10 Air Combination Series AC10-A to AC40-A AW AL AR AFM / AFD AF Attachment AW+AFM AF+AFM+AR AF+AR AW+AL AF+AR+AL AC Lock button Specific Product Precautions Selection 1. When releasing air at the intermediate position using a T-spacer on the inlet side of the lubricator, lubricant may back flow. Therefore, releasing air that does not contain traces of lubricant is not possible. To release air that does not contain traces of lubricant, use a check valve (Series AKM) on the inlet side of the lubricator to prevent a backflow of the lubricant. 2. If a pressure relief 3 port valve is mounted on the inlet side of the lubricator, causing a backflow of air, it can result in a backflow of oil or damage to internal parts. Do not use it in this fashion. 3. An F.R.L. unit shipped from the plant has its model number labeled. However, components that are combined together during the distribution process do not have a label on them. Caution Piping 1. When mounting a check valve, make sure the arrow (IN side) points in the correct direction of air flow. Warning 1. Float type auto drain Operate 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 value above by the number of auto drains to find the capacity of the compressors you will need. For example, when using 2 auto drains, 1.5 kW (200 L/min (ANR)) of the compressor capacity is required. ・ Operating pressure: 0.1 MPa or more ・ Operating pressure for AD27-A: 0.1 MPa or more Operating pressure for AD37-A/AD47-A: 0.15 MPa or more 2. When a pressure release 3 port valve is mounted on the inlet side of the regulator or filter regulator, the residual pressure can be released to the inlet side. However, if the set pressure is 0.15 MPa or less, the residual pressure may not be released. When using the pressure release 3 port valve at a set pressure level of 0.15 MPa or less, it is recommended to use a regulator with backflow function. Warning Air Supply 1. Use an air filter with 5 μm or less filtration rating on the inlet side of the valve to avoid any damage to the seat caused by dust when mounting a pressure relief 3 port valve on the inlet side. Caution Mounting/Adjustment 1. When the bowl is installed on the air filter, filter regulator, lubricator, mist separator, or micro mist separator (AC25-A to AC40-A), install them so that the lock button lines up to the groove of the front (or the back) of the body to avoid drop or damage of the bowl. Caution Be sure to read this before handling. Refer to the back cover for Safety Instructions, “Handling Precautions for SMC Products” and the Operation Manual for F.R.L.
