3.4 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.
3.5 ELECTRIC INSTALLATION
For nozzle installation, refer to LIY-500 Remote Control (RC) Monitor Electrical Controls (shipped with TFT monitors or available at
tft.com).
3.6 AUTOMATIC NOZZLE OPERATION
Automatic nozzles operate by sensing the pressure at the nozzle 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.
3.7 PATTERN CONTROL
TFT nozzles have full pattern control from straight stream to wide fog. Turning the stream shaper clockwise (as seen from the operating
position behind the nozzle) moves the shaper to the straight stream position.
For ER versions, press and hold the FOG or STRAIGHT STREAM buttons on the nozzle controls to move the stream shaper. Release
the button when the desired pattern is reached.
Since the stream trim point varies with flow, the stream should be “trimmed” after changing the flow to obtain the straightest and farthest
reaching stream. To properly trim the stream, first open the pattern to narrow fog. Then close the stream to parallel to give maximum
reach. Turning the shaper further forward will cause stream crossover and reduce the effective reach of the nozzle.
3.8 STANDARD/LOW PRESSURE KNOB
For situations where 100 PSI at the nozzle is impractical, the
Master Force dual pressure knob may be switched to low pressure
mode. In the low pressure mode, the nozzle pressure is reduced
by about 50%, while maintaining a usable stream and increasing
the flow. The nozzle operator must be prepared for a change in
reaction when changing modes.
To switch to the low pressure mode, shut off water flow to the
nozzle and turn knob at front of nozzle counterclockwise (when
viewed from front). Nozzle will now operate at reduced pressure.
To return to 100 PSI operation, shut off water flow to the nozzle
and turn knob clockwise.
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.
NOTICE
Turning the shaper further forward will cause stream crossover and reduce the reach of the nozzle.
CAUTION
Dents or nicks in the nozzle tip can seriously affect the stream reach or pattern, which may increase
the risk of injury due to exposure. Care must be taken to avoid dents or nicks in the nozzle tip.
