CERJET® p 1 Preface Thank you for purchasing the Spray Nozzle from H. Ikeuchi & Co., Ltd. This manual gives detailed instructions for the basic handling, maintenance and cautions of the product. Please be aware that due to continuing efforts to improve our products, some details in this manual may differ from the actual product. After reading, keep this manual handy for quick reference. Safety Precautions Prior to use, read this manual carefully and familiarize yourself with the proper operation of the product for optimal performance. H. Ikeuchi & Co., Ltd. takes no responsibility for any accidents and/or injuries resulting from improper handling, installation and/or operation. Wear safety gloves. CAUTION Screw threads, edges and corners may be sharp and could cause injury. Ensure that the nozzle is firmly installed. CAUTION Loose screws may cause the nozzle to come off during operation and lead to serious accidents. Be aware of the nozzle temperature and do not perform CAUTION maintenance until it has cooled down enough to avoid burns. H. Ikeuchi & Co., Ltd. CERJET® p 2 1. Suggestions & Cautions (1) Nozzle must be dismantled and stored if it is not used for an extended period of time. (2) Avoid prolonged exposure of the nozzle to high temperatures when not in use to prevent corrosion. (3) Even when the installed nozzles are not in use, it is recommended to maintain a constant air supply at a pressure of 5 kPa, to protect nozzles from high temperature and dust accumulation. (4) To extend the life of the nozzles, purge them with air or using other methods. CORRECT WRONG (5) Always use a flange to install the nozzles to an incinerator or cooling tower and make sure to avoid excessive force when installing. Never use anything but a flange to install the nozzles. (6) Nozzles may be heavy and need to be handled carefully. Example: If the nozzles are shipped with protectors, they need to be installed separately; first the protector and then the nozzles. Piping connections for air and water supply should be installed after the nozzles have been installed. (7) Screw threads, edges and corners may be sharp. Wearing safety gloves is recommended. (8) For BIM series with removable flange, when adjusting the flange, loosen the lock bolt and move the flange. Make sure that the nozzle is kept horizontally while adjusting the flange. (9) Operate the nozzles under the specified pressures. If the pressure is not specified, refer to the provided flow-rate diagram. (10) Avoid damaging or scratching the nozzles and pipes. When replacing a nozzle tip or disassembling the nozzle for maintenance, always use a spanner and milling vice. DO NOT use a pipe vice, pipe wrench or pliers. H. Ikeuchi & Co., Ltd. CERJET® p 3 (11) Precautions to prevent liquids from back-flowing: To start operation: Open the air supply first, then the liquid. To stop operation: Shut off the liquid first, then the air. (12) Air and liquid piping Use piping and valves large enough to prevent the pressure from dropping. Use new stainless steel pipes, as dust and debris in old pipes may clog the nozzles. Never use pipes that can rust. Even new pipes may have chips, seal tape or other debris inside. ALWAYS flush pipes thoroughly before installing nozzles to remove any debris that could cause clogging. Install pressure gauges just before the nozzle to adjust air and liquid pressures appropriately. Installation of a valve is also recommended. If a nozzle is clogged, its performance is impacted. Installing strainers helps prevent nozzle clogging. (13) Prior to shipment all parts are firmly tightened. However, due to temperature changes during transport and especially if the nozzles are exposed to repeated heating and cooling during operation, parts such as screws may loosen and should therefore be inspected regularly. Take special care when screwing in and unscrewing to prevent damage. Always apply an anti-seizing or sealing agent to the threads before assembly. H. Ikeuchi & Co., Ltd. CERJET® 2.

Consumable Note: (1) Consumables The lifetime of a nozzle varies, depending on the operational conditions. Replace consumable parts when corrosion or pitting corrosion of a nozzle tip or other parts is found and/or nozzle performance significantly deteriorates. (2) Dimensions and materials may differ depending on product codes. (3) In the material code, "S" represents "stainless steel". For example, S303 stands for stainless steel 303. H. Ikeuchi & Co., Ltd. CERJET® p 5 3. Disassembly (1) Nozzle After the nozzle has cooled down, hold the pipe adaptor (#5) in a milling vice. Loosen the cap (#3) with a spanner, and remove the nozzle adaptor (#4) with a hexagon socket wrench. Then remove the cap (#3), and take out the nozzle tip (#1) and core (#2). Necessary tools: Milling vice Spanner 12 mm Hexagon socket wrench 14 mm (2) Pipe Hold the joint (#8) in a milling vice and unscrew the plug (#9) with a spanner, then take out the O-ring P10 (#12) and O-ring P12 (#11). Necessary tools: Milling vice Spanner 27 mm Note: (1) A nozzle dismounted from an incinerator may be very hot, make sure the nozzle has cooled down sufficiently before disassembly. (2) Make sure not to drop, damage or lose any of the small parts. (3) The nozzle tip and orifice are the most important and delicate parts. Take extreme care when handling them. (4) The nozzle adaptor (#4) is thin and fragile. To disassemble, first LOOSEN but DO NOT REMOVE the cap (#3), and remove the nozzle adaptor (#4) with a hexagon socket wrench. DO NOT use a spanner to remove the nozzle adaptor (#4). 4. Assembly Assemble in the reverse order of the above 3. Disassembly. First, assemble the nozzle tip (#1), core (#2), cap (#3) and nozzle adaptor (#4) lightly, then attach the pipe adaptor (#5). Use a hexagon socket wrench. DO NOT use a spanner as it may damage the nozzle adaptor (#4). Note: (1) If the flange (#13) has been removed, reattach it before assembling joint (#8). (2) Before assembly, confirm that the sealing surfaces (indicated with above) and the orifice are clean and undamaged. (3) Remove dust and debris carefully from the orifice and sealing surfaces (indicated with above) with a brush to not damage these important surfaces. (4) Always apply anti-seizing agent to the threads (indicated with above) before assembly. H. Ikeuchi & Co., Ltd. CERJET® p 6 5. Maintenance Check Daily Spray Item Pressure gauges and flow meters Periodically Spray Appearance Connection Check points Have a visual check of the spray pattern. Confirm that the spraying pressure is normal, when spray pattern cannot be seen because nozzles are in an incinerator. Confirm that the air and liquid pressures and flow rate are correct during operation. Remove the nozzle from incinerator and visually check the spray pattern. Confirm that there is no corrosion or dust adhesion to the nozzle tip and orifice. Confirm that the cap, nozzle adaptor, and pipe adaptor are screwed tightly. 6.
