2. Setup Instructions

1. Preparation: Ensure the water source is turned off and depressurized before beginning installation.
2. Connection: Thread the Dixon Valve HFN100-FM nozzle onto a compatible hose or pipe fitting.
3. Tightening: Hand-tighten the nozzle initially, then use an appropriate wrench to secure it firmly. Avoid overtightening, which can damage threads or seals.
4. Verification: Once connected, ensure all fittings are secure and there are no visible gaps.
5. Water Supply: Slowly turn on the water supply and check for any leaks at the connection point. If leaks occur, turn off the water, re-tighten the connection, or inspect the threads and seals for damage.

3. Operating Instructions

The Dixon Valve HFN100-FM nozzle features an adjustable head to control the water spray pattern.

• Adjusting Spray Pattern: Rotate the nozzle head to cycle through the available spray patterns.
• Available Patterns: The nozzle can deliver a straight stream, 30-degree fog, 60-degree fog, and 90-degree fog.
• Shut-Off Function: Continue rotating the nozzle head to reach the 'shut-off' position, which will stop the water flow.
• Safety: Always maintain a firm grip on the nozzle during operation, especially when using high-pressure settings or straight stream patterns.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Dixon Valve HFN100-FM nozzle.

• Flushing: After each use, flush the nozzle with clean water to remove any debris, sediment, or chemical residues.
• Inspection: Regularly inspect the nozzle for signs of wear, damage, or blockages in the spray orifices.
• Cleaning: If blockages or mineral deposits are present, gently clean them using a soft brush or cloth. Avoid using abrasive tools or harsh chemicals that could damage the brass finish or internal components.
• Storage: Store the nozzle in a clean, dry environment away from extreme temperatures and direct sunlight when not in use.

5. Troubleshooting

Refer to the following common issues and solutions:

• Reduced Water Flow or Inconsistent Spray Pattern:
  • Check for blockages in the nozzle opening or internal components.
  • Ensure the water supply is adequate and the hose is not kinked or obstructed.
• Leaks at the Connection Point:
  • Ensure the nozzle is securely tightened to the hose or pipe fitting.
  • Inspect the condition of any washers or O-rings at the connection point and replace if they are worn or damaged.
  • Check for damaged threads on both the nozzle and the hose/pipe fitting.
