Caution 1. When using a 2-unit combination such as the AC�ｭ0A, AC�ｭ0B and AC�ｭ0D, secure the top and bottom of the bracket. For 3-unit, securing the bottom side of the bracket is recommended. 2. The bracket position varies depending on the attachment (T-interface or pressure switch) mounting. 3. The standard mounting position for a bracket is OUT side of each component (the AF, AR, AL, AW and AFM). For the standard mounting position dimension for a bracket by mounting an attachment, refer to Best Pneumatics No. 5. 4. A bracket cannot be mounted on both sides of a T-interface or a pressure switch. 5. Please contact SMC if you wish to change the bracket mounting position. Design/Selection Air Combination Warning 1. To prevent damage to the element, replace the element every 2 years or when the pressure drop becomes 0.1 MPa, whichever comes first. 2. Release accumulated condensation inside of an air filter case periodically and before the accumulation reaches the maximum capacity. If accumulated condensation flows out to the outlet side, it can cause malfunction. Maintenance Air Filter Caution 1. Design the system so that a mist separator and a micro mist separator are installed where a pulsation is not likely to be generated. The pressure difference between the internal and external pressure inside the element should be kept within 0.1 MPa, since exceeding this value can cause damage. Design/Selection Mist Separator/Micro Mist Separator Maintenance Warning 1. To prevent damage to the filter element, replace it every 2 years or when the pressure drop becomes 0.1 MPa, whichever comes first. 2. Release accumulated condensation inside of an air filter bowl periodically and before the accumulation reaches the maximum capacity. If accumulated condensation flows out to the outlet side, it can cause malfunction. Maintenance Caution 1. Turn the knob counterclockwise to release the drainage manually. Avoid applying excessive torque to the knob, such as by using a tool, as this can damage an auto drain. After releasing the condensation, turn the knob clockwise until it stops. 2. Air leakage or other performance malfunction can occur if premature clogging of the element or pressure drop causes the pressure inside the bowl to deviate from the specified pressure range parameters. Check the pressure whenever such an irregularity occurs. Warning 1. Use an auto drain under the following conditions to avoid malfunction. . Operating compressor: 0.75 kW (100 L/min. (ANR)) or more When using 2 or more auto drains, multiply the above value by the number of auto drains to find the minimum capacity of the required compressors. Selecting a model with a minimum or larger required capacity is recommended. For example, when using 2 auto drains, a compressor capacity of at least 1.5 kW (200 L/min. (ANR)) is required. . Operating pressure: 0.1 MPa or more . Operating pressure for AD17/27: 0.1 MPa or more Operating pressure for AD37/47: 0.15 MPa or more Design/Selection Float Type Auto Drain Piping Caution 1. Float type auto drain Drain piping should be performed under the following conditions to avoid malfunction. . Use piping whose I.D. is o6.5 or larger, and whose length is 5 m or less. Avoid riser piping. . AD17/27: Use piping with an I.D. of o2.5 or larger. AD37/47: Use piping with an I.D. of o4 or larger. Length is 5 m or less. Avoid riser piping. F.R.L.
