4.8 NOZZLE INSTALLATION
The nozzle is simply screwed onto the monitor’s exit threads. If the nozzle is installed on a Monsoon 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 it’s lowest elevation
position.
4.9 PRESSURE GAUGE 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 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 Monsoon RC monitor itself. A drain valve should be installed on the piping to which the monitor is attached.
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.
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 Monsoon 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 50 turns of the handwheel will give the complete 135 degree elevation travel range of the monitor.
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
Monitors, valves, and piping may be damaged if frozen while containing sufficient amounts of
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.
CAUTION
Structural damage from corrosion can result from failure to drain appliance between uses. Damage
from corrosion can cause injury due to equipment failure. Always drain appliance between uses.
NOTICE
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.
