Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations.

Safety Instructions Caution 1.The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.
The product has the following features. (1) A sensitivity of 0.2%F.S. at max is achieved by the nozzle and flapper design. (IR1000: F.S. 0.2MPa, IR1010: F.S. 0.4MPa, IR1020: F.S. 0.8MPa) Note) “F.S.” is the abbreviation of full span.

(Note1) Minimum supply pressure: At a downstream side flow rate of zero. Be sure to keep the minimum supply pressure. (setting pressure+0.05MPa) (Note2) Setting pressure: At a downstream side flow rate of zero. (Note3) Setting sensitivity: This is the minimum pressure range that the downstream pressure is adjustable by conducting fine adjustment of the setting knob on the downstream side of the precision regulator.
2. Construction and operation principle When the setting knob is turned, the nozzle is closed by the flapper, allowing the supply air that flows in from the upstream side to pass through the fixed orifice. It then acts on diaphragm(C) as nozzle back pressure, the main valve is pushed down by the generated force and the supply pressure flows out to the downstream side.
Note2) Note3) G: Pressure gauge Thread type when Rc and G. Thread type when NPT. Set pressure IR1000 : G33-2-01 G33-P2-N01-X30 Thread type 0: 0.005~0.2MPa IR1010 : G33-4-01 G33-P4-N01-X30 NIL:Rc 1: 0.01~0.4MPa IR1020 : G33-10-01 G33-P10-N01-X30 N:NPT 2: 0.01~0.8MPa (Note 1) In the standard mounting position, the product name plate is attached to the front and the bracket is mounted to the back when viewed with the SUP side on the left and OUT side on the right.
5. Precautions for handling Warning Fluid (1) The operating fluids must be compressed air. Contact SMC when using the product with other fluids. (2) Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or corrosive gases, etc., as this can cause damage or malfunction. (3) If condensate in the drain bowl is not emptied on a regular basis (air filter and mist separator), the bowl will overflow and this may cause the malfunction of pneumatic equipment.

Warning Maintenance (1) When the Spring Holder is to be removed (see construction on page 6), reduce the set pressure to 0 and shut off the supply pressure completely beforehand. (2) If a pressure gauge is to be added, reduce the set pressure to 0 before removing the plug. (3) Rubber parts such as diaphragm, o-rings and seals are consumption, and should be replaced every three years.

(2) Do not apply torsion or bending moment other than the weight of the product itself. The external piping should be supported separately because it may cause breakage. (3) Non-flexible piping such as steel piping will be subject to excessive moment load and vibration from the piping side, so use a flexible tube for intermediate connection.

Warning Operation (1) Do not use a precision regulator outside the range of its specifications as this can cause failure.(Refer to the specifications.) (2) Screw a panel nut with the recommended proper torque 12.5N m when mounting onto a panel. Looseness or faulty sealing will occur if tightening torque is insufficient, while thread damage will result if the torque is excessive.
6. Warranty Period: The warranty period of the product is 1 year in service or 1.5 years after the product is delivered, whichever is first. Scope: For any failure or damage reported within the warranty period which is clearly our responsibility, a replacement product or necessary parts will be provided.
7. Troubleshooting Trouble Possible cause Countermeasures Reset the pressure. Fluctuation of flow rate at the Return the flow rate at the downstream side downstream side to the initial rate. Clogging of fixed orifice due to moisture, Install a filter and mist separator and condensation or foreign matter use clean air.
