2. Setup and Installation
Proper installation is crucial for the optimal performance of your Hunter I-Beam SS Pop-Up Sprinkler. Ensure all connections are secure and the sprinkler is positioned correctly for desired coverage.
2.1 Pre-Installation Checks
- Verify that your water pressure is within the recommended operating range of 2.5 to 7 bar (250 to 700 Kpa).
- Ensure you have the necessary tools, including a shovel, pipe cutters, PVC cement/primer (if applicable), and a sprinkler adjustment tool.
2.2 Installation Steps
- Digging the Trench: Dig a trench from your main water line to the desired sprinkler location. The trench should be deep enough to allow the top of the sprinkler to be flush with the ground when installed.
- Connecting to Water Line: Connect the sprinkler to your irrigation piping. The sprinkler features a BSP inlet. Ensure a watertight seal.
- Positioning the Sprinkler: Place the sprinkler in the trench. The top of the sprinkler should be level with the ground surface to prevent tripping hazards and ensure proper pop-up and retraction.
- Backfilling: Carefully backfill the trench, ensuring no debris enters the sprinkler head.
