- Unscrew Top: Simply unscrew the top of the existing spray head.
- Remove Assembly: Pull out the top and internal assembly.
- Insert Pro-S Assembly: Replace it with the top and assembly from a K-Rain Pro-S spray head. No digging required.

Operating Instructions
Adjusting Spray Arc and Distance:
The Pro-S spray heads with adjustable nozzles allow for precise control over the spray pattern and distance. This ensures water is delivered only where needed, minimizing waste.
- Adjusting Arc (Left Start): While the sprinkler is operating, grasp the lower part of the riser and twist it to set the left start position of the spray arc. It will click into place.
- Adjusting Arc (Right Stop): Grasp the very top of the spray head (the nozzle) and twist it to adjust the right stop position of the spray arc.
- Adjusting Distance (Radius): To reduce the spray distance, use a flat-head screwdriver to turn the silver screw located in the very middle of the nozzle counter-clockwise. Turning it clockwise will increase the distance. Hold the riser steady with one hand while adjusting with the screwdriver.

Maintenance
Regular maintenance ensures the longevity and efficiency of your K-Rain Pro-S spray heads.
- Cleaning: Periodically inspect nozzles for clogs from debris. Clean as needed to maintain optimal spray patterns.
- Wiper Seal Inspection: The co-molded wiper seal is designed for durability, but inspect it annually for any signs of wear or damage that could affect retraction or lead to leaks.
- Winterization: In colder climates, ensure proper winterization procedures are followed to prevent freeze damage. Consult local irrigation guidelines for specific steps.
Optional Features for Enhanced Performance:
- Stop Flow: An optional feature that automatically stops water flow in case of nozzle damage or removal, preventing water waste.
- In-Stem Pressure Regulation: Available for 4", 6", or 12" models (in both 30 and 40 PSI), this feature prevents misting and saves water by maintaining consistent pressure.
- Nozzle Guard: Adds a protective lip around the nozzle to prevent damage from foot traffic and lawn equipment.
- Pre-installed Check Valve: Prevents low head drainage, saving water and reducing erosion. Can also be purchased separately and installed in the field. Check valves hold up to ten feet of head pressure.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No water or low flow: | Clogged nozzle or filter, insufficient water pressure. | Clean the nozzle and filter. Check system pressure. |
| Head not retracting fully: | Debris around the riser, worn wiper seal, weak spring. | Clear debris. Inspect and replace wiper seal or spring if necessary. |
| Uneven spray pattern or misting: | Incorrect pressure, damaged nozzle, clogged nozzle. | Verify system pressure is within optimal range (30 PSI for this model). Clean or replace nozzle. |
| Leaks at the base of the head: | Loose connection, damaged body, worn seal. | Tighten connections. Inspect for cracks or damage; replace head if necessary. |
