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

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).

4.2 INLET MOUNTING AND TRAVEL RANGES

4.2.1 INLET FITTING OR EXTEND-A-GUN RC INSTALLATION
The Monsoon Monitor is available with various inlet fi ttings as shown in fi g 3.3. When the inlet fi ttings are used see fi gure 4.2.1A
for the addition to overall height. The Monsoon Monitor also connects directly to TFT's Extend-A-Gun RC3 or RC4. The fi ttings and
Extend-A-Gun RC are attached to the monitor by means of a threaded joint with an o-ring seal. Two different methods of rotational
locking between the Monitor Base and the Inlet adapter or Extend-A-Gun Inner Tube exist. One method relies on two ¼-28 Button
Head Screws, and the other, newer version, uses a two-piece Clamp that is held together with #10 Cap Screws and Cylindrical nuts.
The rotational locking method employed can be identifi ed by the presence or absence of two threaded cross-holes, 180 degrees
apart in the threaded portion of the Inlet Adapter or Extend-A-Gun Inner Tube, where the monitor screws on. If ¼-28 Screws are
needed, there will be ¼-28 threaded cross-holes in the threaded portion of the Inlet Adapter or Extend-A-Gun Inner Tube. If Clamps
are needed, there will be no ¼-28 threaded cross-holes in the threaded portion of the Inlet Adapter or Extend-A-Gun Inner Tube.
Once the necessary rotational locking method is determined, install the monitor using one of the following procedures.
TWO PIECE CLAMP ROTATIONAL LOCK INSTALLATION INSTRUCTIONS
(without tapped holes):
1) Assemble Clamps and place loosely on Inlet Adapter or Extend-A-Gun.
A) Apply VSA-125 blue Loctite to threads on Cylinder Nut.
B) Loosely install Screws, Washers and Cylinder Nuts on Clamp.
C) Grooves on heads of Cylinder Nuts indicate alignment of threaded
holes.
D) Place Clamp assembly over male threads of outlet.
E) Heads of Cylinder Nuts must be on top side of Clamps.
2) Screw monitor onto Inlet Adapter or Extend-A-Gun RC until threaded joint
bottoms out.
A) CAUTION: Make sure the Clamps are not tight enough to prevent
the monitor Base from bottoming out. The monitor will leak if it does not
bottom out in this step.
B) DO NOT USE PIPE SEALANT OR LOCTITE ON THE INLET BASE
THREADS. These threads are sealed with an O-ring. The use of thread
locking compounds will make removal diffi cult.
3) Unscrew monitor until the "Straight Ahead Reference Mark" is facing the
desired direction.
A) Monitor may be unscrewed up to one full turn from the bottomed out
position.
B) CAUTION: Monitor will leak if unthreaded more than one full rotation
from bottomed-out condition.
4) Rotate the Clamps to the desired orientation.
A) Ensure that Clamp assembly does not interfere with RC monitor Power/
Com Cable.
4) Tighten each Screw gradually until both are fi nger tight with approximately
equal spacing between opposite ends of Clamps.
5) Carefully tighten each Screw one additional turn using a 5/32 hex wrench
by alternating to the opposite Screw in half turn increments.
A) CAUTION: Over tightening the Screws will damage Screws and
Clamps.

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.
