4.2 INLET FITTINGS OR EXTEND-A-GUN RC INSTALLATION
The Hurricane RC Monitor is available with various inlet fittings as shown in figure 3.3. The Hurricane RC Monitor also connects directly
to TFT's Extend-A-Gun RC3 or RC4. The fittings and Extend-A-Gun RC are attached to the monitor by means of a threaded joint with an
o-ring seal. Once in the proper orientation, the threaded joint is locked from rotation by two ¼-28 button head cap screws as shown in
figure 4.2A. This makes for easy removal of the monitor, since the large threads of the joint are not tightened and do not have any thread
locking compounds on them. It is best to install the inlet fitting or Extend-A-Gun RC to the apparatus and than install the monitor to the
inlet fitting or Extend-A-Gun RC. This gives more room to install the bolts in the case of flanged fittings. Referring to figures 4.2A and
4.2B, the installation sequence is as follows:
1) Install inlet adapter or Extend-A-Gun RC to apparatus.
•
Mount so that 180 degree apart threaded cross holes will give desired direction relative to the “Straight Back Reference Mark”
when the monitor is installed.
2) Screw monitor onto inlet adapter or Extend-A-Gun RC until threaded joint bottoms out.
•
Do not use pipe dope or Loctite on the inlet base threads. These threads are sealed with an o-ring. The use of thread locking
compounds will make removal difficult.
3) Unscrew monitor slightly until a pair of 90 degrees apart slots line up with the 180 degrees apart threaded cross holes in the inlet
adapter or Extend-A-Gun RC.
•
Orient monitor so that the Straight Back Reference Mark is facing the desired direction.
•
Slots will line up with threaded cross holes every 90 degrees of rotation.
•
Monitor may be unscrewed up to one full turn from the bottomed out position.
4) Install ¼-28 by ½ long button head cap screws and washers in the two threaded cross holes.
