4.0 INSTALLATION
See Remote Control (RC) Monitor Electrical Controls Supplemental Instructions (LIY-500) For RC monitor.
4.1 STRUCTURAL REQUIREMENTS
The structure that the EF1 RC 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 150 lbs (70 kg) (200 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 in figure 4.1. Tighten sequentially each bolt or stud
three times with 30%, then 60%, and finally 100% of the specified
torque. Tighten to 76-80 ft-lb (100-110 Newton-Meters).

4.2 TRAVEL RANGES
The EF1 RC Monitor is available with various inlet fittings. These Inlet Adapters must be oriented upon installation so the EF1 RC will
point in the desired direction. Figure 3.4A shows examples of Inlet Adaptors. Travel ranges relative to the Straight Ahead Reference
Mark are shown in Figure 4.2. Figure 4.2.1 gives the location of the travel stops.
