SPECIFICATIONS:

• Connection Type: 1" Male NPT (National Pipe Taper) threaded
• Flow Rate: 23 GPM (gallons per minute)
• Operating Pressure: 80 PSI
• Coverage Radius: 71 feet
• Nozzle Sizes Included: 1/4" (range nozzle), 7/32" (close-in nozzle)
• Construction Material: Solid Brass body, Stainless Steel drive spring
• Included in Product: One Underhill 1" Part/Full Circle Impact Sprinkler Head (SI100P) with standard solid brass nozzle.

HOW TO USE:

1. Prepare Connection: Ensure your water supply line or portable sprinkler base has a 1" female NPT connection.
2. Thread Sprinkler Head: Carefully thread the 1" Male NPT end of the Underhill SI100P sprinkler head into the corresponding female connection. Hand-tighten first, then use a wrench to secure, being careful not to overtighten.
3. Adjust Spray Pattern (if applicable): For part-circle operation, locate the adjustment collars or tabs on the sprinkler head. Set the desired arc by positioning these stops to define the start and end points of the watering area. For full-circle operation, ensure the stops are disengaged or set for a complete 360-degree rotation.
4. Position Sprinkler: Place the sprinkler in the desired location within the area to be irrigated, ensuring it has clear access to the water source.
5. Activate Water Supply: Slowly turn on the water supply to the sprinkler. Observe the spray pattern to confirm adequate coverage and make minor adjustments to placement if necessary.
6. Monitor Performance: Periodically check the sprinkler's operation to ensure consistent rotation and water distribution.
