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.

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

CAUTION

Nozzle must be properly connected. Mismatched or damaged threads may cause nozzle to leak or uncouple under pressure and could cause injury.

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.

&

Streaming currents as water or foam is introduced into the storage tank.

1

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 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.

LIM-030 October 12, 2005 Rev 05

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:

Where:

F

= 29.71 for English units (GPM, INCHES, PSI)

F

= .667 for metric units (LPM, MM, BAR) Note: 1 BAR=100 KPA

Q smooth

D

P pitot

flow in GPM (or LPM) exit diameter in INCHES (or MM) pitot pressure in PSI (or BAR)

Q smooth

2

= F x D P pitot

Step 2: Find pressure loss constant.

Using the results from step 1, use the following equation to calculate the pressure loss constant between the in-line pressure gauge and the nozzle:

Where:

C

P inline

2 2 piping pressure loss constant in GPM /PSI (or LPM /BAR) in-line pressure gauge reading in PSI (or BAR)

Step 3: Calculate flow with automatic nozzle.

Using the pressure loss constant from step 2 and the following equation, the flow with an automatic nozzle can be calculated for your particular installation.

Where:

Q auto

P auto

automatic nozzle flow in GPM (or LPM) nominal nozzle operating pressure in PSI (or BAR)

C =

Q

2 smooth

P - P in-line pitot

Q = (P - P )C auto in-line auto

Mount a graph or table of the results adjacent to the in-line pressure gauge.

Deliver any desired flow by adjustment of pump pressure.

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%.

• Stream trajectory of Masterstream 4000 based on "The Trajectories of Large Fire Fighting Jets" by A.P. Hatton and M.J. Osborne, Reference: "The International Journal of Heat and Fluid Flow", Vol 1 No 1.

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:

4.

Remove debris.

• The cylinder and piston will come out as a unit.

• Remove the small spring and stainless steel poppet from the center of the shaft.

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).
