4.0 INSTALLATION

See Remote Control (RC) Monitor Electrical Controls Supplemental Instructions (LIY-500) For Tornado RC models.

4.1 STRUCTURAL REQUIREMENTS

The structure that the Tornado Monitor is mounted to must withstand the internal pressure of the monitor as well as shear and
bending forces due to nozzle reaction. Nozzle reaction can be as high as 400 lbs (180 kg) (500 gpm at 200 psi).
For fl anged connections the use of fl at fl anges without raised faces is recommended. Use a ring gasket as defi ned in ASME 16.21
or ISO 7483. Tighten fl ange bolts in an alternating sequence as shown in fi gure 4.1A. Tighten sequentially each bolt or stud three
times with 30%, then 60%, and fi nally 100% of the specifi ed torque in fi gure 4.1B. Tighten to 76-80 ft-lb (100-110 Newton-Meters).

4.2 QUICK CONNECT INLET MOUNTING AND TRAVEL RANGES

The Tornado Monitor is available with various inlet fi ttings. These Inlet Adapters must be oriented upon installation so the Tornado will
point in the desired direction. Figure 4.2A shows examples of Inlet Adaptors and the location of a "Straight Ahead Reference Mark".
This fi gure also gives some information about securing the Tornado to the Inlet Adapter. Travel ranges relative to the Straight Ahead
Reference Mark are shown in Figure 4.2B. Figure 4.2C gives the location of the "Stop Bolts", which are used to limit the travel.
A rotational lock is included on quick connect couplings on RC models. The locking pin also holds the coupling up and out of the
way while orienting the monitor to engage the internal ear into the slot on the adaptor. Hold the pin out, push the coupling up and the
release pin before installing monitor on the adaptor. Once the monitor is properly aligned on the adaptor, hold the pin out while sliding
the coupling down to the adaptor. Rotate the coupling until it is tight. The coupling may become suffi ciently tight before reaching the
next detent position. It is not necessary to over tighten the coupling if the pull pin is between detent positions. Do not use the pull pin
as a lever to tighten or loosen the coupling.

Injury can result from an inadequately supported monitor. The monitor mount must be capable
of supporting the nozzle reaction force which can be as high as 400 lbs (180 kg). Flanges and
pipe made from plastic are inadequate for monitor mounting and must not be used. This monitor
is not recommended for portable use.
