！ Precautions for design WARNING ① External parts including the bonnet, handle, cover (Material: polyacetal) are made of resin. ② ③ ④ ！ Organic solvents including synthetic fluid, chemicals including acetone, alcohol, ethylene chloride, sulphuric acid, nitrate, hydrochrolic acid, cutting oil, kerosene, gasoline, lock material of screw are harmful. Do not use the regulator where containing those. Consult SMC if no leakage is allowed due to the environment, or operating fluid is not air.

・Push the pressure regulator handle to lock. When the handle is not easily locked, turn it left ③ ④ ⑤ ⑥ ！ and right a little and then push it. (When the handle is locked, the "orange mark", i.e., the will disappear.) For the regulator with the pressure gauge, do not apply pressure exceeding the maximum scale of the pressure gauge in order to protect the gauge. Adjust pressure incrementally. Pressure may become lower than set pressure if adjusted by decreasing the value.

2. APPLICATION This product aims at controlling the pressure of air lines. Built in counterflow function allows outlet pressure to be released to inlet side when inlet pressure becomes lower than outlet pressure to specified extent. 3.

7. REPLACEMENT PROCEDURE ！Before WARNING replacement, ensure that the regulator is not pressurized. Rotate the pressure adjusting handle to zero. Replace refering to “8．DISASSEMBLY DRAWING” (P13 to P14). After replacement, ensure that specified function is satisfied and external leakage is not found before starting operation. 1) Diaphragm assembly Procedure 1) Remove the bonnet. Rotate the set screw counterclockwise with cross pointed driver to remove the bonnet from the body.

3) Bracket assembly, panel mount Applicable model AR20K-B AR25K-B AR30K-B AR40K-B Procedure Process Assembly 1) Mount the parts to the bracket (panel). Mate the bracket (panel) concave and the bonnet convex to mount the bracket. 2) Settle the bracket (panel) with set nut. Rotate the set nut clockwise with a hook spanner to settle the parts to the bracket (panel). See check item for tightening torque. Set nut knurling surface shall face the bracket.

6) Pressure gauge adaptor assembly, Plug assembly Applicable model Process Disassembly Procedure 1) Remove the plug. Insert the hexagon spanner to hexagon hole of hexagon plug. Rotate the plug counterclockwise to remove the plug. 2) Remove the pressure gauge adaptor. Rotate two set screws counterclockwise with cross pointed driver to remove the pressure gauge and AR20K-B two set screws. AR25K-B Assembly 3) Confirm pressure gauge adaptor has "O" ring. If AR30K-B not, mount "O" ring.
