4.3 NOZZLE CONNECTION
The Hurricane RC monitor outlet thread types are as shown in figure 3.3. The nozzle is simply screwed onto the Hurricane RC monitor's
exit threads. Insure that the nozzle's coupling does not make contact with the elevation drive housing when the monitor is in its highest
elevation position.
For nozzles with electric pattern control, a waterproof connector wire is provided at the bottom outlet of the Hurricane RC's control
station box. This wire attaches directly to TFT's electric Masterstream 1250 nozzle. The electric actuator box of nozzle must be oriented
to the top side of nozzle for the connection wire to extend 90° above horizontal and 45° below elevation movement. (see figure 4.3 and
refer to Sections 5.12 and 6.6.2 for properly attaching female to male connectors). Any other nozzle should have the corresponding
male electrical connector installed and long enough wire to extend
of the
nozzle.
90° above horizontal and 45° below elevation movement
DO NOT CUT OFF THE FEMALE CONNECTOR ON THE MONITOR. THIS CONNECTOR IS MOLDED ONTO THE WIRE
AND MUST REMAIN ON TO MAINTAIN THE WATER TIGHTNESS OF THE ELECTRICAL SYSTEM.
CAUTION
The nozzle threads must match the threads on the Hurricane RC 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 effects of corrosion can be greatly
delayed by various coatings on the metal such as powder paint, hard anodizing or silicone grease.

TFT's Master Stream 1250 ER Nozzle
Electric Actuator Box must be on the Top
Side for its Edge to line up with Monitor
Waterway Top Body as shown.
4.4 HORIZONTAL ROTATION TRAVEL STOPS
The range of Horizontal (left-right) travel for the Hurricane RC monitor is limited to 450 degrees or 225 degrees from either side of a
nozzle discharge position. Horizontal (left-right) travel stop bolts may be installed in the monitor to limit travel as shown in figure 4.4A and
4.4B. Note that left and right are relative to the “Straight Back Reference Mark” shown in figure 4.4A, and refer to the operator's position
behind the monitor, opposite the nozzle's discharge direction. Also, Figure 4.4A shows the range of travel for the various stop bolt
locations along with installation notes as shown in Figure 4.4B.
