PRODUCT OVERVIEW

Direct the water. Control the shut-off.

The Frozenfire Constant Jet Nozzle delivers a straight stream through a 20 mm smooth bore. The catalogue specifies 500 LPM, a typical operating pressure of 7 bar and a 2½″ inlet connection.

A hard anodized aluminium alloy body, ergonomic pistol grip and bale-operated ball valve bring the nozzle controls together. Pressure compensation is described within the designed operating range; confirm that range for the selected supply configuration.

Smooth-bore stream

A 20 mm bore provides a concentrated straight-stream discharge.

500 LPM duty

The catalogue specifies a 500 LPM constant flow configuration.

Manual shut-off

A bale handle operates the ball valve for on/off control.

Connection choice

A 2½″ inlet with instantaneous, BS 336, NH, Storz or BSP options.

INSPECTION & MAINTENANCE

Keep the nozzle
ready for service.

The product catalogue sets out the following inspection and care guidance. Keep the original document with your equipment records.

01Inspection before use

Inspect the body for damage or corrosion, and check the inlet coupling, locking lugs, fasteners and retaining pins.
Check for smooth bale movement and inspect O-rings and seals for wear, cuts or deformation.

02Cleaning and lubrication

Flush thoroughly with clean fresh water after use, particularly after sea water or contaminated-water exposure.
Clean the exterior with a soft cloth; avoid abrasive cleaners, steel brushes and aggressive solvents.
Use silicone-based or manufacturer-approved lubricant sparingly on moving joints and bale pivots. Do not lubricate the discharge or internal flow passages.

03Functional checks

Check for leakage at the inlet and shut-off valve, and verify smooth opening and closing.
Check flow performance at the rated operating pressure and test the nozzle after maintenance before returning it to service.

04Storage and replacement parts

Drain the nozzle and store it in a clean, dry, ventilated location, protected from sunlight, dust and corrosive chemicals.
Keep inlet protective caps fitted and protect the nozzle from impact or heavy loads.
Replace worn seals, gaskets, pins, handles or coupling components with genuine Frozenfire parts.

05Maintenance precautions

Completely depressurise the hose line before inspection or maintenance. Never dismantle a nozzle connected to a pressurised supply.
Do not modify components. Replace damaged parts promptly and have routine maintenance carried out by trained personnel.

Recommended inspection intervals
