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 fi lter block located on the nozzle's stream shaper. When the port on the left of the
fi lter 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 fl exible to allow for movement of the stream shaper.
Use only clean fl uid compatible with Buna N Compound (Nitrile). System must be free from all dirt, chips and contaminants.
Replacement fi lter elements are available from TFT (item #M160). Maximum hydraulic pressure is 1000 psi (70 bar, 7000 Kpa) for
Masterstream 1000 or 1250s (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 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.
The electric motor and other components are ignition sources. The electric stream shaper should
WARNING
be operated only in areas where there is adequate ventilation and no hazard of fl ammable 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. For linearly actuating models,
pushing the stream shaper forward (as seen from the operating position behind the nozzle) will result in a straight stream pattern.
Moving the shaper back will result in an increasingly wider pattern.
Since the stream trim point varies with fl ow, the nozzle should be "trimmed" after changing the fl ow to obtain the straightest and farthest
reaching stream. To properly trim a stream, fi rst 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 fi re service training for the proper use of foam.
For Class B fi res, lack of foam or interruption in the foam stream can cause a break in the foam
WARNING
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.
Improper use of foam can result in injury or damage to the environment. Follow foam manufacturer's
WARNING
instructions and fi re service training.
Avoid:
• using wrong type of foam on a fi re, i.e. Class A foam on a Class B fi re
• plunging foam into pools of burning liquid fuels
• causing environmental damage
• directing stream at personnel.
There is a wide variety of foam concentrates. Each user is responsible for verifying that any foam
WARNING
concentrate chosen to be used with this unit has been tested to assure that the foam obtained is
suitable for the purpose intended.
