Air Supply Operating Environment 1. Type of fluids Please consult with SMC when using the product in applications other than compressed air. Regarding products for general fluids, please contact SMC concerning applicable fluids. 2. When there is a large amount of drainage. Compressed air containing a large amount of drainage can cause malfunction of pneumatic equipment. An air dryer or water separator should be installed upstream from filters. 3. Drain flushing If condensation in the drain bowl is not emptied on a regular basis, the bowl will overflow and allow the condensation to enter the compressed air lines. It causes malfunction of pneumatic equipment. If the drain bowl is difficult to check and remove, installation of a drain bowl with an auto drain option is recommended. For details on the above compressed air quality, refer to SMC Best Pneumatics catalog. 4. Use clean air. Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction. 5. Do not use the ordinary fittings and tubing in locations where static electricity would be problematic. It may result in the system failure and trouble. In such places, use of antistatic fittings (Series KA) and antistatic tubing (Series TA) are recommended. 6. Do not use the ordinary fittings and tubing in locations where spatter is generated. Spattering may result in a fire hazard. In such a place, use of flame resistant fittings (Series KR/KRM) and flame resistant tubing (Series TRS/TRB/TRBU/TRTU) are recommended. 7. Do not use in an environment where the product is directly exposed to cutting oil, lubricant, coolant oil, etc. Please contact SMC if using for an environment exposed to cutting oil, lubricant or coolant oil, etc. 8. Take note that if nylon tubing, soft nylon tubing and antistatic tubing are used in a clean room. The antioxidant on the surface of the soft nylon tubing may come off, thereby lowering the cleanness level. 9. Do not use in environments where foreign matter may stick to the product or get mixed in the product’s interior. This may cause leakage or disconnection of the tubing. 1. Install an air filter. Install an air filter at the upstream side of valve. Select an air filter with a filtration degree of 5 μm or finer. 2. Install an after-cooler, air dryer or water droplet separator, etc. Compressed air that contains a large amount of drainage can cause malfunction of pneumatic equipment. Therefore, take appropriate measures to ensure air quality, such as by providing an aftercooler, air dryer, or water droplet separator. 3. Ensure that the fluid and ambient temperature are within the specified range. If the fluid temperature is 5°C or less, the moisture in the circuit could freeze, causing damage to the seals and leading to equipment malfunction. Therefore, take appropriate measures to prevent freezing. For details on the above compressed air quality, refer to SMC Best Pneumatics catalog. Operating Environment 1. Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these. Refer to each construction drawing on the fittings and tubing material. 2. Do not expose the product to direct sunlight for an extended period of time. 3. Do not use in a place subject to heavy vibration and/or shock. 4. Do not mount the product in locations where it is exposed to radiant heat. Maintenance 1. Perform maintenance inspection according to the procedures indicated in the operation manual. If handled improperly, malfunction and damage of machinery or equipment may occur. 2. Maintenance work If handled improperly, compressed air can be dangerous. Assembly, handling, repair and element replacement of pneumatic systems should be performed by a knowledgeable and experienced person. 3. Drain flushing Remove drainage from air filters regularly. 4. Removal of equipment, and supply/exhaust of compressed air When components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut off the supply pressure and electric power, and exhaust all compressed air from the system using the residual pressure release function. When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent cylinders from sudden movement. Fittings & Tubing Precautions 2 Be sure to read this before handling. Warning Warning Warning Warning Caution 45 A
