4.1 STRUCTURAL REQUIREMENTS FOR MONITOR MOUNTING
The structure that the Monsoon 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 1,500 lbs (700 kg) (2000 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 4A. Tighten to 76-80 ft-lb (100-110
Newton-Meters).
Tighten sequentially each bolt three times.

WARNING
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 1500 lbs (700 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.
