6.0 OPERATION
The TFT VORTEX Nozzle allow the stream pattern to be in
fi
nitely varied from a straight stream to a uniformly dispersed VORTEX
pattern. Typical stream results are shown in Figure 6.0A.

The VORTEX includes a label indicator for the user to con
fi
rm when the VORTEX is at the straight stream or in a VORTEX dispersed
position. As seen from the operating position behind the nozzle, actuating the VORTEX indicator counterclockwise moves into the
straight stream position. Actuating the VORTEX indicator clockwise will result in an increasingly wider pattern until reaching the full
VORTEX pattern.

Pivoting the vanes has virtually no e
ff
ect on the
fl
ow area or ability to pass large debris. As a result, discharge pressure and
fl
ow rate
remain constant regardless of stream pattern.
Manual override is possible on ER models by using the 5/16” hex head to drive the motor shaft. Manual versions include a crank
for actuating the VORTEX. Turning the shaft clockwise moves the nozzle towards a straight stream pattern. Turning the shaft
counterclockwise moves the nozzle to the dispersed VORTEX spray pattern. Do not force the shaft further after it stops
fi
rmly at each
end of stroke. Exceeding 60 in-lb (6.8 N·m) can damage the actuator.
CAUTION
The electric drives are current limited but may still produce enough force to cause injury. To avoid
injury from a moving monitor:
• Be aware that the monitor may be remotely operated
• Keep hands and
fi
ngers away from pinch points on the monitor
• Never operate the manual override while electric controls are in operation
