4.5 PRESSURE GAGE PORT
There is a ¼” NPT female threaded hole located behind the elevation hand wheel for the installation of a pressure gage if desired. This
hole has pipe plug installed from the factory. Unscrew the pipe plug and install the gage using pipe sealant. Make sure that the gage
does not interfere with the handwheel.
4.6 AUTOMATIC DRAIN
There is an automatic drain on the HURRICANE RC installed from factory, that will empty the water from the low point of the lower bend
to prevent freezing (Figure 3.2). This valve will close automatically when the internal pressure in the monitor reaches approximately 5
psi (6.3 bar) and will reopen again when the pressure drops to this point. Refer to Section 5.3 for disabling the automatic drain if
desired.
A secondary drain valve should be installed on the monitor's inlet piping to drain water in the riser.
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 figures
4.4A, and refer to the operator's position behind the
monitor, opposite the nozzle's discharge direction.
Also, Figures 4.4A shows the range of travel for the
various stop bolt locations along with installation
notes as shown in Figure 4.4B.
