged parts using unapproved auxiliary equipment operating equipment in excess of maximum ratings 2010 Nordson Corporation

8 1-2 Safety Regulations and Approvals Make sure all equipment is rated and approved for the environment in which it is used. Any approvals obtained for Nordson equipment will be voided if instructions for installation, operation, and service are not followed. All phases of equipment installation must comply with all federal, state, and local codes. Personal Safety Fire 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 any 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. 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. 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. To avoid a fire or explosion, follow these instructions. Do not smoke, weld, grind, or use open flames where flammable materials are being used or stored. Provide adequate ventilation to prevent dangerous concentrations of volatile materials 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 Nordson Corporation

9 Safety 1-3 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. 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. Grounding WARNING: Operating faulty electrostatic equipment is hazardous and can cause electrocution, fire, or explosion. Make resistance checks part of your periodic maintenance program. If you receive even a slight electrical shock or notice static sparking or arcing, shut down all electrical or electrostatic equipment immediately. Do not restart the equipment until the problem has been identified and corrected. Grounding inside and around the booth openings must comply with NFPA requirements for Class 2, Division 1 or 2 Hazardous Locations. Refer to NFPA 33, NFPA 70 (NEC articles 500, 502, and 516), and NFPA 77, latest conditions. All electrically conductive objects in the spray areas shall be electrically connected to ground with a resistance of not more than 1 megohm as measured with an instrument that applies at least 500 volts to the circuit being evaluated. Equipment to be grounded includes, but is not limited to, the floor of the spray area, operator platforms, hoppers, photoeye supports, and blow-off nozzles. Personnel working in the spray area must be grounded. There is a possible ignition potential from the charged human body. Personnel standing on a painted surface, such as an operator platform, or wearing non-conductive shoes, are not grounded. Personnel must wear shoes with conductive soles or use a ground strap to maintain a connection to ground when working with or around electrostatic equipment. Operators must maintain skin-to-handle contact between their hand and the gun handle to prevent shocks while operating manual electrostatic spray guns. If gloves must be worn, cut away the palm or fingers, wear electrically conductive gloves, or wear a grounding strap connected to the gun handle or other true earth ground. Shut off electrostatic power supplies and ground gun electrodes before making adjustments or cleaning powder spray guns. Connect all disconnected equipment, ground cables, and wires after servicing equipment Nordson Corporation

10 1-4 Safety 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 electrical power. Close pneumatic shutoff valves and relieve pressures. Identify the reason for the malfunction and correct it before restarting the equipment. Disposal Dispose of equipment and materials used in operation and servicing according to local codes Nordson Corporation

13 Installation 3-1 Section 3 Installation WARNING: Allow only qualified personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation. Transport Transport the unit so as to avoid damage. Use suitable packaging materials. Protect the unit from humidity, large temperature fluctuations (condensation), dust and vibrations. Unpacking Unpack the unit carefully to avoid damage. Inspect for any damage caused during transport. Save packing materials for possible later use, or otherwise dispose of properly according to local regulations. Storage Use suitable packaging materials. Protect the unit from humidity, large temperature fluctuations (condensation), dust and vibrations. Preparing for Installation NOTE: Booths are generally delivered flat pack for on site assembly. NOTE: Installation of the booth should not be undertaken without the presence of a Nordson representative or a suitably qualified person. 1. Choose a level site on which to install the ColorMax Booth, away from drafts or any other airborne contaminates. 2. Seal concrete floors with a suitable material to avoid dust. Other floor surfaces should be of a type that is easy to keep clean. 2010Nordson Corporation

14 3-2 Installation Electrical Connection WARNING: Risk of electrical shock. Disconnect and lock out input power to equipment before servicing. Failure to observe this warning may result in personal injury or death. A single supply cable is required to the booth control panel. The supply should be fed from a suitable disconnect device. Introduce the cable into the panel using an IP6X cable gland. Ensure that all the electrical wires are suitably sized for the fan motor loading and adequate fuse/circuit protection is provided at the source of supply. Consult electrical schematic drawings for on site conditions and refer to engineering design. Pneumatic Connection WARNING: The air supply pressure should be set to 4 bar (maximum) and should only be modified by a Nordson technician. Connect the air supply to the booth pneumatic panel and ensure that the air supply is of the required quality. Also check that the air has been discharged from the system via the tank inlet filter to ensure that any material left in the line during installation does not enter the system. Disassembly To disassemble the unit, turn the unit off and remove the air and power supplies. Disposal Dispose of properly according to local regulations. 2010Nordson Corporation
