1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identifi ed by a safety alert symbol and a signal word to indicate the level of risk involved with a particular
hazard. Per ANSI standard Z535.6-2011, the defi nitions of the four signal words are as follows:
DANGER DANGER indicates a hazardous situation which, if not avoided, will result in death or serious
injury.
WARNING WARNING indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor
or moderate injury.
NOTICE NOTICE is used to address practices not related to physical injury.

2.0 SAFETY
DANGER An inadequate supply of nozzle pressure and/or fl ow will cause an ineff ective stream and can
result in injury, death, or loss of property. See fl ow graphs or call 800-348-2686 for assistance.
WARNING This equipment is intended for use by trained personnel for fi refi ghting. Their use for other
purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
WARNING WARNING Injury can result from an inadequately supported monitor. The monitor mount must
be capable of supporting 661 lbs (301 kg) of nozzle reaction force.

WARNING Some volatile liquids can be ignited by static discharge.
Static build-up can occur from:
• Electrochemical separation of charge as water drains through low conductivity, refi ned
products
• Applying foam over a low conductivity liquid of suffi cient depth to retain the charge created as
the foam blanket drains
• Streaming currents as water or foam is introduced into the storage tank1
WARNING Water is a conductor of electricity. Application of water solutions on high voltage equipment can
cause injury or death by electrocution. The amount of current that may be carried back to the
nozzle will depend on the following factors:
• Voltage of the line or equipment
• Distance from the nozzle to the line or equipment
• Size of the stream
• Whether the stream is solid or broken
• Purity of the water2
WARNING The stream exiting a nozzle is very powerful and capable of causing injury and property damage.
Make sure the nozzle is securely attached and pointing in a safe direction before water is turned
on. Use care in directing the stream.
WARNING The nozzle may be damaged if frozen while containing signifi cant 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 due to freezing, it must be tested by qualifi ed personnel before being
considered safe for use.
CAUTION Nozzle must be mated to a hose with matched threads. Mismatched or damaged threads may
cause nozzle to leak or uncouple under pressure and could cause injury.
CAUTION Do not connect aluminum to brass or brass to aluminum. Dissimilar metals coupled together
can cause galvanic corrosion that will freeze the threaded joint or cause complete loss of thread
engagement. If dissimilar metals must be coupled together, the eff ects of corrosion can be greatly
delayed by various coatings on the metal such as powder paint, hard anodizing, or silicone grease.
NOTICE To prevent mechanical damage, do not drop or throw equipment.

3.0 GENERAL INFORMATION
TFT MASTER FOAM nozzles are rugged self-educting foam fi xed orifi ce fog nozzles made from heat treated, hard anodized
aluminum.
MASTER FOAM nozzles come in three ranges. Each range determine water fl ow with baffl e options. The removable baffl e allows for
fl ushing debris. On most MASTER FOAM nozzles, changing the baffl e changes the nozzle’s water fl ow rate.
A vacuum created by water velocity pulls foam concentrate into the nozzle. Foam concentrate enters the peripheral jet uniformly
at discharge without causing turbulence. Mixing and aeration happen immediately resulting in superior stream quality and reach.
MASTER FOAM nozzles use no clog prone small passageways.
MASTER FOAM Nozzles come with calibrated orifi ce plates to set the foam percentage. Orifi ce plates are easily inserted into the
side foam port. A concentrate hose with camlock fi tting (military standard MS27019) connects to the foam port capturing the orifi ce
plate.
Fog angle is user adjustable between 90° wide fog and straight stream. Higher fl ow (1000 GPM and higher) nozzles provide a set
screw for locking in a fog angle.

3.3 ELECTRICAL INSTALLATION
Nozzles with electric stream shaper actuation are shipped with a wiring diagram (TFT item #LIN-040). Other documentation is
available on request. The actuator is not rated as ignition proof, explosion proof or intrinsically safe. NOTE: Masterstream 1000,
1250s, 1250, 1500 and 2000 nozzles are equipped with manual override in case of electrical power failure. Refer to fi gure 1E for
manual override instructions.
WARNING The electric motor and other components are ignition sources. The electric stream shaper should
be operated only in areas where there is adequate ventilation and no hazard of fl ammable vapor
buildup.
3.4 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 eff ects of corrosion and is not covered under warranty.
For saltwater compatibility with foam, refer to foam supplier’s technical data
3.5 NOZZLE COUPLING
The MASTER FOAM nozzle is available with 2.5 inch female threads (NH, NPSH or BSP) for 250, 350, 500, 750, 1000, and 1250
versions. 1500 and 2000 version have a 3.5” coupling as standard. When tightening the coupling, make sure the foam inlet is
pointing downward for ease of attaching the concentrate inlet hose.

4.2 USE WITH FOAM
Refer to fi re service training for the proper use of foam.
WARNING For Class B fi res, lack of foam or interruption in the foam stream can cause a break in the foam
blanket and greatly increase the risk of injury or death.
Assure that:
• Application rate is suffi cient (see NFPA 11 or foam manufacturer’s recommendations)
• Enough concentrate is on hand to complete task (see NFPA for minimum duration time
requirements)
• Foam logistics have been carefully planned.
Allow for such things as:
• Storage of foam in a location not exposed to the hazard it protects
• Personnel, equipment, and technique to deliver foam at a rapid enough rate
• Removal of empty foam containers
• Clear path to deliver foam, as hoses and other equipment and vehicles are deployed
WARNING Improper use of foam can result in injury or damage to the environment. Follow foam
manufacturer’s instructions and fi re service training to avoid:
• Using wrong type of foam on a fi re, i.e. Class A foam on a Class B fi re.
• Mishandling of concentrates, some of which are fl ammable.
• Plunging foam into pools of burning liquid fuels.
• Causing environmental damage.
• Directing stream at personnel.
WARNING There are a wide variety of foam concentrates. Each user is responsible for verifying that any
foam concentrate chosen is suitable for the purpose intended.

4.2.4 SETTING FOAM PERCENTAGE
The foam percentage is controlled by an orifi ce plate that is installed in the nozzle at the mouth of the concentrate inlet. Depending
on the nozzle chosen, the MASTER FOAM comes with orifi ce plates for 0.5%, 1%, 3%, or 6%. Each orifi ce plate is marked with the
percentage and nozzle fl ow rate. The fl ow rate on the orifi ce plate must match the fl ow rate marked on the nozzle’s baffl e. The chart
in fi gure 4.2.4b gives the nominal rates of foam usage. Accuracy of proportioning is fairly insensitive to nozzle inlet pressure. The
graph in fi gure 4.2.4c gives expected percentages for various inlet pressures.

Foam pickup in the widest fog position (90°) is not guaranteed.
4.2.5 USE OF FOAMJET LX
To increase the expansion ratio, Task Force Tips’ “Foamjet LX” (model FJ-LX-M) may be used on nozzles rated to 750 gpm. 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 5.0.1 gives
approximate stream trajectory information with and without Foamjet LX. Actual results will vary based on brand of foam, hardness
of water, temperature, etc.
4.2.6 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 aff ect the
accuracy of proportioning.

6.0 OPERATION
6.1 PATTERN CONTROL
The MASTER FOAM’s spray pattern is adjustable from straight stream to a 90° wide fog. On models with manual shapers turning the
stream shaper clockwise (as seen from the operating position behind the nozzle -see fi gure 6.1A.) moves the shaper to the straight
stream position. Turning the shaper counterclockwise will result in an increasingly wider pattern. Only 90° of rotation is required to go
from wide fog to a straight stream. The widest pattern is useful for protection and cooling but doesn’t educt foam.
RC Masterfoam nozzles actuate diff erently than manual versions. A drive pin controls the location of the shaper along cam grooves
manipulating the stream (see Fig. 6.1B). When the drive pin is at the forward end stop the nozzle will project a straight stream.
Likewise, at the back end stop the nozzle will project a wide fog pattern.
Since the stream trim point varies with fl ow, the stream should be “trimmed” after establishing a steady fl ow. To properly trim the
stream, fi rst open to a narrow fog. Then close the stream to parallel to give maximum reach. NOTE: Turning the shaper further
forward will cause stream crossover and reduce the reach of the nozzle.
WARNING Nozzle reaction will vary as supply conditions change: such as opening or closing other nozzles,
hose line kinks, changes in pump settings, etc. Changes in spray pattern or fl ushing will also
aff ect nozzle reaction. The nozzle operator must always be prepared in the event of these
changes. Failure to restrain nozzle reaction can cause fi refi ghter injury from loss of footing and/
or stream protection.

6.2 FLUSHING DEBRIS
Debris in the water may get caught inside the nozzle. This trapped material will cause poor stream quality, shortened reach and
reduced fl ow. To remove debris trapped in the nozzle:
• Shut off fl ow to the nozzle.
• Unscrew baffl e using socket specifi ed in fi gure 6.1
• Remove debris. Flow water to fl ush if necessary.
• Reinstall baffl e. Tighten to approximately 30 ft-lbs (40 Newton-Meters).
WARNING Large amounts or pieces of debris may be unfl ushable and can reduce the fl ow of the nozzle
resulting in an ineff ective fl ow. In the event of a blockage, it may be necessary to retreat to a safe
area, uncouple the nozzle and remove debris.
