See Remote Control (RC) Monitor Electrical Controls Supplemental Instructions (LIY-500) for Tornado RC models.
4.1 STRUCTURAL REQUIREMENTS
WARNING
Reaction forces generated by master stream
fl
ows are capable of causing injury and property
damage if not properly supported. Monitors should be securely installed by quali
fi
ed individuals.
• Mounting objects must be capable of withstanding maximum nozzle reaction force listed in
SPECIFICATIONS.
• The monitor must be securely mounted to rigid support members.
• Do not use
fl
anges or pipe made from plastic for monitor mounting.
• Torque all fasteners to speci
fi
ed values.
The structure that the 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).
For
fl
anged connections, the use of
fl
at
fl
anges without raised faces is recommended. Use a ring gasket as de
fi
ned in ASME 16.21
or ISO 7483. Tighten
fl
ange bolts in an alternating sequence as shown below. Tighten sequentially each bolt or stud three times to
30%, then 60%, and
fi
nally 100% of the speci
fi
ed torque. Tighten to a total of 76-80 ft-lb (100-110 N·m).
