2.0 GENERAL INFORMATION
The Task Force Tips Masterstream Series Nozzles are automatic pressure control deluge nozzles. These automatic nozzles operate by
sensing the pressure at the nozzle's inlet and adjusting the discharge opening to maintain a constant pressure throughout the flow
range of the nozzle. While flowing, the stream pattern can be varied from wide fog to straight stream. Trapped debris can be removed
without the use of tools.
These nozzles are constructed of hardcoat anodized aluminum and UV resistant rubber. Their rugged construction is compatible with
the use of fresh water as well as firefighting foam solutions. A summary of each nozzle's characteristics is shown in the table below.

NOTES ON ABOVE TABLE:
! Other threads, coupling sizes or connector styles can be specified at time of order.
! Masterstream 1250 nozzle is also available in selectable gallonage or fixed orifice models. See catalog for details.
! Masterstream 2000 and 4000 nozzles are field adjustable within the range of pressures shown.
! For long term installations, it is recommended that the threads be greased before installing the nozzle.
OPERATING NOTE ABOUT AUTOMATIC NOZZLES: The automatic nozzle is considerably different than "conventional" nozzles
because of basic changes in the operating principle. These differences not only assure the most effective operation under a variety of
conditions, but will also utilize the available water supply most efficiently. It is important that nozzle operators, pump operators, and
officers be fully aware of these differences. Therefore, proper instruction is required for safe and effective operations.
WARNING
This equipment is intended for use by trained personnel for firefighting. Their use for other
purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
CAUTION
Nozzle must be properly connected. Mismatched or damaged threads may cause nozzle to leak or
uncouple under pressure and could cause injury.
CAUTION
Do not couple aluminum to brass. Dissimilar metals coupled together can cause galvanic corrosion
that can result in inability to unscrew threads or complete loss of thread engagement.
WARNING
Injury can occur from an inadequately supported nozzle. The mounting must be capable of
supporting the nozzle reaction force which can be in excess of 2300 lbs (4000 GPM at 120 PSI).
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, refined
products.
& Applying foam over a low conductivity liquid of sufficient depth to retain the charge created
as the foam blanket drains.
1
& Streaming currents as water or foam is introduced into the storage tank.
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
2
& Purity of the water

2.1 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.
2.2 VARIOUS MODELS AND TERMS
The spray pattern is changed from wide fog to straight stream by means of the "stream shaper". Models are available with five
different methods to move the stream shaper as shown in figures 1A - 1E. See catalog for model numbers and details.

FIG 1 - Methods for Moving Stream Shaper
LIM-030 January 20, 2006 Rev 06
2.3 HYDRAULIC INSTALLATION
On nozzles with hydraulic stream shaper actuation, the hydraulic system is connected to the nozzle with two 1/8"-27 NPT (1/4”-18 NPT
on Masterstream 4000) female ports on the filter block located on the nozzle's stream shaper. When the port on the left of the filter block
(as seen from behind the nozzle) is pressurized, the shaper moves back into the wide fog position. Pressurizing the right port moves
the shaper forward into straight stream. Hydraulic lines must be flexible to allow for movement of the stream shaper.
Use only clean fluid compatible with Buna N Compound (Nitrile). System must be free from all dirt, chips and contaminants.
Replacement filter elements are available from TFT (item #M160). Maximum hydraulic pressure is 1000 psi (70 bar, 7000 Kpa) for
Masterstream 1250 or Masterstream 2000 Nozzles. (1500 psi, 105 bar, 10500 Kpa for Masterstream 4000 Nozzle).
2.4 ELECTRIC INSTALLATION
Nozzles with electric stream shaper actuation are shipped with a wiring diagram (TFT item #LIM-040). Other documentation is
available on request. The actuator is not rated as ignition proof, explosion proof, or intrinsically safe. NOTE: Masterstream 1250 and
Masterstream 2000 nozzles are equipped with manual override in case of electrical power failure. Refer to figure 1D 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 flammable vapor
buildup.
2.5 PATTERN CONTROL
TFT's Masterstream Series nozzles have full pattern control from straight stream to wide fog. On models with manual shapers, turning
the stream shaper clockwise (as seen from the operating position behind the nozzle) moves the shaper to the straight stream position.
Turning the stream shaper counterclockwise will result in an increasingly wider pattern.
Since the stream trim point varies with flow, the nozzle should be "trimmed" after changing the flow to obtain the straightest and farthest
reaching stream. To properly trim a stream, first open the pattern to 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 effective reach of the nozzle.
2.6 USE WITH FOAM
The Masterstream Series nozzles may be used with foam solutions. Refer to fire service training for the proper use of foam.
WARNING
For Class B fires, 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 sufficient (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 fire service training.
Avoid using wrong type of foam on a fire, i.e. Class A foam on a Class B fire; Plunging foam into pools of burning liquid fuels; Causing
environmental damage; Directing stream at personnel.
WARNING
There is a wide variety of foam concentrates. Each user is responsible for verifying that any foam
concentrate chosen to be used with this unit has been tested to assure that the foam obtained is
suitable for the purpose intended.
2.6.1 FOAMJET LX WITH MASTERSTREAM 1250 NOZZLE
To increase the expansion ratio, Task Force Tips "Foamjet LX" (model FJ-LX-M) may be used with the Masterstream 1250 nozzle. This
low expansion foam tube attaches and detaches quickly from the nozzle. Adjust nozzle spray pattern to give best foam quality. 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. Generally the reach with foam is approximately 10% less than with water only. Actual results will vary based
on brand of foam, hardness of water, temperature, etc.
3.0 AUTOMATIC NOZZLE OPERATION
Automatic nozzles operate by sensing the pressure at the nozzle's inlet and adjusting the discharge opening to maintain a constant
pressure throughout the flow range of the nozzle. For example, when the pressure at the inlet increases, the exit area is automatically
increased until the inlet pressure returns to the nominal pressure of the nozzle.
Note: Inlet pressure of a Masterstream Series nozzle will stabilize at the nominal pressure (within 5%). This stabilization may take as
long as half a minute after a change in inlet pressure.

3.3 DETERMINING FLOW WITH PRE-PIPED MONITORS
The simplest procedure to determine flow with automatic nozzles is with a flow meter. If a flow meter is unavailable, then the flow may
be estimated using pressure loss data between the nozzle and an in-line pressure gauge at the pump or considerably upstream from
the nozzle. Data is taken with a smooth bore nozzle and handheld pitot gauge. Note: Equations assume no substantial change in
elevation between in-line pressure gauge and nozzle.
Step1: Determine flow of smooth bore nozzle.
Flow water with a smooth bore nozzle and record the nozzle's size, pitot pressure and in-line pressure gauge reading. The smooth
bore nozzle's flow is calculated from the Freeman formula:

3.4 STREAM TRAJECTORY DATA
Figures 4A, 4B and 4C give the stream trajectory for the Masterstream Series nozzles at various flows.
Notes on trajectory graphs:
• Graphs show approximate effective stream trajectory at 30 degrees elevation in no wind conditions. Distance
to last water drops approximately 10% farther.
• Trajectories shown are for water. The addition of foam is expected to decrease the reach by 10%.
• Tail or head winds of 20 MPH (30 KPH) may increase or decrease the range approximately 30%.

4.0 FLUSHING DEBRIS
Debris in the water may get caught inside the nozzle. This trapped material will cause poor stream quality, shortened reach and
reduced flow. To remove debris trapped in the nozzle:
1. Shut off flow to the nozzle.
2. Move the stream shaper to the wide fog position.
3. Carefully unscrew and remove the nozzle's piston/cylinder.
Notes on Masterstream 1250 Nozzle:
• The cylinder is under about 25 lbs (11Kgf) of spring force. The spring must be
compressed to reinstall.
• A long white push rod is part of the cylinder assembly. Pull cylinder straight out until push
rod clears shaft.
Notes for Masterstream 2000 & Masterstream 4000 Nozzles:
• The cylinder and piston will come out as a unit.
• Remove the small spring and stainless steel poppet from the center of the shaft.
4. Remove debris.
5. Reassemble the nozzle.
Figures 5A, 5B & 5C show the pieces that are removed during the flush procedure.
WARNING
Large amounts of debris may be unflushable and can reduce the flow of the nozzle resulting in an
ineffective flow. In the event of a blockage, it may be necessary to retreat to a safe area.

5.0 MAINTENANCE
When reassembling the nozzle after repairs or for preventive maintenance, coat the seal on the piston, the inner bore of the cylinder
and the shaft slide surface with a waterproof lubricant such as Dow Corning #44 Silicone Grease. Lubrication is required to assure
continued smooth operation. The frequency of lubrication will depend on frequency of usage and storage conditions. Nozzles must be
checked regularly to assure proper operation. See figures 5A, 5B and 5C for the nozzle lubrication points.
STORAGE: Store the Masterstream 4000 Hydraulic Nozzle in the Full Fog (retracted) position.
Contact factory for parts lists and exploded views for particular models. Each nozzle is identified by a serial number located on the
nozzle's stream shaper (see figure 1).
6.0 WARRANTY
Task Force Tips, Inc., 2800 East Evans Avenue, Valparaiso, Indiana 46383-6940 ("TFT") warrants to the original purchaser of its
Masterstream Series nozzles ("equipment"), and to anyone to whom it is transferred, that the equipment shall be free from defects in

equipment to TFT, at 2800 East Evans Avenue, Valparaiso, Indiana 46383-6940, within a reasonable time after discovery of the defect.
TFT will examine the equipment. If TFT determines that there is a defect attributable to it, TFT will correct the problem within a
reasonable time. If the equipment is covered by this limited warranty, TFT will assume the expenses of repair.
If any defect attributable to TFT under this limited warranty cannot be reasonably cured by repair or replacement, TFT may elect to
refund the purchase price of the equipment, less reasonable depreciation, in complete discharge of its obligations under this limited
warranty. If TFT makes this election, claimant shall return the equipment to TFT free and clear of any liens and encumbrances.
This is a limited warranty. The original purchaser of the equipment, any person to whom it is transferred, and any person who is an
intended or unintended beneficiary of the equipment, shall not be entitled to recover from TFT any consequential or incidental
damages for injury to person and/or property resulting from any defective equipment manufactured or assembled by TFT. It is agreed
and understood that the price stated for the equipment is in part consideration for limiting TFT's liability. Some states do not allow the
exclusion or limitation of incidental or consequential damages, so the above may not apply to you.

provide reasonable maintenance) or if there have been accidents to the equipment or if it has been repaired or altered by someone
else.
