Atmospheric vent port
•Connect tubing (sold separately) to the atmospheric
vent port if there is a possibility that the port could be
blocked by water or dust.
•Recommended tube is TU0425 (material: polyurethane,
O.D. ø4, I.D. ø2.5) made by SMC.
•The other end of the air tubing should be routed to a
safe place to prevent it from being exposed to water
or dust.
•Ensure the tubing has no sharp bends.
