Installation Guidelines
Mount the flow switch in ducts or chambers where the air paddle can point horizontally downwards. Provide straight zones of 5 times the duct diameter upstream and downstream from installation to prevent air swirl and paddle instability.
Important Notes
Units are factory calibrated to minimum switch-off values. Adjust the range screw clockwise to increase set values. For air speeds exceeding 5.0 m/sec, cut the paddle on the marked side to prevent fracture, which increases minimum cut-out from 1.0 m/sec to 2.5 m/sec.
