Air Supply 1. Do not use in atmospheres of corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these. 2. Do not use in direct sunlight. 3. In locations near heat sources, protect against radiated heat. 4. Do not use in locations where static electric charges will be a problem. This may cause system failure. Consult with SMC regarding use in this kind of environment. 5. Do not use in locations where spatter occurs. There is a danger of spatter causing a fire. Consult with SMC regarding use in this kind of environment. 6. Do not use in environments where there is direct contact with liquids such as cutting oil, lubricating oil, coolant oil, or paints, etc. This may cause connection and release failure and/or leakage. Consult with SMC regarding use in this kind of environment. 7. Do not use in locations influenced by vibrations or impacts. This may cause air leakage and S couplers damage. Consult with SMC regarding use in this kind of environment. 8. Do not use in an environment where foreign matter such as spatter, metal powder or sand splashes onto or enters the product. This may cause connection and release failure and/or leakage. 9. Do not use in an environment where the product is constantly exposed to water. Rust may occur. 10. When the socket and plug are stored or not in use, make sure dust does not get stuck to them. This may cause connection and release failure and/or leakage. Operating Environment Warning 1. Install an air filter. Install an air filter upstream, near the valve. Select an air filter with a filtration degree of 5 μm or finer. 2. As a countermeasure, install an aftercooler, air dryer or water separator. Compressed air containing large amounts of drainage can cause malfunction of pneumatic equipment. As a countermeasure, install an aftercooler, air dryer or water separator. 3. Ensure that the fluid and ambient temperature are within the specified range. If the fluid temperature is 5°C or below, the moisture in the circuit could freeze, causing damage to the seals and leading to equipment malfunction. Therefore, take appropriate measures to prevent freezing. Refer to SMC's “Air Preparation Equipment” catalog for further details on compressed air quality. Caution 1. Excessive drainage Compressed air containing large amounts of drainage can cause malfunction of pneumatic equipment. As a countermeasure, install an air dryer or water separator before the filter. 2. Drain flushing If the drain removal from air filter is missed, drain will be flown out to the outlet side and may result in malfunction of pneumatic equipment. When removing drain is difficult, use of a filter with an auto drain is recommended. Refer to SMC's “Air Preparation Equipment” catalog for further details on compressed air quality. 3. Use clean air. If the compressed air includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., it can cause damage or malfunction in the system. Air Supply Warning Wrapping direction Pipe tape Leave approximately one length of screw exposed. 7. S couplers with sleeve lock mechanism must be locked during operation in order to prevent sudden disconnection. 8. Install a stop valve at the supply pressure side of the socket. Emergency shutdown may not be possible without it. Mounting Warning 1. Preparation before piping Before piping is connected, it should be thoroughly blown out by air (flushed) or washed to eliminate cutting chips, cutting oil, and other debris from inside the pipe. 2. Before mounting, confirm the model and size, etc. Also, confirm that there are no blemishes, nicks or cracks in the product. 3. When connecting a pipe, consider factors such as changes in the piping length due to pressure, and allow sufficient leeway. 4. Mount so that S couplers and piping are not subjected to twisting, pulling or moment loads. This can cause damage to S couplers and flattening, bursting or disconnection of piping, etc. 5. Mount so that piping is not damaged due to tangling and abrasion. This can cause flattening, bursting or disconnection of piping, etc. 6. When screwing in the pipes or fittings, make sure to prevent cutting chips or the sealing material on the threaded portion of the pipe from entering the piping. Also, if pipe tape is used, leave about 1 thread ridge exposed at the end of the threads. Caution Series KK130 Specific Product Precautions 2 Be sure to read before handling.
