4.4 TRAVEL STOPS
Stop bolts and adjustment disks can be installed to limit the travel of the monitor in either travel direction. Instructions on how to install
the stop bolts and adjustment disks are shown below.
Figure 4.4
4.5 NOZZLE INSTALLATION
The nozzle is simply screwed onto the monitor’s exit threads. If the nozzle is installed on a Tornado 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.
4.6 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.
4.7 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.
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.
