3. Setup and Installation

1. Preparation: Ensure the irrigation system is turned off and depressurized before beginning installation.
2. Remove Old Nozzle (if applicable): Carefully unscrew the existing sprinkler nozzle from the riser.
3. Clean Riser: Inspect the sprinkler riser for any debris or dirt. Clean thoroughly to ensure a proper seal.
4. Install New Nozzle: Screw the Toro Precision Spray 10-H Nozzle onto the sprinkler riser by hand. Do not overtighten, as this can damage the nozzle or riser threads. Tighten until snug.
5. Adjust Spray Pattern: Once installed, turn on the irrigation system briefly to check the spray pattern. The 10-H nozzle typically provides a half-circle (180-degree) spray pattern. Adjust the arc and radius as needed by rotating the nozzle collar or top, if adjustable. Refer to your sprinkler body's instructions for specific adjustment methods.
6. Check for Leaks: Observe for any leaks around the nozzle connection. If leaks occur, turn off the system, unscrew the nozzle, re-clean threads, and re-install, ensuring a snug fit.

4. Operating Instructions

The Toro Precision Spray 10-H Nozzle operates automatically as part of your irrigation system. Once installed and adjusted, it will deliver water according to your system's programmed schedule.

• Watering Schedule: Set your irrigation controller to a schedule appropriate for your landscape's needs, considering soil type, plant requirements, and local climate.
• Observation: Periodically observe the nozzle during operation to ensure the spray pattern remains consistent and there are no obstructions.

5. Maintenance

Regular maintenance helps ensure the longevity and efficiency of your sprinkler nozzle.

• Screen Cleaning: The integrated screen can accumulate debris over time. If you notice reduced flow or an irregular spray pattern, turn off the system, unscrew the nozzle, and carefully remove and clean the screen under running water. Reinstall the screen and nozzle.
• Winterization: In regions subject to freezing temperatures, ensure your irrigation system, including nozzles, is properly winterized according to your system manufacturer's guidelines to prevent freeze damage.
