The flow switch can be installed in any position away from elbows or throttling points, with arrow aligned to flow direction. For vertical pipe installation, recalibrate range to balance paddle weight. When downward mounting, avoid slag accumulation and install in straight pipe sections at least 5 times the pipe diameter upstream and downstream from filters, valves, and other components.
Note: Factory calibrated at minimum sensitivity. To increase set value, turn adjustment screw clockwise. Cut-out value must be ≥ minimum flow necessary for plant protection.
