4.8 NOZZLE INSTALLATION
The nozzle is simply screwed onto the monitor's exit threads. If the nozzle is installed on a Typhoon RC (with electric motors) assure
that the nozzle's actuator does not make contact with the horizontal drive motor housing when the monitor is in its lowest elevation
position.
CAUTION
CAUTION
4.9 PRESSURE GAUGE PORT
There is a ¼" NPT female threaded hole on the back of the monitor and the exit elbow (see Figure 3.4). The holes are plugged from
the factory. If a pressure gauge is desired, unscrew the plug and install the gage using pipe sealant. Make sure the gauge does not
interfere with operation.
4.10 TILLER HANDLE INSTALLATION
For tiller models, the 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.
4.11 DRAINING RESIDUAL WATER
There is no drain on the monitor itself. A drain valve should be installed on the piping to which the monitor is attached.
Monitors, valves, and piping may be damaged if frozen while containing sufficient amounts of
WARNING
water. Such damage may be difficult to detect visually and can lead to possible damage, injury,
or death. Equipment that may be exposed to freezing conditions must be drained immediately
following use to prevent damage.
Structural damage from corrosion can result from failure to drain appliance between uses. Damage
CAUTION
from corrosion can cause injury due to equipment failure. Always drain appliance between uses.
4.12 LADDER MONITOR INSTALLATION
Due to the unique mounting orientations found on ladder trucks, an anti-back-drive mechanism gearbox is included on ladder models
to prevent unintended monitor/nozzle movement due to vibration. The gearbox allows the motor and manual override wheel to turn
the monitor in both directions, while preventing the monitor from back-driving the motor and manual override wheel.
NOTICE
For installations where adequate clearance for the anti-back-drive gearbox is not available, an electronic method to help prevent
unintended monitor/nozzle movement due to vibration is available. The electronic method can be used only if the monitor is always
powered while the truck is in operation. See LIY-500 Section for wiring and programming information.
5.0 OPERATING INSTRUCTIONS
See Remote Control (RC) Monitor Electrical Controls Supplemental Instructions LIY-500 for operation of the Typhoon RC Monitors.
5.1 HANDWHEEL HORIZONTAL ROTATIONAL 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 14 turns of the handwheel will give a 90 degree change in horizontal rotation
direction.
5.2 HANDWHEEL ELEVATION CONTROL
A handwheel controls the monitor's elevation direction. Clockwise rotation of the handwheel lowers the elevation and counterclockwise
raises it. About 18 turns of the handwheel will give the complete 135 degree elevation travel range of the monitor.

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.
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.
The anti-back-drive mechanism adds to the overall size of the monitor. To prevent damage due
to interference, always ensure adequate clearance when installing the monitor.
