Installation Guidelines
The flow switch can be installed in every position far from elbows or throttlings, with arrow on flow direction. If pipe is vertical, recalibrate range to balance paddle weight. If the device is downwards mounted, take care to slags and apply it in a straight pipe that is far from filters, valves, etc., with length at least 5 times the diameter of pipe upstream and downstream the unit.
The flow switch is factory calibrated at its minimum sensitivity. To increase the set valve, turn the adjustment screw clockwise. The cut-out valve must be ≥ the minimum flow necessary to guarantee the protection of the plant.
