Safety Instructions

• Always wear appropriate personal protective equipment (PPE) when operating the nozzle.
• Ensure all connections are secure before pressurizing the hose.
• Do not direct the water jet at electrical equipment or personnel unless specifically trained and equipped for such operations.
• Maintain a firm grip on the nozzle during operation due to potential recoil force.
• Do not modify the nozzle in any way. Use only genuine Wiltec replacement parts.

Setup and Connection

The Wiltec C2 Fire Hose Nozzle is designed for quick and secure connection to standard Storz C/52 mm (2") couplings.

1. Inspect Connection: Ensure the Storz coupling on the nozzle and the hose are clean and free from debris. Check the rubber gasket for any damage.
2. Connect Nozzle: Align the Storz coupling on the nozzle with the Storz coupling on the fire hose.
3. Secure Connection: Push the couplings together and rotate one of them until the lugs engage securely. A tight seal is crucial for preventing leaks and maintaining pressure.
4. Verify Connection: Gently pull on the nozzle to ensure it is firmly attached to the hose.

Operating Instructions

The Wiltec C2 nozzle offers versatile control over water flow and spray patterns.

Flow Rate Adjustment

This nozzle allows for five distinct flow rate settings, ranging from 150 to 660 liters per minute (l/min). Rotate the flow selector ring to choose the desired output:

• 150 l/min
• 180 l/min
• 300 l/min
• 450 l/min
• 660 l/min

Select the appropriate flow rate based on the application requirements to optimize water usage and effectiveness.

Spray Pattern Adjustment

The nozzle features a continuous spray cone adjustment, allowing for various patterns:

• Full Jet: A concentrated stream for maximum reach and impact.
• Spray Jet: A diffused pattern for wider coverage, cooling, and extinguishing. The fine droplets (approx. 0.3mm) enhance cooling effects.
• Water Curtain: A broad, protective curtain of water, useful for personal protection or creating a barrier.

Rotate the front nozzle head to transition smoothly between these patterns. The wide angle spray (over 120°) provides extensive coverage.

"Flush" Function

The integrated "Flush" function allows for quick internal cleaning to remove dirt particles or foreign objects that may enter the nozzle due to contaminated water. To activate, rotate the designated "Flush" ring or lever (refer to markings on the nozzle) to its open position. This will temporarily increase the flow to clear obstructions. Return the ring/lever to its normal operating position after flushing.

Maintenance

Regular maintenance ensures the longevity and reliable performance of your Wiltec C2 Fire Hose Nozzle.

• After Each Use:
  • Activate the "Flush" function to clear any internal debris.
  • Rinse the exterior of the nozzle with clean water to remove dirt, mud, or chemical residues.
  • Inspect the Storz coupling gasket for wear or damage. Replace if necessary.
• Storage: Store the nozzle in a clean, dry place, away from direct sunlight and extreme temperatures.
• Periodic Inspection: Regularly check all moving parts for smooth operation. Lubricate as needed with a suitable, water-resistant lubricant.
