2.5.4 USE OF FOAMJET LX
To increase the expansion ratio, Task Force Tips' "Foamjet
LX" (model FJ-LX-M) may be used. This low expansion
foam tube attaches and removes quickly from the nozzle.
Note: As expansion ratio is increased the reach of the
nozzle will be decreased due to the greater amount of
bubbles in the stream and their inability to penetrate the air.
Figure 2.5.4 gives approximate stream trajectory
information with and without Foamjet LX. Actual results
will vary based on brand of foam, hardness of water,
temperature, etc.
2.5.5 CLEANING AFTER USE
After educting foam it is recommended that water be
educted in through the concentrate hose and inlet. This will
wash out foam concentrate residue in the hose, orifice
plate, and nozzle passages. If not removed, any residue
may dry and adversely affect the accuracy of
proportioning.
2.5.6 USE WITH SALT WATER
Use with salt water is permissible provided nozzle is
thoroughly cleaned with fresh water after each use. The
service life of the nozzle may be shortened due to the
effects of corrosion and is not covered under warranty.
For saltwater compatibility with foam, refer to supplier's
technical data.

particular, check that:
• Coupling and gasket are tight and leak free.
• The desired orifice plate (flow and percentage) is installed.
• Concentrate inlet hose and gasket are damage and leak free.
• Flow passages are unobstructed.
• Baffle is in place and tightened securely.
• Shaper moves freely.
