1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identifi ed by a safety alert symbol and a signal word to indicate the level of risk involved with a particular
hazard. Per ANSI standard Z535-2011, the defi nitions of the four signal words are as follows:
DANGER DANGER indicates a hazardous situation which, if not avoided, will result in death or serious
injury.
WARNING WARNING indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor
or moderate injury.
NOTICE NOTICE is used to address practices not related to physical injury.
2.0 SAFETY
The operation of this monitor can be dangerous. The following must be observed at all times.
WARNING An inadequate supply of nozzle pressure and/or fl ow will cause an ineff ective stream and can
result in injury, death, or loss of property. See fl ow graphs or call 800-348-2686 for assistance.
WARNING Injury or death may occur by attempting to use a damaged monitor. Before using the monitor
inspect it for damage resulting from, but not limited to:
• Failure to drain monitor followed by exposure to freezing conditions.
See section DRAINING RESIDUAL WATER for instructions.
• Exposure of monitor to temperatures in excess of 160 degrees F.
• Missing parts, physical abuse, exposure to severe chemicals.
• Deformed or cracked fl anges damaged as a result of improper installation.
- Excessive bolt torque
- Wrong tightening sequence
WARNING Injury can result from an inadequately supported monitor. The monitor mount must be capable of
supporting 400 lbs (180 kg) of nozzle reaction force.
WARNING The stream exiting a monitor is very powerful and capable of causing injury and property damage.
Make sure the monitor is securely attached to the base and pointing in a safe direction before
water to the monitor is turned on. Use care in directing the stream.
WARNING The monitor may be damaged if frozen while containing suffi cient amounts of water. Such damage
may be diffi cult to detect visually and can lead to possible injury or death. Any time the monitor is
subject to possible damage from freezing, it must be hydrostatically tested by qualifi ed personnel
before being considered safe for use.
WARNING Do not attempt to modify the oscillating mechanism to fi t any other monitor. To do so will cause
the reaction force of the nozzle to be misaligned with the center of rotation. The monitor may spin
very fast and could cause injury or death.
WARNING Keep hands and fi ngers away from moving parts of the oscillating unit when water is fl owing.
There are moving parts that can pinch fi ngers and hands.
WARNING This equipment is intended for use by trained personnel for fi refi ghting. Their use for other
purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
CAUTION The electric monitor may be remotely operated. The electric drives are current limited but may
still produce enough force to cause injury. Keep hands and fi ngers away from pinch points on
the monitor.
CAUTION Do not use the manual override knobs while the electric controls are in operation. The electric
drives produce enough torque to cause injury.
CAUTION Maximum fl ow and pressure is 500 gpm (1900 l/min) and 200 psi (14 bar). Damage or injury may
result if the monitor is operated beyond these limits.
CAUTION On many vehicle installations, the monitor is the highest point on the apparatus. Be sure there
is suffi cient clearance to safely pass under any doors or overhead obstructions. Always check
parked position of the monitor before moving.
NOTICE To prevent mechanical damage, do not drop or throw equipment.

4.0 INSTALLATION
See Remote Control (RC) Monitor Electrical Controls Supplemental Instructions (LIY-500) For Tornado RC models.
4.1 STRUCTURAL REQUIREMENTS
The structure that the Tornado Monitor is mounted to must withstand the internal pressure of the monitor as well as shear and
bending forces due to nozzle reaction. Nozzle reaction can be as high as 400 lbs (180 kg) (500 gpm at 200 psi).
For fl anged connections the use of fl at fl anges without raised faces is recommended. Use a ring gasket as defi ned in ASME 16.21
or ISO 7483. Tighten fl ange bolts in an alternating sequence as shown in fi gure 4.1A. Tighten sequentially each bolt or stud three
times with 30%, then 60%, and fi nally 100% of the specifi ed torque in fi gure 4.1B. Tighten to 76-80 ft-lb (100-110 Newton-Meters).

WARNING Injury can result from an inadequately supported monitor. The monitor mount must be capable
of supporting the nozzle reaction force which can be as high as 400 lbs (180 kg). Flanges and
pipe made from plastic are inadequate for monitor mounting and must not be used. This monitor
is not recommended for portable use.
4.2 QUICK CONNECT INLET MOUNTING AND TRAVEL RANGES
The Tornado Monitor is available with various inlet fi ttings. These Inlet Adapters must be oriented upon installation so the Tornado will
point in the desired direction. Figure 4.2A shows examples of Inlet Adaptors and the location of a “Straight Ahead Reference Mark”.
This fi gure also gives some information about securing the Tornado to the Inlet Adapter. Travel ranges relative to the Straight Ahead
Reference Mark are shown in Figure 4.2B. Figure 4.2C gives the location of the “Stop Bolts”, which are used to limit the travel.
A rotational lock is included on quick connect couplings on RC models. The locking pin also holds the coupling up and out of the
way while orienting the monitor to engage the internal ear into the slot on the adaptor. Hold the pin out, push the coupling up and the
release pin before installing monitor on the adaptor. Once the monitor is properly aligned on the adaptor, hold the pin out while sliding
the coupling down to the adaptor. Rotate the coupling until it is tight. The coupling may become suffi ciently tight before reaching the
next detent position. It is not necessary to over tighten the coupling if the pull pin is between detent positions. Do not use the pull pin
as a lever to tighten or loosen the coupling.

4.3 NOZZLE INSTALLATION
The nozzle is simply screwed onto the monitor’s exit threads. If the nozzle is installed on a Tornado RC (with electric motors) assure
that the nozzle’s coupling does not make contact with the horizontal drive motor housing and actuator when the monitor is in its
lowest elevation position.
CAUTION The nozzle threads must match the threads of the Tornado monitor in both size and type.
Mismatched or damaged threads may cause the nozzle to leak or uncouple under pressure and
could cause injury.
CAUTION Do not connect aluminum to brass or brass to aluminum. Dissimilar metals coupled together
can cause galvanic corrosion that will freeze the threaded joint or cause complete loss of thread
engagement. If dissimilar metals must be coupled together, the eff ects of corrosion can be greatly
delayed by various coatings on the metal such as powder paint, hard anodizing, or silicone grease.
4.4 PRESSURE GAGE PORT
There is a ¼” NPT female threaded hole on the back of the monitor and the exit elbow.The holes are plugged from the factory. If
a pressure gage is desired, unscrew the plug and install the gage using pipe sealant. Make sure the gage does not interfere with
operation.
4.5 HANDLE INSTALLATION
Mounting Screw
The tiller handle is shipped loose from the monitor and must be
installed to complete the installation process. When installing the
tiller handle, be sure to coat the threads of the mounting screw
with the Loctite supplied in the hardware packet.
Fig 4.5 Tiller Handle Installation
4.2.1 TRAVEL STOPS
Stop bolts and adjustment disks can be installed to limit the travel of the monitor in either travel direction. Instructions on how to install
the stop bolts and adjustment disks are shown below.

4.6 DRAINING RESIDUAL WATER
There is no drain on the Tornado Monitor itself. A drain valve should be installed on the piping to which the monitor is attached.
WARNING All monitors, valves and standpipes exposed to freezing conditions must be drained immediately
following use to prevent damage. To drain a standpipe, a drainage port must be opened
underground below the frost depth to keep water out of the standpipe until the next use.
5.0 OPERATION OF TILLER MONITORS
5.1 SPRAY TRAJECTORY ADJUSTMENT
On the Tiller Bar model the horizontal rotation is changed by pushing or pulling horizontally on the Tiller Handle. Twisting the Rotation
Locking Knob clockwise will increase the drag on the swivel joint to “lock” the monitor in a particular direction.
CAUTION Injury can result from the monitor changing direction due to an off center nozzle reaction. An off
center nozzle reaction may be caused by debris in the nozzle causing an asymmetrical stream.
Always keep the rotation lock tight when not rotating the monitor. Always keep one hand on
the tiller handle when loosening the locking knob. Where continuous 360 degree rotation of the
monitor is not needed it is recommended that the Horizontal Rotation Stop Bolts be installed to
reduce any chance of the monitor spinning due to an off center nozzle reaction caused by debris
trapped in the nozzle.
6.0 OPERATION OF OSCILLATING MONITORS
6.1 HORIZONTAL ROTATION CONTROL
A handwheel controls the monitor’s horizontal rotation direction. Clockwise rotation of the handwheel moves the nozzle to the left and
counter-clockwise rotation to the right. Approximately 8.5 turns of the handwheel will give a 90 degree change in horizontal rotation
direction.
6.2 ELEVATION CONTROL
A handwheel controls the monitor’s elevation direction. Clockwise rotation of the handwheel raises the elevation and counterclockwise
lowers it. About 13 turns of the handwheel will give the complete 135 degree elevation travel range of the monitor.
WARNING Do not attempt to modify the oscillating mechanism to fi t any other monitor. To do so will cause
the reaction force of the nozzle to be misaligned with the center of rotation. The monitor may spin
very fast and could cause injury or death.
6.3 TO ENGAGE THE OSCILLATING MECHANISM
If the nozzle moves freely left to right by hand, the oscillating
mechanism is not engaged. To engage, ensure the black knob on
the side of the oscillator is released, and move the nozzle from one
side to the other until the black knob clicks into the groove on the
spring canister. The minimum fl ow required to oscillate is 175 gpm
(650 l/min).
The oscillating mechanism is equipped with a safety device that
prevents damage to the gear train in case the oscillator comes in
contact with an object. The safety device will allow the mechanism
to continue to oscillate the portion of its sweep path not blocked by
the obstruction. The safety mechanism also allows the oscillating
mechanism to sweep vertically without disengaging the oscillator.
Once obstruction is removed, sweep pattern will return to normal.

NOTICE The ends of the covered area will receive more water than the center because the oscillator must
slow down, stop, and reverse direction at the end of each sweep. If the center area of coverage
needs more cooling, it may be necessary to occasionally narrow the area of coverage or direct
the stream manually.
6.4 TO DISENGAGE THE OSCILLATING MECHANISM
To operate the oscillating monitor manually, pull then twist the black knob located on the side of the monitor. Twisting will lock the knob
in the disengaged position. The crank, rod, and spring canister will continue to move. Move the nozzle to the desired position by hand.

6.5 COVERAGE AREA OF OSCILLATING MONITOR
To adjust the area of coverage, refer to fi gure 6.3.
Engage the oscillating mechanism once the desired
angle has been set.
Oscillation speed: The chart shows how many times
per minute the oscillator makes one complete cycle
as a function of fl ow. The higher the fl ow, the faster
it oscillates.
For nozzle reach, refer to the operating manual
for the specifi c nozzle. For reach with oscillation,
subtract 20% from the distance

NOTICE The type of nozzle and fl ow pressure are critical to the coverage area. The graph shows coverage
area based on the movement capability of the oscillating mechanism. Actual coverage will
depend on fl ow, pressure, type of nozzle, angle of fog pattern and wind conditions.
7.0 OPERATION OF RC MONITORS
See Remote Control (RC) Monitor Electrical Controls Supplemental Instructions LIY-500 for operation of the Tornado RC Monitors.

8.0 RECOMMENDED PARK POSITION
For truck mounted applications it is recommended that the monitor be parked in a position such that the monitor’s nozzle rests
against a bracket or support surface. If a support surface is not available, run the elevation against one of its travel stops to take some
of the backlash out of the gear drive. This will minimize bouncing of the nozzle when the apparatus is traveling. Always be sure the
monitor is properly parked before moving the truck and know the overall height to avoid damage from overhead obstructions such
as doors or bridges.
See Remote Control (RC) Monitor Electrical Controls Supplemental Instructions (LIY-500) for information on programming DEPLOY,
OSCILLATE and PARK position Tornado RC models.
8.1 OVERRIDE KNOBS
11/16” (18mm) HEX
In the event of electrical system failure on the monitor or fi re truck
the Tornado RC Monitor is factory supplied with knobs so the
monitor may be manually operated. To make the Tornado RC more
compact the manual override knobs may be removed. The drive
shafts have a hex so an 11/16” wrench or socket may be used for
manual override. The wrenching hexes are shown in fi gure 8.1.

9.3 STREAM STRAIGHTENERS
9.3.1 STREAM STRAIGHTENERS WITH STACKED TIPS
Turbulence though the Tornado Monitor is very low but stream quality and reach can be improved with the use of the integral stream
straightener on the TFT stacked tip nozzle. See fi gure 8.2 for the TFT stream straightener friction loss.
9.3.2 STREAM STRAIGHTENERS WITH FOG NOZZLES
When using a fog nozzle for fl ows below 300 gpm (1,100 l/min), it is recommended that no stream straightener be used since the
fog nozzle’s fl ow path serves as a stream straightener. Above 300 gpm (1,100 l/min), TFT’s 5 inch Stream Straightener will generally
improve a fog nozzle’s stream.
