- Uniform Coverage: Delivers highly uniform distribution, reducing dry spots and improving water efficiency.
- Compatibility: Designed to fit all Rain Bird spray heads and shrub adapters.
- Removable Filter Screen: Helps prevent clogging and is easy to clean.
Setup and Installation
Follow these steps to properly install your R-VAN1318 nozzle:
- Turn Off Water Supply: Before beginning, ensure the main water supply to your irrigation system is completely shut off.
- Remove Old Nozzle (if applicable): Unscrew the existing nozzle from the sprinkler head riser.
- Clean Riser and Filter: Inspect the sprinkler riser for any debris. Ensure the R-VAN nozzle's filter screen is clean and properly seated.
- Install New Nozzle: Screw the R-VAN1318 nozzle onto the sprinkler head riser. Hand-tighten only; do not overtighten.
- Check Alignment: Ensure the nozzle is securely seated and aligned correctly on the riser.
- Turn On Water Supply: Slowly turn the water supply back on and check for leaks.
Operation and Adjustment
The R-VAN1318 nozzle allows for easy, tool-free adjustment of both arc and radius.
Adjusting the Arc (Spray Pattern)
- Identify Fixed Left Edge: The nozzle has a fixed left edge. To locate it, rotate the nozzle's top collar clockwise until it stops. This is the fixed left stop.
- Adjust Right Edge: While the water is running, hold the fixed left edge in place. Rotate the top collar counter-clockwise to increase the arc or clockwise to decrease the arc. The arc can be adjusted from 45° to 270°.
- Fine-Tune: Make small adjustments until the desired spray pattern is achieved, ensuring water covers the intended area without overspray.
Adjusting the Radius (Throw Distance)
- Locate Radius Adjustment Ring: The radius adjustment ring is located just below the arc adjustment collar.
- Reduce Radius: To reduce the throw distance, grasp the radius adjustment ring and rotate it clockwise. You can reduce the radius by up to 25%.
- Increase Radius: To increase the throw distance, rotate the radius adjustment ring counter-clockwise.
- Observe Spray: Adjust while the water is running to accurately gauge the throw distance and ensure proper coverage.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your R-VAN nozzles.
- Filter Screen Cleaning: Periodically check and clean the filter screen located at the base of the nozzle. Turn off the water, unscrew the nozzle, remove the screen, rinse it under running water, and reinsert.
- Debris Removal: If the nozzle's spray pattern is obstructed, carefully remove any visible debris from the nozzle opening. Do not use sharp objects that could damage the nozzle.
- Winterization: In freezing climates, ensure your irrigation system is properly winterized according to local guidelines to prevent damage from freezing water. This typically involves draining the system or blowing out the lines with compressed air.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No water or low flow from nozzle | Clogged filter screen; insufficient water pressure; main water supply off. | Clean filter screen; check system water pressure; ensure main water supply is on. |
| Uneven spray pattern | Debris in nozzle opening; incorrect arc adjustment. | Carefully remove debris; readjust the arc as described in the "Operation and Adjustment" section. |
| Water pooling near sprinkler head | Radius set too short; low water pressure. | Increase radius adjustment; check system water pressure. |
| Nozzle not rotating | Debris inside the nozzle mechanism; very low water pressure. | Clean the nozzle thoroughly; ensure adequate water pressure. If problem persists, consider replacing the nozzle. |
