I. PRODUCT SAFETY INFORMATION

Important:

Before installing and operating this equipment, read & study this manual thoroughly. Proper
installation is essential to safe operation. In addition, the following points should be adhered to in
order to ensure the safety of equipment and personnel:

• All personnel who may be expected to use this equipment must be thoroughly trained in its
safe and proper use.

• Before flowing water from this device, check that all personnel (fire service and civilian) are out
of the stream path. Also, check to make sure stream direction will not cause avoidable
property damage.

• Become thoroughly familiar with the hydraulic characteristics of this equipment, and the
pumping system used to supply it. To produce effective fire streams operating personnel must
be properly trained.

• Open water valve supplying this equipment slowly, so that piping and hose lines fill slowly, thus
preventing possible water hammer occurrence.

• After each use, and on a scheduled basis, inspect equipment per instructions in section VII.

• This nozzle is not designed to be used as a battering ram, sledge hammer, or forcible entry

tool.

• The maximum allowable pressure for this nozzle is 200 psi.

Important:

Open and close the valve slowly to avoid creating a water hammer. Severe water hammer may
cause the compressible bore to become inverted in the nozzle. If this occurs, simply crack the
shut-off until the compressible bore returns to proper position. Continually creating a water
hammer may compromise the integrity of the nozzle. Never intentionally cause water hammer.
