The following is intended to provide the basic instructions for operating an Assault nozzle.
PRODUCT WARNINGS
•
Maximum hydrostatic pressure 580 psi/40 bar. Maximum operating pressure 230 psi/16 bar.
•
Not for use on electrical fires.
•
At pressures below that indicated on the label, the nozzle will have reduced flow and reach. Be sure you have enough flow and pressure for the
situation (See ISFTA and NFPA manuals for guidelines).
•
Open and close shut-off slowly. Rapid opening will produce a sudden thrust. Rapid opening or closing can cause water hammer.
•
If any tags or bands on the nozzle are worn or damaged and cannot be easily read, they should be replaced.
GENERAL INSTRUCTIONS
•
Not recommended for use with salt water.
•
After use with foam, flush with fresh water.
•
Have enough firefighters on the line to safely control the reaction force created by the stream.
•
Assault nozzles are labeled for the flow and pressure at which they are set.
•
Charge all lines slowly to facilitate a controlled water pressure build-up during start-up.
•
For firefighters use ONLY.
•
For use with water or standard fire fighting foams ONLY.
•
Ensure your Assault is properly matched to your eductor.
•
Do not use your Assault to throttle flow with an eductor in the line. This can cause the eductor to shut down.
•
Do not use Assault nozzles in portable hose holders.
•
Ensure the Assault is aimed in a direction that is safe, prior to operating.
•
Do not use the Assault as a forcible entry tool.
•
Ensure that the thread on the nozzle swivel is matched to the thread on the hose connection.
•
Do not overtighten the nozzle onto the hose connection.
•
The nozzle is configured for optimum performance. Do not alter in any manner.
•
Do not expose pistol grip or shutoff handle to Trichlorethylene or Trichlorethane.
OPERATING GUIDELINES
SHUTOFF
•
Open and close the Shutoff slowly.
To open: Pull the handle toward the inlet.
To close: Push the handle toward the outlet.
NOZZLE
•
To change the spray pattern rotate the pattern sleeve/bumper. Rotate it clockwise for straight stream (designated by
a I) and counterclockwise for wide fog (designated by a V).
•
The flow setting for an Assault can be changed by purchasing a flow kit.
•
To determine the required engine pressures to achieve the flow setting, use the following formula: Engine pressure (EP) = Friction loss (FL) +
Nozzle pressure (NP) + pressure loss or gain due to elevation (1/2 psi per foot of height difference).
•
To flush the nozzle, rotate the pattern sleeve/bumper counterclockwise to the FLUSH setting. Rotate slowly back to
the required setting when obstruction is flushed.
MAINTENANCE
•
Your nozzle should be inspected prior and after each use, to ensure it is in good operating condition.
