Tees, ells, Observe the following general rules when choosing and other fittings cause turbulence which the sensor location and preparing to install: affects accuracy.
- Page 10 The FCT tee fitting is designed for glue (“slip”) • Example: FCT-200 is installed in a 2"/50 mm diameter pipe. The tee should have 20"/50 connection. Use approved PVC solvent-welding cm of straight pipe upstream, and 10"/25 cm glue to install either threaded fittings, or directly straight pipe downstream.

SYSTEm CONSIDERATIONS Working With Flow-Sync Hunter flow-capable controllers are designed active stations, to see if there is an unacceptable to measure and record actual flow, shut off difference, indicating a leak or break. irrigation when a high flow condition occurs, and Consult the controller documentation closely for identify which stations caused the condition. - Page 19 Mainline Pressure Fluctuation Some water sources may have varying pressure Additionally, excess air in irrigation piping causes depending upon the demand for water upstream the Flow-Sync impeller to spin freely during of the point of connection. During times of heavy station startup, which may cause temporarily demand, system pressure through the mainline high readings.
- Page 20 Proper System Maintenance and Operation It is important that your irrigation system be maintained and is functioning properly for optimum performance. Check your irrigation system for any broken components or leaks also, making sure that all sprinklers are operating within the pressure ranges recommended by the manufacturer.

TROUBLE-SHOOTING GUIDE Problem Cause Solution Flow-Sync not reading Water shut off Verify that no isolation valves are closed, and that the water source is on. Controller not configured Check controller flow sensor setup. Enter sensor size (and location, for sensor decoders) and other sensor information as required. - Page 23 Problem Cause Solution Flow-Sync not reading correctly Controller configured incorrectly Set correct flow sensor size and type at controller. Turbulent flow at sensor Insure that straight pipe is on either side of flow meter. Frequent false alarms Station settings too sensitive Increase overflow percentage (and underflow if available).
