  • Page 3: Safety Instructions

    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.
  • Page 4 Safety Instructions Caution 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.
  • Page 5 Precautions for Design Warning (1) Consult SMC if no leakage is allowed due to the environment, or if the operating fluid is not air. (2) Polycarbonate resin is used for the external parts including the bowl. Organic solvents including thinner, acetone, alcohol and ethylene chloride; chemicals including sulphuric acid, nitric acid and hydrochloric acid;...
  • Page 6 (3) Avoid the application where charge and discharge of pressure to/from a standard bowl is switched frequently. This may damage the bowl. A metal bowl is recommended in these cases. (4) Shield from ultra violet light and radiation with protective cover. (5) A safety device needs to be installed if output pressure is exceeding the set pressure, otherwise this can cause breakage of outlet device and equipment or lead to malfunction.
  • Page 7 Adjustment Warning (1) Adjust the set pressure ensuring correct inlet and outlet pressures. Turning the knob excessively can cause damage to the internal parts. (2) Do not use tools on the pressure regulator knob as this may cause damage. It must be operated manually.
  • Page 8 (7) The piping for drain from auto drain should be connected under the following requirements to avoid operating failure. Tubing for AD27-D: I.D. ø2.5 (ø3/32") or larger, Length 5 m (200 inch) or shorter Tubing for AD37, 47(N)-D: I.D. ø4 (ø3/16") or larger, Length 5 m (200 inch) or shorter Tubing for AD38, 48(N)-D: I.D.
