8393IV(2.0) “STINGRAY” MONITOR INSTRUCTIONS
Installation:
1) Install monitor on riser pipe terminated with a companion flange or male pipe thread that matches
the monitor inlet base. If the monitor has a 3” pipe thread base (NPT female), the minimum thread
engagement should be 3/4”, or six (6) threads.
2)
The riser MUST be strong enough to withstand the reaction force of the nozzle when flowing a
straight stream parallel to the ground. The maximum allowed reaction force for this monitor is 632
lbs. Use the friction loss for the monitor (and stream shaper if used) together with the available
pressure and flow from your water supply to determine the pressure at the base of the nozzle that
you intend to use with this monitor Use one of the reaction force formulae below to determine that
the reaction force of this monitor/stream shaper/nozzle combination does not exceed 632 lbs. This
monitor is designed for a maximum flow rate of 1250 GPM (US).
3) MONITOR INLET PRESSURE NOT TO EXCEED 200 PSI. If Monitor inlet pressure causes
reaction force to exceed 632 lbs or is above 200 psi an orifice plate must be used at the monitor inlet
to bring the reaction force or monitor inlet pressure in line with the parameters described above.
Operating:
1) The monitor discharge can be raised to 90 degrees (70 degrees w/optional pressure gauge) above
horizontal by turning the hand wheel in a counter-clockwise direction. It can be lowered to 60
degrees below horizontal by turning the hand wheel in a clockwise direction.
2) The discharge can be rotated horizontally by releasing the horizontal twist-lock knob at the lower
right and rotating the monitor. Turn the knob counter-clockwise to release or clockwise to engage.
3) When monitor is left unattended, ALWAYS lock the horizontal movement.
4) Because of the worm gearing on the vertical movement, no lock is needed. The vertical discharge
will stay in the position in which it was last set.
