If there is a possibility that the atmospheric vent port of the switch will be exposed to water or dust, insert a tube into the
atmospheric vent port and route the other end of the tube to a safe place away from water or dust.
∗ For tubing, please use the SMC TU0425 (polyurethane, O.D. Ø 4, I.D. Ø 2.5) for the pressure switch.
∗ If it is expected that the pressure, such as water hammer or surge pressure, will fluctuate rapidly, refer to the
precautions in the Operation Manual on the SMC website (http://www.smc.eu).
