Caution indicates a hazard with a low level of risk which, if not avoided, could result in minor or moderate injury. Caution: Warning indicates a hazard with a medium level of risk which, if not avoided, could result in death or serious injury. Warning: Danger : Danger indicates a hazard with a high level of risk which, if not avoided, will result in death or serious injury.

When replacing an old AR series regulator with the following conditions (A to E), select a regulator from the AR20-B to AR60-B series.
(A) The set pressure is 0.7 to 0.85 MPa. (B) A square embedded type pressure gauge or digital pressure gauge is required. (C) The same dimensions for panel mounting are required. (D) A regulator with a backflow function is required.
