114.2 INLET FITTING OR EXTEND-A-GUN RC INSTALLATIONThe Monsoon Monitor is available with various inlet fittings as shown in fig 3.3A. When the inlet fittings are used see figure 4.2A for theaddition to overall height. The Monsoon 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 islocked from rotation by two ¼-28 button head cap screws as shown in figure 4.2B. This makes for easy removal of the monitor since thelarge 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 orExtend-A-Gun RC to the apparatus and than install the monitor to the inlet or Extend-A-Gun RC. This gives more room to installthe bolts in the case of flanged s. Referring to figures 4.2B and 4.2C the installation sequence is as follows:1) Install inlet or Extend-A-Gun RC to apparatus.• Mount so that 180 degree apart threaded crossholes will give desired direction relative to the “Straight Ahead Reference Mark”when the monitor is installed. See figure 4.2B.2) Screw monitor onto inlet 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 lockingcompounds will make removal difficult.3) Unscrew monitor slightly until a pair of 90 degree apart slots lines up with the 180 degree apart threaded crossholes in the inletor Extend-A-Gun RC.• Orient monitor so that the Straight Ahead Reference Mark is facing the desired direction.• Slots will line up with threaded crossholes 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 crossholes. Use Loctite #271 on the threads of thebutton head cap screws.fittingfittingfittingfittingfittingAllow Loctite to fully cure before applying water pressure.MODEL INLET FITTING ADDITIONALTYPE HEIGHTY4-*1*A 3" ANSI 125/150 0.75"DN8, PN20 20mmY4-*2*A 4" ANSI 150 0.94"DN100, PN20 24mmY4-*4*A DN80, PN16 0.75"20mmY4-*5*A DN100,PN16 0.94"24mmY4-*6*A 3" NPT FEMALE 2.00"51mmY4-*7*A 4" NPT FEMALE 1.75"45mmY4-*8*A 3" BSP MALE 2.30"58mmY4-*9*A 4"BSP MALE 2.30"Fig 4.2A Additional Height for Inlet FittingsFig 4.2B Inlet Fitting Connection
