1. Introduction
Thank you for choosing the Aqualine I50A-532 Brass Adjustable Impact Sprinkler. This manual provides essential information for the proper installation, operation, and maintenance of your sprinkler to ensure optimal performance and longevity. Please read these instructions carefully before use.
2. Product Overview
The Aqualine I50A-532 is a durable brass impact sprinkler designed for efficient and adjustable watering. It features a 1/2" MPT inlet connection and is constructed with high-quality brass, white bronze, and stainless steel components for reliability.

Key Components:
- Brass Body: Provides durability and corrosion resistance.
- White Bronze Anti-Backsplash Arm: Ensures consistent rotation and prevents water from spraying backward.
- Stainless Steel Deflector Pin: Used for adjusting the spray pattern.
- Trip Sets: Mechanisms for setting the arc of rotation.
- Collar: Secures components and aids in adjustment.
- 1/2" MPT Inlet Connection: Standard male pipe thread for easy connection to irrigation systems.
3. Setup and Installation
- Prepare Connection: Ensure your water supply line or riser has a compatible 1/2" FPT (Female Pipe Thread) connection.
- Apply Thread Sealant: Wrap plumber's tape (PTFE tape) clockwise around the 1/2" MPT inlet threads of the sprinkler to ensure a watertight seal.
- Attach Sprinkler: Carefully thread the sprinkler onto the prepared connection. Hand-tighten first, then use a wrench to tighten an additional 1/2 to 1 full turn. Avoid over-tightening, which can damage threads.
- Positioning: Place the sprinkler in the desired location, ensuring it is upright and stable for optimal water distribution.
4. Operating Instructions
The Aqualine I50A-532 sprinkler is designed for adjustable operation, allowing for both full-circle and partial-circle (arc) watering patterns.
Adjusting the Watering Arc:
- Full Circle Operation: To achieve a continuous 360-degree watering pattern, ensure the trip sets (arc adjustment clips) are disengaged or set to their widest position, allowing the sprinkler head to rotate freely.
- Partial Circle (Arc) Operation: The sprinkler can be adjusted to water an arc between 20 and 340 degrees. Locate the trip sets on the sprinkler head. By moving these clips, you can define the start and end points of the desired watering arc. The sprinkler arm will impact these clips, causing the head to reverse direction.
Water Pressure and Flow:
- Operating Pressure Range: The sprinkler operates optimally within a pressure range of 25 to 50 PSI (Pounds per Square Inch).
- Flow Rate: The flow rate varies between 2.6 and 5.0 GPM (Gallons Per Minute), depending on the installed nozzle size. This model is equipped with a 5/32" nozzle.
- Trajectory Angle: The water stream is projected at a 25-degree trajectory angle, reaching a highest point of approximately 5 feet above the nozzle level.
5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your Aqualine impact sprinkler.
- Cleaning Nozzle: Periodically check the nozzle for any debris or mineral buildup that might obstruct the water flow. Use a small, non-metallic tool to gently clear any blockages.
- Lubrication: The moving parts are designed for minimal maintenance. However, if rotation becomes stiff, a small amount of silicone-based lubricant can be applied to the pivot points, avoiding the nozzle opening.
- Winterization: In freezing climates, disconnect the sprinkler from the water source and drain all water to prevent damage from ice expansion. Store in a dry, protected area.
- Inspection: Regularly inspect the sprinkler for any signs of wear, damage, or leaks. Replace worn components as necessary.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sprinkler not rotating | Low water pressure; Debris in nozzle or mechanism; Trip sets engaged for arc. | Check water pressure; Clean nozzle and mechanism; Ensure trip sets are disengaged for full circle. |
| Uneven water distribution | Clogged nozzle; Incorrect deflector pin setting; Low water pressure. | Clean nozzle; Adjust deflector pin; Verify adequate water pressure. |
| Water leaking from connection | Loose connection; Damaged threads; Insufficient thread sealant. | Tighten connection; Reapply thread sealant; Inspect threads for damage. |
