Electrical Wiring Diagram
Installation Guidelines
The flow switch can be installed in every position far from elbows or throttlings, with arrow indicating flow direction. For vertical pipe installation, recalibrate range to balance paddle weight. When downward mounted, install away from filters and valves in a straight pipe section with length at least 5 times the pipe diameter upstream and downstream.
Note: The flow switch is factory calibrated at minimum sensitivity. To increase the set valve, turn the adjustment screw clockwise. The cut-out valve must be ≥ the minimum flow necessary to guarantee plant protection.
