491Air Filter, Regulator/Common PrecautionsqBe sure to read before handling. Refer to pages 7 to 16 of Front matter for safety instructionsand common precautions for clean series. Refer to the main text for precautions for each series.WarningqStandard resin bowl of air filter and filter regulator.Because the product uses polycarbonate as the material, itcannot be used in an atmosphere with synthetic oil, organicsolvents, chemicals, cutting lubricants or thread lock solutions,etc. or in an environment where such liquids may adhere to theproduct.wRegulator and filter regulatorBe sure to provide a safety mechanism if an output pressureexceeding the set pressure value of the regulator or filterregulator is expected to cause damage or malfunction.CautionPrecautions on DesignqAir filter and filter regulatorSelect an optimum model according to the required cleanlinessWarningSelectionqThe residual secondary pressure cannot be releasedwith a regulator after the primary pressure isreleased.Consult SMC to release the residual pressure.wIf a regulator or filter regulator is used in asecondary sealed circuit or in a balanced circuit:Consult SMC because the product cannot be used in somecases.eSet the secondary pressure of regulator within 85%of the supply pressure.A large pressure drop may result.CautionCautionMountingqTo set a right pressureq Pressure setting of the regulator or filter regulator should beachieved by increasing the pressure. Lock the handle afterhaving achieved the set pressure.w Before connecting, confirm the "" symbol indicating an inletof air. A reverse connection may result in malfunction.e Mount the case of the air filter and filter regulator in thedownward direction. It can cause malfunction of the drainexhaust.r Set the regulator and filter regulator while confirming thepressure indication on the primary and secondary pressuregauges. If the handle is rotated more than necessary, it maydamage the internal parts.wRegarding drain pipingq The drain guide case of a filter or filter regulator is notprovided with a valve function to exhaust drainage. Installvalves onto the drain guide before supplying air to dischargeair and drainage.w When piping the drain guide case of the filter or filterregulator, first secure the drain guide with a wrench.Failure to secure the drain guide may result in case damage.Air SupplyqWhen a lot of draining is expectedqInstall air dryer and water separator before the air filter orfilter regulator.472
