4.3 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 it’s lowest elevation
position.
CAUTION
The nozzle threads must match the threads of the Typhoon 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.
NOTICE
For nozzles with electric pattern control, a cable with a female, waterproof connector is provided
at the outlet of the Typhoon RC which attaches directly to TFT’s electric Masterstream 1250, 1500
or 2000 nozzle. The cable used is a dual-key, micro type plug assembly. Any other nozzle should
have the corresponding male electrical connector installed. Do not cut off the female connector
on the monitor. This connector is molded onto the cable and must remain in place to maintain
the water tightness of the electrical system.
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 INSTRUCTIONS
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.
4.6 DRAIN
There is no drain on the Typhoon Monitor itself. A drain valve should be installed on the monitor’s inlet piping.
CAUTION
Use with salt water is permissible provided the monitor is thoroughly cleaned with fresh water
after each use. The service life of the monitor may be shortened due to the eff ects of corrosion
and is not covered under warranty.
CAUTION
Structural damage from corrosion can result from failure to drain appliance between uses. Always
drain appliance.
4.7 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
The anti-back-drive gearbox adds to the size of the monitor (see Figure 3.4F), so additional
clearance may be needed to prevent interference with the cab in some installations. The anti-
back-drive gearbox is removable. Contact factory for instructions.
There is also an electronic method to help prevent unintended monitor/nozzle movement due to vibration. This method is provided
for installations where adequate clearance for the anti-back-drive gearbox is not available. The electronic method can only be used
if the monitor is always powered while the truck is in operation. See LIY-500 Section 4.13.3 for wiring and programming information.
5.0 OPERATION
5.1 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 14 turns of the handwheel will give a 90 degree change in horizontal rotation
direction.
5.2 ELEVATION CONTROL
A handwheel controls the monitor’s elevation direction. Clockwise rotation of the handwheel lowers the elevation and counter-
clockwise raises it. About 18 turns of the handwheel will give the complete 135 degree elevation travel range of the monitor.
