3.2 MECHANICAL SPECIFICATIONS
3.3 USE WITH SALT WATER
Use with salt water is permissible provided the equipment is thoroughly cleaned with fresh water after each use. The service life of the
equipment may be shortened due to the effects of corrosion, and is not covered under warranty.
3.4 NOZZLE COUPLINGS
Master Foam nozzles in 250, 350, 500, 750, 1000, and 1250 gpm (950, 1325, 1900, 2900, and 4800 l/min) versions are available with a
2.5 inch coupling (NH, NPSH or BSP).
Master Foam nozzles in 1500 and 2000 gpm (5700 and 7600 l/min) versions have a 3.5” (NH) coupling as standard.
When tightening the coupling, make sure the foam inlet is pointing downward for ease of attaching the concentrate inlet hose.
3.5 ELECTRIC INSTALLATION
Nozzles with electric stream shaper actuation are shipped with a wiring diagram (TFT item #LIM-040). Other documentation is available
on request. ER nozzles are equipped with manual override in case of electrical power failure.
4.0 OPERATION
4.1 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) 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.
On RC Master Foam nozzles, use the FOG and STRAIGHT STREAM buttons on the operator station to change the pattern.
Since the stream trim point varies with flow, the stream should be “trimmed” after establishing a steady flow. To properly trim the stream,
first open to a narrow fog. Then close the stream to parallel to give maximum reach.

CAUTION
Mismatched or damaged waterway connections may cause equipment to leak or uncouple under
pressure. Failure could result in injury. Equipment must be mated to matched connections.
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability to
uncouple the connection, or complete loss of engagement over time. Failure could cause injury. Per
NFPA 1962, if dissimilar metals are left coupled together, an anti-corrosive lubricant should be
applied to the connection and the coupling should be disconnected and inspected at least
quarterly.
WARNING
This device is not rated as ignition proof, explosion proof, or intrinsically safe. Use only in locations
with adequate ventilation and no hazard of flammable vapor buildup.
WARNING
The nozzle reaction is greatest when the shaper is in the straight stream position. Sudden changes
in pattern can cause changes in reaction, leading to loss of footing or an out of control nozzle. The
nozzle operator must be prepared for a change in reaction as the pattern is changed.
NOTICE
Turning the shaper further forward will cause stream crossover and reduce the reach of the nozzle.
NOTICE
The widest pattern is useful for protection and cooling, but does not educt foam.
