From the Project Irrigation Manager, select the radial button Heads. The drop down box will list the components for the Head category. Select the type of spray head desired, either Turf Spray or Shrub Spray. In this example select Turf Spray.
Note that you may have up to two Turf Sprays in a project, and up to four Shrub Sprays. The toolbar for selecting them will be in the same order they appear in the Irrigation Manager.
Select Add and a list of manufacturers that have data in the Land F/X database for that component will be listed.
In this example select Rain Bird to view the Series dialog box for this component.
After selecting a manufacturer, all of the equipment options for that manufacturer will be displayed. In this example Rain Bird offers turf spray bodies with 2” popup to 6” popup, and body combination choices of: plain, a pressure regulator (PRS), a check valve (SAM), or a check valve and pressure regulator (SAM-PRS)
For this example select the 1804 (4” popup) SAM-PRS (check valve and pressure regulator). Click Add to Project and you will be able to select the Design Pressure and Radius Reduction percent for that head in the Pressure Options dialog box.
The Design Pressures indicated are those listed by the manufacturer in their documentation. The spray heads Design Pressure defaults to the pressure which provides the rated radius coverage for that head type. In this case 30 psi is the default Design Pressure. Default Pressures are only provided for spray heads. These default pressures result in the optimum performance for the nozzle, so that a 12 ft. radius nozzle will provide 12 ft. radius of coverage (according to the manufacturer) with the default pressure. If a different pressure is desired, simply click that radial button.
Selecting a lower pressure will result in the corresponding manufacturer’s listed radius for that pressure when the head is placed into the drawing. Therefore a 15 Series Rain Bird nozzle with a Design Pressure of 30 psi will be drawn at a 15 ft radius when placed on the drawing, if 25 psi is selected for the Design Pressure the radius drawn will be 14 ft, and if 20 psi is selected for the Design Pressure the radius drawn will be 12 ft, all as indicated on the manufacturer’s performance data.
The Radius Reduction Percent is a sliding bar that effects the radius that will be drawn in 5% intervals. The irrigation Designer may want a certain Design Pressure, say 30 psi, and may also want to represent a smaller radius for a head than listed by the manufacturer performance data, for instance if there are heavy winds in the area, or if the Designer wishes to be more conservative in the radius represented by the head. Many Designers prefer that the radius drawn on the Irrigation Plan be an 85% to 90% Radius Reduction from that listed by the manufacturer for a given Design Pressure. Note that although it operates in 5% increments, the system will round the result down to the nearest whole number. Thus, a 5' spray head will be represented with a 4' radius with any radius reduction from 80-95%.
After selecting a Design Pressure all of the nozzle combinations for this body type will be added to the project and available for use in an Irrigation Plan.
If at any time during the selection process you wish to view the manufacturer’s performance data, select the View Data button, which are available within the Irrigation Manager, Equipment Options, and Pressure Options dialog boxes.
Viewing the data on command allows the irrigation Designer to quickly access the manufacturer’s performance requirements to evaluate the suitability of the equipment for the required irrigation tasks
From the Project Irrigation Manager, select the radial button Heads. The drop down box will list the components for the Head category. Select the type of rotor head desired, either Turf Rotor or Shrub Rotor. In this example select Turf Rotor.
Select Add and a list of manufacturers that have data in the Land F/X database for that component will be listed.
In this example select Hunter to view the Series Options dialog box for this component. If a manufacturer has more than one series option for a type of equipment, the Series Options dialog box will appear allowing the Designer to determine what series of head to use.
Select a Series of Turf Rotor from the Hunter product line. In this example select the I-40 Series. The available options for the I-40 will appear. In this case two options are available, the I‑40 ADS, 36S for adjustable and full circle with check valve and stainless steel riser, or the I‑40 ARS, 3RS for the same as above fro reclaimed water.
Select the Series Option and click Add to Project. You will then be directed to select a symbol to represent this head. You can add to this symbol library, or alter the existing symbols, see Adding User Defined Irrigation Symbols to Land F/X.
Select a desired symbol and the Design Pressure dialog box will appear.
Select an appropriate Design Pressure for this head. The Designer may have to click on the View Data button to view the manufacturer’s performance data, and to consider what static pressure is available for the project, to make a decision on which Design Pressure to use.
The Radius Reduction Percent is a sliding bar that effects the radius that will be drawn in 5% intervals, rounded down to the nearest whole foot, the same as mentioned for spray heads above.
When you select a Design Pressure, the corresponding manufacturer’s listed radius for that pressure, along with any radius reduction, will be drawn when the head is placed into the drawing.
If at any time during the selection process you wish to view the manufacturer’s performance data, select the View Data button, which are available within the Irrigation Manager, Equipment Options, and Pressure Options dialog boxes.
