Page 17: System Considerations
SYSTEM CONSIDERATIONS Working With WFS 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 18 Some water sources may have varying pressure Additionally, excess air in irrigation piping causes depending upon the demand for water upstream the WFS 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 19 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.
