6 Manual Page l-2 Temperature Controller SAFETY DURING INSTALLATION Electrical. A protective electrical ground connection to a reliable earth ground is essential for safe operation. Without one, all accessible conductive components (including knobs and controls that appear insulated) can render an electric shock. SAFETY DURING OPERATION 2. A disconnect switch with lockout capability must be provided between the power source and the equipment. 3. The power supply wire gauge and insulation must be sufficient to meet the temperature and power requirements. 4. Only fuses of the correct type voltage rating and current rating should be used. Refer to the Nordson equipment parts list for fuse recommendations. Using incorrect or nonrecommended fuses can present a fire hazard. DO NOT operate Nordson equipment under the following conditions:. At a pressure higher than the rated maximum working pressure of any component in the system. 2. Near volatile or otherwise explosive gases or materials. 3. Without the covers, panel and safety guards properly installed. 4. At atmospheric temperatures below 20 F (-6 C) or above 20 F (50 C). 5. With hoses enclosed in any material that interferes with heat dissipation. This includes electrical conduit, insulation of any type or tight metal covers. 6. With large areas of hose in contact with a cold floor, cold supports or other such surfaces. Cold points along the hose restrict the flow of adhesive inside the hose and can create potential problems during operations. Issued CORPORATION 988 Pub. No A

7 Temperature Controller Manual Page l-3 7. In drafty areas with the applicator guns unshielded from the draft. Rapid heat dissipation due to air movement across the guns may cause operational problems. 8. (If a handgun is used) with the handgun trigger left unlocked while the gun is unattended. in addition: SAFETY DURING SERVICING. Use only the metal base when attempting to lift or move an applicator. DO NOT use equipment covers, doors, panels or hose connectors as braces or grips. 2. NEVER use Nordson equipment as a ladder or stepping stool. 3. Route all hoses to prevent damage from kinking, abrasion and other physical damage. DO NOT allow a hose to be installed with a bend radius of less than 6 inches (50 mm). 4. NEVER point an applicator handgun at yourself or anyone else.. DO NOT perform internal service or adjustment on any equipment unless another person capable of rendering first aid and resuscitation is present. 2. Only qualified personnel should service Nordson equipment. 3. To avoid personal injury, never touch exposed connections and components while power is ON. Dangerous voltages exist at several points in the equipment. 4. Disconnect, lock out and tag external electrical power before removing protective panels or replacing electrical components. 5. Remove all jewelry (rings, watches, etc.) before servicing equipment. 6. If possible, stand on a rubber mat when servicing Nordson equipment. DO NOT work on equipment if standing water is present. Avoid working in a high-humidity atmosphere. Cover exposed terminals and work areas with rubber sheeting to avoid accidental contact while the Dower is ON. Pub.

8 Manua46-69 Page-4 Temperature Controller 7. Always wear safety glasses, protective gloves (Nordson P/N ) or equivalent and long-sleeved protective clothing to prevent injury from hot applicator parts, splashed hot melt adhesive and hot gun surfaces. 8. To prevent serious injury from molten adhesive under pressure, always relieve system hydraulic pressure (by triggering the gun, for example) before opening any hydraulic fitting or connection. 9. NEVER use an open torch, drill or broach when cleaning a nozzle. 0. NEVER operate equipment with a known leak in the system. SAFETY WHEN USING HOT MELT ADHESIVES AND SOLVENTS Hot Melt Adhesives. Use extreme care when working with molten material. They solidify rapidly at high temperatures and present a hazard. Severe burns can occur if the molten materials come in contact with the skin. Even when first solidified, they are still hot. 2. Always wear protective clothing and eye protection when handling molten material or working near equipment containing hot melt adhesives under pressure. 3. IF MOLTEN MATERIAL COMES IN CONTACT WITH THE SKIN. DO NOT try to remove molten material from the skin. Immediately immerse the affected area in cold, clean water. Keep the affected areas immersed until the material has cooled. DO NOT try to remove the cooled material from the skin. Cover the affected area with a clean, wet compress. In cases of severe burns, look for signs of shock. If shock is suspected, have patient lie down, use a blanket to preserve body heat and elevate the feet several inches. Call a physician immediately. issued l/88 BNORDSON CORPORATION 988 Pub.No. 0797A

9 Temperature Controller Manual Page l-5 Heat Solvents. DO NOT use an open flame or uncontrolled heating device to heat solvents (for example, a small pan on an unregulated hot plate). 2. Avoid fire hazard by using a controlled heating device to heat solvents (for example, a small deep fat fryer or thermostatically controlled hot plate). 3. DO NOT USE PAINT-TYPE SOLVENTS UNDER ANY CIR- CUMSTANCES! These solvents are volatile and may be a fire and/or toxic-vapor hazard even at room temperature. 4. Always be sure the work area is adequately ventilated. Avoid prolonged or repeated breathing of solvent vapors. 5. Halogenated Hydrocarbon Solvents are dangerous when used to clean aluminum components in a pressurized fluid system. No available stabilizers prevent halogenated hydrocarbon solvents from reacting under all conditions with aluminum components in a pressurized fluid pumping system. 6. NEVER clean any aluminum component or flush any system using halogenated hydrocarbon solvents. Use Type R (P/N ) solvents or contact your solvent or hot melt supplier for a non-halogenated hydrocarbon solvent for cleaning and flushing. Halogenated fluids include the following solvents: Fluorinated Solvents: Dichlorofluoromethane Trichlorofluoromethane Chlorinated Solvents: Carbon Tetrachloride Chloroform Dichloromethane Ethlylene Dichloride Methylene Chloride Monochlorobenzene Monchlorotoluene Orthodichlorobenzene Pub.
