Maintenance Instructions - Akron Brass PROVENGER 1602 Instrucciones De Funcionamiento Y Mantenimiento

• For firefighter use only.
• Do not over tighten the nozzle onto the hose connection.
• Do not use the nozzle as a forcible entry tool. Doing so may damage it or make it inoperable.
• If any tags or bands on the nozzle are worn or damaged and cannot be easily read, they should be replaced.
• For use with fresh water or standard firefighting foams only. Not recommended for use with salt water.
After use with foam or salt water, flush with fresh water.
• When using with an eductor, make sure the nozzle is properly matched to the eductor. If they are not,
the nozzle flow, pressure, and reach may be reduced or the eductor may shutdown. Do not throttle your
nozzle with an eductor in the line. This can cause the eductor to shut down.
• The nozzle is configured for optimum performance. Do not alter in any manner.
• Do not expose the pistol grip or shutoff handle to Trichloroethylene or Trichlorethane. These chemicals
can weaken the parts and make the nozzle inoperable over time.
• Drain the nozzle after use to prevent freeze damage.
Operating Instructions
BALL SHUTOFF
• Open and close slowly.
• To open: Pull the handle toward the inlet.
• To close: Push the handle towards the outlet.
NOZZLE
• To change the spray angle rotate the pattern sleeve/bumper. Rotate it clockwise for straight stream and
counterclockwise for wide fog .
• To flush the nozzle, rotate the flow control ring counterclockwise to the FLUSH setting. Rotate slowly back to
the required setting when obstruction is flushed.
• Some nozzles have various flow settings indicated on flow control ring. To change the flow rate, slowly rotate the flow
control ring to the required setting and adjust your engine to provide the rated pressure at the inlet of the nozzle.
• 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 gains due to elevation ( 1/2 psi per foot of
height difference).
FOR USE WITH CAFS
• For optimal CAFS Bubble Structure place the nozzle pattern in straight stream and turn the flow control Ring to FLUSH.
NOTE: Changing the flow control ring without adjusting the pressure will affect your actual flow rate
• i.e, If you change to a higher flow setting, your inlet pressure will decrease and your flow will be less than shown
on the flow control ring. If you change to a lower flow setting, your inlet pressure will increase and your flow
will be more than shown on the flow control ring. Changing the flow changes the reaction force. Pump curves,
hose size and length, elevation, etc., will affect actual results.

Maintenance Instructions

• After use, flush the nozzle with clean water to clean grit and dirt from around exterior moving parts. Doing so will allow the
nozzle to operate as designed.
• Over time the seals and turbine teeth may need replaced. This can be accomplished by purchasing the appropriate Akron
repair kit. Use qualified maintenance mechanics or return the nozzle to Akron Brass for repair.
• Regularly check the baffle screw to be sure it is tight
• Use low temp Lubriplate on metal parts and Parker O-Ring lubricant on O-Rings.
