Setup and Installation
Proper installation is crucial for optimal performance and longevity of your Hunter I-90ADV sprinkler. It is recommended to consult a professional for complex irrigation system designs.
Pre-Installation Checks:
- Ensure adequate water pressure and flow rate for the sprinkler's specifications.
- Verify the correct piping and fittings are available.
- Plan the sprinkler layout to ensure even coverage.
Installation Steps:
- Excavate Trench: Dig a trench to the appropriate depth for the sprinkler body, ensuring it is level with the finished grade.
- Connect to Lateral Line: Connect the sprinkler to the irrigation lateral line using appropriate fittings. Ensure all connections are watertight.
- Position Sprinkler: Place the sprinkler body in the trench, ensuring the top of the sprinkler is flush with the ground surface when installed.
- Backfill Trench: Carefully backfill the trench, compacting the soil around the sprinkler body to secure it in place.
- Nozzle Installation (if not pre-installed): Remove the cap and insert the desired color-coded nozzle. The I-90ADV allows for field-changed nozzles to match specific needs.
Operating Instructions
The I-90ADV features an adjustable arc and can be fine-tuned for precise watering.
Arc Adjustment:
- The I-90ADV is an adjustable arc model. To adjust the arc, use the Hunter wrench or a flat-blade screwdriver to turn the adjustment screw located on the top of the sprinkler.
- Turn clockwise to decrease the arc, and counter-clockwise to increase it.
- Ensure the sprinkler is operating during adjustment to observe the spray pattern.
Radius Adjustment:
- The spray radius can be adjusted by turning the radius reduction screw on the nozzle.
- Turning the screw clockwise will decrease the throw distance.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your sprinkler.
Filter Screen and Check Valve Access:
- The I-90ADV features a "jar-top" body cap, allowing quick access to the internal components.
- To access, unscrew the top cap counter-clockwise.
- Carefully remove the filter screen and rinse it under running water to remove any debris.
- Inspect the check valve for any obstructions or damage.
- Reassemble by screwing the cap back on, ensuring a tight seal.
Winterization:
- In freezing climates, it is essential to winterize your irrigation system to prevent damage.
- Drain all water from the system, or use an air compressor to blow out the lines. Consult a professional for proper winterization procedures.
