3.5.4 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.

3.5.5 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, orifi ce plate,
and nozzle passages. If not removed, any residue may dry
and adversely affect the accuracy of proportioning.

3.5.6 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

4.0 MAINTENANCE AND INSPECTION

WARNING
The MASTER FOAM self-educting nozzle requires no routine maintenance. The shaper seal slides on a plastic surface and requires
no grease. The nozzle should be inspected regularly to assure proper operation. In particular, check that:
• Coupling and gasket are tight and leak free.
• The desired orifi ce plate (fl ow and percentage) is installed.
• Concentrate inlet hose and gasket are damage and leak free.
• Flow passages are unobstructed.
• Baffl e is in place and tightened securely.
• Shaper moves freely.

The nozzle may be damaged if frozen while containing suffi cient amounts of water. Such
damage may be diffi cult to detect visually and can lead to possible injury or death. Any time
the nozzle is subject to possible damage from freezing, it must be hydrostatically tested by
qualifi ed personnel before being considered safe for use.
