4.0 INSTALLATION
4.1 STRUCTURAL REQUIREMENTS
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 1100 lbs (500 kg)(1500 gpm at 200 psi).
For flanged connections, the use of flat flanges without raised faces is recommended. Use a ring gasket as defined in ASME 16.21 or
ISO 7483. Tighten flange bolts in an alternating sequence as shown below. Tighten sequentially each bolt or stud three times to 30%,
then 60%, and finally 100% of the specified torque. Tighten to a total of 76-80 ft-lb (100-110 N·m).

WARNING
Reaction forces generated by master stream flows are capable of causing injury and property
damage if not properly supported. Monitors should be securely installed by qualified 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 flanges or pipe made from plastic for monitor mounting.
• Torque all fasteners to specified values.
