687F.R. Unit Precautions 2Be sure to read before handling.MountingCaution1. To avoid reversed connections of the air inlet/outlet, makeconnections after confirming the "IN/OUT" mark or arrows thatindicate the direction of air flow. Reversed connections cancause malfunction.2. Components with a bowl, e.g., air filter, filter regulator must beinstalled vertically with the bowl downward to avoid faulty draindischarge and dripping.3. Ensure sufficient top, bottom, and front clearance formaintenance and operation of each component. Refer to thedimension pages for the minimum clearance for eachcomponent.4. Regulator and filter regulatorsBe sure to unlock the knob before adjusting the pressure andto lock it after the pressure is set.5. Regarding drain piping1. 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 todischarge air and drainage.2. 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 casedamage.Air supplyCaution1. When a lot of draining is expectedInstall air dryer and water separator before the air filter or filterregulator.AdjustmentWarning1. Regulator and filter regulator1. Set the regulator while verifying the displayed values of theinlet and outlet pressure gauges. Turning the knobexcessively can cause damage to the internal parts.2. Do not use a tool on the pressure regulator knob as this cancause damage. It must be operated manually.Caution1. Regulator and filter regulator1. Be sure to check the inlet pressure before setting the outletpressure.2. For this product with a 0.02 to 0.2 MPa setting, the optionalpressure gauge should be used with a maximum pressureof 0.2 MPa. Do not apply pressure exceeding 0.2 MPa. Itcan damage the pressure gauge.3. To set the pressure using the knob, turn the knob in thedirection that increases pressure and lock the knob after thepressure is set. If this is done in the direction that decreasespressure, the pressure may drop from the original setpressure. Turning the knob clockwise increases the outletpressure, and turning it counterclockwise reduces thepressure.PipingWarning1. To screw piping materials into components, tighten with arecommended tightening torque while holding the femalethread side. If the minimum tightening torque is not observed,this can cause a looseness and seal failure. On the otherhand, excess tightening torque can cause damage to thethreads. Furthermore, tightening without holding the femalethread side can cause damage due to the excess force that isapplied directly to the piping bracket.Recommended tightening torqueConnectionthreadTorque1/87 to 91/412 to 143/822 to 241/228 to 303/428 to 30Unit: N·m136 to 38Front matter 2
