Note 1) Set the inlet pressure to at least 0.05‑MPa higher than the set pressure.
Note 2) Options B, G, H, M are not assembled and are supplied loose at the time of shipment.
Note 3) Set nuts are included with the bracket. (applicable to the AR20(K)-B to AR40(K)-B). 2 mounting screws included for the AR50(K)-B/AR60(K)-B.
Note 4) When the pressure gauge is attached, a 1.0‑MPa specification will be fitted for standard (0.8‑MPa setting) type; 0.4 MPa for the 0.2‑MPa type.
Note 5) When choosing with H (panel mount), the installation space for lead wires will not be secured. In this case, select "wiring top entry" for the electrical entry. (Select "wiring bottom entry" when the semi-standard Y is chosen simultaneously.)
Note 6) Pressure can be set higher than the specification pressure in some cases, but use with the pressure within the specified range.
Note 7) Thread type: NPT is applicable. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan). Round-type pressure gauge (with color zone): cannot be used in combination with M. The digital pressure switch, which has the unit selection function, has a default setting of psi.
Note 8) Options: E1, E2, E3, E4. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan).
Note 9) ○ is for thread type NPT only.
Note 10) △: Combination available for options E1, E2, E3, E4.
