The HFS-T Tee Type Paddle Flow Switches are Single - Pole, Double - Throw (SPDT) flow switches that are used in liquid lines carrying water ,ethylene glycol,or other liquids not classified as hazardous. They can be wired to energize one device and de-energize another device powered from the same source when liquid flow either exceeds or drops below the set flow rate.
Note: The HFS-T Tee Type Paddle Flow Switches can not be used where the liquid in the pipes will drop below the liquid's freezing point, causing an internal freeze-up.

Mounting:
Flow switch should be mounted in a horizontal pipe line or vertical pipe line.Mount the instrument in a section of pipe where there is a straight run of at least 5 pipe diameter on each side of the flow switch.
To Adjust Setting:
1.Remove switch cover.
2.For higher flow rate, turn flow rate adjusting screw counterclockwise.
3.For lower flow rate, tur flow rate adjusting screw clockwise.
4.Make sure flow switch cover is assembled before leaving.
CAUTION:
Equipment damage hazard.Position Adjusting Screw is not intended to be changed.Adjustment attempts may damage the control or cause loss of calibration,voiding the warranty.
